Sealants – Protecting Teeth, Preventing Decay

Dental Sealants are used to protect the chewing surface of back teeth from decay.  These surfaces are difficult to keep clean due to the fact that there are pits and fissures in the teeth where tooth brush bristles cannot reach.  Food debris and bacteria in plaque, left in these pits and fissures, produce acids which dissolve tooth structure, resulting in tooth decay.  Sealants are resin materials applied to the chewing surface of back teeth to form a barrier over these susceptible surface areas.


How are Sealants Applied?

The procedure is simple and painless.  First, the teeth are cleaned and conditioned with a gel to prepare the surface for bonding.  After rinsing and drying, the teeth sealant is applied and hardened with a blue light.

Dental Sealants usually last for many years and can be re-applied as needed, throughout life.  They are extremely cost-effective in preventing pit and fissure decay, when applied as soon as the permanent back teeth erupt.



Fluoride varnish is applied to the smooth surface and cervical areas of the teeth.  It remains on the tooth for several hours, allowing the fluoride to penetrate into the tooth structure.  It is used to prevent decay, re-mineralize the tooth surface, and to treat dentin hyper-sensitivity.

Fluoride varnish does not promote fluorosis.
