Fissure Sealants

Simple, painless protection against tooth decay

Fissure sealants are a preventative dental treatment designed to protect the deep grooves in your back teeth (molars) from decay.
They’re especially beneficial for children and teenagers, but adults with deep grooves in their teeth can benefit too.

What are fissure sealants?

Back teeth have natural grooves and pits (called fissures) that can trap food and bacteria. These areas can be difficult to clean thoroughly with a toothbrush — even with good brushing habits — making them more vulnerable to cavities.

Fissure sealants are a thin, protective coating applied to these grooves to seal them off and create a smooth surface that’s easier to clean.

How do fissure sealants work?

The process is quick, non-invasive, and completely painless:

Cleaning the tooth: The tooth surface is cleaned and dried.
Preparing the surface: A special solution is applied to help the sealant stick.
Applying the sealant: The liquid sealant is painted onto the grooves
of the tooth.
Hardening: A curing light is used to harden the sealant in seconds.

Once applied, the sealant acts as a barrier against plaque and food particles.

Benefits of fissure sealants

Prevents decay in deep grooves where brushing can’t reach

Pain-free and needle-free — no drilling required
Quick application — usually takes just a few minutes per tooth
Long-lasting protection — can last up to 5–10 years with proper care
Cost-effective prevention compared to filling cavities later

Who should get fissure sealants?

Children and teens: Ideal when their adult molars first come through
(usually around ages 6 and 12)
Adults: Suitable for those with deep grooves or a history of decay
Anyone wanting to reduce their risk of cavities in hard-to-clean back teeth

Your dentist will examine your teeth and let you know if sealants are appropriate.

What to expect after treatment

There’s no downtime. You can eat and drink as normal right away. The sealants are not visible when you smile and don’t affect how your teeth feel or function.

We check your sealants during regular check-ups and reapply them if necessary.

Frequently Asked Questions

1. At what age should my child get fissure sealants?

Sealants are typically recommended when a child’s first and second adult molars come through — usually around ages 6 and 12. Applying
them early gives the best chance to prevent decay before it starts.

2. How long do fissure sealants last?

Sealants can last 5 to 10 years, depending on the patient’s oral habits and how well the teeth are cared for. We check them at every check-up and can easily reapply them if they wear down.

3. Do fissure sealants hurt?

No, applying sealants is completely pain-free. There’s no need for anaesthetic, drilling, or any invasive treatment — it’s simply a matter of cleaning and sealing the tooth surface.

4. Can adults get fissure sealants too?

Yes. While most commonly used for children, adults with deep grooves or a high risk of decay can benefit from sealants as well. Your dentist will advise if you’re a good candidate.

5. Can I still get cavities if I have sealants?

Sealants protect the chewing surface of the teeth, but they don’t cover the entire tooth, so good oral hygiene is still essential.
Brushing, flossing, and regular dental visits remain important for keeping your whole mouth healthy.
