Brushing your teeth is important, but dental sealants may be the best way to prevent kids from getting cavities. School-age children without sealants have three times more cavities than children with sealants.

Dental sealants are a thin coating that is painted on teeth to protect them from cavities. Dr. Valeria Barba, a dentist in New Jersey, told Healthline that sealants are the “most conservative” noninvasive treatment in dentistry

The Center for Disease Control (CDC) report state that dental sealants prevent 80 percent of cavities for two years after application.  These sealants can be retained in the mouth for up to nine years, according to the CDC.  If applied right, they can last a lifetime.


Pits and Fissures are the areas of the tooth that look like “canyons” and are the most common place for decay to occur


ADA Guidelines:

Placement of pit-and fissure sealants significantly reduces the percentage of non-cavitated lesions (cavities that have not broken through the enamel layer) that progress in children, adolescents and young adults for as long as five years after placement, compared with unsealed teeth.


  • Should be placed in pits and fissures of children’s primary teeth when determined that the tooth, or the patient, is at risk for developing caries
  • Should be placed on pits and fissures of children’s, adolescents and adult’s permanent teeth when it is determined that the tooth, or the patient, is at risk for developing caries.
  • Pit and fissure sealants should be placed on early (non-cavitated) caries lesions (decay) in children, adolescents, young adults, and adults to reduce the percentage of lesions that progress.

In addition to preventing cavities, sealants can ensure that the teeth stay intact. Once a tooth is drilled and filled, restored, or extracted, the natural structure is compromised. There is a lifetime cost associated with maintaining the restored tooth or implant.


“The main problem with sealants is the lack of awareness”
