Sealants protect teeth from cavities and decay. The most common area to get decay is on permanent back teeth or molars. Molars have deep grooves and pits on the chewing surfaces where food and bacteria can hide and form cavities.
Sealants are white or tooth shaded material that is bonded to the chewing surfaces of the back teeth, sealing off deep grooves and pits. This makes the grooves of the teeth smoother so your toothbrush can more easily keep the tooth clean.
Applying sealants is a simple procedure. The teeth are first cleaned, then etched with a solution to help the sealant adhere. Next, the sealant is brushed on, then a special light is used to harden the material. The procedure requires no anesthesia or drilling and can be completed in one visit.
