A fissure sealant is a liquid resin that sets hard after a few minutes.
Designed to fill small fits or fissures in the back teeth that trap food and are hard to clean, fissure sealants make the tooth smoother and easier to clean. Fissure sealants create a protective barrier against plaque, bacteria and cavities – protecting your teeth against possible infection.
Fissure sealants are offered to patients of all ages, and are often recommended for young children who find it hard to clean their back teeth. The procedure is relatively quick, lasting for a few minutes for each tooth. Fissure sealants typically last for several years.
