Dental Sealants for Kids: A Simple Way to Prevent Cavities



An Easy Solution for Young Smiles

Children are especially prone to tooth decay, particularly on the chewing surfaces of their molars. At Marinaside Dental in Vancouver, we often recommend dental sealants as a simple, painless, and effective way to protect your child’s teeth.

Sealants are one of the easiest preventive treatments for kids — helping to keep their smiles healthy and cavity-free as they grow.

What Are Dental Sealants?  

Dental sealants are thin, protective coatings made of a safe resin material.
They are applied to the deep grooves (pits and fissures) of the back teeth, where toothbrush bristles often can’t reach.

Sealants work by:

  • Creating a smooth, easy-to-clean surface on the molars
  • Blocking food and bacteria from settling in deep grooves
  • Providing long-lasting protection against cavities

Studies show that dental sealants can reduce cavities in children’s permanent molars by up to 80%.

Why Kids Benefit the Most

At Marinaside Dental Vancouver, we typically place sealants as soon as a child’s permanent molars erupt — usually around ages 6 and 12.

Since children are still developing consistent brushing and flossing habits, sealants give them a valuable extra layer of protection during these early years.

Sealants are especially helpful for kids who:

  • Have deep grooves in their molars
  • Experience frequent cavities
  • Are still learning proper brushing techniques

The Sealant Application Process

Applying dental sealants is quick, painless, and non-invasive. Here’s what to expect during your child’s visit:

1. The tooth is cleaned and dried.
2. A gentle bonding material is applied to help the sealant adhere.
3. The sealant is painted onto the tooth’s surface and hardened with a curing light.

The entire process takes only a few minutes per tooth, but the protection can last for many years with good oral hygiene.

Start Early with Prevention

Prevention is always better than treatment — especially for young smiles.
At Marinaside Dental Yaletown, we focus on early, preventive care to help your child avoid cavities and build lifelong healthy habits.

Ask your dentist about dental sealants during your child’s next check-up. It’s a quick, affordable way to protect their teeth and confidence for years to come.
