Little knowledge of children's teeth

Teeth are important organs for human survival, which are the main part of chewing organs, and are also closely related to language, appearance and health. Besides brushing your teeth every morning and evening and gargling after meals, there are some effective self-care measures to protect your teeth.

first, pick your teeth.

In the process of chewing food, food fibers (such as leek, celery, lean meat, etc.) are often caught between teeth, which are harmful to teeth and periodontal tissues, and should be removed in time, but care should be taken not to pick teeth too often, so that the teeth may be enlarged.

second, often knock your teeth.

since ancient times, people who are good at keeping in good health have emphasized that "teeth should be knocked frequently". Clear and clear, the diet is not advanced, and the teeth and gums are not filled. Gently tapping the teeth can promote the smooth blood vessels and protect the teeth. "clearly knock your teeth thirty-six, and the old teeth will not fall." The method is to "slightly close the lips, first knock on the molars 5 times, then knock on the front teeth 5 times, and then knock on the wrong teeth 5 times, once a day in the morning and evening.

third, chew correctly.

The correct way to chew is to use teeth alternately on both sides.

fourth, correct bad habits.

Some infants have the habit of sucking their thumbs, licking their teeth, grinding their teeth, breathing with their mouths open, biting their lips, and so on, resulting in malocclusion of their teeth. Correcting bad habits is beneficial to dental care, and teeth should be corrected as soon as possible.

5. drink tea and water often.

Tea contains fluorine, which can prevent dental caries. Drinking tea water often or gargling with tea water can protect teeth and clean mouth.

6. Take certain drugs carefully.

Tetracycline, gold toxin and other drugs can make teeth yellow or enamel hypoplasia, which is easy to cause dental caries in the future. Therefore, pregnant and lactating women and infants should not take these drugs in large quantities or for a long time.

7. Wide recipes and good nutrition.

The development of teeth can't be separated from various nutritious foods. Therefore, regardless of adults or children, the diet should be diversified and not partial to food.

eight, protect your teeth.

The kidney dominates the bone, while the teeth are the bone. If the kidney essence is abundant, the teeth will develop politically and grow firmly. Therefore, nourishing kidney and storing essence is also a means of self-care of teeth.

IX. Prevention of trauma.

don't use your teeth to open hard objects such as bottle caps to prevent tooth damage.

2. Love your teeth and protect your teeth

Alcohol is an enemy that hinders fresh breath, so we should try to avoid drinking alcohol or using mouthwash containing alcohol. Regular tooth cleaning:

Toothcleaning is to remove tartar hidden around the tooth flesh and stains on the tooth surface, such as tea stains, coffee stains and cigarette stains. However, it should be noted that some stains can not be removed, such as stains that go deep into tooth lines. Habitual use of dental floss: < P > In the case of red, swollen and inflamed teeth, it is easy to cause bleeding in the process of tooth washing or brushing. Please don't worry, if you can use dental floss and electric toothbrush correctly and adopt effective brushing methods, the inflammation and bleeding of teeth can be improved. Master the correct method of brushing teeth:

Use a reasonable toothbrush, brush your teeth vertically, and brush them both inside and outside. Rinse your mouth carefully after meals:

Rinsing your mouth can remove food crumbs and some soft dirt, keep your mouth clean and give full play to its physiological functions. Full chewing:

Especially eating foods with high vitamin content can secrete saliva, wash away dirt in the mouth, play the role of gum, and make teeth clean and periodontal tissue healthy. Tap teeth:

Tap teeth ten times every morning to enhance the resistance of teeth and periodontal tissues. * * * Gums:

Put your cleaned fingers on your gums and gently press them. You can brush your teeth in the morning and evening for a few minutes. Eat less sulfur-containing food:

According to scientific research, foods containing a lot of sulfur, such as milk products, onions and garlic, are prone to produce anaerobic bacteria that cause bad breath. Choose xylitol for chewing gum:

Actually, chewing gum containing sugar is more likely to cause tooth decay or breath. Therefore, choosing chewing gum containing xylitol can effectively strengthen teeth and ensure fresh breath. Fresh breath, speaking will not be "aggressive" and it is also necessary for your interpersonal public relations.

