FISSURE SEALANTS
Pits and Fissures are small developmental grooves and crevices on the biting surfaces of back teeth (A)
They are deep in the enamel and are usually 'V' shaped in cross section (B). They tend to be difficult to keep clean as bacteria and food can trap in the bottom of the 'V' and even toothbrushing may not adequately remove the debris. Hence newly erupted teeth are prone to decay.
To minimize the risk of decay, the pits and fissures can be sealed. A sealant is a tough tooth-coloured coating placed onto the tooth surface. It leaves a much smoother surface which is easier to clean and therefore helps to prevent decay. (C) (D).
We are happy to advise parents as to the optimal time for placing of these on newly erupted teeth.
