1. Tips on protecting your teeth

---The following is copied from the Internet, take a look at it yourself---

Protect your teeth from a young age< /p>

Babies should be taught to protect their teeth and prevent oral diseases from an early age. Generally, children can be educated on oral health care starting from the age of 3 years old.

Tell your baby to be hygienic, love to be clean, brush his teeth in the morning and evening, rinse his mouth after meals, eat less sweets, eat more fruits and vegetables, not to eat snacks before going to bed, not to be picky or picky about food, and other simple oral health knowledge , let your baby understand the meaning of oral health care.

Mom and dad can arouse the baby's curiosity by telling stories (such as the story of "Little Bear Pulling Out Teeth"): "Why does Little Bear have toothache? How should I protect my teeth?", or use pictures or Interesting children's songs teach babies about their own teeth. For example, the teeth that grow out after birth are called deciduous teeth. When they are 5 to 6 years old, the deciduous teeth begin to fall out slowly and new teeth grow, called permanent teeth.

If permanent teeth are decayed or knocked out, they will not grow back. Therefore, you must protect your teeth from an early age, pay attention to dental hygiene, and let your baby understand the importance of brushing and gargling.

Brush your teeth with warm water, which greatly reduces the exposure to cold and heat. It can protect your teeth and reduce the occurrence of dental diseases, especially for people with tooth allergies, dental caries, periodontitis, oral ulcers, and glossitis. , patients with strep throat are more beneficial. When your baby gradually gets used to brushing his teeth twice a day, morning and evening, you can start letting him try brushing his teeth with toothpaste. Note that when brushing your teeth with toothpaste, rinse the toothpaste foam in your mouth with water.

Five principles for protecting teeth

1. Eat a balanced diet

Eat a balanced diet, do not have a partial eclipse, and choose foods that are good for oral health, including: whole grains, milk, fish Eggs, fresh vegetables and fruits, etc., eat less sour, sweet and sticky foods, drink less sweet drinks, eat less snacks or no snacks.

2. Brush your teeth in the morning and evening

Brush your teeth to remove plaque. The bacterial film that adheres to the tooth surface is the main factor causing dental caries and gum inflammation.

3. Choose dental appliances carefully

Choose a health care toothbrush suitable for young children and use cleaning and sanitary dental appliances.

4. Brush your teeth correctly

The correct way to brush your teeth is the vertical brushing method (brush along the gaps between the teeth): brush the upper teeth downward, brush the lower teeth upward; brush left and right Brush outwards, avoid brushing left and right.

5. Regular check-ups

Go to the dental hospital to check your teeth every six months or a year to prevent and treat diseases early.

Tips for protecting your teeth

1. After brushing your teeth with fluoride toothpaste, you do not need to rinse the foam out of your mouth;

2. Chew xylose Alcoholic chewing gum can neutralize oral acidity and prevent tooth decay, but you still need to brush your teeth;

3. Smoking is a high risk factor for oral cancer and periodontitis, and you should quit smoking;

4. Standard dental cleaning will not harm the teeth. If possible, teeth cleaning should be done every six months.

2. Little knowledge about teeth

Children have 20 teeth, called deciduous teeth. Around the age of 6, deciduous teeth will gradually be replaced by permanent teeth. By the age of 12-13, there are 28 permanent teeth, and after the age of 18, there are 32 third permanent molars. The protection of deciduous teeth has an important impact on the eruption of permanent teeth. If care is not taken to protect deciduous teeth, it will directly affect the growth and development of permanent teeth in the future. It is often seen that some children's teeth only have black roots left, which not only affects eating, but also often causes swelling and pain in the gums. Inflammation and swelling of children's teeth can cause:

1. Local inflammation caused by bad teeth can affect the growth and development of permanent tooth germs. Inflammation of the growing permanent tooth germ may cause developmental abnormalities, such as various dental deformities.

2. The main symptoms of bad teeth are toothache and tooth root swelling and pain. Toothache affects children's ability to eat, and sometimes pain at night affects the rest of the family.

