Even with diligent brushing and flossing, the deep grooves and pits on your back teeth (molars and premolars) can be difficult to clean. These areas are prime spots for food particles and bacteria to accumulate, leading to cavities. At Cosmo Smiles Dental, we offer a simple, effective solution to protect these vulnerable surfaces: dental sealants. This preventive treatment acts as a shield for your teeth, significantly reducing the risk of decay and helping you maintain a healthy smile for years to come.
What Are Dental Sealants and How Do They Work?
Dental sealants are thin, protective coatings made from a tooth-colored or clear plastic material. They are painted onto the chewing surfaces of the back teeth, where they bond into the depressions and grooves.
Once applied, the sealant creates a smooth, durable barrier that effectively “seals out” plaque, acid, and food particles. This prevents bacteria from settling into the hard-to-reach nooks and crannies of your molars, providing powerful protection against cavities. The application is quick, painless, and is one of the most effective preventive dental treatments available.
Key Benefits of Choosing Dental Sealants
Dental sealants are a cornerstone of preventive dentistry, offering significant advantages for patients of all ages.
- Effective Cavity Prevention: According to the American Dental Association (ADA), sealants can reduce the risk of decay in molars by nearly 80%. They provide a physical barrier that stops cavities before they can even start.
- Cost-Effective Solution: Preventing tooth decay with sealants is far less expensive and invasive than treating it with fillings, crowns, or root canals down the road. It’s a small investment that delivers major long-term savings.
- Painless and Quick Application: The process of applying sealants is non-invasive and completely painless. There is no drilling or discomfort involved, and it can be completed in just one short visit to our Arlington office.
- Long-Lasting Protection: With proper care and regular dental check-ups, sealants can protect your teeth for up to 10 years. We will monitor their condition during your routine visits to ensure they remain effective.

Who Can Benefit from Dental Sealants?
While often associated with pediatric dentistry, dental sealants offer valuable protection for both children and adults.
- Children and Teenagers: The most common time for decay to develop is during the cavity-prone years between ages 6 and 14. Applying sealants to permanent molars as soon as they erupt is a crucial step in protecting your child’s oral health.
- Adults: Any adult without decay or fillings in their molars can benefit from the extra layer of protection that sealants provide. This is especially true for those with deep grooves or a history of cavities.
The Simple Process for Applying Dental Sealants
Getting dental sealants at Cosmo Smiles Dental is a quick and straightforward procedure that can be completed in just a few minutes per tooth.
- Cleaning the Tooth: First, we will thoroughly clean and dry the surface of the tooth to be sealed.
- Preparing the Surface: An acidic gel is gently applied to the chewing surface for a few seconds. This microscopically etches the tooth, which helps the sealant form a strong bond.
- Rinsing and Drying: The tooth is then rinsed completely and dried again.
- Applying the Sealant: The liquid sealant material is carefully painted onto the grooves of the tooth.
- Curing the Sealant: A special curing light is used to harden the sealant, bonding it securely to the tooth in a matter of seconds.
And that’s it! Your tooth is now protected by a durable, invisible shield.
