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. They are used as a preventative measure by helping keep teeth, especially hard-to-reach surfaces, clean and bacteria-free. 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.
Who is likely to benefit from dental sealants?
Permanent molars are the most likely to benefit. 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. Sealants also offer benefits to teens and adults, especially those with a history of dental cavities. Those with deep grooves or poor dental hygiene may also find dental sealants a good preventative measure against tooth decay.
How are dental sealants applied?
Applying sealants does not require drilling or removing tooth structure. The process is short, easy, and pain free. 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. Sealant application is completed in one dental visit and is often done at the same time as your dental cleaning.
What happens after dental sealants are applied?
Sealants can only be seen up close. They can be clear, white, or slightly tinted, and usually are not seen when a child talks or smiles. 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. A sealant is not a permanent solution, lasting for as long as 5 to 10 years. They should be checked at each regular dental appointment and can be reapplied if they are no longer in place. It is important to ensure the sealant has not been chipped or moved out of place. When damaged, a sealant can act as a food trap which can cause decay.
Are dental sealants covered under insurance?
Dental coverage varies depending on your provider. Dental sealants have been recognized as a preventative care measure against tooth decay – visit our office and our receptionists will be able to help inquire whether your insurance benefits cover dental sealants.
Indicators to help decide the use of dental sealants:
- Patients with a history or high risk of cavities
- Deep pits in the molars where food can get caught
- Poor oral hygiene
- Enamel defects
- Orthodontics appliances
Patients with exceptional oral hygiene will not need to make use of dental sealants.
