Dental Sealants: Protecting Cavity-Prone Teeth

The grooves on the chewing surfaces of back teeth can be difficult to keep completely clean, especially when those grooves are deep or narrow. Dental sealants create a thin protective covering over these areas to help reduce the chance of cavities developing in vulnerable tooth surfaces.

Why Are Back Teeth More Likely to Need Sealants?

Molars and some premolars naturally have pits and grooves across their chewing surfaces. In some teeth, these areas are deep enough that toothbrush bristles have difficulty cleaning them effectively.

When plaque and food repeatedly collect in those grooves, the tooth can become more vulnerable to decay.

A sealant covers the susceptible chewing surface, providing another layer of protection while still allowing you to brush the tooth normally.

Who May Benefit From Dental Sealants?

Sealants are commonly associated with children and teenagers because newly erupted permanent back teeth can be vulnerable to cavities. But age alone does not determine whether someone needs a sealant.

Dr. Christine Chin may consider factors such as:

Children, teenagers and some adults may benefit from sealants depending on the condition of their teeth and their individual cavity risk.

Does My Child Need Dental Sealants?

Not every child automatically needs sealants on every back tooth.

As permanent molars come in, Dr. Chin can examine their chewing surfaces and consider your child’s cavity history, oral hygiene and the shape of the teeth.

If a tooth has deep grooves that are difficult to clean and is at greater risk for decay, placing a sealant may provide useful additional protection.

Can Adults Get Dental Sealants?

Yes. Although sealants are frequently used in younger patients, an adult tooth with susceptible pits or grooves may also be considered for a sealant when appropriate.

Dr. Chin will evaluate the tooth first because existing fillings, decay and other conditions can affect whether a sealant makes sense.

What Happens When a Dental Sealant Is Applied?

Applying a sealant is generally a straightforward procedure and does not require removing healthy tooth structure in the way a filling does.

The tooth is cleaned and carefully isolated so the surface can remain dry. The enamel is prepared to help the sealant adhere properly, and the sealant material is applied to the pits and grooves of the tooth.

The material is then hardened as appropriate for the type of sealant being used, and the bite can be checked afterward.

Do Dental Sealants Hurt?

Placing a sealant is generally comfortable because the material is applied to the surface of the tooth rather than requiring the removal of healthy tooth structure.

For children who may be nervous about dental treatment, knowing what will happen beforehand can make the experience easier. Dr. Chin and the Cedar Hills Dental Care team take a patient, reassuring approach and can explain each step as they go.

How Long Do Dental Sealants Last?

Sealants can remain protective for years, but they can wear, chip or partially come away over time.

That’s why Dr. Chin and the dental team check existing sealants during regular dental examinations. If a sealant has worn or is no longer adequately covering the intended area, Dr. Chin can determine whether it should be repaired or replaced.

Do Sealants Replace Brushing, Flossing or Fluoride?

No. A sealant protects specific pits and grooves on the chewing surface of a tooth. It does not protect every surface of the tooth and does not eliminate the need for daily dental care.

Brushing with fluoride toothpaste, cleaning between the teeth, appropriate fluoride exposure, a tooth-friendly diet and regular dental examinations all remain important.

Think of sealants as one possible part of a larger cavity-prevention plan—not a replacement for it.
