How Fissure Seals Protect Teeth
Fissure seals might not be the flashiest dental treatment, but they’re a quiet achiever in protecting your teeth.
If you’ve ever wondered why your dentist recommends them for you or your child, it’s because fissure seals do a great job of preventing cavities in areas most vulnerable to decay.
They’re simple, pain-free, and can make a big difference in oral health.
What Exactly Are Fissure Seals?
Fissure seals, or dental sealants, are thin coatings made from a tooth-coloured resin. They’re applied to the grooves—or fissures—on your rear teeth chewing surfaces, typically the molars and premolars.
These grooves are natural pits in your teeth where food particles and plaque might readily become stuck, making them prime spots for decay.
Even with excellent brushing and flossing, these narrow grooves can be hard to clean properly. That’s where fissure seals step in—they act as a physical barrier, stopping bacteria and food particles from settling in.
Why Are Back Teeth So Vulnerable?
If you’ve ever felt like your back teeth get more attention from your dentist than the others, there’s a good reason. Molars and premolars have more complex surfaces than front teeth. Their grooves and ridges are essential for grinding food but also create hiding spots for plaque.
These areas are especially tricky for children and teens still learning proper brushing techniques. That’s why fissure seals are often recommended as soon as the adult molars come through—typically around ages 6 and 12.
But fissure seals aren’t just for kids. Adults with deep grooves or a history of decay in those areas can also benefit from their protection.
What’s the Process Like?
Getting fissure seals is surprisingly quick and painless.
No drilling, no needles—just a few easy steps:
- Cleaning the Tooth – Your Gordon dentist will thoroughly clean the tooth to ensure no plaque or debris.
- Preparing the Surface – A unique gel is briefly applied to the surface to aid in the sealant’s adhesion.
- Applying the Sealant – The fissure seal is painted onto the tooth’s grooves.
- Hardening It – A curing light hardens the sealant in seconds.
That’s it. You’re good to go immediately afterwards; the whole thing usually takes just a few minutes per tooth.
How Long Do Fissure Seals Last?
Fissure seals can last several years—sometimes up to a decade—depending on your bite and oral habits. You can wear them down more quickly by grinding your teeth or chewing on hard foods, but your Gordon dentist will check them during routine check-ups and reapply them if needed.
The beauty of fissure seals is that they offer long-term protection with minimal maintenance. You do not often find something simple and effective regarding dental care.
Real Protection for Real Life
Here’s the thing: no one likes dealing with cavities. They’re uncomfortable, which can lead to more serious issues. Let’s be honest—no one enjoys the cost or the drill.
Fissure seals are one of the easiest ways to avoid all of that. Think of them like a raincoat for your teeth.
Just like you’d wear one to stay dry in a storm, sealants keep out the elements—plaque, bacteria, and sugar—before they have a chance to do damage. And while brushing, flossing, and a healthy diet are still key, fissure seals add that extra layer of defence.
If you’ve got kids, this is especially valuable. Baby teeth might be temporary, but they still matter. As adult molars come in, starting early with fissure seals can set the stage for strong, cavity-free teeth well into adulthood.
Are Fissure Seals Right for You?
If you or your child has deep grooves in your molars, a history of dental decay, or struggles with keeping those back teeth clean, fissure seals are worth considering. They’re a small investment that can save you from much trouble.
You don’t have to wait for a cavity to show up before taking action. That’s the whole point—prevent it before it begins.
