mustard
Tasting sashimi or holding sushi in Japanese cuisine should be accompanied by mustard that makes people cry and runny nose. The main purpose is sterilization. Mustard produces such a pungent and choking smell because it contains an ingredient called isothiocyanate, which is also found in other cruciferous vegetables. In vitro experiments in Japan, it was found that isothiocyanate in mustard can inhibit the reproduction of Streptococcus mutans, which causes tooth decay. How to eat? Besides serving with sashimi, you can also mix a spoonful of mustard with a little soy sauce as a dipping sauce for boiled seafood. Or mix mustard, honey and water in equal proportion and pour them on cuttlefish and shrimp to make cold sauce, which can neutralize the fishy smell of seafood.
Rice, lentils, peas and broad beans
These foods are rich in phosphorus. Phosphate can form a buffer system to prevent excessive acidification of the mouth, so it has the effect of protecting teeth.
Marine fish, tea and mineral water
These foods contain fluorine. Fluorine can combine with hydroxyapatite in dentin to form fluoride-containing hydroxyapatite, which can enhance the resistance of decalcification of enamel, thus playing a role in preventing caries. In addition, fluoride can also inhibit the growth of bacteria by inhibiting enzymes in bacteria.
sugarless chewing gum
Chewing sugar-free gum can increase saliva secretion, neutralize acidic substances in the mouth and further prevent tooth decay. A study by the School of Dentistry of the University of Minnesota in the United States found that chewing sugar-free chewing gum with "xylitol" has obvious effect on inhibiting bacteria causing dental caries. Xylitol is a low-calorie sugar substitute, which can produce sweetness, but it will not be used by bacteria in the mouth. How to eat?

Pharmacological research shows that Lycium barbarum can promote the proliferation and adhesion of periodontal ligament or fibroblasts.
jujube
As the saying goes, "teeth benefit the spleen, dates benefit the spleen and lose teeth." Recently, it was reported abroad that Japanese researchers screened 74 kinds of traditional Chinese medicines in order to find out the traditional Chinese medicines to prevent tooth decay. Therefore, ursolic acid and oleanolic acid were extracted and separated from jujube. These two components can control the enzymes produced by dental caries without destroying the bacterial balance of oral bacteria.
celery

Cheese is not only a good source of calcium, but also has other protective effects on teeth. British research pointed out that the calcium and phosphate contained in cheese can balance the pH value in the mouth and prevent the mouth from being in an acidic environment conducive to bacterial activities, leading to tooth decay; Moreover, regular consumption of cheese can increase the calcium on the surface of teeth, which helps to strengthen and rebuild enamel (because calcium is the most important component of enamel) and make teeth stronger. How to eat? Have a tomato and cheese sandwich for breakfast and prepare 2 slices of whole wheat toast, 1 slice of tomato about 3 cm thick, 1 slice of low-fat cheese. Put the cheese slices on the toast first, and then put the dried tomatoes; According to personal taste, squeeze a little yellow mustard sauce and sprinkle a little black pepper; Then clip the materials together with another piece of toast. Wrap the whole toast with tin foil, put it in a preheated oven and bake it for 8 ~ 10 minutes.
onion
The sulfur-containing compound in onion is a powerful antibacterial component. In the test tube experiment, it was found that onion can kill many kinds of bacteria, including Streptococcus mutans, which causes tooth decay, and fresh raw onion has the best effect. How to eat? It is suggested to eat half a raw onion every day, which can not only prevent tooth decay, but also help to lower cholesterol, prevent heart disease and enhance immunity.

Six ways to whiten teeth
Have a cup of Tieguanyin after dinner.
Good teeth are inseparable from fluoride. Tieguanyin is rich in fluoride, about 40%-80% of which is dissolved in boiling water, which is easy to combine with calcium in teeth and form a layer of calcium fluoride on the surface of teeth, which plays a role in preventing acid and caries.
Change a toothpaste every month.
Don't use a toothpaste for a long time, the brand and model can be changed every month. Moreover, the longer the toothpaste is used, the higher the chance of contact with bacteria, so it is best to choose a month's dosage when buying toothpaste.
Wash your teeth every six months.
Tobacco and alcohol corrode teeth and deposit a lot of dental plaque, melanin and tartar on the surface of teeth. Dental experts have found that men are more likely to suffer from periodontal disease because of drinking, smoking and improper diet. It is suggested that teeth should be washed once every six months to one year according to the growth rate of dental calculus. Usually, we should also monitor the dental condition and find problems early.
Eat more Vc tooth protection food.
If you lack vitamin C, periodontal disease may occur, so you must eat tooth protection food rich in vitamin C every day. Vegetables, oranges and lemons all contain a variety of trace elements and are rich in vitamin C, which is unacceptable for protecting teeth. If necessary, you can take vitamin C tablets to supplement.
Drinking straw
Drinking soda through straws is no longer a woman's patent. We should reduce the time that soda stays in our mouth, because time is a very important factor in the process of tooth decay. The shorter the contact time between oral bacteria and fermentable carbohydrates, the less likely the bacteria will produce acid. Not only sweet drinks, but also unsweetened soft drinks and sports drinks do much more harm to tooth glaze than coke, which are three times and 1 1 times respectively.
Brush your teeth with warm water
Before brushing teeth, soak the toothbrush head with toothpaste in warm water at about 35℃ 1-3 minutes. This can make the bristles soft and elastic, and reduce the friction loss of the bristles to the teeth and the irritation damage to the gums.
