Fissure Sealants for Kids: Do They Prevent Cavities?
Children’s teeth are especially vulnerable to decay — particularly the back molars, where food easily gets trapped. At Weston Creek Dental Care, our fissure sealants provide a simple, effective way to protect your child’s teeth from cavities. This painless treatment helps keep kids’ teeth healthy, strong, and cavity-free as they grow.

What Are Fissure Sealants?
Protective Shields for Molars
Fissure sealants are thin, tooth-coloured coatings applied to the chewing surfaces of back teeth — specifically molars and premolars. These teeth have deep grooves, called fissures, where bacteria and food particles often collect, making them difficult to clean with brushing alone.
How Sealants Prevent Cavities
By sealing these grooves, dental sealants act as a barrier, preventing bacteria and acids from reaching the enamel. This significantly lowers the risk of tooth decay, making it one of the most effective tools for cavity prevention in kids teeth.
A Quick and Painless Procedure
The application of fissure sealants is fast and comfortable. Each tooth takes just a few minutes, and no injections or drilling are required. This makes sealants a simple, stress-free addition to routine kids dentist visits.
When Should Kids Get Fissure Sealants?
Most children benefit from dental sealants when their first and second permanent molars emerge — typically around ages 6 and 12.
During regular check-ups, our kids dentist will assess whether a child’s molars have deep grooves or are prone to plaque build-up.
Sealants may also be applied to baby teeth for younger children who are at higher risk of decay.
The Benefits of Dental Sealants
Strong Cavity Protection
Fissure sealants protect the most vulnerable teeth, often for 5–10 years.
Cost-Effective Prevention
Preventing decay with sealants is far more affordable and less invasive than treating cavities later.
No Pain or Drilling
Children tolerate sealant applications easily, and there is no need for anaesthesia.
Safe and Long-Lasting
Sealants are made from biocompatible, BPA-free materials that adhere safely to enamel and wear down naturally over time.
Step-by-Step Process of Applying Fissure Sealants
- Cleaning: The tooth is polished to remove plaque and debris.
- Preparation: The surface is etched with a safe gel to enhance bonding.
- Application: The
dental sealant is painted onto the molar.
- Curing: A special blue light hardens the sealant instantly.
- Check-up: The dentist ensures the bite feels normal and comfortable.
The procedure takes about 10–15 minutes and can often be completed during a regular kids check up.
Caring for Sealants After Application
Fissure sealants require minimal maintenance. Continue daily brushing and flossing, and follow these tips:
- Avoid chewing hard foods like ice or sticky candy
- Attend regular six-month dental check-ups
- Reapply sealants if they wear down
Our family dentist will monitor sealants during each visit to ensure continued protection.
