Pit-and-fissure sealants are one of the most underutilized interventions for preventing carious lesions. Numerous randomized controlled clinical trials have shown sealants to be efficacious in preventing caries, especially among children.
Nobody looks forward to having a cavity drilled and filled by a dentist. Now there’s an alternative: an antimicrobial liquid that can be brushed on cavities to stop tooth decay — painlessly.
In dental circles, the question of sealants has been hotly debated for nearly 50 years, and at least since the ADA awarded the product its seal of approval in 1976.
But are they safe? Hermetically sealing a tooth may sound odd, if not unnecessary, but what has concerned researchers through the years is that dental sealants can contain the same chemicals that caused controversy when present in plastic baby bottles: bisphenol-A (BPA) or its chemical cousin, bisphenol-A dimethacrylate (BPA-DMA).
Dental sealants are a quick, easy, and relatively cheap (as opposed to the dentist bills you’ll accumulate for root canals) solution for preventing cavities. Although the idea behind sealants is not new, they’re quickly becoming the go-to treatment for kids who need extra help in the dental department.
Your dentist has probably offered dental sealants for your child. Mine has. Without knowing whether they work, I’ve always accepted them. Turns out, this was a good move.
Sealants are thin, plastic coatings painted on the chewing surfaces of the back teeth.
Sealants are put on in dentists' offices, clinics, and sometimes in schools. Getting sealants put on is simple and painless. Sealants are painted on as a liquid and quickly harden to form a shield over the tooth.
