What are Dental Sealants?

Dental sealants are thin plastic coatings which are applied to the chewing surfaces of the back teeth to prevent decay.  Most tooth decay in children and adolescents occurs on the chewing surfaces of these back teeth or molars.  This is because molars have irregular surfaces with pits and grooves which tend to trap food and bacterial debris.  Sealants flow into and coat these pits and grooves so that bacteria cannot multiply and cause decay.

Which Teeth are Suitable for Sealants?

The teeth most likely to benefit from sealant application are the first and second molars and the first and second bicuspids just after they have erupted and before they have had a chance to decay.  First molars generally appear at about six years of age and second molars and bicuspids at about twelve years of age.  After an examination, our doctors will determine which teeth can be sealed.

How Are Sealants Applied?

Applying sealants is quite simple and may be done by a dentist or a licensed dental auxiliary.  First, the teeth are cleaned.  Then the teeth to be sealed are dabbed with a cleansing solution which prepares the tooth surface so that the sealant will bond to it properly.  After the tooth is prepared, the sealant is painted onto the tooth.  It flows into the pits and grooves and hardens in about 60 seconds.  After sealing, bacteria cannot reach the pits and grooves and cause decay.  The application of sealants requires no drilling or removal of the tooth surface.

Are Sealants Visible?

Yes.  Sealants can be clear, white or slightly