3. Tell me more about the common sense of children during tooth changing.

Usually, at the age of 6~7, the deciduous central incisors (central incisors) of the mandible begin to shake and fall off, and soon, they grow permanent central incisors here. At the same time, the first molar grows behind the second deciduous molar.

Since then, other teeth have been replaced one after another. Monocusps and bicuspids of permanent teeth can only grow after deciduous teeth in the same position fall off.

until the age of 12~13, all the deciduous teeth fell off and the permanent teeth were replaced. After that, single permanent teeth: the second molar grows behind the first molar at the age of 12~14, and the third molar grows after the age of 18.

It is normal for some people to have no third molar. Problems that should be paid attention to during tooth replacement: deciduous teeth should be dropped but not dropped. Doctors call this phenomenon deciduous teeth retention, so children should be taken to the hospital for examination and treatment in time.

main reason: dislocation of permanent teeth embryo, local inflammation, loss of permanent teeth embryo, and the remaining teeth with erupted permanent teeth but not deciduous teeth should be pulled out as soon as possible to avoid affecting the eruption of permanent teeth in the normal position. Don't pull out the deciduous teeth if they are over the age of tooth replacement and the permanent teeth don't erupt. If the permanent teeth are congenital missing, try to keep the deciduous teeth.

premature loss of deciduous teeth: deciduous teeth fall off before they should fall off, which is called premature loss of deciduous teeth. It often causes the adjacent teeth on both sides to tilt to the gap of missing teeth, which makes the gap of missing teeth smaller and the permanent teeth erupt out of position because of insufficient gap.

A gap retainer should be worn at the gap of deciduous teeth to prevent the teeth on both sides from inclining until the permanent teeth erupt. Difficult eruption of permanent teeth: permanent teeth produce eruption force during root development, which makes permanent teeth move to gingival side and erupt gradually. This requires a process, especially for upper teeth.

permanent teeth do not erupt after the period of tooth replacement, which is called delayed eruption of permanent teeth. The main reasons are: the early loss of deciduous teeth, the obstruction of odontoma or cyst, the abnormal development of permanent teeth, genetic factors, tooth dislocation occlusion: tooth replacement during tooth changing, jaw development, gradual establishment of occlusion relationship, and sometimes temporary dislocation occlusion, which often adjusts itself to return to normal during tooth development.

Some malocclusion can't be adjusted by itself, which will affect the facial development, so we should go to the hospital for diagnosis and treatment. Double-layer teeth: permanent teeth come out before deciduous teeth fall off, which is not uncommon. This is probably caused by the root of deciduous teeth not being completely resorbed.

The relative position of deciduous teeth and permanent teeth can be determined by oral X-ray, so as to diagnose whether deciduous teeth fall off or need to be pulled out. It hurts a little when changing teeth: the process of loosening and falling off teeth generally doesn't hurt, but with the deciduous teeth beginning to fall off, "six-year-old teeth" will grow out, which may cause gum swelling and make children complain about toothache.

If the pain is serious, you need to see a dentist to see if you need to relieve inflammation and pain. Six-year-old tooth decay: About 6 years old, behind the second deciduous molar, the first permanent molar grows quietly, also called "six-year-old tooth".

it doesn't replace any deciduous teeth, and it is easy to mistake it for deciduous teeth. Clinically, it is found that many children have six-year-old teeth caries, which have developed into pulpitis or apical periodontitis.

In order to prevent caries of six-year-old teeth, pit and fissure sealing should be done as soon as possible. With the increase of age, children should eat more chewy foods such as jellyfish, peanuts, sugar cane, spiced beans, etc., so as to maintain a good effect on deciduous teeth and promote them to fall off on time.

