Dental Sealants

Protecting Your Child’s Teeth from Cavities

Dental sealants are a simple and effective way to help prevent tooth decay. They’re usually applied to the chewing surfaces of back teeth (molars), where cavities are most likely to form. At our Brantford dental office, we offer sealants as a preventive treatment for children and teens.

Why Are Sealants Important?

Molars have deep grooves and pits—also called fissures—that are hard to clean with a toothbrush. These grooves can trap food and plaque, making it easier for bacteria to cause cavities. Since molars start coming in around age 6 and continue until about age 12, it can be tough for children to brush them properly. Sealants cover those grooves to create a smoother surface and protect against decay.

When Should Children Get Dental Sealants?

Sealants work best when applied as soon as the molars come in. This helps protect the teeth before any cavities have a chance to form. Most kids benefit from getting sealants between the ages of 6 and 12.

Types of Dental Sealants

• Glass ionomer sealants: These release fluoride over time, which helps strengthen teeth and prevent cavities. They’re also less sensitive to moisture, which is helpful when treating younger children. However, they may not last as long as other options.
• Resin-based sealants: These are more durable and can last 5 to 10 years or even longer. They don’t release fluoride but offer long-term protection by staying in place longer.

What to Expect During the Sealant Procedure

Getting dental sealants is quick, painless, and doesn’t require drilling. Here’s what happens:

1. The dentist cleans the chewing surface of the tooth.
2. A special gel is applied to roughen the surface so the sealant sticks better.
3. The tooth is rinsed and dried.
4. The sealant is painted onto the tooth and hardened using a curing light, if needed.

Keeping Sealants Working Well

Dental sealants are very effective at preventing cavities—as long as they stay intact. Your child’s dentist will check them during regular dental visits. If any wear or cracks are found, the sealant can be repaired or replaced.
