Simple dental knowledge

1. Tips for caring for your teeth

Alcohol is a big enemy of fresh breath, so we should try to avoid drinking alcohol or using mouthwash containing alcohol. Regular teeth cleaning:

Teeth cleaning is to remove tartar hidden around the gum and stains on the tooth surface, such as tea stains, coffee stains and cigarette stains. However, it should be noted that some stains cannot be removed, such as stains that are deep into the tooth lines. Habitual flossing:

When the gums are red, swollen and inflamed, it is easy to cause gum bleeding whether during tooth washing or brushing. Please don’t worry. If you can use dental floss, electric toothbrush correctly, and adopt effective brushing methods, gum inflammation and bleeding can be improved. Master the correct method of brushing your teeth:

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

Rinsing your mouth can remove food debris and some soft dirt, keep your mouth clean, and better exert its physiological functions. Chewing fully:

Especially eating foods high in vitamins can stimulate saliva secretion, wash away dirt in the mouth, play the role of cleaning the gums, keep teeth clean, and keep periodontal tissue healthy. . Tap your teeth:

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

Place your clean fingers on your gums and press gently for a few minutes after brushing your teeth in the morning and evening. Eat less sulfur-containing foods:

According to scientific research, foods containing a large amount of sulfur such as dairy products, onions and garlic are prone to produce anaerobic bacteria that cause bad breath. Chewing gum should choose xylitol:

In fact, chewing gum containing sugar is more likely to cause tooth decay or bad breath. Therefore, choosing chewing gum containing xylitol can effectively strengthen teeth and ensure fresh breath. A fresh breath will prevent people from being intimidated when speaking, and it is also necessary for your interpersonal public relations.

2. Little knowledge about tooth protection

Draw a row of teeth. Write some knowledge about protecting teeth. Nowadays, oral health has long become an important part of people's general health and quality of life. It is also an indispensable and important pillar for extending people's healthy life span.

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 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. The method is as follows: After brushing your teeth every night, dip some lemon juice into gauze and rub the teeth, and the 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.

3. Tips on dental care

1. Drink more water. This natural mouthwash rinses away stains from coffee, soda, and red wine.

2. Make sure there is a certain proportion of fruits and vegetables in your daily diet. When eating crispy fruits and vegetables such as apples, celery, cucumbers and carrots, your mouth will be cleaned by the way, because the plaque and food residue between the teeth and gums will be removed by these fruits and vegetables.

3. Eat cheese. After dinner, chewing a piece of cheese can neutralize the acid in the mouth, ensure the acid-base balance in the mouth, and effectively protect the teeth.

4. Chew sugar-free gum.

Chewing gum can stimulate saliva production, help reduce acidic substances on the tooth surface, and strengthen tooth enamel. In addition, remember to brush your teeth after drinking a lot of acidic drinks, with the exception of orange juice and soda. They must wait at least 20 minutes before brushing, which can reduce damage to tooth enamel.

5. Clean with hydrogen peroxide. Rinsing your mouth with a small amount of hydrogen peroxide mixed with water can have obvious antibacterial and teeth whitening effects, but be sure not to swallow it. When rinsing your mouth, add a little baking soda. This abrasive substance can achieve the same cleaning effect as toothpaste.

6. Use a straw. Drinking coffee or wine through a straw may look weird, but doing so will reduce your teeth's exposure to tooth-staining beverages.

7. Soften the toothbrush. Using hot water to soften hard toothbrush bristles before brushing can help relieve pain on sensitive teeth.

8. Cleaning the tongue is indispensable. This reduces the effects of poor breathing habits and improves oral hygiene, as the folds of the tongue harbor a large number of bacteria. Most dental experts point out that poor oral hygiene, such as not brushing, flossing or not cleaning properly, are the main causes of gingivitis and dental caries.

9. Avoid eating sugar and starchy foods. Carbohydrates can feed the bacteria that cause dental caries. Not just desserts, but even a small piece of biscuit can feed a considerable number of bacteria. Try eating healthy snacks, such as snacks made with celery and carrots dipped in hummus or guacamole, vegetable crackers with cheese or plain yogurt, fresh fruit, and nuts.

10. Wash and floss your teeth. Regular teeth cleaning or cavities check-up may cost a small amount of money, but it can save you the high cost of dental care in the future.

