1, baking soda to brush your teeth
When brushing your teeth, add some baking soda powder to the toothpaste, do not touch the water, and gently brush the tooth surface, which can effectively remove tooth rust and increase the brightness and whiteness of teeth. Baking soda is edible, but it is an alkaline substance, so don't brush your teeth too hard, otherwise it will easily damage the delicate muscles in your mouth, not only your health, but also your health.
2. Drink more green tea
Tannic acid in green tea can prevent bacteria from sticking to teeth, thus preventing teeth from discoloring and helping to prevent bad breath. Polyphenols in green tea can prevent the growth of oral acid and tissue bacteria. Green tea can also improve oral fluoride level and reduce enamel damage.
3. Brush your teeth and floss regularly.
It is easier to prevent tooth discoloration than to remove tooth stains. Brushing and flossing play a very important role in protecting white teeth. Keeping this habit can keep teeth from discoloring for a long time.
4. Eat more dark green vegetables
Minerals contained in dark green vegetables such as spinach and broccoli help to form a protective film on the surface of teeth to prevent teeth from yellowing. Experts also suggest eating more apples, pears, celery and carrots. Chewing can promote saliva secretion, reduce oral bacteria and contribute to tooth whitening.
Step 5 chew celery
Crude fiber is like a broom, sweeping away some food residue from teeth. In addition, the harder you chew, the more you can stimulate saliva secretion, balance the pH in the mouth, and achieve natural antibacterial effect.

3. After meals, snacks and carbonated drinks, rinse your mouth with clear water in time, remove food residues or chew sugar-free chewing gum, which can reduce the risk of dental caries.
