Sealants
A sealant is a resin that is applied to the chewing surfaces of the back teeth. This resin covers the pits and fissures in these teeth, covering them fully and forming a strong barrier against acid and plaque attacks. Sealants may last several years before they need to be replaced; each time you come in for a dental checkup your hygienist will check for loose or worn sealants that will need to be replaced.
