Sealing Out Tooth Decay
Tooth decay is common in preschoolers and can lead to pain, premature tooth loss, and childhood gum disease.
Dental sealants help prevent cavities, especially when combined with regular dental checkups and good daily oral care. Sealants strengthen the mouth’s defenses and keep smiles healthy.
How Sealants Protect Teeth
Sealants are applied to molars, which are prone to decay due to their grooves and pits. These areas are hard to clean and account for four out of five cases of tooth decay. For children at higher risk, additional teeth like bicuspids may also be coated.
Sealants act as a barrier against bacteria and food, but they do not replace fluoride or general oral care. They are often less costly and more comfortable than fillings.
Application Process
Most sealants are liquid plastic. The dentist cleans the teeth, paints on the sealant, and it hardens either naturally or under blue light. Some sealants are pink when applied to ensure complete coverage. The procedure is painless and usually completed in one visit.
When to Apply Sealants
Sealants are applied when primary molars appear and should be monitored at biannual visits. Permanent molars should be sealed as soon as they emerge. Depending on a child’s habits, sealants may last the lifetime of the tooth or need replacing.
If you have questions about sealants, contact your pediatric dentist.
