Fissure Sealants for Children in Sandgate

Fissure sealants are a simple, painless way to help protect the deep grooves on your child’s back teeth from decay. At Sandgate Family Dental we offer sealants at routine check-ups when the timing and tooth surface are right. This page is written for parents thinking about whether sealants are worth it for their child.

If you would like us to take a look at your child’s teeth and discuss whether sealants are appropriate, you can book online.

What fissure sealants actually are

Permanent molars and premolars come through with deep grooves on their biting surface. Those grooves — called fissures — can be narrower than a single toothbrush bristle, which means even careful brushing struggles to reach inside them. Plaque and food get trapped, and decay starts in places that are hard to spot.

A fissure sealant is a thin, tooth-coloured resin that flows into those grooves and is hardened with a small blue light. It seals the surface so plaque cannot settle in, and so the tooth is easier to clean.

Why parents consider sealants

  • The first adult back teeth come through around age 6 — well before most children are good at brushing those areas thoroughly
  • Decay in a brand-new adult molar is disappointing when prevention is straightforward
  • The process is quick, painless, and does not require any drilling or numbing
  • Sealants reduce the risk of decay on the biting surfaces of treated teeth
  • Many children are eligible to have this funded through the CDBS

When sealants are usually placed

Sealants are most useful on teeth that have:

  • Just come through fully into the mouth
  • Deep, defined grooves
  • No existing decay or fillings on the biting surface

Typical timing windows:

  • First adult molars (six-year-old molars) — usually sealed between age 6 and 8
  • Premolars — usually sealed between age 10 and 12
  • Second adult molars (twelve-year-old molars) — usually sealed between age 12 and 14

We assess the depth of the grooves and your child’s decay risk before recommending sealants. Not every back tooth needs them — shallow grooves and very clean mouths often do well without.

How a sealant is placed

The visit is short and your child stays awake and comfortable throughout.

1. Cleaning the tooth

The tooth is cleaned and dried so the sealant can bond well to the enamel. There is no drilling and no anaesthetic needed.

2. Preparing the surface

A mild gel is applied to the biting surface for a few seconds to help the resin stick. This is rinsed off and the tooth is dried again.

3. Painting on the sealant

The dentist paints a thin layer of sealant into the grooves and hardens it with a small blue curing light. Each tooth takes only a minute or two.

4. Checking the bite

We check that the sealant feels comfortable when your child bites together and adjust if needed. Children can eat and drink straight away.

How long sealants last

Most sealants stay intact for several years. They can wear, chip, or come away over time — particularly in children who clench or grind, or chew hard objects. We check sealants at each routine check-up and top them up or replace them if needed.

Sealants are not a substitute for brushing

This part matters: sealants protect the grooves on the biting surface of back teeth. They do not protect the sides of teeth, the gum line, or the surfaces between teeth. Daily brushing twice a day, daily flossing where teeth touch, and good drink choices still do the heavy lifting in keeping decay away.

How this page relates to our preventive sealant page

If you would like a more general clinical description of sealants — including indications, materials, and adult applications — see our preventive dentistry fissure sealants page. The page you are reading now is written for parents specifically, with a focus on eligibility, timing, and CDBS coverage.

CDBS and payment

Fissure sealants are a covered item under the Child Dental Benefits Schedule (CDBS), which we bulk-bill at Sandgate for eligible children. Most school-aged children whose families receive certain government payments are eligible. See our CDBS bulk-billed children’s dental page for details and how to check eligibility.

We are also HICAPS providers. If your child is not eligible for the CDBS, sealants are usually covered under general dental on most policies; we can claim your eligible rebate at the practice on the day. The amount depends on your policy, level of cover, and annual limits.

Who sealants may suit

  • Children whose first adult molars have come through and have deep grooves
  • Children with higher decay risk — frequent snacking, dry mouth, less reliable brushing
  • Children with a sibling or parent who has had decay in similar teeth
  • Children who would find a filling on a back tooth difficult to manage

Who they may not suit: children whose back teeth have not yet erupted enough, teeth that already have decay or large fillings, or children with very shallow grooves and excellent home care. We will tell you honestly which teeth are worth sealing and which are not.

Fissure sealant FAQs

Will my child feel anything?

No. There is no drilling, no anaesthetic, and no pain. Most children describe the visit as “easy”.

How long does each tooth take?

About one to two minutes per tooth. A typical sealant visit takes 10 to 15 minutes for several teeth.

How long do sealants last?

Often several years, depending on your child’s biting habits and diet. We check them at every check-up.

Can sealants be placed if there is already a small cavity?

Not usually. If decay has started, we generally recommend a small filling instead. We will explain what is needed.

What if a sealant chips or wears away?

We can repair or replace it. Children may not notice when this happens, which is why regular check-ups matter.

Is the sealant safe?

Yes. Modern dental sealants have been used safely for decades and contain only a very small amount of material.

Does the CDBS cover sealants?

Yes, for eligible children. See CDBS bulk-billed for what is included.
