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

First, pick your teeth.

In the process of chewing food, dietary fiber (such as leek, celery, lean meat, etc. ) it is often stuck in the teeth, which is harmful to teeth and periodontal tissue. It should be pulled out in time, but be careful not to pick your teeth too frequently, so your teeth may be elongated.

Second, knock your teeth often.

Since ancient times, people who are good at keeping in good health have emphasized that "teeth should be knocked often." Clearly, the diet is not advanced, and the teeth and gums are not filled. Tapping the teeth gently can promote the smooth blood vessels and protect the teeth. "It's obvious that thirty-six pieces have been smashed, but the old teeth won't fall out." The method is to "slightly close your lips, first knock your teeth 50 times, then knock your teeth 50 times, and then knock your wrong teeth 50 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 or both sides.

Fourth, correct bad habits.

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

5. Drink tea often.

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

6. Take certain drugs with caution.

Tetracycline, gold toxin and other drugs will make teeth yellow or enamel hypoplasia, and dental caries will easily occur in the future. Therefore, pregnant women and lactating women and babies should not take these drugs in large quantities or for a long time.

Seven, a wide range of recipes and good nutrition.

The development of teeth is inseparable from various nutritious foods. Therefore, regardless of adults and children, the diet should be diversified and not partial eclipse.

Eight, protect your teeth.

The kidney dominates the bone and the tooth is the bone. With sufficient kidney essence, teeth will develop politically and grow firmly. Therefore, tonifying kidney and storing essence is also a means of self-care of teeth.

Nine, prevent trauma.

Don't use your teeth to open hard objects such as bottle caps to prevent your teeth from being damaged.

2. Love your teeth.

Alcohol is the enemy of fresh breath, so try to avoid drinking alcohol or using alcoholic mouthwash. Clean your teeth regularly:

Tooth washing is to remove the tartar hidden around the tooth flesh and the stains on the tooth surface, such as tea stains, coffee stains, cigarette stains and so on. However, it should be noted that some stains cannot be removed, such as stains that go deep into the teeth. Habitual flossing:

When tooth flesh is red, swollen and inflamed, it is easy to cause bleeding during tooth washing or brushing. Please don't worry, if you can use dental floss and electric toothbrush correctly and take effective brushing methods, tooth inflammation and bleeding can be improved. Master the correct method of brushing teeth:

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

Gargling can remove food debris and some soft dirt, keep the mouth clean and give full play to its physiological functions. Chew fully:

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

Knock your teeth ten times every morning to enhance the resistance of your teeth and periodontal tissue. * * * Gums:

After brushing your teeth in the morning and evening, gently press your cleaned fingers on your gums for a few minutes. Eat less sulfur-containing food:

Through scientific research, it is found that dairy products, onions, garlic and other foods containing a lot of sulfur are prone to produce anaerobic bacteria that cause bad breath. Chewing gum should be xylitol;

In fact, sugary chewing gum is more likely to cause tooth decay or bad breath. Therefore, choosing chewing gum containing xylitol can effectively strengthen teeth and ensure fresh breath. Fresh breath, not "aggressive", is also necessary for your interpersonal public relations.

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

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

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

Until 12~ 13 years old, all deciduous teeth fell off and permanent teeth were replaced. After that, the single permanent tooth: 12~ 14 years old, the second molar grows behind the first molar, and the third molar grows after 18 years old.

It is normal for some people not to have a third molar. Problems to pay attention to when changing teeth: deciduous teeth should be lost but not lost. Doctors call this phenomenon retention of deciduous teeth, so they should take their children to the hospital for examination and treatment in time.

The main reasons are: dislocation of permanent teeth embryo, absence of permanent teeth embryo, and retained teeth with eruption of permanent teeth but without eruption of deciduous teeth should be pulled out as soon as possible, so as not to affect the eruption of permanent teeth in normal position. Don't pull out the primary teeth after the age of tooth replacement and the permanent teeth before they erupt. If permanent teeth are congenital missing, try to keep deciduous teeth.

