Pediatric Dental Sealants

Sometimes brushing is not enough, especially when it comes to those hard-to-reach spots in your child’s mouth. It is difficult for a toothbrush to reach between the small cracks and grooves on teeth. If left alone, those tiny areas can develop tooth decay. Sealants give your child’s teeth extra protection against decay and help prevent cavities.

Understanding Dental Sealants

Dental sealants are a protective coating applied to the chewing surfaces of the back teeth, or molars, which are most prone to decay. They act as a barrier, preventing food particles and bacteria from getting trapped in the tiny grooves of the teeth and causing cavities.

What are dental sealants?

Dental sealants are plastic resins that bond and harden in the deep grooves on the tooth’s surface. When a tooth is sealed, the tiny grooves become smooth, and are less likely to harbor plaque. With sealants, brushing becomes easier and more effective against tooth decay.

The sealant application process

The process is straightforward and painless. The teeth are cleaned and prepared with a special solution before the sealant is painted on and hardened with a light. It takes only a few minutes per tooth.

When are dental sealants applied?

Sealants are typically applied to children’s teeth after their permanent teeth have erupted as a preventive measure against tooth decay. It is more common to seal “permanent” teeth rather than “baby” teeth, but every patient has unique needs, and the dentist will recommend sealants on a case-by-case basis.

How long do dental sealants last?

Sealants last from three to five years, although it is fairly common to see adults with sealants still intact from childhood. A dental sealant only provides protection when it is fully intact so if your child’s sealants come off, let the dentist know, and schedule an appointment for your child’s teeth to be re-sealed.

The benefits of sealants

Essential protection for children’s teeth.

Effective Decay Prevention: Sealants provide a physical barrier that keeps out harmful bacteria and food.
Long-lasting Protection: With proper care, sealants can protect teeth for many years.
Non-Invasive Procedure: Applying sealants is a quick, pain-free process with no drilling or removal of tooth structure.
Saves Time and Money: By preventing cavities, sealants reduce the need for fillings, crowns, or caps later on.
Ideal for Children and Teens: Especially beneficial for those who are at higher risk of tooth decay.

Caring for sealants

Sealants require no special care beyond regular brushing and flossing. Regular dental check-ups are important to monitor the sealants and reapply them if necessary.

Are sealants right for your child?

Sealants are a great option for most children and teenagers, particularly those prone to cavities. They are most effective when applied as soon as the permanent molars come in, so we recommend discussing this preventive treatment at your child’s next dental visit.
