Dental sealant is a thin, plastic coating painted on the chewing surfaces of teeth -- usually the back teeth (the premolars and molars) -- to prevent tooth decay. The sealant quickly bonds into the depressions and grooves of the teeth, forming a protective shield over the enamel of each tooth
How Long Do Sealants Last?
Sealants will often last for several years before they need to be reapplied. During your regular dental visit, your dentist will check the condition of the sealant and can reapply them as needed.
