Tooth decay most often form in the deep grooves on a tooth’s surface. A fissure sealant is a thin layer of filling material that covers these deep grooves, thus preventing food and bacteria from getting stuck in the grooves and causing decay.
What is a Space maintainer?
Space maintainers help “hold space” for permanent teeth. Your child may need a space maintainer if he or she loses a baby tooth prematurely, before the permanent tooth is ready to erupt. If a primary tooth is lost too early, adult teeth can erupt into the empty space instead of where they should be.
