A share from Haimei: a cup of tea or coffee every day is a relaxing choice for many busy urbanites after work. However, colored drinks will deposit pigment on the teeth, making the teeth look yellow and affecting the appearance. A foreign study has pointed out that yellowing teeth can make people look older than four years old. However, if you use toothbrush to clean excessively, it will cause enamel damage, gingival atrophy, and teeth whitening will be damaged instead. But did you know that the common fruits in daily life, such as bananas and apples, mixed with baking soda powder, can make your teeth white and bright!
Whitening teeth with banana peel
The natural tooth whitening method introduced by Morita Meng, a Japanese beauty and health columnist, has been widely discussed on the Internet. After the certification of American dentists and the personal experiments of many American netizens, it is proved that banana has a significant effect on tooth whitening. The stain on the surface of teeth comes from the pigmentation of coffee, green tea, chocolate and curry. The inside of banana skin has magnesium and potassium, which can whiten teeth. Potassium can absorb the dirt of teeth and make teeth white. In addition to pigment precipitation, excessive force when brushing teeth causes enamel damage, which is also one of the reasons for teeth yellowing. Banana contains natural whitening ingredients, which not only helps to yellowing caused by tooth enamel loss, but also has no abrasiveness. Instead, vitamin D in bananas strengthens teeth and helps minerals penetrate into them.
Specific measures: use the inside of banana peel to smear teeth for 1 minute, and then wait about 10 minutes. In the process of waiting, try to let the teeth contact the air, do not close your mouth! Finally, brush your teeth with a dry toothbrush.

However, frequent use of baking soda can damage tooth enamel, so it is recommended to use it once a week.
Specific methods: crush the fruit into juice, add a teaspoon of baking soda powder, mix it into a paste and smear it on the teeth, rinse your mouth after five minutes, and then clean it with a toothbrush.

Whitening teeth with 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. Coconut oil can remove the oil stains and dental stones on teeth. The microbial cells in the mouth are usually covered with lipid or fat, which is incompatible with water. Compared with rinsing with water, coconut oil can combine with lipids, adsorb bacteria from tooth crevices and oral gums, and keep the oral environment healthy.
Specific methods: put a teaspoon of coconut oil in your mouth, rinse your mouth slightly, spit it out after about 15-20 minutes, and then brush your teeth daily.