3. Repeated inflammation of bad tooth roots causes uneven dentition of permanent teeth.

Because children are still young and do not know how to protect their teeth and develop good oral hygiene habits, parents are asked to educate and urge their children to develop good oral hygiene habits.

1. Cultivate children with good tooth brushing habits. Brush your teeth twice in the morning and evening. Teach your baby the correct way to brush his teeth: The correct way to brush his teeth is the vertical brushing method. The benefits of vertical brushing are: it causes less damage to the teeth, has a positive effect on the gums, and can promote blood circulation in the gums.

2. If a child has dental caries, he should be taken to the dentist for examination and treatment in time.

3. Eat a balanced diet and eat more vegetables and fruits to enhance the disease resistance of the oral mucosa and maintain the health of teeth and periodontal tissues.

Brush your teeth at least twice a day

Rinse your mouth for at least three minutes each time and be sure to rinse thoroughly

Otherwise, swallowing it will not be good for your stomach

Change the type of toothpaste frequently and don’t always use the same toothpaste

Visit your dentist every six months

When brushing your teeth, brush from the inside out and brush your teeth in an up and down direction to avoid a saw-like brushing< /p>

Question: Why do I have toothache (tooth neuralgia)?

Answer: Generally, severe toothache may be caused by tooth nerve inflammation or even gradual necrosis caused by tooth decay, bite injury or trauma. At this time, the best treatment is root canal treatment. If you just "apply" medicine or use a nerve killer, it will only temporarily relieve pain. Moreover, this is only effective when the tooth has been decayed to the point where the tooth nerve is exposed. If the nerve pain is caused by trauma or bite injury, then relying solely on " Injecting medicine or applying medicine will not help at all.

Question: How do you know if you have tooth decay?

Answer: The appearance of black spots and small holes on the tooth surface usually indicates that tooth decay occurs in the enamel, but the patient will not feel any symptoms such as soreness. When caries extend into the dentin, patients will feel sore when eating cold or sour food. If dental caries penetrates deeper into the dental pulp, it will lead to pulpitis, which will be extremely painful and may even prevent you from eating normally, affecting your overall health.

Although tooth bruises, tooth cracks, bite wear, abrasion, periodontal disease or the collision of different metal fillings causing electrical conduction, etc., may cause toothache. However, the most common cause of toothache is tooth decay! Of course, the best way is to see a dentist for regular check-ups every six months. The dentist will use a probe to find the cavities on the surface of the teeth. As for some cavities on the adjacent surfaces of the teeth, they can be detected through Bite-Wing X-rays. Check for cavities.

Question: Why do tooth decay occur?

Answer: Bacteria, food, host (teeth) and time are the four main factors that cause tooth decay.

Bacteria: Streptococcus mutans.

Food: The type, quantity and viscosity of the sugar contained determine the amount of acid produced.

The shape and arrangement of teeth affects how long food sticks.

Time: the number of times of feeding and the length of each feeding.

The "bacteria" in dental plaque or saliva in the human oral cavity use sugar fermentation as "food", produce acid after metabolism, and come into contact with "teeth" for a long time, thereby destroying teeth. The surface of the tooth causes decalcification and caries, which is the so-called tooth decay.

Question: Prevent tooth decay?

Answer: Now that we know the causes of tooth decay, we will take precautions against each cause: After eating, brush your teeth immediately and use dental floss to thoroughly remove food residues to remove "food "This factor! Reduce the chance of forming dental plaque and try to keep "bacteria" and "food" from meeting! "Teeth" are no longer exposed to a dirty environment for a long "time", which reduces the occurrence of tooth decay. Having said that, please go to the dental clinic regularly for health checkups!

3. What are some tips for young children to protect their teeth?

Tips for young children to protect their teeth: 1. Feeding should be done regularly and quantitatively so that children can develop good eating habits from an early age and strengthen their gastrointestinal tract. Digestive function, good digestion and absorption, the child's teeth will grow healthier. This is a virtuous cycle.