Extended information:

1. Common dental problems

Brushing teeth is actually a process of removing dental plaque. Dental plaque is a soft, unmineralized bacterial population that adheres to the tooth surface and between teeth. It is the main culprit causing dental caries and periodontal disease. Plaque is firmly attached to the tooth surface, and the bacteria ingest the sugar in the saliva and break down the sugar to produce acids. These acids can destroy the teeth and eventually form holes.

When dental plaque is close to the gums, toxins and other harmful substances produced by bacteria can damage the gums and cause gingivitis. If allowed to progress, gingivitis may develop into irreversible periodontitis, causing damage to the alveolar bone and ultimately leading to loosening and loss of teeth.

2. Brush your teeth correctly

The toothbrush should be tilted 45 degrees and placed at the junction of the teeth and gums so that the bristles can contact the areas that need to be brushed. Oral medicine expert Xu Tongkai said that dental plaque is like a film stuck on the teeth, which must be wiped off with a toothbrush.

Because plaque grows in the middle and lower third of the teeth near the gums, and even grows into the gap between the teeth and gums, so only at an angle of 45 degrees can the plaque be removed Plaque is effectively removed.

The correct way to brush your teeth is to brush back and forth in a trembling manner, with small horizontal movements, no more than the width of one or two teeth, brushing one by one, from front to back, and from back to front, little by little. When brushing, the force must be controlled well, otherwise the teeth may be damaged easily if the brushing force is too large.

4. Tips for caring for your teeth

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

Replace your toothbrush every three months. Use warm water around 36°C to brush your teeth, which is similar to the temperature of your mouth. Different toothpastes are often used to brush your teeth. Food for teeth: Ingredients in some natural foods can fight against oral bacteria that cause tooth decay and strengthen tooth enamel.

Tea: The fluoride contained in tea can react with apatite nodules in teeth and has the effect of resisting acid and preventing tooth decay. Among them, oolong tea and green tea have the highest fluoride content.

The polyphenols contained in it are a complex composed of more than 30 substances, which have disinfecting and sterilizing effects, can reduce Streptococcus mutans that causes tooth decay in the oral cavity, and have the effect of solidifying teeth. Regular drinking of tea increases the fluid flow in the mouth and maintains oral hygiene.

The sugar, pectin and other ingredients in tea react chemically with saliva, moisturizing the mouth and enhancing the self-cleaning ability of the mouth. Chewing tea leaves can also treat bleeding gums.

But please note that when chewing, you should chew it carefully, grind the tea leaves into fine powder in your mouth, and then swallow it with saliva. Onions: Onions, especially fresh, raw onions, kill a variety of bacteria, including Streptococcus mutans, which is responsible for our tooth decay.

Shiitake mushrooms: The lentinan contained in shiitake mushrooms can inhibit the bacteria in the mouth from producing dental plaque. Mustard: Mustard contains ingredients that inhibit the growth of Streptococcus mutans bacteria that cause tooth decay.

Celery: Crude fiber food can sweep away part of the food residue on the teeth. In addition, strenuous chewing can secrete saliva, balance the pH value in the mouth, and achieve a natural antibacterial effect.

In addition to celery, cucumbers and carrots cut into strips can also play a role in cleaning gums. Drinking water is the simplest but most important way to protect your teeth.

Drinking an appropriate amount of water can keep our gums 100% moist and 100% powdery saliva. Drinking some water after eating can remove food particles remaining in your mouth and prevent tooth-damaging bacteria from getting nutrients.

Sugar-free gum. After chewing sugar-free chewing gum added with "xylitol", it has a significant effect on inhibiting the bacteria that cause dental caries.

Chewing with key tooth movement: Chewing regularly and regularly foods with appropriate hardness, elasticity and high fiber content, such as whole grains, miscellaneous grains, vegetables and fruits, can exercise the chewing ability of oral muscles and teeth. It makes the tooth tissue tough and strong and not easy to loosen. Chewing food thoroughly when eating can clean the gums, scrub the tooth surface, and stretch the periodontal ligament. It can accelerate blood circulation, improve local nutrition, and promote dental health.

*** Tap on the gums for 5 minutes every day, which can promote blood circulation and tissue metabolism, exercise muscles and protect the skin, promote saliva secretion and clean the mouth, and achieve the purpose of solidifying teeth and exercising periodontal function. . If your teeth are slightly loose, you can use your index finger to massage your gums for 10 minutes every morning.

