Dental sealants are plastic coatings that are placed on the chewing surface of teeth with grooves or fissures.  Such grooves can be deep and are often narrower than a single bristle of a toothbrush.  As a result, grooves and fissures can be very difficult to keep clean and that is why over 75% of incidents of tooth decay begin in these areas. 

By covering and sealing tooth fissures, sealants provide a smooth surface which protects against decay.  Dental sealants are most typically placed on molars and premolars.  However, if other teeth exhibit deep grooves or fissures, sealants can be used to protect those teeth as well.

Dental sealants can last for many years, providing long-lasting protection.  If, over time, damage such as wear or chipping occurs, a new sealant can be placed on the tooth.

When Sealants May Be Placed

Dental sealants are often placed on permanent teeth once they have fully erupted.  However, in certain circumstances, sealants may also be placed during other stages of the patient's life.  Circumstances when sealants may be used include:

• Baby teeth -- While not a common procedure, sealants may be placed on baby teeth if they have deep grooves and if the child is prone to developing cavities.
• Children and teenagers -- A common time for placing sealants is just after the first permanent back teeth (six-year molars) erupt.  As children are prone to cavities from the age of six to sixteen, sealants may be placed any time during that period as well.
• Adults -- Sealants may be placed on the teeth of adults if deep grooves or fissures are present in teeth without decay.

The Procedure

Applying a dental sealant is a fast and simple procedure.  First, the tooth will be thoroughly cleaned, rinsed with water and dried.  A special solution that will promote bonding of the sealant to the tooth will then be placed on the groove or fissure.  The teeth will then be rinsed and dried again.  Next, the sealant material is placed in the target area and allowed to harden.  While some sealant materials harden on their own, others require the use of a curing light.
