Dental Sealants
This effectively “seals” the deep grooves, acting as a barrier and protecting enamel from plaque and acids.
Dental sealants protect the depressions and grooves of your teeth from food particles and plaque that brushing and flossing can’t reach.
Easy to apply, dental sealants take only a few minutes to seal each tooth. Sealants hold up well under the force of normal chewing and can last several years before a reapplication is needed.
Children and some adults can benefit from dental sealants in the fight against tooth decay.
Who Should Get Sealants?
Because of the likelihood of developing decay in the depressions and grooves of the premolars and molars, children and teenagers are candidates for sealants. However, adults without decay or fillings in their molars can also benefit from sealants.
Typically, children should get sealants on their permanent molars and premolars as soon as these teeth come in. In this way, the sealants can protect the teeth through the cavity-prone years of ages 6 to 14.
In some cases, dental sealants may also be appropriate for baby teeth, such as when a child’s baby teeth have deep depressions and grooves. Because baby teeth play such an important role in holding the correct spacing for permanent teeth, it’s important to keep these teeth healthy so they are not lost too early.
How Are Sealants Applied?
Applying sealant is a simple and painless process. It takes only a few minutes for your dentist or hygienist to apply the sealant to seal each tooth. The application steps are as follows:
- First the teeth that are to be sealed are thoroughly cleaned.
- Each tooth is then dried, and cotton or another absorbent material is put around the tooth to keep it dry.
- An acid solution is put on the chewing surfaces of the teeth to roughen them up, which helps the sealant bond to the teeth.
- The teeth are then rinsed and dried.
- Sealant is then painted onto the tooth enamel, where it bonds directly to the tooth and hardens. Sometimes a special curing light is used to help the sealant harden.
