Fissure Sealants in Midland

Protecting young teeth from decay

The back molar teeth have deep grooves called fissures, which can be difficult for children to clean properly. Food particles and bacteria can easily get trapped in these tiny grooves, increasing the risk of tooth decay.

At Helena Street Dental in Midland, we offer fissure sealants as a simple and effective way to protect children’s teeth and make brushing easier.

What are fissure sealants?

A fissure sealant is a thin, protective coating made from a tooth-coloured resin material.
It flows into the grooves on the chewing surfaces of the back teeth, sealing them off and preventing plaque, bacteria, and food from getting trapped.


Once hardened, the tooth surface becomes smoother and easier to keep clean.

Why are fissure sealants important for children?

Children’s molars are especially prone to cavities because:

• They have naturally deeper grooves than adult teeth
• Children often lack the dexterity to brush effectively
• Tooth enamel is still developing and more vulnerable to decay

Fissure sealants act as a protective barrier, reducing the likelihood of cavities forming in these areas during the early years.

What happens during the procedure?

Applying fissure sealants is quick, safe, and completely pain-free. The process usually takes only a few minutes per tooth:

1. The teeth are gently cleaned and dried.
2. The sealant material is painted into the grooves using a small brush.
3. A special curing light is used to harden the material.
4. Once set, the sealant forms a smooth surface that’s easier to brush and keep clean.

Children can eat and drink as normal immediately after treatment.

How long do fissure sealants last?

Fissure sealants are very durable and can last for several years.
During your child’s regular check-up, our team will examine the sealants to ensure they’re still intact and providing full protection. If any areas show wear, they can be easily repaired or replaced.

Are fissure sealants suitable for adults?

Yes — while sealants are most commonly applied to children’s teeth, they can also be beneficial for adults with deep grooves or a higher risk of decay. Your dentist will assess whether they’re appropriate for your needs during a check-up.
