Tooth Fillings in Toowoomba: How Dentists Restore Cavities and Protect Teeth

Tooth decay is one of the most common dental conditions in Australia, affecting people of all ages. The good news? When caught early, a simple dental filling can restore your tooth, relieve discomfort, and stop decay in its tracks — often in a single appointment.

At Range Dental in Toowoomba, we use tooth-coloured composite resin and porcelain restorations to deliver fillings that look natural and feel great. Whether you're experiencing tooth sensitivity, a visible hole, or you've been told you have a cavity at your last check-up, this guide covers everything you need to know.

What Is a Dental Filling?

A dental filling is a restorative treatment used to repair a tooth damaged by decay, a minor crack, or wear. The dentist removes the decayed portion of the tooth, cleans the area thoroughly, and fills the cavity with a durable material to restore the tooth's original shape and function.

Without treatment, cavities don't heal on their own — they grow. A small filling left untreated can progress to a root canal, a crown, or eventually tooth loss. Treating decay early is always the least invasive and most cost-effective option.

Signs You Might Need a Filling

Many early cavities cause no pain at all, which is why regular dental check-ups are so important. When symptoms do appear, they may include:

• Tooth sensitivity to hot, cold, or sweet foods and drinks

• A visible dark spot, hole, or pit on the tooth surface

• Toothache or spontaneous pain, particularly when biting down

• Food consistently getting stuck in a particular tooth

• A rough or sharp edge you can feel with your tongue

💡 Tip: Sensitivity alone doesn't always mean decay — it can also be caused by gum recession or enamel erosion. The only way to know for sure is a dental examination and X-rays.

Types of Dental Fillings Available in Toowoomba

Not all fillings are equal. The right material depends on the size and location of the cavity, your bite, aesthetic preferences, and budget. Here's a comparison of the main options:

Filling Type	Appearance	Durability	Best For	Cost Range (AUS)
Composite Resin	Tooth-coloured	7–10 years	Front & back teeth	$150–$350 per surface
Porcelain Inlay/Onlay	Highly natural	10–20+ years	Larger cavities	$900–$1,800+
Amalgam (Silver)	Silver/grey	10–15 years	Back teeth (less common)	$100–$250 per surface
Gold	Gold	15–30 years	Posterior teeth	$1,200–$3,500+

Composite Resin (Tooth-Coloured) Fillings

This is the standard at Range Dental. Composite resin matches the natural colour of your teeth, bonds directly to the tooth structure, and requires less drilling than older amalgam techniques. It's suitable for both front and back teeth and is the most commonly chosen option for patients today.

Porcelain Inlays and Onlays

When a cavity is too large for a standard filling but doesn't quite warrant a crown, a porcelain inlay or onlay is an excellent middle-ground solution. These are custom-made restorations crafted in a laboratory to fit your tooth precisely. Porcelain inlays and onlays are the closest you can get to restoring a tooth to its original strength —

far superior to standard composite fillings for larger restorations.

Amalgam (Silver) Fillings

While less common in modern practice, amalgam fillings are highly durable and may still be recommended in certain circumstances, particularly for back teeth under heavy chewing pressure. Some patients also present with existing amalgam restorations that simply need monitoring or replacement.

What to Expect During Your Filling Appointment at Range Dental

Many people feel anxious about dental procedures, but a routine filling is one of the most straightforward treatments we perform. Here's what happens step by step:

• Initial Assessment: Your dentist will examine the tooth and take digital X-rays to determine the extent of the decay and the most appropriate treatment.

• Local Anaesthetic: The area around the tooth is numbed so you feel no pain during the procedure. You may feel some pressure, but the treatment should be entirely comfortable.

• Decay Removal: Using a dental drill or air abrasion, the decayed portion of the tooth is carefully removed. Composite fillings allow us to be very conservative — removing only what's necessary.

• Filling Placement: The composite resin is placed in layers, with each layer hardened using a special curing light. The filling is then shaped and polished to blend with your surrounding teeth.

• Bite Check: You'll bite down on a thin piece of articulating paper so your dentist can ensure the filling doesn't interfere with your natural bite. Minor adjustments are made on the spot.

Most single-tooth fillings are completed in 30–60 minutes. If you have multiple cavities, your dentist may recommend treating them across separate appointments.

Aftercare: How to Look After a New Filling

Composite resin fillings set immediately under the curing light, so you can eat and drink right after your appointment — though it's wise to avoid very hard or sticky foods for the first 24 hours while any residual sensitivity settles.

To protect your filling long-term:

• Brush twice daily with a fluoride toothpaste

• Floss once daily, especially around the filled tooth

• Avoid biting directly onto hard foods like ice, nuts, or hard lollies

• Wear a custom mouthguard if you grind your teeth at night (bruxism)

• Attend your regular 6-monthly check-ups so your dentist can monitor the restoration

⚠️ If you experience persistent pain or sensitivity more than a week after your filling, contact us — it may need a minor adjustment, or in rare cases, further treatment.

How Long Do Fillings Last?

The lifespan of a filling depends on the material, its size, where it sits in your mouth, and how well you maintain your oral hygiene. Generally:

• Composite resin: 7–10 years on average, though many last longer with good care.

• Porcelain inlays/onlays: 10–20+ years — the most durable tooth-coloured option.

• Amalgam: 10–15 years, though older amalgam fillings may begin to crack or leak over time.

Fillings don't last forever. Over time, the seal between the filling and the tooth can weaken, allowing bacteria to re-enter. Your dentist will check the condition of existing restorations at each routine visit.

When a Filling Isn't Enough

In some cases, decay has progressed too far for a filling to be the right solution. Your dentist may instead recommend:

• A dental crown: When more than half the tooth structure is affected, a crown provides full coverage and protection.

• Root canal treatment: If decay has reached the inner pulp of the tooth, a root canal removes the infected tissue before the tooth is sealed and crowned.

• Extraction and replacement: In severe cases, the tooth may not be salvageable. Modern tooth replacement options like dental implants can restore full function and appearance.

The best way to avoid these more complex treatments is to address decay early — which is exactly why regular dental check-ups matter so much.

Frequently Asked Questions About Tooth Fillings

Do dental fillings hurt?

The procedure itself should not hurt. Your dentist will apply local anaesthetic to numb the area before starting. You may feel some pressure or vibration, but pain during treatment is unusual. If you feel discomfort at any point, let your dentist know immediately.

How much does a filling cost in Toowoomba?

Costs vary depending on the size of the filling, the material used, and the number of tooth surfaces involved. Composite resin fillings typically range from $150–$350 per surface. Porcelain inlays and onlays cost more but offer superior longevity. Most private health funds with extras cover provide a rebate for fillings — check your level of cover before your appointment.

Can I eat after a filling?

Yes. Composite resin hardens immediately under the curing light, so you can eat right away. Avoid very hard or chewy foods for the first 24 hours, and wait until any numbness from the anaesthetic has fully worn off before eating to avoid accidentally biting your cheek or tongue.

Is it normal for a tooth to be sensitive after a filling?

Mild sensitivity to temperature for a few days after a filling is completely normal, especially with composite resin. This typically settles on its own. If sensitivity persists beyond 1–2 weeks or gets worse, contact your dentist — the bite may need adjusting, or the pulp may be inflamed.

How do I know if my old filling needs replacing?

Your dentist checks existing fillings at every routine exam. Signs it may be time to replace a filling include visible cracking, a rough edge you can feel, increased sensitivity around the tooth, or decay detected on X-ray around the filling margins.
