Dental Sealants for Children: One of the Best Ways to Help Prevent Cavities
Did you know that cavities are one of the most common chronic childhood diseases?
Even children who brush well can develop cavities, especially on the chewing surfaces of their back teeth where deep grooves easily trap food and bacteria.
At Bronte Road Family Dental in Oakville, we focus on preventing cavities before they start. One of the most effective preventive treatments for many children is the use of dental sealants.
What Are Dental Sealants?
Dental sealants are thin protective coatings placed over the chewing surfaces of molars and premolars.
They seal the deep grooves where toothbrush bristles often cannot reach, helping prevent food, plaque, and bacteria from collecting in these hard-to-clean areas.
Sealants do not replace brushing or flossing—they simply provide an extra layer of protection.
Why Do Children Get Cavities So Easily?
Children’s back teeth naturally contain tiny pits and grooves.
These grooves can:
- Trap food particles.
- Hold bacteria.
- Be difficult to clean thoroughly.
- Increase the risk of tooth decay.
Even children with excellent brushing habits may not be able to clean these deep grooves completely.
When Should Sealants Be Applied?
Dental sealants are most effective shortly after the permanent molars erupt.
For many children, this means:
- Around 6 years of age for the first permanent molars.
- Around 12 years of age for the second permanent molars.
Your dentist will recommend the best timing based on your child’s individual dental development and cavity risk.
How Are Dental Sealants Applied?
Applying sealants is simple, comfortable, and completely painless.
The procedure usually takes only a few minutes per tooth.
The process includes:
- Cleaning the tooth.
- Preparing the chewing surface.
- Applying the liquid sealant.
- Hardening the material with a special curing light.
No drilling and no freezing are usually required.
How Long Do Sealants Last?
With proper care, dental sealants can protect teeth for many years.
During routine dental checkups, your dentist will examine the sealants to make sure they remain intact.
If necessary, they can often be repaired or replaced quickly.
Do Sealants Replace Brushing?
No.
Sealants only protect the chewing surfaces.
Children still need to:
- Brush twice daily with fluoride toothpaste.
- Floss every day.
- Limit sugary snacks and drinks.
- Visit the dentist regularly.
Good oral hygiene remains the foundation of cavity prevention.
Are Dental Sealants Safe?
Yes.
Dental sealants have been used safely for decades and are supported by major dental organizations as an effective way to reduce cavities in children at increased risk of tooth decay.

Frequently Asked Questions
Do sealants hurt?
No. Applying dental sealants is painless and usually requires no freezing or drilling.
Which teeth receive sealants?
Sealants are most commonly placed on the permanent molars because these teeth have the deepest grooves and are at the highest risk of cavities.
How long do sealants last?
Many sealants last several years with proper care. Your dentist will check them during regular examinations.
Can adults get dental sealants?
Yes. Some adults with deep grooves and a high risk of cavities may also benefit from sealants.
Are sealants better than fluoride?
They work differently. Fluoride strengthens enamel throughout the mouth, while sealants physically protect the deep grooves on chewing surfaces. For many children, both treatments are recommended together.
Preventing Cavities Is Easier Than Treating Them
Dental sealants are one of the simplest and most effective ways to reduce the risk of cavities in children’s permanent molars.
Combined with regular brushing, fluoride, healthy eating habits, and routine dental visits, sealants can help protect your child’s smile for years to come.
If you’d like to find out whether your child is a good candidate for dental sealants, the team at Bronte Road Family Dental in Oakville would be happy to help.