Early deciduous teeth fall off: deciduous teeth fall off before they should, which is called early deciduous teeth fall off. It often causes the adjacent teeth on both sides to tilt towards the gap of missing teeth, which makes the gap of missing teeth smaller, and the permanent teeth sprout out of position due to insufficient gap.

Wear a gap fixer at the gap between deciduous teeth to prevent the teeth on both sides from tilting until the permanent teeth erupt. Difficult eruption of permanent teeth: permanent teeth produce eruption force during root development, which makes permanent teeth move to gum side and gradually erupt. This requires a process, especially the upper teeth.

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

Some malocclusion deformities can't be adjusted by themselves, which will affect facial development. They should go to the hospital for treatment. Double-layer teeth: It is not uncommon for permanent teeth to come out before deciduous teeth fall off. This may be because the root of deciduous teeth is not completely absorbed.

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

If the pain is severe, 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 does not replace any deciduous teeth, and it is easy to mistake them for deciduous teeth. Clinically, many children have dental caries at the age of six, which have developed into pulpitis or periapical periodontitis.

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

When the child reaches the age of 10, the front teeth and back molars have erupted. Parents can add some celery stalks, corn, apples and other foods, so that tooth replacement can be completed smoothly and children can have a healthy and tidy permanent tooth. Prevention of inferiority complex during tooth replacement Children's self-esteem has been established during tooth replacement. I care if the front teeth look good.

If you joke about this, children will feel inferior and even lick their teeth desperately, hoping to grow up quickly, but the result is counterproductive. You can tell children that white swans are all made by ugly ducklings. The front teeth fall off and look ugly. This is a transformation process, which proves that "you are about to grow up", and every child has to go through this process when growing up.

4. Love your 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 oral temperature. Brush your teeth with different toothpaste.

Key tooth food

Some ingredients in natural food can fight against oral bacteria that cause tooth decay and strengthen tooth enamel.

Tea: Fluorine contained in tea can be combined with apatite tuberculosis in teeth, which has the functions of acid resistance and tooth decay prevention. Among them, oolong tea and green tea have the highest fluorine content. Polyphenol contained in it is a complex composed of more than 30 substances, which has the efficacy of disinfection and sterilization, can reduce Streptococcus mutans causing tooth decay in the oral cavity, and has the effect of strengthening teeth. Drinking tea regularly can increase the flow of water and liquid in the mouth and maintain oral hygiene. Sugar, pectin and other ingredients in tea react with saliva to moisten the mouth and enhance the self-cleaning ability of the mouth. Chewing tea can also cure gum bleeding. However, it should be noted that when chewing, you should chew slowly and let the tea be ground and chewed into fine powder in your mouth before swallowing saliva.

Onion: Onion, especially fresh raw onion, can kill many kinds of bacteria, including Streptococcus mutans, which causes our tooth decay.

Lentinus edodes: Lentinus edodes contains lentinan, which can inhibit bacteria in oral cavity from producing dental plaque.

Mustard: Mustard contains some ingredients, which can inhibit the reproduction of Streptococcus mutans and lead to tooth decay.

Celery: Crude fiber food can sweep some food residues from teeth. In addition, hard chewing can secrete saliva, balance the pH in the mouth, and achieve natural antibacterial effect. Besides celery, sliced cucumbers and carrots can also function as gums.

Drinking water is the simplest but most important way to protect teeth. Drinking water in moderation can make our gums moist and drool. Drinking some water after a meal can take away the food residue in the residual mouth and prevent the bacteria that damage the teeth from getting nutrition.

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

Key-tooth motion

Chewing: Chewing foods with appropriate hardness, elasticity and high cellulose content, such as coarse grains, miscellaneous grains, vegetables, fruits, etc., can exercise the chewing ability of oral muscles and teeth, and make the tooth tissue 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 tooth health.

* * * Gums

Sticking teeth for 5 minutes every day can promote blood circulation and tissue metabolism, exercise muscles and protect skin, promote saliva secretion and clean mouth, and achieve the purpose of strengthening teeth and exercising periodontal function. If the teeth are slightly loose, you can use your index finger * * * gum 10 minute every morning. You can also roll the nucleus up and down in your mouth when talking about plums or apricots, which is of great benefit to prevent periodontitis and strengthen your teeth.

