Dental Sealants

What are dental sealants?

Dental sealants are thin plastic coatings that are applied to the grooves on the chewing surfaces of the back teeth to protect them from tooth decay. Most tooth decay in children and teens occurs on these surfaces.  Sealants protect the chewing surfaces from tooth decay by keeping germs and food particles out of these grooves.

Which teeth are suitable for sealants?

Permanent molars are the most likely to benefit from sealants. The first molars usually come into the mouth when a child is about 6 years old. Second molars appear at about age 12. It is best if the sealant is applied soon after the teeth have erupted, before they have a chance to decay.

Are sealants just for kids?

No. Sealants are indicated for back teeth that have not been filled, and have deep groves. Teeth erupt into the mouth with deep pits and fissures. If the chewing forces don’t wear down or smooth some of this anatomy a dental sealant would be effective in the prevention of cavities.

How are sealants applied?

Applying sealants does not require drilling or removing tooth structure. The process is short and easy. After the tooth is cleaned, a special gel is placed on the chewing surface for a few seconds.  The tooth is then washed off and dried. Then, the sealant is painted on the tooth.  We will shine a light on the tooth to help harden the sealant. It takes about a minute for the sealant to form a protective shield.

Are sealants visible?

Sealants can only be seen up close. Sealants can be clear, white, or slightly tinted, and usually are not seen when smiling.

Will sealants make teeth feel different?

As with anything new that is placed in the mouth, you may feel the sealant with the tongue. Sealants, however, are very thin and only fill the pits and grooves of molar teeth.

How long will sealants last?

A sealant can last for as long as 5 to 10 years. Sealants should be checked at your regular dental appointment and can be reapplied if they are no longer in place.

Will sealants replace fluoride for cavity protection?

No. Fluorides, such as those used in toothpaste, mouth rinse, and community water supplies also help to prevent decay, but in a different way. Sealants keep germs and food particles out of the grooves by covering them with a safe plastic coating. Sealants and fluorides work together to prevent tooth decay.
