Dental Sealants for Teens: Are They Still Effective?

Dental sealants are frequently used in pediatric dentistry. They act as a protective barrier against decay, reducing the risk of cavities. But are they still effective for teenagers? 

Pediatric dentistry extends to treatment for adolescents through the age of 18. Some patients may decide to transition to an adult or family dental practice earlier, but it is completely acceptable to remain in the care of your pediatric dentist through the adolescent years. This means that pediatric dental treatments are still available, including dental sealants. 

What Are Dental Sealants? 

A dental sealant is a thin layer of resin applied to the surface of a tooth on top of the enamel. It fills in crevices and spaces where plaque can gather, preventing decay and making it easier to keep the teeth clean. The sealant is applied to the tooth in liquid form and hardens in a matter of minutes. Dental sealants can be applied in one visit, making them a quick and efficient treatment. 

Benefits of Dental Sealants 

• Prevent cavities. Dental sealants are extremely effective at preventing cavities, especially in molars that are highly susceptible to decay. 
• No anesthesia. The application of dental sealants is a completely painless process that requires no anesthesia. 
• Long lasting results. Dental sealants can protect teeth for many years, even into adulthood. 
• Cost effective. Dental sealants cost less than fillings, making them a more affordable preventive option. 
• Safe. The resin used for dental sealants is a safe, non-toxic material, offering peace of mind for parents. 

When Are Dental Sealants Most Effective? 

Dental sealants are most effective when they are applied as a preventive measure, before cavities develop. Once a cavity has formed, a filling will most likely be required to adequately repair the tooth and stop the spread of decay. While dental sealants can be applied to both primary and permanent teeth, they tend to be used primarily for children and teenagers. 

When Are Dental Sealants Not Effective? 

Dental sealants are not effective for existing cavities or teeth with extensive decay or damage. Adult teeth are less likely to be treated with dental sealants due to a variety of reasons. Research shows that dental sealants are less effective for teeth that have been exposed to bacteria for prolonged periods of time, as adult permanent teeth typically have. Teeth grinding can also shorten the lifespan of dental sealants. 

Are Dental Sealants Right For Your Teen? 

Dental sealants may be an effective preventive treatment for your teen in any of the following scenarios:

• Deep grooves or crevices in teeth. Teeth that have deep grooves or crevices are at a higher risk of plaque accumulation that can lead to the development of cavities. 
• Lack of good oral hygiene habits. Teens do not always exhibit good oral hygiene habits, and dental sealants can help protect teeth from excess plaque buildup due to lack of effective brushing and flossing. 
• Evidence of significant plaque buildup. Some people develop plaque on their teeth at a faster rate than others. If your dentist notices that your teen tends to develop a larger amount of plaque than average, dental sealants may be recommended. 

Frequently Asked Questions About Dental Sealants

Why can’t sealants be used on existing cavities?

The problem with sealing over an existing cavity is that the decay could continue to worsen under the sealant. During a filling, the decay is completely removed, leaving only healthy tooth material behind. 

Do dental sealants require local anesthesia?

The application of dental sealants is a completely painless process, so no anesthesia is required. The procedure is quick and easy.