Key dental habits

Many people have the habit of brushing their teeth immediately after meals, thinking that this can minimize the chance of dental diseases. 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, which will soften after eating, especially after eating acidic food. Brushing your teeth at this time will cause enamel damage. Therefore, it is best to rinse your mouth with clean water after meals, and brush your teeth after 1-2 hours.

5. What are the common knowledge of oral hygiene among primary school students?

Harm of dental caries

1, which 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 after tooth replacement;

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

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

5, affect the appearance and pronunciation: teeth, vocal cords and tongue together constitute the human body's pronunciation system. The premature tooth loss caused by dental caries will affect the correct pronunciation and speech, and the decay and loss of dentition will also affect the appearance.

How to prevent tooth decay

Even if bacteria break down food in the mouth to form acidic substances, it will take some time for acidic substances to act on teeth to break down enamel and form tooth decay. 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 meals. Plaque is most likely to form at night, so brushing your teeth before going to bed is particularly important.

Oral hygiene knowledge 3: changing teeth

The order of deciduous teeth falling off

1, central incisor -6-7 years old

2, lateral incisors-7-8 years old

3, fangs-10- 12 years old

4. First deciduous molar -9- 1 1 year

5. The second deciduous molar-10- 12 years old.

Matters needing attention during tooth replacement

1, pay attention to whether the deciduous teeth stay: deciduous teeth fall off in a certain time and order, and should fall off instead of falling off. 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 the eruption of permanent teeth is difficult: deciduous teeth fall off prematurely, children are used to chewing with gums, gums will become thick and tough, hindering the eruption of permanent teeth. Calcium deficiency in children is also an important reason for delayed eruption of permanent teeth. Therefore, if the child has reached the age of changing teeth and the permanent teeth have not yet grown out, it is necessary to take the child to the hospital for examination in time.

3, pay attention to the child's oral hygiene: during the tooth replacement period, deciduous teeth and permanent teeth coexist, permanent teeth just erupted, and there are many pits on the occlusal surface, which is easy to leave food residue. In addition, children don't like to brush their teeth, they like sweets, and their teeth often decay. 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: in the tooth changing period, when the deciduous teeth are loose and about to fall off, children are often used to licking loose teeth with their tongues. This is a bad habit, which will affect the normal eruption of permanent teeth and cause dislocation occlusion-that is, the teeth are not arranged neatly. Parents should correct it in time.

5. Correction of malocclusion: Some malocclusions are due to pathological reasons. For example, the labial frenum position of the upper lip is too low, and the gap between the upper teeth is too large to adjust 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 teeth, we must first understand the structure of 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 a deciduous tooth with 20 teeth, and the upper and lower jaws have 10 teeth. It began to erupt about half a year after birth and came out about two and a half years old. From 7 years old to 12, deciduous teeth fall off one after another. The other pair is permanent teeth, 32 in total, with maxillary and mandibular 16. From the age of 6, the deciduous teeth gradually change, 12 years old, and all the permanent teeth erupt except the third molar.

The third molar usually erupts after the age of 20, also called wisdom tooth. Wisdom teeth will never come out, so 28~32 permanent teeth are normal.

Teeth are divided into three parts: crown, neck and root. The crown is the part we can see, and it is the part where the teeth are exposed outside the gums.

The surface of the crown is covered with a layer of enamel, which is the hardest tissue in the human body, and its hardness is similar to that of the time. The root is embedded in the alveolar process of the upper and lower jaws.

The root surface is covered with a layer of cementum. The neck of the tooth is a slightly thinner part between the crown and the root of the tooth, which wraps the gum.

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

Blood vessels and nerves enter and exit from the apical foramen of teeth. When suffering from dental caries, bacteria corrode enamel and dentin and enter the pulp cavity, which is unbearable.

(See Figure 37) Students should do the following to protect their teeth: 1. Develop a good habit of brushing your teeth. 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, it will damage your teeth, and don't brush your teeth for too long. Pay attention to the correct brushing method: brush vertically along the teeth, first brush the inside and then brush the outside.