2. Overcome the habit of partial eclipse and ensure balanced nutrition. Add complementary foods to the baby in a timely manner to correct the bad habit of the baby with partial eclipse. Ensure that the baby receives sufficient and balanced nutrition to ensure the normal structure and shape of the teeth and improve tooth alignment. Resistance to dental disease. In addition, when the baby's deciduous teeth erupt, attention should be paid to supplementing nutrients such as calcium, phosphorus, and vitamin C. This can promote the development and calcification of the baby's teeth, ensure the health of periodontal tissue, and reduce the possibility of dental lesions.

3. Develop a correct feeding posture. When some babies are feeding, their mandibles will protrude or retract due to incorrect posture or improper positioning of the bottle. If this happens for a long time, it will lead to deformity of the baby's teeth and jaws, which will not only affect the baby's appearance, but also affect the development of chewing function.

When the baby is breastfeeding, the best position is semi-recumbent position, with the bottle and lips at a 90-degree angle, and the pacifier does not press the upper and lower lips. 4. Let the teeth do some exercises. Babies in the teething period especially like to bite people or hard things. This is because the deciduous teeth will squeeze the surrounding areas when they grow, causing the gum tissue to feel itchy and painful.

At this time, the mother can let the baby chew some harder things, such as biscuits, toast, apple slices, carrot slices, etc., on the one hand, it can relieve the discomfort of the gums, on the other hand, it can exercise the chewing muscles and promote Development of teeth and jaws.

4. Tabloids about tooth-loving knowledge should preferably have pictures, as well as tooth-loving knowledge, etc., all related to this

Nowadays, oral health has already become people’s overall health. It is an important part of the quality of life and an indispensable pillar for extending people's healthy lifespan.

Maintaining healthy teeth is not only regarded as a top priority for oral health, but many fashionable people are even proud of their white teeth. According to textual research, the oral hygiene habit recorded earlier in history - rinsing with salty water - was established by Confucius and compiled by later generations in the "Book of Rites". In the late Spring and Autumn Period, I started gargling with salt water every morning.

This method of protecting your mouth is also described in "A Dream of Red Mansions" by Cao Xueqin, a great literary master in the 18th century. A lady from a wealthy family like Lin Daiyu rubs it with green salt every night before and after going to bed and before meeting. It can be seen that gargling with salt water and brushing teeth was a relatively common method of protecting teeth in ancient my country.

The historical record of brushing teeth was written by Tang Shouxi. The ancient medical book "Waitai Mi Yao" was written in 752 AD. It records the ancient prescriptions before the Tang Dynasty and some new prescriptions at that time. It was once mentioned Bite one end of a poplar branch until soft, dip it in the medicine and wipe your teeth, which will make your teeth "smooth and smooth". This should be the earliest tooth-brushing habit in China. There are also scenes of brushing teeth with fingers in ancient Dunhuang murals.

Moreover, it is said that China is the first country to use toothbrushes. This can be verified by the cultural relics unearthed from the ancient tombs of the Liao Dynasty. The earliest toothbrush in the world appeared in China. Ancient monks also mastered this tooth-protecting technique. The Buddhist scripture "Huayan Sutra" even summarized chewing poplar branches as having 10 major benefits, including "removing tartar" and "promoting breath fragrance".

Monks clean their teeth in this way before chanting sutras. Li Shizhen, a famous doctor in the Ming Dynasty, also pointed out in his masterpiece "Compendium of Materia Medica" that using young willow branches "cut into tooth branches is very good for cleaning teeth."

●What foods can prevent dental caries? Foods such as fish, rice, lentils, peas and broad beans are high in phosphorus. Phosphate can form a buffer system to prevent excessive acidification of the mouth. Children should eat more calcium-rich foods such as beans, soy products, vegetables, fish, and shrimp to provide sufficient minerals and vitamins for normal tooth development.

