First, fast tooth food recommendation
1, strawberry
Strawberry is a natural tooth whitening fruit, which can not only make teeth stronger, but also contain some ingredients that can bleach and clean teeth and remove stains on the surface of teeth. Mixed with baking powder, it becomes a natural tooth cleaner, which can remove the stains left on the tooth surface by coffee, red wine and cola. Although the effect of strawberry whitening teeth is not as good as that of cold light whitening, it still has certain effect. So eat some strawberries after meals and your teeth will be healthy and beautiful.
2. Cauliflower
Unlike beets and cranberries, this crisp vegetable will not remain on the surface of teeth, so it will not form ugly stains. This cruciferous vegetable can also be used as a "scrub" to whiten teeth and clean tooth surfaces, which is equivalent to simple and natural care for oral hygiene. At the same time, cauliflower can stimulate the production of saliva and help prevent the formation of dental plaque. Therefore, if you want to clean your teeth, remember to eat more broccoli.
3. Apple
Apple is a fruit rich in fiber and needs more time to chew. In the process of chewing, you will secrete a lot of saliva, which is the best protector of teeth. It can clean and strengthen teeth, prevent tooth decay and prevent bacteria from adhering to teeth, thus making it easier to keep teeth clean for a long time. Some studies have also found that saliva contains a lot of mineral elements, which can repair early tooth decay. In addition, apples can also reduce the body's absorption of sugar.
4.celery
Celery is a crude fiber food, which can whiten teeth well. When you chew celery, it is giving your teeth a general cleaning, which will reduce your chances of tooth decay. Because these crude fiber foods are like brooms, they can sweep away some food residues and bacteria that grow on the surface of teeth. On the other hand, the harder you chew, the more you can stimulate saliva secretion, balance the pH in the mouth, and achieve natural antibacterial effect.
5. Onions, ginger and garlic
Many people may think that tooth whitening is really embarrassing, but although eating onions, ginger and garlic will not taste very good, these foods contain rich and powerful bactericidal substances, which help to whiten teeth. For example, eating raw onions or garlic can effectively kill Streptococcus mutans, which is the bacteria that causes tooth decay. In addition, mustard and other foods also have the function of sterilization and tooth protection.
6. Yogurt and cheese
As we all know, insufficient calcium intake will shake bones, in fact, it will also wear away the health of teeth, so we should supplement calcium from various natural foods every day. Dairy products such as yogurt and cheese are not only one of the good sources of calcium, but also have other protective effects on teeth. The rich trace elements such as calcium and phosphorus in dairy products help to balance the pH value of the oral cavity and avoid the oral cavity being in an acidic environment all the time, thus improving the health of enamel. Eating dairy products regularly can increase calcium on the surface of teeth, strengthen and rebuild enamel, and clean and strengthen teeth. Besides whitening teeth, the most important thing is of course to ensure the health of teeth!
7.guava
Chewing guava is another good way to whiten teeth and keep gums healthy. Guava is low in calories, so many people use it to increase satiety when dieting, and its vitamin C content is the highest among fruits. Vitamin C is an important nutrient to maintain healthy gums. People who are seriously deficient will become fragile, prone to illness, and have symptoms such as swollen gums, bleeding, loose teeth or falling off.
8.nuts
Nuts have a crunchy taste. Chewing this rough and hard food can play a grinding role and help to wipe off plaque stains and substances that cause tooth coloring.
It is recommended to eat almonds with meals every afternoon. It is not only rich in protein and healthy fat, but also can make your teeth as white as pearls by chewing.
9. Green tea
Drinking green tea can make teeth healthier. On the one hand, because green tea contains a lot of fluorine (as do other teas), it can combine with apatite in teeth and has the functions of acid resistance and tooth decay prevention. On the other hand, studies have shown that catechins in green tea can reduce Streptococcus mutans, which causes oral cavity decay, and can also remove unpleasant breath.
Drink 2 ~ 5 cups of green tea every day according to personal preference. It is recommended to drink after meals or desserts. In addition, green tea contains caffeine, so pregnant women should limit their drinking.
10, carrot
Lack of vitamin A can lead to periodontal disease. This is because vitamin A can enhance the resistance of enamel and the vitality of epithelial cells in periodontal tissue. Carotene is the "treasure house" of vitamin A. Eating three carrots or radishes every week can keep the normal level of vitamin A in the body.
In addition, eating raw carrots can play a role in brushing your teeth. It not only helps to remove food residues in the mouth, but also stimulates saliva secretion, so that the mouth can be naturally cleaned.
1 1, spinach
Fresh spinach contains 99% water, which can dilute the sugar in the mouth, make it difficult for bacteria to grow and prevent dental caries.
In addition, spinach belongs to dark green leafy vegetables and contains a series of minerals such as magnesium, which is helpful to the formation of anti-fouling film on tooth surface and plays an important role in keeping enamel white.

Eating these vegetables often can increase the content of molybdenum in teeth, enhance the firmness of teeth, and promote the development of mandible and the neatness of teeth.
13, watermelon juice
It can supplement 25% of vitamin C needed by human body every day. Vitamin C is very important for the health of teeth and gums. It contributes to the absorption of iron, and also has antioxidant effect to prevent tooth aging caused by the oxidation of "free radical" molecules. And vitamin C is also a key point of whitening.
14, orange
Vitamin C in oranges can also promote the health of teeth and gums, and the fiber in oranges can also make dental plaque fall off.

The key to tooth whitening is to pay attention to personal oral hygiene, keep it clean and brush your teeth in the morning and evening. Some people brush their teeth for less than a minute and can't clean the bacteria in their mouths at all. The brushing time is kept at about 2 minutes.
