Sealants (Prevent Cavities)

Dental sealants are the most under-utilized, cost effective means of preventing tooth decay. 80% of cavities occur in the areas of pits and fissures of the molar and premolar teeth. Seal out decay before decay invades your tooth and becomes more costly to your dental health and your pocket. Sealants are highly recommended for everyone.



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.

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. The dentist or dental hygienist also may 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 a child talks or smiles.

Will sealants make teeth feel different?
As with anything new that is placed in the mouth, a child may feel the sealant with the tongue. Sealants, however, are very thin and only fill the pits and grooves of molar teeth. They will typically feel very smooth to the tongue.

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.

Why is sealing a tooth better than waiting for decay and filling the cavity?
Decay damages teeth permanently. Sealants protect them. Sealants can save time, money, and the discomfort sometimes associated with dental fillings. Fillings are not permanent. Each time a tooth is filled, more drilling is done and the tooth becomes more brittle and damages the overall integrity of the tooth.
