Fissure sealants are an ideal way of helping to prevent decay. They are a very thin protective layer which is painted onto the top surface of permanent molar teeth once they have come through. These teeth are particularly prone to decay as the top surfaces are covered in tiny fissures and grooves which are virtually impossible to clean with a toothbrush. Applying a sealant means bacteria and food remnants are unable to enter the fissures and grooves, significantly reducing the risk of decay. For more information, please ask our hygienist.