Foods such as milk and dairy products contain a large amount of calcium. Calcium can inhibit the acid production of bacteria and prevent the calcium and phosphorus compounds in teeth from dissolving. In addition, the immunoglobulins and enzymes contained in milk can inhibit the growth of bacteria in the oral cavity.

Foods containing a lot of fluoride include fish, shrimp, kelp, and jellyfish, as well as tea and mineral water. Fluorine can combine with calcium and phosphorus compounds in dentin to form insoluble fluoroapatite. This prevents the acid produced by bacteria from eroding the dentin. You should eat more foods that are not cooked and processed too finely. Because they contain more fat-soluble vitamins and minerals, you need more chewing power when eating. Chewing can promote saliva secretion. In addition to helping digestion, it can also play a role in cleaning. The function of cleaning teeth.

You should eat less highly processed refined foods (such as plums, chocolate, soda, candies, pastries, biscuits, etc.). Fruits such as apples and pears can mechanically scrub the teeth when eating, wiping away bacteria adhering to the tooth surface.

In addition, the pectin in fruits also inhibits bacteria. Vegetables contain many trace elements and a large amount of vitamin C, which are also very important anti-caries nutrients.

Vegetable fiber can reduce the adhesion of food and the formation of dental plaque through mechanical friction and cleaning of tooth surfaces and secretion of salivary glands. In addition, vegetable oil can form a hydrophobic layer on the tooth surface, which can protect the teeth and prevent dentin from dissolving.

■Simple method → ??Use lemon juice to whiten teeth as follows: After brushing your teeth every night, dip some lemon juice into gauze and rub your teeth, and your teeth will become white and shiny. Lemon has strong cleaning power and whitening effect, and contains vitamin C, which can strengthen the roots of teeth.

To protect your teeth, students should do the following: 1. Develop good tooth brushing habits. Rinse your mouth with warm water after meals and brush your teeth once in the morning and evening.

Don’t brush your teeth too often, as too much will damage your teeth, and you shouldn’t brush your teeth for too long. 2. Pay attention to dental hygiene and protect your teeth.

Eat less candies on a daily basis. Especially don’t eat sugar before going to bed to prevent dental caries.

In addition, you should pay attention to your usual hygiene habits, do not bite your fingers, do not bite foreign objects such as pencil ends, and do not lick your teeth with your tongue. 3. If your teeth are diseased, you should seek medical treatment promptly.

In case of tooth decay or bad teeth, they should be repaired or removed. It is not difficult to achieve the above points, the key is to persevere.

I hope all students will have a pair of healthy and beautiful teeth. 1. Develop good eating habits: Reduce the frequency of eating sugary foods, because many bacteria accumulate on the edges of teeth and gums. When bacteria use sugar, they produce acid, which erodes teeth and causes dental caries.

2. Establish good oral hygiene habits: Keep your oral hygiene clean, master the correct brushing method, rinse your mouth after meals, and brush your teeth in the morning and evening. 3. Correct brushing angle and movement: tilt the toothbrush 45 degrees, press it between the tooth surface and the gums, try to insert the bristles into the gingival sulcus and between the teeth, then brush vertically along the tooth gap and gently rotate the brush head, do not use force. If it is too large, brush each tooth in sequence for three minutes each time.

4. Brush the outside of the teeth: Use correct brushing movements and appropriate angles to clean the outside of the upper and lower teeth. Brush the upper teeth from top to bottom and the lower teeth from bottom to top. Repeat for each part. Brush 4-6 times. 5. Brush the inside of the teeth: Still follow the principle of brushing vertically along the gaps between the teeth and rotating gently. Don’t only focus on brushing the outside of the teeth and ignore the cleaning of the inside of the teeth.

6. Brush the chewing surfaces of your teeth: Use appropriate force to brush the chewing surfaces of your upper and lower teeth in the front-to-back direction. 7. Pay attention to the teeth at the back: The teeth at the back of the mouth also need the same attention. After cleaning all the teeth, rinse your mouth with water.

