Teeth are small details, but if we don't pay attention to the beauty of these details, our image will be seriously compromised.

Therefore, we must pay attention to the cleaning and care of teeth. We can start from the following aspects: daily cleaning and nursing 1.

Brush your teeth often. Many people usually brush their teeth only after getting up in the morning, but this is not enough to keep their teeth clean.

Besides in the morning, you need to wash after three meals and before going to bed at night. 2。

The method of brushing teeth should be correct. Many people often use the method of pulling the toothbrush left and right when brushing their teeth. This method is difficult to completely remove the residue between teeth, and it will also cause some wear and tear to the places with more stress.

The correct way to brush your teeth is to swing your toothbrush up and down and clean the inside of your teeth. 3。

Smoke less and drink less coffee and tea. People who are heavy smokers and like to drink coffee and tea often have cigarette burns and tea stains on their teeth, which will turn yellow easily over time and release an unpleasant smell when they open their mouths.

In view of this, if you want to keep your teeth clean, you must smoke less and drink less coffee and tea. 4。

Wash your teeth regularly. Tooth washing can completely remove the tartar attached to the teeth, so we'd better go to the stomatological hospital to wash our teeth once or twice a year.

After a full meal, many people will habitually pick up toothpicks and pick their teeth between their teeth, looking carefree. But in fact, improper tooth picking methods can easily lead to many dental problems, such as bigger and bigger teeth, inflamed gums, swelling and pain, etc.

In this regard, for those who like to pick their teeth, we make some suggestions: 1. Use sterilized toothpicks.

Unserified toothpicks are often accompanied by a large number of bacteria and viruses. When people pick their teeth, these bacteria and viruses will enter the mouth, causing gum inflammation. According to the investigation of Consumers Association, toothpicks in the catering market are mostly "three-no products", and the disinfection and cleaning of toothpicks can not meet the hygiene standards. In addition, toothpicks are placed in the dining environment where people come and go for a long time, which further increases the carrying capacity of germs on toothpicks, thus posing a great threat to human health.

Therefore, people who like to pick their teeth must choose to use those sterilized clean toothpicks. 2。

Don't use too much force when picking your teeth. Excessive tooth picking will puncture fragile gums, leading to gingivitis, gingival atrophy and other diseases.

Some people pick their teeth with toothpicks when there is no gap between their teeth, and even press the toothpicks hard in the * * * area between people's teeth, which will not only make people feel uncomfortable, but also enlarge the gap between teeth without gaps and affect the beauty of teeth. 3。

Choose a cleaning method that can replace tooth picking. Rinsing your mouth or brushing your teeth after meals is a good way to clean your mouth. This method can not only clean the food residue in the mouth, but also refresh the breath. Compared with the method of picking teeth after meals, it is both beautiful and hygienic.

Although there are many ways to clean teeth, the most important thing is long-term persistence and perseverance. Only in this way, annoying dental problems will not make our smiles discount and make our image more sunny.

2. What are the tips for dental care?

Every morning before I wake up and go to bed, I insist on tapping each other with my upper and lower teeth. At first I knocked a dozen times, and then I will increase the number and intensity of knocking day by day, reaching about 50 times each time.

After a night's rest, when people get up in the morning, the periodontal tissue is still loose and the teeth are a little loose. If you pat your teeth gently at this time, you can consolidate the root and periodontal tissue, and make the nerves, blood vessels and dental pulp cells active, which is very beneficial to protect your teeth.

Bite your teeth hard every time you pee. It happens every time you drown. Rinse your mouth with tea after each meal, let the tea flow repeatedly in your mouth, and clean your teeth and tongue.

Be sure to close your mouth, bulge your cheeks and rinse your mouth once or twice every day, and turn your tongue left and right at the same time. This method can increase the secretion of oral saliva, so that the surface of teeth, crevices and oral mucosa can be cleaned to a certain extent, thus increasing the self-cleaning effect of oral cavity and improving the disease resistance of teeth.

Follow the gums with the cleaned thumb and forefinger in a certain order, every time 10 minute, 2-3 times a day. Gently close your mouth and lips, breathe through your nose, roll up your tongue, and push the upper jaw one by one.

Eating coarse grains rich in cellulose, chewing slowly, and brushing your teeth alone can't completely remove foreign bodies. After the teeth are thoroughly cleaned, new dental plaque will form within half an hour, reaching the maximum within 30 days. Over time, it will become calculus, which will cause gingivitis, periodontitis, bleeding, bad breath, and finally lead to tooth loosening or even falling off.

Therefore, if adults have not cleaned their teeth, they should go to the hospital as soon as possible to have their teeth cleaned, preferably once every six months. The habit of chewing with one tooth is not good. If you often chew food with one tooth, the commonly used tooth will be overburdened, and the tooth will wear easily, causing dentin hypersensitivity or gingivitis.

Due to the lack of proper food friction, abnormal teeth have weak periodontal tissue, which is easy to accumulate tartar, causing dental caries and periodontal disease, making one side of the facial muscles more developed than the other, resulting in asymmetry on both sides of the face, thus affecting the appearance.

3. How to care for the teeth of the elderly?

When we face the problem of aging, we should not disbelieve in science and admit that we are old. Our teeth fall off easily, which will have a serious impact on our future diet. Therefore, you must brush your teeth in the morning and evening. In the process of brushing teeth, it is necessary to clean up the residue between teeth, dental plaque and yellow pigment on teeth to prevent tartar from accumulating on gums and prevent teeth from aging.

In addition, you can do more small-scale exercise, such as walking and micro-stretching. Only in good health can we delay the atrophy of periodontal tissue, improve the resistance of teeth and make teeth stronger.

At the same time, don't eat chicken, pig and other ribs in daily life to avoid hurting your teeth. Also, you must remember to rinse your mouth after meals, and you can use warm tea, so that you can remove food residues in the gaps between your teeth in time and avoid the interference and breeding of bacteria.

You can chew some sugar-free chewing gum when you are free, which can increase the elasticity of masseter muscle and the toughness of tissues around gums and make teeth stronger.

4. Knowledge of dental care

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 pair is deciduous teeth, the upper and lower jaws have 20 teeth, and 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, with 32 teeth in the upper jaw and 65,438+06 teeth in the lower jaw. The deciduous teeth gradually change from the age of 6, and all the permanent teeth erupt around the age of 12 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.

5. What are the methods of dental care?

Dental plaque is formed on the surface of teeth and is almost invisible to the naked eye, which is the chief culprit of gum disease.

To remove dental plaque, brush your teeth for 5 minutes at a time, at least once a day. You should use nylon toothbrush with moderate hardness and fluoride toothpaste, and pay special attention to cleaning teeth and gum line.

The specific steps are as follows: rotate the toothbrush at an angle of 45 degrees between the bristles and the gums, and clean the front teeth for about 30 seconds. Even if you brush your teeth often, you can't remove the plaque between your teeth and gums. You can floss every day.

Hold the bristles at a 45-degree angle against the gum line, rotate the toothbrush and brush the outside of the upper and lower teeth. When brushing the inside of teeth, each toothbrush has a small circle for about 30 seconds.

When brushing the occlusal surface of teeth, brush it back and forth steadily. Brush the occlusal surface of teeth in the same way.

The front teeth should be brushed up and down, but it is more convenient to put the toothbrush head vertically and obliquely.
