Dental Fissure Sealants in Appin & Wollondilly
Fissure sealants are thin protective coatings painted into the deep grooves of your back teeth to seal them against decay. They're one of the simplest, most effective preventive treatments in dentistry, and research shows fissure sealing can reduce the risk of cavities in newly erupted molars by up to 80%.
Tooth fissure sealing is most commonly recommended for children's newly erupted permanent molars (around ages 6 to 7 and again at 11 to 13), but adults with deep grooves can benefit too. We bulk-bill dental fissure sealants under CDBS for eligible kids, so most families have no out-of-pocket cost.

What Are Fissure Sealants?
Fissure sealants (also called dental sealants, tooth sealants, or pit and fissure sealants in clinical contexts) are thin protective coatings applied to the chewing surfaces of back teeth, specifically the molars and premolars. The natural grooves on these teeth can be deeper than a toothbrush bristle, which means food and bacteria get trapped no matter how well you brush. Sealants fill and smooth these grooves to create a physical barrier that helps prevent cavities.
The sealant material we use is a tooth-coloured, biocompatible, TGA-approved resin or fluoride-releasing glass ionomer cement (depending on which is best clinically). Both bond securely to the enamel in a quick, painless, non-invasive procedure. While teeth fissure sealing is most often used for children's newly erupted molars, it's also a sensible step for adults whose grooves are vulnerable to decay. Sealants work best paired with a regular scale and clean and routine dental check-ups.
Benefits of Fissure Sealants
Fissure sealants are a small investment in time that pays off for years. Here's what they actually do:
Cuts cavity risk by up to 80% — Studies show fissure sealants reduce the risk of decay in sealed molars by up to 80%, particularly in the high-risk years just after a tooth erupts.
No needles, no drilling, no anaesthesia — The procedure is genuinely painless, which makes it one of the most child-friendly treatments in the practice.
Protects newly erupted teeth when they need it most — Children's molars are especially vulnerable in the first two years after they come through. Sealants give them an extra layer of defence at exactly the right time.
Saves you from bigger treatment later — A small sealant now is a fraction of the time and cost of a white filling, root canal, or extraction further down the track.
Some sealants release fluoride — Glass ionomer sealants slowly release fluoride into the surrounding enamel, adding ongoing decay protection over time. This complements your regular fluoride treatment appointments.
Who Benefits from Fissure Sealants?
Fissure sealants are a great option for anyone who wants to prevent tooth decay, but they're especially beneficial for specific groups. By applying sealants early, particularly on newly erupted permanent teeth, we can significantly reduce the risk of cavities and help maintain a healthy smile for years to come.
Children and Teenagers
They are the primary candidates for sealants. When a child's permanent molars and premolars erupt, the grooves on these new teeth are often deep and vulnerable to decay.
Individuals Prone to Cavities
People with a history of tooth decay or those who find it difficult to maintain perfect oral hygiene can greatly benefit from the extra protection sealants provide.
Adults with Deep Grooves
Some adults have naturally deep fissures and pits in their back teeth that are hard to clean, making them more likely to trap plaque and bacteria.
Patients Seeking Preventive Care
Sealants are an excellent choice for anyone who wants to take a proactive step in protecting their oral health and preventing future dental issues.
What to Expect During Your Fissure Sealant Appointment in Appin?
Tooth fissure sealing is one of the simplest treatments we do. There are no needles, no drilling, no anaesthesia, and the whole appointment is usually under 30 minutes. Here's exactly what happens in the chair:
We start by cleaning the back teeth so any plaque or food particles are removed and the surface is perfectly prepared. No drilling, just a gentle polish.
Using soft air and gentle suction, we dry the tooth surface. This step is what lets the sealant bond securely and last for years.
A mild etching gel is applied for a few seconds to roughen the enamel slightly so the sealant grips properly, then it's rinsed off. (This step exists to make the bond strong, not because anything's being removed.)
A thin liquid sealant is painted directly into the grooves and pits, where it flows in and creates a smooth, invisible barrier.
For resin sealants, a special light hardens the material in seconds. For glass ionomer sealants, the material sets chemically over a slightly longer period.
We check that the bite feels natural and that there are no rough edges. That's it. Your child can eat and drink straight away.
Aftercare and Maintenance: Caring for Your Fissure Sealants
At Appin Dental Surgery, our commitment to preventive care extends well beyond your visit. With a little maintenance, fissure sealants can protect your child's teeth for many years, especially during the cavity-prone growing years. With proper care, sealants can provide reliable, long-term protection against tooth decay for years to come. At Appin Dental Surgery, we are dedicated to helping families stay ahead of dental problems with proactive, prevention-first care. Here’s how to ensure the sealants continue to work their best:
Maintain Excellent Oral Hygiene
Remind your child to brush twice daily with fluoride toothpaste and to floss every night. Sealants protect the grooves, but the rest of the tooth still requires thorough cleaning.
Avoid Hard and Sticky Foods
Crunchy or sticky foods, such as ice and hard lollies, can chip or loosen the sealant. It’s best to enjoy these in moderation.
Keep Up with Regular Check-Ups
During routine dental visits, we will check the condition of the sealants. If one has chipped or worn down, we can easily repair or reapply it.
Let Us Know About Any Issues

FAQ
Fissure sealants are thin protective coatings painted into the deep grooves of your back teeth to seal them against decay. Research shows they reduce the risk of cavities in newly erupted molars by up to 80%. Book your child's check-up or call (02) 9068 1369.
Sealants are usually applied when permanent molars erupt, typically around age 6 to 7 for the first molars and age 11 to 13 for the second molars. Premolars with deep grooves may also benefit.
No. The procedure is non-invasive, with no needles, no drilling, and no anaesthesia. Most kids barely notice it's happening.
With good oral hygiene and regular check-ups, fissure sealants typically last 5 to 10 years. We check them at every routine appointment and reapply if one has chipped or worn down.
Yes. Sealants protect the grooves of back teeth, but daily brushing, flossing, and regular dental visits are still essential for the rest of the tooth and all the other teeth.
Yes, fissure sealants are safe and have been used in preventive dentistry for decades. The materials we use are TGA-approved and biocompatible, with negligible BPA traces (if any) well below safety thresholds, as confirmed by the ADA, WHO, and multiple systematic reviews.
Yes. Adults with deep grooves on their back teeth or a history of decay can benefit from sealants too. The procedure is exactly the same: no needles, no drilling, under 30 minutes.
Yes. Fissure sealants are covered under the Child Dental Benefits Schedule (item 161) for eligible children aged 2 to 17. We bulk-bill, so eligible families have no out-of-pocket cost.
They do different jobs. Fluoride strengthens all tooth surfaces against acid attack, while fissure sealants physically seal the deep grooves of back teeth where toothbrush bristles can't reach. The two work best together.
A single fissure sealant appointment usually takes less than 30 minutes, and sealants are often applied during a regular check-up so there's no need for a separate visit.
