The
most common form of tooth decay involves the biting (occlusal)
surface of the back teeth. This can frequently be seen in
young children, soon after their adult molars have erupted.
The occlusal surface is particularly vulnerable to decay because
it may have convoluted fissures, which collect plaque.
An excellent way to prevent this type of
decay from progressing is to seal the fissures with an adhesive
sealant. This smoothes the fissure and prevents plaque from
accumulating. We are most likely to carry out this procedure
if a child has convoluted fissures, or if there are other
teeth in the mouth which have already needed fillings.
Fissure sealants have proved to be so successful
that we now use a very similar technique to treat early occlusal
decay in adults. We call this a "Preventive Resin Restoration".
Any decay is removed and the resulting cavity
filled with an adhesive filling material. The remaining fissures
and the surface of the cement is sealed with a white adhesive
material. This treatment is so conservative that very little
drilling is needed, and local anaesthetic is frequently unnecessary.
