A: Sealants are basically highly flow able composites with fluoride releasing property. They  are made to flow in to the naturally occurring pits and grooves on the chewing surfaces of the back teeth where most cavities in children are found

A: Research shows that sealants can last for many years if properly cared for. So, your child will be protected throughout the most cavity-prone years. If your child has good oral hygiene and avoids biting hard objects, sealants will last longer. Your dentist will check the sealants during routine dental visits and can recommend reapplication or repair when necessary.

A: The application of a sealant is quick and comfortable. It takes only one visit. The tooth is first cleaned. It is then conditioned and dried. The sealant is then flowed onto the grooves of the tooth and allowed to harden or hardened with a special light. Your child will be able to eat right after the appointment.

A: The natural flow of saliva usually keeps the smooth surfaces of teeth clean but does not wash out the grooves and fissures. So, the teeth most at risk of decay—and therefore most in need of sealants - are the six-year and twelve-year molars. Many times the permanent premolars and primary molars will also benefit from sealant coverage. Any tooth, however, with grooves or pits may benefit from the protection of sealants.
