Your teeth: the main sign 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 stimulation: 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 also 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.
Use 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.
