Sealants are made from tooth-colored acrylic and applied on the surface of the molars and premolars to prevent cavities. The grooves on these teeth' surfaces can house thousands of microbes though they seem just as wide as a small crack. Minute food particles and other debris may also accumulate in them, thereby driving up the chances of getting cavities.
Dental sealants fill in the grooves on the chewing surfaces of the back molars, an area where food particles commonly get caught and cause cavities. Sealants can be applied quickly with no shots or drilling, effectively protecting your child’s teeth for years.
