Tips to whiten yellow teeth

Brushing teeth in the morning and evening is an essential procedure in people's daily life. On the one hand, it can keep teeth white, and on the other hand, it can make teeth healthier. But even if they brush their teeth every day, some people's teeth are not white, and are even yellow. Since yellow teeth look ugly, many people have chosen some tips to whiten yellow teeth. However, some of them work, while others do not.

1. Drink green tea

You should know that a chemical element is indispensable for whitening teeth and keeping them healthy and strong, and that is fluoride. Many toothpastes contain this element. Of course, green tea also contains fluoride. Fluoride can combine with the apatite in the teeth, and then play an acid-resistant and anti-caries role. In addition, green tea is rich in fluoride, which can freshen your breath and put you in a good mood.

2. Eat more crude fiber foods

Crude fiber foods can whiten teeth very well. The reason is that when we chew crude fiber foods, the crude fiber rubs against the teeth, which can then clean the remaining food on the teeth and the bacteria growing on the surface of the teeth, thereby preventing tooth decay.

3. Eat more foods containing calcium

Calcium is essential for healthy teeth, so consuming more calcium-rich foods in your daily life is very effective for healthy whitening of teeth. Milk, cheese, etc. contain a lot of calcium. Cheese is not only a good source of calcium, but the acidity and alkalinity in the mouth can be balanced by the calcium and phosphate in the cheese, thereby reducing the activity and growth of bacteria in the mouth and preventing tooth decay. It can also increase calcium to make teeth stronger.

4. Smoke less: Everyone should know that smokers have yellower teeth, which are very ugly. In order to ensure white teeth, don’t smoke.

5. Lemon + apple cider vinegar: If your teeth are yellow, you can mix lemon and apple cider vinegar together and gently rub the yellow parts of your teeth. Do this for a week and the effect will be obvious.

6. Chewing gum: You can chew gum frequently, preferably the sugar-free type. This also helps whiten teeth.
