Can bananas whiten teeth? What can you eat to make your teeth white?
A cup of tea or coffee every day is a small enjoyment for many people's busy lives. However, I am worried that the pigmentation of teeth will turn yellow, and I always feel embarrassed to show my teeth. Another study abroad pointed out that the condition of their teeth will make their appearance look old! However, if the toothbrush is excessively cleaned, it will cause enamel damage and gingival atrophy, which will damage the teeth instead of whitening them. In fact, bananas, pineapples and other fruits and baking soda that are common in daily life can make teeth white and bright!

banana

The natural tooth whitening method introduced by Japanese beauty and health columnist Morita Meng has caused extensive discussion on the Internet. This method has been certified by American dentists, and many American netizens uploaded experimental videos to youtube.

Practice: smear your teeth with the inside of banana peel 1 minute, about 10 minute (try to keep your teeth in contact with the air while waiting, don't shut up), and then brush your teeth with a dry toothbrush.

The dirt on the tooth surface comes from the tannin of coffee and green tea, and the pigment precipitation caused by chocolate, curry and other foods. There are minerals such as magnesium and potassium on the inside of banana peel, which can whiten teeth. Potassium can adsorb dirt on teeth and make teeth white.

In addition to pigmentation, tooth brushing too hard causes enamel damage, which is also one of the reasons for yellow teeth. Bananas contain natural whitening ingredients, which are not only helpful for yellowing caused by tooth enamel loss, but also non-abrasive. Vitamin D in bananas can strengthen teeth and help minerals penetrate teeth.

Malic acid and baking soda

Irving Zinger, a cosmetic dentist of the American Aesthetic Dentistry Association, pointed out that malic acid in fruits, such as oranges, strawberries and pineapples, can remove dirt from teeth.

Practice: You can squeeze the fruit into juice (a strawberry), add a spoonful of baking soda powder, make it into a sticky paste and apply it to your teeth. Let it stand for five minutes, then rinse your mouth and clean it with a toothbrush.

Because this method may cause enamel damage, it is limited to once a week. Baking soda powder itself has a cleaning effect. You can also add 3 grams of baking soda powder (about 10 times) to 500ML of water, rinse your mouth for 30 seconds and then spit it out.

coconut oil

The rich medium-chain fatty acids in coconut oil have antibacterial and anti-inflammatory effects, which can not only whiten teeth, but also prevent tooth decay and improve gingivitis.

Practice: put a spoonful of coconut oil in your mouth, rinse your mouth slightly, spit it out after about 15 to 20 minutes, and then brush your teeth daily.

Coconut oil can remove oil stains and calculus from teeth. Microbial cells in the oral cavity are usually covered with lipids or fats, and lipids are incompatible with water. Compared with rinsing with clean water, oil stains can combine with lipids, adsorb bacteria between teeth and oral gums, and keep the oral environment healthy.
