Tooth decay is increasingly common in preschoolers. Beyond being painful, decay can lead to premature tooth loss and childhood periodontal disease. Dental sealants are a key preventive measure, especially when combined with biannual checkups and a solid home care routine, helping to protect children’s teeth and maintain healthy smiles.

How Do Sealants Protect Teeth?

Dental sealants are primarily used to protect molars, the larger, flatter teeth at the back of the mouth. Molars are difficult to clean and account for four out of five instances of tooth decay. Bacteria can hide in the nooks and fissures of these teeth, which a toothbrush cannot easily reach.

If a pediatric dentist determines a child is at high risk for tooth decay, additional teeth such as bicuspids may also be sealed. The sealant acts as a barrier, preventing bacteria and food particles from contacting vulnerable enamel. Sealants complement fluoride use and general oral care but are not a replacement for them.

How Are Sealants Applied?

  • The dentist thoroughly cleans and prepares the teeth.
  • Liquid plastic sealant is painted onto the targeted molars. Some sealants appear bright pink when wet to ensure all fissures are coated.
  • The sealant either self-hardens or is cured with a blue spectrum light, forming a clear, durable protective layer.

The procedure is painless and can usually be completed in a single office visit.

When Should Sealants Be Applied?

Sealants are generally applied as soon as primary molars emerge and for permanent molars as soon as they appear. The durability of a sealant depends on the child’s oral habits, and they may need replacement over time. Biannual dental appointments allow the pediatric dentist to check the condition of the sealant and ensure no gaps have formed, which could allow decay to develop.

If you have questions or concerns about dental sealants for your child, please contact your pediatric dentist.
