What Dental Sealants Are and How They Work
Dental sealants are thin, protective coatings applied to the chewing surfaces of the premolars and molars. These back teeth have deep pits and grooves, called fissures, that trap food particles and bacteria even with diligent brushing. Sealants fill these grooves and create a smooth, easy-to-clean surface that prevents bacteria from settling in and causing decay.
The sealant material is a BPA-free resin that bonds to the enamel and hardens to form a durable shield. Once applied, the sealant acts as a physical barrier between the tooth surface and the cavity-causing elements in the mouth. That is why sealants are one of the most cost-effective preventive measures available in dentistry.
Who Should Get Dental Sealants
Children and Teenagers
Sealants are most commonly applied to children's permanent molars shortly after they erupt, typically between the ages of 6 and 14. Applying sealants as soon as the molars appear provides protection during the cavity-prone years of childhood and adolescence. Children who receive sealants have significantly lower cavity rates in their back teeth compared to those who do not.
Adults Without Decay on Molar Surfaces
Adults who have deep grooves on their molars and no existing decay or fillings on those surfaces can also benefit from sealants. Patients with a history of frequent cavities or those who are at higher risk due to dietary habits or dry mouth may find sealants especially valuable.
The Sealant Application Process
Applying dental sealants is quick, painless, and does not require anesthesia. The tooth is cleaned and dried, and a mild etching solution is applied to roughen the enamel surface slightly so the sealant bonds securely. The sealant is then painted onto the grooves and hardened with a curing light. The entire process takes only a few minutes per tooth and can be completed during a regular dental visit.
Dr. Jae Kwak, DDS, PhD, and the dental hygiene team at Jace Dental Care evaluate each patient's teeth to determine which surfaces would benefit most from sealant placement. The application is straightforward and comfortable, making it easy for children and adults alike.
How Long Dental Sealants Last
Dental sealants can last up to 10 years with proper care. During regular dental checkups, the dentist inspects the sealants for wear and can reapply them if needed. Even partial sealants provide some degree of protection, but intact sealants offer the highest level of cavity prevention.
