Brushing and flossing are the foundations of good oral health — but even the best daily routines can miss tiny grooves and pits on the chewing surfaces of teeth. That’s where dental sealants come in.
Sealants act as a protective barrier, shielding teeth from bacteria and acids that cause decay. While they’re most often recommended for children, adults can benefit from them too. Here’s how this simple, painless treatment helps prevent cavities for smiles of all ages.
What Are Dental Sealants?
Dental sealants are thin, protective coatings made of resin that your dentist applies to the chewing surfaces of the back teeth (molars and premolars). These teeth have deep grooves that are hard to clean with a toothbrush alone — especially for kids.
Once applied, the sealant bonds to the tooth’s surface, filling in those small crevices to prevent food and bacteria from settling in.
How Do Dental Sealants Prevent Cavities?
Sealants protect teeth in several key ways:
- They block bacteria and food particles. The coating seals out debris that can lead to decay, keeping the surface smooth and easy to clean.
- They make brushing more effective. With fewer crevices to trap plaque, brushing can remove more buildup and reduce the risk of cavities.
- They stop decay before it starts. Sealants act as an early defense system — once applied, they can prevent up to 80% of cavities in molars within the first two years.
- They’re safe and invisible. Sealants are clear or tooth-colored, so they blend naturally with your smile.
Sealants Aren’t Just for Kids
While most people associate sealants with children, adults can benefit too — especially those prone to cavities or with deep grooves in their teeth.
Adults who haven’t had cavities or fillings in their molars are often good candidates for sealants, and the process is quick, affordable, and completely non-invasive.
What to Expect During the Procedure
Getting dental sealants is fast and completely painless. Here’s what typically happens during your visit:
- Cleaning and drying the tooth Your dentist or hygienist thoroughly cleans the surface to remove any debris.
- Preparing the tooth A mild solution is applied to help the sealant bond securely.
- Applying the sealant The liquid coating is brushed onto the tooth and then hardened using a special curing light.
The entire process takes only a few minutes per tooth and provides long-lasting protection.
How Long Do Sealants Last?
Sealants can last up to 10 years with proper care, though your dentist will check them at each visit to ensure they remain intact. If a sealant becomes worn or chipped, it can be quickly repaired or replaced.
