Most tooth decay occurs on the deep grooves on the surfaces of the back teeth. Your dentist may choose to apply a sealant to these areas to protect them from decay. Sealants are very thin epoxy resin-based plastic coatings that last years before reapplication is needed.
How are sealants applied?
Applying sealants is a very short and simple procedure. Your dentist will clean your teeth, then apply a gel for a few moments, then wash the gel off and apply the sealant with a brush. It only takes a moment to dry. Both children and adults can benefit from sealants as they contain fluoride to protect every tooth from tooth decay.
