The grooves and depressions that form the chewing surfaces of the back teeth are extremely difficult (if not impossible) to clean of bacteria and food. As the bacteria reacts with the food, acids form and break down the tooth enamel, causing cavities. Recent studies indicate that 88 percent of total cavities in American school children are caused this way.
Tooth sealants protect these susceptible areas by sealing the grooves and depressions, preventing bacteria and food particles from residing in these areas. A sealant is a glass-like material, resin, that is usually applied to the chewing surfaces of the back teeth, molars and premolars. Te sealant bonds into the grooves of these teeth, creating a barrier, thus protecting enamel from plaque and acid.
Since sealants are gently applied and cost significantly less than a filling, we highly recommend this preventive procedure. Sealants also last for several years, but they do need to be checked during regular appointments.
