If you’re a parent, you already know the routine: brushing twice a day, reminding your child to floss, and getting to the dentist for regular checkups. Even with all that effort, cavities can still sneak in, especially on your child’s back teeth. That’s where dental sealants can make a big difference.
Dental sealants are thin, protective coatings that are applied to the chewing surfaces of molars. These teeth have deep grooves that easily trap food and bacteria, and even good brushing doesn’t always reach them. Sealants seal those grooves, helping to keep cavity-causing bacteria out.
Why are dental sealants recommended for kids?
Most cavities in children develop on the chewing surfaces of the back teeth. Sealants are designed to protect exactly those areas, making them a simple and effective way to prevent decay. Research shows that sealants can significantly reduce the risk of cavities in molars, especially during childhood and adolescence.
When should my child get sealants?
Dentists usually recommend sealants shortly after permanent molars come in:
- Around ages 6–7, when the first molars appear
- Around ages 11–14, when the second molars come in
In some cases, sealants may also be recommended for baby teeth, particularly if a child is at higher risk for cavities.
What is the process like?
The sealant procedure is quick, comfortable, and completely pain-free. The dentist or hygienist cleans the tooth, dries it, and applies the sealant, which is then hardened with a special light. No drilling, needles, or freezing are needed, and your child can eat normally right away.
Are dental sealants safe?
Yes. Dental sealants have been used safely for decades and are widely recommended by dental professionals in Canada. They’re well tolerated by children and provide an added layer of protection for developing smiles.
How long do sealants last?
Sealants can last several years and are checked at regular dental visits. If they wear down or chip over time, they can easily be repaired or replaced.
Protect your child’s teeth
Dental sealants are a simple, effective way to help protect your child’s teeth during the years when cavities are most likely to develop. Along with brushing, flossing, fluoride, and regular dental visits, sealants will ensure your child’s dental hygiene is protected.
