The teeth are cleaned and chewing surfaces are conditioned to help the sealant adhere to the tooth. The sealant is ” painted onto the chewing surface, whre it flows into the pits and fissures, bonds to the tooth and hardens. A special curing light may be used to help the sealant harden.
How long do sealants last?
