What is fissure sealant?
A dental sealant is a protective layer that is brushed onto the chewing surfaces of teeth to 'seal them off' from the plaque and bacteria that cause cavities to form.
Typically, sealants are applied to the molars, because it is these teeth that do the most chewing and have deep crevices in which bacteria can hide. The sealant will fill in and cover any crevices on the tooth to act as a shield from the bacteria.
What makes them even better is that the sealant application process is quick and painless!
