Sealants are a great way to prevent decay on the molars of children.
The grooves and pits of the back teeth are not easily cleaned and often cavity-causing food sticks in them. Sealants applied as the teeth erupt at about 6 years old and again at 12 years old fill in the grooves so that cavity-causing food no longer can fill the grooves. Research shows a significant decrease in decay when sealants are applied to the teeth.
Sealants are very effective when carefully applied.
First a diagnostic laser is used to make absolutely sure there is no decay in the grooves of the tooth. Next, the tooth grooves are air abraded to completely clean the pits and fissures of all food debris and plaque. The tooth is then conditioned; the sealant applied and then light cured. A well-placed sealant can last for years.
