Black spots on teeth may be caused by pigmentation, caries and so on.
1. Pigmentation: Drinking strong tea, strong coffee or colored drinks, smoking, etc. can easily lead to black spots on the teeth, you can remove the black spots by way of scaling, and try to drink fewer strong colored drinks, quit smoking, etc., and check the oral hygiene regularly, every six months is better.
2. Dental caries: The food residues left in the mouth produce acid under the action of caries-causing bacteria, which leads to acid erosion and demineralization of the teeth, and thus manifests itself as tiny black spots. Shallow caries without symptoms can be removed by grinding the black spots and taking remineralization treatment to prevent further deepening of caries.
It is best to go to the hospital in time to check the black spots on the teeth and take the best treatment after clarifying the cause of the disease.
