Dental sealants are thin composite coatings which are micromechanically bonded to tooth that prevent access to cavity causing bacteria, plaque, and food. They are applied to the pits and fissures of our adult permanent molar teeth. The purpose of a sealant is to prevent decay.
According to the American Academy of Pediatric Dentistry, "Pit and fissure sealants account for 80-90% of all caries in permanent posterior teeth and 44% in primary teeth. Placement of sealants have shown a reduction of caries incidence of 86% after 1 year. "
Sealants prevents plaque and bacteria from getting into the grooves of teeth so cavities do not occur.
At Sequoia Pediatric Dentistry, we are equally concerned with xray radiation as you. That is why we offer digital radiographs. Digital xrays reduce radiation exposure by 4 times compared to conventional analog radiographs.
Also, we do not require you to take a radiograph at every visit. Please let us know if you are concerned with radiographic exposure and would like us to take less radiographs.
