Research shows sealants last for many years.  Therefore, your child should be protected throughout most of his/her adolescence.  By avoiding biting hard objects and focusing on proper hygiene, sealants will last even longer.  If, however, a sealant breaks down, it can be easily replaced.


Sealants are protective coatings placed on the biting surfaces of molar (primary and permanent) teeth to prevent cavities.   Sealants act as a shield for the tooth protecting it from food, plaque, bacteria, and acids that in combination cause cavities.  According to research transmitted by the American Academy of Pediatric Dentistry (AAPD), sealants reduce the risk of cavity formation by 67%.  Investing in early prevention decreases future costs associated with fillings and/or crowns.

What are Sealants?

How are Sealants applied?

  1. Plaque and food debris is removed from the tooth.
  2. A blue etching gel is placing on the tooth surface and allowed to remain for less than half a minute.
  3. The etching gel is rinsed away with water and the tooth is dried.
  4. A thin layer of liquid sealant (plastic) material is flowed onto the top surface of the tooth.
  5. A light is placed over the sealant which hardens the sealant (plastic) material.
