Patient With Open Throat In Dentist Office.

Fissure sealants are a hard protective coating usually applied on the biting surfaces of the molar and premolar teeth. These sealants are placed as a preventative measure if the teeth have deep grooves and fissures. These areas are more susceptible to dental decay as they are very deep and narrow and collect plaque bacteria and debris that cannot be easily accessed and cleaned by the toothbrush bristles when brushing. The plaque bacteria and debris trapped in these fissures produce acids that may go on to cause dental decay on these biting surfaces. When these grooves are sealed off the risk for dental decay in these areas is greatly reduced. Crona | Hygienist
