Brushing and flossing is important for children’s teeth, and a sealant can offer added protection against cavities. A sealant is a resin material applied on teeth to fill in small spaces, according to the American Academy of Pediatrics.

Your child’s dentist can apply the sealant at the office. It creates a barrier that protects tooth enamel from acids and bacteria that could lead to decay.

A sealant — often a good idea for adults, too — may need to be reapplied every few years.