8. Choose a health-care toothbrush and fluoride toothpaste: the bristles of a health-care toothbrush are soft and elastic and will not damage teeth and gums. The fluoride in fluoride toothpaste combines with tooth enamel to make teeth stronger and has a good anti-caries effect.

5. What are some tips on tooth care? Tips on tooth protection

If you want to protect your teeth, you must first understand the structure of the teeth.

Teeth are the hardest organs in the human body. It has functions such as biting, tearing, grinding food and assisting in pronunciation.

There are two sets of teeth in a person's life: one set is deciduous teeth, with 20 teeth in the upper and lower jaws, 10 in each. They begin to erupt about half a year after birth, and all appear at about two and a half years old. From 7 to 12 years old, the deciduous teeth fall out one after another; the other set is the permanent teeth, with 32 teeth, 16 in the upper and lower jaws, and 16 in the upper and lower jaws respectively. From the age of 12, deciduous teeth are gradually replaced, and by around the age of 12, all permanent teeth have erupted except for the third molars.

The third molars usually erupt after the age of 20, also known as wisdom teeth. Wisdom teeth may not come out for life, so 28 to 32 permanent teeth are normal.

A tooth is divided into three parts: crown, neck and root. The crown is the part of the tooth that we can see, the part of the tooth that is exposed beyond the gums.

The surface of the tooth crown is covered with a layer of enamel. Enamel is the hardest tissue in the human body, with a hardness similar to quartz. The tooth root is the part embedded in the alveolar process of the upper and lower jaw bones.

The surface of the tooth root is covered with a layer of cementum. The cervical portion of a tooth is the slightly thinner portion between the crown and root of the tooth, surrounding the gums.

Teeth are mainly composed of dentin, and the cavity inside is called the dental cavity. The living tooth cavity is filled with connective tissue, nerves and blood vessels, collectively called the dental pulp.

Blood vessels and nerves enter and exit through the apical foramen of the tooth.

When suffering from dental caries, when bacteria corrode the enamel and dentin into the pulp chamber and penetrate the nerve, the pain will be unbearable.

(See Figure 37) Students should protect their teeth by doing the following: 1. Develop good tooth brushing habits. Rinse your mouth with warm water after meals and brush your teeth once in the morning and evening.

Don’t brush your teeth too often, as too much will damage your teeth, and you shouldn’t brush your teeth for too long. Brush cheese? ⒁庹? Return to Mujiao and defeat Panⅲ? ? Are you searching for Lifu? 2. Pay attention to dental hygiene and protect your teeth.

Eat less candies on a daily basis. Especially don’t eat sugar before going to bed to prevent dental caries.

In addition, you should pay attention to your usual hygiene habits, do not bite your fingers, do not bite foreign objects such as pencil ends, and do not lick your teeth with your tongue. 3. If your teeth are diseased, you should seek medical treatment promptly.

In case of tooth decay or bad teeth, they should be repaired or removed. It is not difficult to achieve the above points, the key is to persevere.

I hope all students will have a pair of healthy and beautiful teeth. Good oral care isn't the only way to have healthy, beautiful teeth.

Eating habits also play a role that cannot be ignored. Here are some tips to help you have a beautiful smile! Your Teeth: A Major Sign of Health and Beauty Teeth allow us to enjoy a wide variety of foods! Healthy teeth allow us to chew hard food, meat, raw food, fruits without hesitation... Good chewing can strengthen the strength of the gums and promote saliva secretion, and they participate in the digestive process and sterilize the teeth role.

In addition to genetic factors, the color and hardness of our teeth also depend on dental care and dietary habits. To keep your teeth healthy: Eat a balanced diet! A well-balanced diet and well-distributed meals throughout the day (to avoid snacking, arrange four meals a day: breakfast, lunch, dinner and snack time) are very beneficial for strong teeth.

