Fissure Sealants are martials that act as covers for the pits and grooves of the teeth.
They help for prevent bacteria, as well as food debris, from getting stuck in these areas of the teeth. In this way they help protect the teeth from decay – causing elements
Sealants are often applied as soon as the first permanent teeth start to come through, this is usually between 6 and 7 years of age, the rest are usually sealed as soon as they appear which can be any time between 11 and 14 years of age.
They should last at least a couple of years, but it depends on the quality and how well they’ve been placed.
Fissure sealants may work similarly to fillings however, they are not filling and cannot be used to fill cavities or on teeth that have already had fillings.
