What Are Dental Sealants?

Brushing does a lot to protect your teeth, but a toothbrush cannot always reach every tiny space. This is especially true with the back teeth. Molars have small pits and grooves across their chewing surfaces. Food and bacteria can collect in those spots, even when someone brushes regularly.

Dental sealants help protect those hard-to-clean areas. A sealant is a very thin layer of material that a dentist places over the top of a tooth. It settles into the grooves and hardens, leaving behind a smoother surface. With fewer deep spaces for food to get stuck, the tooth may be easier to keep clean.

Sealants are most often placed on the molars, since those teeth tend to have the deepest grooves and do most of the chewing. Cavities often begin in these areas.

Many children receive sealants soon after their permanent back teeth come in. The first adult molars commonly appear when a child is around six years old. Another set comes in later. Placing sealants early can protect those teeth during the years when brushing habits may still be developing.

That does not mean dental sealants are only for children. Teenagers and adults may benefit from them too. Some people naturally have deeper grooves in their teeth, making those areas harder to clean. Others may have a history of frequent cavities. A dentist can look at the teeth and decide whether sealants would provide useful protection.

The appointment itself is fairly simple. The dentist or hygienist cleans the tooth first and makes sure the surface is dry. A liquid is placed on the tooth for a short time to help the sealant stick. The tooth is then rinsed and dried before the sealant is brushed over the chewing surface.

A small light may be used to harden the material. Once that is finished, the sealant is ready to protect the tooth.

There is no drilling involved, and the tooth does not need to be numbed. Most patients do not feel anything other than the dentist working around the tooth. The process takes only a few minutes, although younger children may need breaks if they have trouble keeping their mouths open.

The sealant may feel slightly strange at first. The tongue is very sensitive and may notice even a small change in the surface of a tooth. That feeling normally fades once the person gets used to it.

Sealants do not replace brushing, flossing, or regular dental visits. They are simply another form of protection. Bacteria can still collect around the gums and between the teeth, so daily care remains important.

A dental sealant can last for several years, although chewing eventually wears it down. It may also chip or pull away from part of the tooth. Dentists check sealants during routine exams and can add more material when needed.

Not every tooth requires a sealant. A tooth with wide, shallow grooves may already be easy to brush. Teeth that have large fillings or existing decay may need another type of care. The dentist will consider the condition of the tooth and the person’s risk of cavities before making a recommendation.

Insurance often covers dental sealants for children, although every plan is different. Coverage for teenagers or adults may be more limited. The dental office can explain the expected cost before treatment is completed.
