Sealants are primarily a preventative service. They involve placement of a liquid resin which is flowed into the cleaned/prepared grooves and pits on the biting surfaces of teeth. Once in place, the resin is cured to harden it. Sealants are most commonly placed on molars, but can be placed on other teeth as well. They function to keep bacteria from getting into the small developmental grooves of teeth, where bacteria can colonize and cause decay. The sealants have been in use for decades and have resulted in prevention of decay for a tremendous number of patients. Please ask us about them.
