As parents, you do your best to help your child brush and floss. But even with great daily habits, it’s common for kids to miss the back teeth—those deep grooves and chewing surfaces are especially hard to reach. That’s where dental sealants come in. They’re a simple way to help protect your child’s teeth during the years when they’re most vulnerable to cavities.
What Are Dental Sealants?
Dental sealants are thin, protective coatings that are applied to the chewing surfaces of the back teeth (molars and premolars). These teeth have natural pits and grooves that can trap food and bacteria, making them more susceptible to decay, especially in children who are still learning proper brushing techniques.
How Do Sealants Protect Teeth?
Sealants act as a physical barrier. Once applied, they help “seal out” plaque and food particles from settling into the grooves of the teeth. That makes it much harder for cavities to form in those hard-to-clean areas.
It’s not a substitute for brushing, flossing, or regular cleanings, but it’s an added layer of protection that can make a big difference, especially when paired with other preventive strategies.
Dental Sealants for Kids
Is it okay to put sealants on kids’ teeth? Yes, sealants are commonly recommended for children, and they’ve been proven safe and effective. In fact, both the Canadian Dental Association (CDA) and Health Canada recognize the benefits of sealants for cavity prevention in children.
Most dentists suggest placing sealants on a child’s molars shortly after they erupt, typically around ages 6 and 12. The earlier those grooves are protected, the less likely it is for bacteria and plaque to cause damage.
Sealants provide an easy, preventive option that can help reduce the risk of cavities during the years kids are most prone to decay.
Why Prevention Is Important
Preventing a cavity is always better than treating one. Cavities can cause discomfort, disrupt eating and sleeping, and sometimes require fillings or further dental care. For children, especially, preventing decay means fewer appointments, less dental anxiety, and more confidence in their smile.
The Application Process
There’s no special preparation required on your part. When sealants are recommended, your child’s dentist or hygienist will explain the process and let you know what to expect.
Applying sealants is a quick and straightforward part of a routine dental appointment. The dentist will make sure the tooth surface is clean and dry before applying the sealant material. Once in place, it’s set using a special light.
Your child can eat and drink normally after their appointment, and there’s no downtime.
How Long Do Sealants Last?
Sealants are designed to last for several years. While they’re durable, they aren’t permanent, and your dentist will check them during regular appointments to ensure they’re still intact.
Over time, normal chewing can wear down sealants. If a sealant becomes worn or comes off, it can usually be replaced. The important part is that they offer protection during the years when kids are at the highest risk of developing cavities in their molars.
Your child’s dentist will monitor their sealants during their check-ups and recommend reapplication when needed.
Other Ways to Prevent Cavities Alongside Sealants
Sealants are just one part of a broader approach to protecting your child’s smile. Here are a few other simple habits and services that help reduce the risk of cavities:
- Regular dental exams and cleanings: Typically, kids benefit from seeing the dentist every 6 months. These visits allow your dental team to remove plaque and monitor for early signs of decay.
- Brushing and flossing: Encouraging twice-daily brushing with fluoride toothpaste and daily flossing is still the foundation of good oral hygiene.
- Balanced nutrition: Sugary snacks and drinks can increase the risk of cavities. A balanced diet with plenty of water helps support strong teeth.
- Fluoride treatments: In some cases, your child’s dentist may recommend a fluoride treatment during their visit. Fluoride strengthens tooth enamel and helps prevent decay.
- Technology-driven care: Digital X-rays and modern diagnostics help catch small issues early, sometimes before they’re visible to the naked eye.
Every child’s needs are different, and your dental team will tailor their preventive care to suit your child’s unique smile.
