A sealant is a plastic coating that fills the grooves of the tooth and is bonded into place. It is a quick and simple dental procedure that can help prevent the need for a filling. Sealants are most commonly placed on the biting surfaces of molar teeth to help prevent dental decay. Teeth that have deep grooves are susceptible to decay because the bacteria that cause decay can hide in those grooves cannot be easily removed with brushing or flossing.
Typically sealants are recommended for molar teeth in young children but can also benefit teeth in some adults.
