A sealant is a plastic material that is usually applied to the chewing surfaces of the back teeth. This plastic resin bonds on to the retentive depressions and grooves (pits and fissures) of the chewing surfaces and eliminates the chance of decay occuring. The sealant also acts as a barrier, protecting enamel from plaque and acids. We recommend sealants for the permanent molars and premolars as soon as they fully erupt to help protecting the teeth from decay.
Extensive research has shown that optimal levels of fluoride not only reduce cavities in children and adults, but it also helps repair the early stages of tooth decay even before the decay is visible.
We also use a great fluoride varnish. The varnish is used to help patients to prevent caries (cavities) or recurrent decay around existing fillings or crown margins, which helps prolong the life of your restorations. Varnish can dramatically improve teeth sensitivity due to gum recession and exposed root surfaces as well.