In fact, this helps our teeth better resist ***: enamel erosion, dental caries... When fresh food, such as carrots, red-skinned white radish or apples, is chewed, Rubbing on the tooth surface actually cleans the teeth. In addition, lipids, certain proteins (casein in cheese), minerals (phosphorus, calcium, fluorine...) and vitamin D have antibacterial effects and limit the excretion of inorganic salts from the enamel.

On the contrary, snacks, especially those "soft" foods, carbohydrate foods (candy or sweet drinks, bread, pastries...) or acidic foods (soda, fruit, juice), usually increase Danger of dental caries. Sugar can be converted into acid, which can damage the enamel on the surface of your teeth.

If possible, clean your teeth carefully after each meal. If you don't have the conditions, you can also rinse your mouth carefully or chew a piece of sugar-free gum.

In fact, any increase in salivary flow reduces the risk of tooth decay. It should be noted that excessive consumption of coffee, tea and excessive smoking may cause teeth to become yellow.

Four kinds of dairy products make teeth stronger. They are the best source of calcium and phosphorus we need, the main mineral materials for tooth enamel and tooth root supporting bone. Mineralization of primary teeth begins in the fourth month of pregnancy and mineralization of stone teeth begins in the first year of life.

After the tooth is formed, the enamel is renewed and remains so. We should drink milk and preferably not sweet drinks.

Dairy products (yoghurt, etc.) also bring calcium, phosphorus and vitamin D, which will increase the absorption of calcium and phosphorus. Finally, casein, the main protein in milk, can limit the excessive excretion of inorganic salts from tooth enamel.

In the past, people did a good job: they usually ate cheese after eating dessert, using the limiting effect of casein and the lipids in milk to reduce the acid secreted from carbohydrates. Drink more mineral water, which is a natural source of fluorine. Natural mineral water meets the body's demand for fluorine.

Fluoride can increase tooth enamel, strengthen teeth, and protect teeth from microbial erosion. Most mineral waters contain 0.3 mg of fluoride per liter, but some contain as much as 8 mg per liter.

We can also see fluoride salt on the table. For pregnant women and children, there are also tablets made with fluoride (0.5 mg to 1 mg, depending on age).

Fluoride is also contained in tea, marine fish and certain vegetables (spinach, red and white radish...). However, excessive fluoride intake (more than 2 mg per day) may cause teeth to become black.

Take advantage of the benefits of chocolate and sugar-free gum Cocoa actually contains tannins, fluoride and calcium phosphate. All three substances are involved in protecting teeth.

In "sugar-free" chewing gum, sucrose is replaced by polyols that are sweet, but do not cause dental caries: xylitol has a bactericidal effect and helps reduce plaque, and sorbitol (Sugars synthesized from glucose or fructose and used as artificial sweeteners). Therefore, a 2.2-gram piece of sugar-coated gum contains only 3.8 calories.

6. How to provide good dental care for children in kindergarten

For children who spend most of the day in kindergarten, dental care in kindergarten plays a decisive role. I think kindergartens should do the following in the dental care of young children.

1. Do a good job in the morning inspection. During the morning inspection, when the child opens his mouth, the health teacher can find many problems, such as whether to brush his teeth (check whether there is tartar on the teeth), whether to rinse after breakfast. mouth (check whether there are any physical residues), whether there is dental disease (small abscess spots on the roots of the teeth caused by dental caries or chronic apical periodontitis, etc.), whether there are double-layered teeth (the deciduous teeth have not fallen out, and the permanent teeth have erupted), if these occur If there is a problem, you can promptly provide children with dental protection and hygiene education or ask parents to take their children to the hospital for diagnosis and treatment as soon as possible. 2. Cultivate children to brush their teeth in the morning and evening, and form a good habit of gargling after each meal. Children in our kindergarten are required to rinse their mouths with warm water every morning, lunch and after lunch. The process is divided into three sips: the first sip of water is held in the mouth, and the child Puff your cheeks left and right, making a gurgling sound; rinse your throat with the second sip of water, making a gurgling sound; sip the third sip the same as the first.

