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.
