Dental Sealants

Pit and fissure decay (cavities) can begin early in life and continue into adulthood. Dental

sealants can provide a benefit by acting as a barrier to help prevent cavities for children and

adults. Brushing and flossing is recommended to clean the teeth by removing bacterial plaque.

However, the pits and fissures are difficult to clean and these nooks and crannies can hide

bacteria. These chewing surfaces are necessary to keep healthy and free of dental decay.

Dental sealants are a thin, plastic coating that is carefully applied to a prepared tooth. They are

placed on premolars and molars to prevent decay. This dental sealant is bonded to the deep

grooves, therefore “sealing out” the bacteria and acids. The best time to seal teeth are when

they first erupt in the mouth. The 6 year molars are usually the first ones needing sealants.

Baby teeth are less likely to need sealants, since the grooves are usually shallow.

The application of a sealant is pain free and is a simple process for the patient. It is important

for the patient to cooperate during the procedure, since moisture control is important. Saliva

contamination during the application of a dental sealant will make the sealant fail. Dental

sealants are not placed on grooves that are known to be decayed.

Sealants will be checked for wear and chipping. This is routinely done at dental check-ups.

Sealants will generally hold up well under the normal chewing forces. But they will not last

forever, and Wisconsin dentists or dental hygienists can replace sealants as necessary. A sealant

may last several years.

Sealants are a great preventive dentistry action. They are a key component in preventing tooth

decay and keeping the mouth healthy.