The teacher on duty inspects and inspects to ensure the quality of children's mouthwash after lunch. However, it is not enough to just gargle in kindergarten. Home cooperation must be achieved first. Our kindergarten promotes the importance of protecting teeth and the correct method of brushing teeth to parents through the hygiene bulletin board, allowing parents to lead by example at home, so that children have the opportunity to imitate adults, so as to increase children's interest in brushing teeth.

Secondly, our kindergarten combines health education classes to teach children some knowledge about hygiene, so that children can master the correct brushing methods, and reminds parents to supervise and check. 3. Parents should cooperate in correcting children's bad habits. Children's teeth are still in the development stage. Only by absorbing sufficient and balanced nutrients can their normal development be ensured.

For children with picky eaters and partial eclipse habits, in addition to correcting them in kindergarten, we also ask parents to cooperate in changing the children's diet and making reasonable combinations so that children can eat foods rich in calcium, phosphorus, and vitamins. , and chew some chewy foods containing crude fiber appropriately. Bad habits such as nail biting, finger sucking, lip biting, mouth breathing, and unilateral chewing can cause children's teeth to be unevenly arranged. If these conditions are discovered, teachers should contact parents in a timely manner and work together to correct them.

4. Avoid dental injuries in young children. Violent activities and noise can easily cause trauma to teeth. In normal times, in addition to strengthening safety education for children, teachers should also take precautions and pay attention to protecting children's teeth to avoid bruises.

5. Regular oral examinations and caries prevention work. Our kindergarten conducts fluoride anti-caries treatment once a year, and conducts oral examinations on children once a year. If oral diseases are found, parents will be contacted promptly for early treatment to prevent their development. In addition, for children whose sixth-year-old teeth have erupted, sixth-year-old teeth and fissure sealing is performed to prevent dental caries.

7. Tips on protecting your teeth

Tooth protection. It is a very important part of beauty. Knowing why teeth

turn yellow or black is important. It is necessary to protect teeth.

When teeth turn yellow, brown or black, you should first identify the cause of tooth discoloration. Tooth discoloration is divided into two types: internal staining and external staining.

Intradental staining is tooth discoloration caused by changes in the tissue structure or nutrition of the tooth. Common ones include pulp necrosis, tooth discoloration caused by plaque and enamel and drug deposition.

When viewed from the longitudinal section of a normal tooth, the surface of the crown is covered by a milky white, translucent, lustrous and extremely hard structure. It protects the teeth because it is very similar to magnetic enamel. That’s why it’s called tooth enamel. Tooth

There is a thick layer of light yellow dentin structure inside the enamel that forms the main body of the tooth. There is dental pulp in the center of the tooth, which contains blood vessels, nerves, etc. to supply the nutrition and metabolism of the tooth. If the nutrition of the teeth changes or is cut off, the teeth will become discolored.

1. Tooth discoloration caused by pulp necrosis. If a tooth is traumatized and causes pulp bleeding and necrosis, the tooth will turn dark red,

brown or blue-gray.

2. Stained teeth are commonly known as yellow stains. Drinking water with a fluoride content of more than 1/1 million per liter of water before the age of 5 will cause the enamel of the teeth

The structure suffers from poor calcification and discoloration. In mild cases of tooth enamel, there are chalky or yellow-brown plaques on the enamel surface; in severe cases, the surface of teeth is rough, uneven, yellowish brown, or even black, and the teeth are brittle and easily damaged, making treatment more complicated. . For light plaques

the enamel dentist can apply dilute hydrochloric acid to the macular area to decolorize it, which can make the macula lighter. However, when applying the medicine, care should be taken to protect the gums and prevent corrosion and burns.

For teeth with heavy stains and enamel, "plastic dental veneers" or "light-cured composite resin" can be used to restore the shape and beauty of the teeth.

