Dental Sealants for Kids and Adults

Ideal for both children and adults, dental sealants offer a smooth coating that shields vulnerable areas of the teeth—particularly the back molars—from harmful bacteria and acids. At Cornell Dental, we provide high-quality teeth coating for cavities to help you and your family maintain long-term oral health.



What Are Dental Sealants?



Dental sealants are thin, protective coatings applied to the chewing surfaces of molars and premolars. These areas often have deep grooves and pits that can trap food and plaque, making them difficult to clean thoroughly with regular brushing.

Sealants act as a barrier, protecting enamel from plaque and acids that can lead to cavities. Made from materials like plastic resin or glass ionomer, sealants bond to the tooth surface and are either clear or tooth-colored, making them virtually unnoticeable.

•  Barrier Protection - Sealants block out bacteria and food particles from settling in deep grooves.

•  Common Application Areas - Most often applied to molars and premolars where decay is more likely.

•  Material Safety - FDA-approved and widely endorsed by dental associations for safety and effectiveness.

•  Appearance - Transparent or tooth-colored, blending seamlessly with natural teeth.

By sealing these hard-to-reach areas, non-invasive cavity prevention becomes possible without drilling or discomfort.



How Dental Sealants Prevent Cavities



Sealants work by filling in the deep fissures of the back teeth, creating a smooth surface that’s easier to clean. These grooves can be too narrow for toothbrush bristles to reach, allowing plaque and food particles to build up.

When combined with regular brushing, flossing, and fluoride treatments, dental sealants significantly enhance your overall oral health protection.

•  Protective Shield - Prevents bacteria and acids from reaching the enamel in deep pits and grooves.

•  Enhanced Cleaning - Makes brushing more effective by smoothing tooth surfaces.

•  Supplementary Care - Works alongside fluoride and good oral hygiene habits for maximum cavity prevention.

•  Microscopic Benefits - Studies show teeth with sealants resist decay far better than untreated teeth.

While sealants are not a replacement for brushing and flossing, they are an essential addition to any preventative dental care routine.



Who Should Get Dental Sealants?



Dental sealants are most commonly associated with children, but they’re also beneficial for teens and adults. They’re typically recommended when the first and second molars emerge, usually between ages 6 and 12.

•  Children - Ideal for kids as soon as their permanent molars come in.

•  Teens - Suitable for adolescents who missed sealants earlier or are at high risk for cavities.

•  Adults - Effective for adults with healthy molars that have no existing fillings or decay.

•  High-Risk Individuals - Beneficial for those with deep grooves or a history of dental caries.

Pediatric dental sealants are a standard part of preventive care, but many adults may not realize they too can benefit from this simple treatment offered by a general dentist.



What to Expect During the Sealant Procedure



The application of dental sealants is a quick, comfortable process that usually takes just one visit. It’s entirely non-invasive and does not require any drilling or anesthesia.

•  Tooth Preparation - The dentist thoroughly cleans and dries the teeth to remove any debris.

•  Etching Application - A mild acid solution is applied to help the sealant adhere.

•  Sealant Placement - The sealant material is painted onto the tooth surface.

•  Curing Light - A special light hardens the sealant, bonding it securely to the tooth.

Most patients can resume normal eating and drinking right after the sealant application process.



How Long Do Dental Sealants Last?



With good oral hygiene and regular dental checkups, dental sealants can last for several years. Over time, sealants may wear down or chip, but they can be easily reapplied as needed.

•  Durability - Many sealants last between 5 to 10 years with proper care.

•  Maintenance - Dentists check sealants during routine exams and recommend touch-ups if needed.

•  Signs of Wear - If you notice chipping or roughness, consult your dentist for evaluation.

•  Longevity Tips - Brushing, flossing, and limiting sugary snacks help maintain effectiveness.

Keeping up with routine dental visits ensures your sealants remain intact and continue to protect your teeth.



Dental Sealants vs. Fluoride Treatments



Both sealants and fluoride treatments are powerful tools for non-invasive cavity prevention, but they serve different purposes.

•  Sealants - Create a physical barrier over the molars to block bacteria and food particles.

•  Fluoride - Strengthens tooth enamel, making it more resistant to decay across all tooth surfaces.

•  Combined Use - Using both treatments together provides comprehensive oral health protection.

•  Application Areas - Sealants are typically for molars, while fluoride is applied to all teeth.

Together, these treatments offer a proactive and well-rounded approach to preventative dental care for kids and adults alike.



Are Dental Sealants Covered by Insurance?



Insurance coverage for dental sealants often depends on age and specific plan details. Many policies include sealants for children up to a certain age, making them an affordable preventive option.

•  Children's Coverage - Frequently covered under preventive dental benefits.

•  Adult Coverage - Varies by provider and may require verification.

•  Cost-Effective - Less expensive than fillings or restorative treatments.

•  Long-Term Value - One-time investment that can prevent future dental work.

We recommend contacting our office to learn more about your coverage for sealants dental insurance through your provider.
