there are deep fissures on a tooth, dental
plaque can easily accumulate in these fissures where the
toothbrush bristles cannot access to and clean these areas
thoroughly. Therefore, these teeth are prone to tooth decay.
|Seal up fissures and prevent tooth decay|
Fissure sealant is a tooth-coloured or transparent material, which is well adhered to the enamel of the tooth. Fissure sealant seals off the fissures of a tooth to prevent tooth decay by blocking the plaque bacteria in the fissures from getting access to the dietary sugars.