3. Drugs cause tooth discoloration. Mothers in the third trimester of pregnancy or children under 5 years old take more tetracyclines and oxytetracyclines.

Antibiotics combine with calcium to form yellow or off-white tetracyclines. , Geotoxin antibiotics combine with calcium to form a yellow or off-white

colored tetracycline calcium complex, which is deposited in the structure of enamel and dentin through the dental pulp, causing the erupted teeth to turn yellow.

Dark gray or dark brown. The preventive measure is to take as little tetracycline drugs as possible. Currently, pediatric tetracycline drugs have been included in the phaseout list.

External tooth staining refers to pigmentation on the surface of the tooth. For example, the pigments in smoking, drinking alcohol, drinking tea, and food mix with saliva

and then adhere to the tooth surface, especially the occlusal surface of the teeth, the grooves and pits of the lips and tongue are more likely to have pigmentation.

At this time, the tooth surface turns brown, yellow, gray or blue-green. People who are exposed to iron and sulfur for a long time due to occupational relationships may have brown pigmentation on their teeth. Tooth surfaces exposed to mercury for a long time may develop black pigmentation. Tooth surfaces that are in long-term contact with copper, nickel, and chromium may develop green pigmentation.

Brushing your teeth in the morning and evening and rinsing your mouth after meals can prevent tooth staining. For stained teeth, you can use a towel dipped in paste to rub the tooth surface, or use a cotton swab dipped in 3% hydrogen peroxide to scrub the tooth surface. In severe cases, the staining should be removed by a doctor's rubber wheel grinding.

8. "Toddler Teeth" lesson plan for young children

Healthy activities for large classes: Holes in teeth (kindergarten lesson plan)

Activity goals: 1. Know about acid Will corrode teeth; 2. Be able to name more than three dangers of dental caries; 3. Watch cartoons, learn the five steps of dental prevention, and know the correct common sense of tooth protection; 4. Cultivate good hygiene habits in children.

Activity preparation: 1. Egg shells, biscuits, cups, vinegar, mirror 2. Soak egg shells in vinegar with children two days before class; 3. Pictures of the process of producing dental caries and the five dental prevention strategies Pictures of the steps 4. One tooth model and one toothbrush each 5. Cartoon <> 6. Several word cards

Activity process:

1 , Rhythm enters the scene, leading to a situational performance; The tooth baby is crying. It turns out that his little master likes to eat sweets and does not brush his teeth. Over time, bacteria has drilled several holes in the tooth baby's body.

2. Find the causes of dental caries 1. The dental baby invites the children to eat biscuits, then rinses the mouth, and observes what changes happen to the clean water? (Knowing that people will have food residues left between their teeth after eating) Show picture 2. “There is a kind of bacteria in our mouths that will make these food residues sour (show pictures) If it takes a long time, our originally healthy teeth will What will happen? (Show the picture) 3. "There is an egg shell on the child's table. Tap it lightly with chopsticks. How does it feel? (Hardly) Let’s see what’s in the cup again? Those are the egg shells we soaked in vinegar two days ago. See what's happening now? 4. Discussion: Why do egg shells turn black and become soft? (Vinegar is acidic and will corrode the calcium in the egg shell, so the egg shell will turn black and soft.) 5. Teacher summary: There is a kind of bacteria in our mouths that will make food residues sour. Over time, these acids will Just like vinegar corrodes egg shells, it corrodes away the calcium in our teeth, and the teeth will turn black and produce cavities, also known as tooth decay. We also call it tooth decay. 3. What are the dangers of tooth decay? Learn the five steps of tooth protection and know the correct way to protect your teeth

4. Game "Protect Your Teeth All the Better" (End) Method: Choose one child to play the role of a 'cavity bug', and another child to play the role of a 'tooth decay bug' "Defender Jiajia", the other children acted as "teeth" and followed "Jiajia", the "cavities" went to catch the "teeth", and the "dental defenders" had to stop the "cavities" and protect the "teeth".
