If it is dental plaque and tartar caused by bad eating habits or unclean oral hygiene habits, I suggest you go to the hospital dental department to wash your teeth, and brushing your teeth can't be brushed off.

If it is dental fluorosis or tetracycline, it is difficult to wash teeth, and you can do tooth bleaching. In addition, there are light-cured resin whitening restoration and porcelain veneer restoration ... which can make teeth whitening and beautiful.

We should develop good eating habits and pay more attention to the cleanliness of oral hygiene. For example, after eating sugar and snacks, rinse with water; Brush your teeth in the morning and evening, remember to brush carefully; Eat more crude fiber and coarse grains ... and of course go to the hospital for oral care regularly.