When children are about 1 years old, their front incisors and back molars have sprouted. Parents can give them some celery stalks, corn, apples and other foods, so that the tooth replacement can be completed smoothly and the children can have a healthy and tidy permanent tooth. Prevention of inferiority complex during tooth replacement The self-esteem of children during tooth replacement has been established. I care about whether the front teeth look good or not.

If you make fun of this, children will feel inferior, and even lick their teeth desperately in the hope of growing up soon, but the result is counterproductive. You can tell children that white swans are all transformed from ugly ducklings. The loss of front teeth and ugly appearance is a process of transformation, which proves that "you are about to grow up", and every child has to go through this process when growing up.

4. Tips for loving teeth

Brush your teeth in the morning and evening and after meals.

change a toothbrush every three months. Brush your teeth with warm water of about 36℃, which is similar to the temperature of your mouth. Brush your teeth with different toothpastes.

key tooth food

The ingredients in some natural foods can fight against oral bacteria that cause tooth decay and strengthen tooth enamel.

tea: the fluorine contained in tea can be combined with apatite tuberculosis in teeth, which has the effect of acid resistance and tooth decay prevention. Among them, oolong tea and green tea have the highest fluorine content. Polyphenols contained in it are a complex composed of more than 3 substances, which have the efficacy of disinfection and sterilization, can reduce Streptococcus mutans causing tooth decay in the oral cavity, and have the effect of tooth fixation. Drinking tea regularly increases the flow of water and liquid in the oral cavity and maintains oral hygiene. Sugar, pectin and other components in tea have a chemical reaction with saliva, which moistens the mouth and enhances the self-cleaning ability of the mouth. Chewing tea can also cure gum bleeding. However, it should be noted that when chewing, it should be chewed carefully, so that the tea leaves can be ground and chewed into fine powder in the mouth, and then the saliva can be swallowed.

Onions: Onions, especially fresh raw onions, can kill many kinds of bacteria, including Streptococcus mutans, which causes tooth decay.

Lentinus edodes: The lentinan contained in Lentinus edodes can inhibit bacteria in the mouth from producing dental plaque.

Mustard: Mustard contains some ingredients that can inhibit the reproduction of Streptococcus mutans, which causes tooth decay.

celery: coarse fiber food can sweep away some food residues from teeth. In addition, hard chewing can secrete saliva, balance the pH value in the mouth, and achieve natural antibacterial effect. In addition to celery, sliced cucumbers and carrots can also play the role of gums.

drinking water is the simplest but important way to protect teeth. Drinking water in moderation can make our gums moist and powder saliva. Drinking some water after eating can take away the food residue in the residual mouth and prevent the bacteria that damage the teeth from getting nutrients.

sugar-free chewing gum. Chewing sugar-free chewing gum with "xylitol" has obvious effect on inhibiting bacteria causing dental caries.

Key-tooth movement

Chewing: Chewing foods with appropriate hardness, elasticity and high cellulose content, such as coarse grains, miscellaneous grains, vegetables and fruits, can exercise the chewing ability of oral muscles and teeth, and make tooth tissues tough and firm, and not easy to loosen. Chewing food fully when eating can * * gum, scrub tooth surface and bounce periodontal ligament, which can accelerate blood circulation, improve local nutrition and promote dental health.

*** Gums

Sticking to the teeth for 5 minutes every day can promote blood circulation and tissue metabolism, exercise muscles and protect the skin, promote saliva secretion and clean the mouth, so as to achieve the purpose of strengthening teeth and exercising periodontal function. If the teeth are slightly loose, you can use your index finger to gum for 1 minutes every morning. You can also roll the nucleus up and down in your mouth when you talk about plum or apricot, which is of great benefit to prevent periodontitis and strengthen your teeth.