You can also roll the core up and down in your mouth when chewing plums or apricots to stimulate the gums, which is of great benefit to preventing periodontitis and strengthening teeth. Teeth Habits Many people have the habit of brushing their teeth immediately after meals, thinking that this can reduce the chance of dental disease as much as possible.

However, recent research results suggest that brushing your teeth immediately after meals is harmful to dental health. This is because there is a layer of enamel on the surface of the tooth crown, and the enamel will become soft after just eating, especially after eating acidic food.

Brushing your teeth at this time will cause damage to the enamel. Therefore, it is best to rinse your mouth with water after eating and wait 1-2 hours before brushing your teeth.

5. What are some common knowledge about dental care?

Dental caries and tooth decay cannot be ignored. The most common oral disease among students is dental caries, which is tooth decay.

In fact, there are no bugs in tooth decay, but because you did not brush your teeth and rinse your mouth in time after chewing food. Under the action of bacteria, the food residue fermented, produced acid, eroded the teeth, decalcified and softened the teeth, and then Cavities slowly form, which are cavities. According to statistics, the prevalence of dental caries in children’s deciduous teeth in my country is 80% to 90%, and the prevalence in permanent teeth is 40%.

According to Dr. Han Yongcheng, director of the Beijing Dental Disease Prevention and Control Office, there are three main ways to prevent dental caries: 1. Use fluoride toothpaste. The fluoride content in domestic water in Beijing is low, so choosing fluoride toothpaste is a good supplement.

This toothpaste can make teeth stronger, acid-resistant, inhibit bacteria, and increase the ability of teeth to remineralize. After scientific verification, long-term use of fluoride toothpaste has no adverse effects on the body and is a safe method of protecting teeth.

2. Pit and fissure sealing method. This is actually the best way to prevent tooth decay.

Everyone’s back teeth (molars) always have some grooves of varying depths on the biting surface, which are pits and fissures. Pit and fissure sealing is to fill the areas prone to dental caries with polymer resin in advance to isolate external cariogenic factors.

Fissure sealing is most effective when performed within one year of the eruption of a child's molars. Dr. Han suggested that parents take their children to the preventive department of the dental hospital for pit and fissure sealing.

3. Early filling. After discovering shallow caries, you should go to the hospital for filling treatment as soon as possible.

2. Another problem that affects students’ oral health is the misalignment of teeth. This is mainly related to genetics, diet and bad living habits.

The best age for orthodontic treatment is between 12 and 14 years old. Because the deciduous teeth have been replaced by permanent teeth at this time.

Just brushing your teeth is not enough. Because brushing your teeth cleans the front half of your mouth, it is important to prevent cavities.

But after eating food, many residues remain in the back half of the mouth, pharynx, and epiglottis. Brushing teeth has no effect on the area after the base of the tongue. In addition, the lysozyme content in human saliva is reduced at night than during the day, the bactericidal ability is reduced, the blood flow becomes slower at night, and local resistance is reduced. The bacteria remaining in the oral cavity can "reproduce" and infect surrounding organs through some mutual channels in the deep oral cavity, causing pharyngitis, laryngitis and paranasal sinusitis.

So after eating snacks, in addition to brushing your teeth, you should also drink some boiled water to rinse the deep parts of your mouth. For children, the most harmful ones are thumb sucking, licking teeth, licking the upper lip, biting pencils, biting nails, mouth breathing, etc., which can cause crowding and displacement of teeth, open lips, exposed teeth, and "overwhelming" appearance; Eating sweet and greasy foods can cause tooth decay.

Adults need to master five aspects of self-oral health care in their daily lives: master the essentials of scientific tooth brushing; use fluoride appropriately; appropriately limit the consumption of sugar and sweets; conduct regular oral examinations; quit smoking Bad habits of tobacco and alcohol. Not brushing your teeth or brushing your teeth improperly can cause periodontitis and periodontal atrophy; tobacco and bad eating habits such as strong alcohol, hot and spicy food, and eating too fast can cause oral mucosal leukoplakia, mucosal blood blisters, and oral cancer; brush your teeth horizontally It can cause wedge-shaped defects of teeth; unilateral chewing can cause temporomandibular joint disease and brushing the front teeth alone is not enough.

6. 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 the age of 7 to 12, 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 is visible 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 tooth root surface 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 and enter 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? ⑼昀锩嬖 snuggle⑼饷妗2袢山嵯蚶椿赜蜜％? 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.
