(HealthDay News) -- Coating the molars with a special covering can help thwart bacteria and prevent cavities, dental health experts say.
The American Dental Association says a dental sealant can:
- Provide a protective covering for teeth against bacteria that feed on food particles.
- Prevent bacteria from creating acids that produce holes in the teeth.
- Supplement regular brushing and flossing, reducing the risk of cavities by about 80 percent.