Don't brush back and forth horizontally, or you will damage your gums. 2. Pay attention to oral hygiene and protect your teeth.

Eat less candy at ordinary times. Especially don't eat sugar before going to bed to prevent dental caries.

In addition, we should pay attention to the usual hygiene habits, do not bite fingers, do not bite pencils and other foreign bodies, and do not lick your teeth with your tongue. 3. If your teeth are sick, you should seek medical advice in time.

If there are cavities, they should be repaired or pulled out. It is not difficult to achieve the above points, the key is perseverance.

May all students have healthy and beautiful teeth. Good oral health care is not the only way to have healthy and beautiful teeth.

Eating habits also play an important role. Here are some suggestions to help you have a beautiful smile! Your teeth: the main symbol of health and beauty. Teeth enable us to enjoy all kinds of food! Healthy teeth can make us chew hard food, meat, raw food and fruit without scruple ... Good chewing can strengthen the strength of gums and promote saliva secretion. They participate in the digestive process and play a bactericidal role in teeth.

In addition to genetic factors, the color and hardness of our teeth also depend on dental care and eating habits. Keep your teeth healthy: a balanced diet! A balanced diet and proper dietary distribution throughout the day (in order to avoid snacks, four meals a day: breakfast, lunch, dinner and snacks) are very beneficial to strong teeth.

In fact, it helps our teeth to better resist * * *: enamel erosion, dental caries ... Fresh food, such as carrots, carrots or apples, rubs on the surface of teeth when chewing, which actually plays a role in cleaning teeth. In addition, lipids, some protein (casein of cheese), minerals (phosphorus, calcium, fluorine ...) and vitamin D have antibacterial effects, which limit the discharge of inorganic salts in enamel.

On the contrary, snacks, especially those "soft" foods, carbohydrate foods (candy or sweet drinks, bread, cakes, etc. ) or acidic foods (soda, fruit, juice) usually increase the risk of dental caries. Sugar can be converted into acid, which may destroy the enamel on the tooth surface.

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

In fact, any increase in saliva flow will reduce the risk of dental caries. It should be pointed out that excessive drinking of coffee, tea and smoking may make teeth yellow.

Four dairy products make teeth stronger. They are the best sources of calcium and phosphorus we need, and the main minerals of tooth enamel and root supporting bone. Mineralization of deciduous teeth began in the fourth month of pregnancy, and mineralization of stone teeth began in the first year of birth.

After the teeth are formed, the enamel is renewed and maintained. We should drink milk, and it is better not to drink sweet drinks.

Dairy products (yogurt, etc. ) Also bring calcium, phosphorus and vitamin D, which will increase the absorption of calcium and phosphorus. Finally, the main protein casein in milk can limit the excessive discharge of inorganic salts in enamel.

People in the past did a good job: they usually ate cheese after dessert and reduced the acid secreted by carbohydrates with the help of casein and lipids in milk. Drink more mineral water, which is a natural source of fluorine. Natural mineral water meets the human body's demand for fluorine.

Fluorine can increase the enamel of teeth, strengthen teeth and protect teeth from microbial erosion. Most mineral water contains 0.3 mg of fluorine per liter, but some are as high as 8 mg per liter.

We can also see fluoride on the dining table. For pregnant women and children, there are also tablets made of fluorine (0.5 mg to 1 mg according to age).

Tea, sea fish and some vegetables (spinach, carrots, etc.) also contain fluorine. However, excessive intake of fluoride (more than 2 mg per day) may make teeth black.

Take advantage of chocolate and sugar-free chewing gum. In fact, cocoa contains tannic acid, fluorine and calcium phosphate. All three substances are involved in protecting teeth.

In "sugar-free" chewing gum, sucrose is replaced by sweet polyol, but it will not cause dental caries: xylitol plays a bactericidal role, which is beneficial to reducing dental plaque, and sorbitol (sugar synthesized from glucose or fructose, used as artificial sweet flavoring agent). So a 2.2g sugar-coated chewing gum has only 3.8 calories.