Tooth habit

Many people have the habit of brushing their teeth immediately after meals, thinking that this can reduce the chance of dental diseases as much as possible. However, recent research shows that brushing your teeth immediately after meals is harmful to your teeth health. This is because there is a layer of enamel on the surface of the crown, and the enamel will become soft after eating a meal, especially after eating acidic food. Brushing your teeth at this time will cause enamel damage. Therefore, it is best to rinse your mouth with clear water after eating, and then brush your teeth after 1-2 hours.

5. What is the common knowledge of oral hygiene of primary school students

The harm of dental caries

1. It affects chewing function;

2. Adverse effects on the development of permanent teeth: when deciduous teeth are deeply decayed, it can directly affect the growth of corresponding permanent tooth germs, resulting in permanent tooth caries that erupt after tooth replacement;

3. It can cause systemic infectious diseases: the dental pulp cavity contains rich vascular network connected with the systemic capillary network, and bacteria can spread to other parts of the whole body along its vascular network after dental pulp infection;

4. Adverse effects on facial development: because the affected tooth side is not conducive to chewing, excessive chewing of the other tooth can cause the development of the jaw of this side and the development of the opposite jaw is slow, resulting in asymmetry of the face;

5. Influence on aesthetics and pronunciation: Teeth, vocal cords and tongue together constitute the human pronunciation system. The premature loss of teeth due to caries will affect correct pronunciation and speech, and the caries and loss of dentition will also affect aesthetics.

how to prevent tooth decay

even if bacteria decompose food in the mouth to form acidic substances, it will take some time for acidic substances to act on teeth to decompose enamel to form cavities. As long as the toothbrush is cleaned immediately, so that acidic substances do not contact with teeth for a long time, there will be no tooth decay, so it is very important to rinse your mouth and brush your teeth in time after eating. Plaque is most likely to form at night, so brushing your teeth before going to bed is particularly important.

oral hygiene knowledge 3: tooth changing

order of deciduous teeth falling off

1. Central incisors-6-7 years old

2. Lateral incisors-7-8 years old

3. Canine teeth-1-12 years old

4. First deciduous molars-9- In this case, parents should take their children to the hospital as soon as possible to remove the stranded deciduous teeth and make room for the eruption of permanent teeth;

2. Pay attention to whether it is difficult for permanent teeth to erupt: deciduous teeth fall off prematurely, and children are used to chewing and licking with their gums, which will become thick and tough and hinder the eruption of permanent teeth. Calcium deficiency in children is also an important cause of delayed eruption of permanent teeth. Therefore, if the child has reached the age of changing teeth and the permanent teeth have not yet grown, he should take the child to the hospital for examination in time.

3. Pay attention to children's oral hygiene: during tooth replacement, deciduous teeth and permanent teeth exist, and the permanent teeth just erupt, and there are many pits and grooves on the occlusal surface, which are easy to retain food residues. In addition, children don't like brushing their teeth and love sweets, and their teeth often get decayed. At this time, the most important thing is to teach children the correct way to brush their teeth.

4. Pay attention to correct the child's bad habits: During the tooth changing period, when the deciduous teeth are loose and about to fall off, the child is often used to licking the loose teeth with his tongue. This is a bad habit, which will affect the normal eruption of permanent teeth and cause malocclusion, that is, the teeth are not arranged neatly. Parents should correct it in time.

5. Correction of malocclusion: Some malocclusion is due to pathological reasons, such as the gap between the upper teeth is too large due to the low position of the labial frenum of the upper lip, which can not be adjusted by itself, which will affect the facial development. You should go to the hospital for correction, otherwise it will affect the child's appearance.

6. Love your teeth and protect your teeth 2

To protect your teeth, you must first understand the structure of your teeth.

teeth are the hardest organs in the human body. It has the functions of biting, tearing, grinding food and assisting pronunciation.

There are two pairs of teeth in a person's life: one is deciduous teeth, with 2 teeth and 1 teeth in the upper and lower jaws. It begins to sprout at about half a year after birth, and comes out at about two and a half years old, from 7 to 12.
