Tooth Filling Cost Breakdown: Factors That Influence What You Pay

by Pearl Dental Care Team | Jul 2, 2025

If you have been told you need a tooth filling, you might wonder about the cost and procedure. Understanding the tooth filling cost in Australia, the different types of filling materials, and what to expect can help you make proper decisions about your dental care. In this detailed guide, we will walk you through everything you need to know, all explained in a warm, professional, and easy-to-follow tone.

So, How Much Does a Tooth Filling Cost in Australia?

The starting cost of a tooth filling in Australia typically begins from around $150 AUD for a small, simple filling. However, the actual cost often varies depending on several factors, such as the filling material chosen, the cavity’s size, the affected tooth’s location, and the dentist’s expertise.

It is also important to remember that if you have private health insurance that covers basic dental services, you may be reimbursed for at least a portion of the cost.

What Is a Dental Filling and Why Does Your Tooth Need One?

A dental filling is a simple but powerful way to repair a tooth damaged by decay, cracks, or everyday wear. It is a common dental procedure in which a dentist carefully removes a tooth’s decayed or damaged portion and fills the space with a special filling material. This process restores the tooth’s shape, strength, and function while also protecting it from further decay.

You might need a tooth filling if you have:

• Cavities caused by acid-producing bacteria that erode your tooth enamel
• Cracked teeth from injury or biting down on something hard
• Teeth that have become worn over time due to habits such as grinding or biting nails

Without timely treatment, even a small cavity can grow larger, eventually leading to severe damage that may require a root canal, dental crowns, or even tooth extraction. Getting a filling early helps preserve your natural tooth, maintain the health of the surrounding teeth, and avoid more complex dental procedures down the track.

In short, tooth fillings are not just about fixing what is broken. They are about saving your smile, protecting your oral health, and preventing bigger (and more expensive) problems later on.

Why Do You Need a Tooth Filling?

Without timely treatment, a small cavity can lead to more serious problems, such as severe decay, infections, or even the need for a root canal or dental crown. Getting a filling helps safeguard the natural tooth structure, maintain the strength of the surrounding teeth, and preserve your natural teeth for as long as possible.

Choosing the Right Filling Material: What Are Your Options?

The chosen filling material is major in the final appearance, durability, and overall filling cost. Let us take a closer look at the most common filling materials used:

Composite Fillings (Tooth Coloured)

• Made from a blend of composite resin and fine glass particles.
• Designed to mimic your tooth colour for a natural look.
• Ideal for front teeth or visible areas.
• Starting cost: around $150 AUD.

Composite fillings attach securely to the tooth, helping to retain more of its natural structure.

Amalgam Fillings

• It is made from a blend of metals, including silver, mercury, and tin.
• Known for their strength and durability.
• It is commonly used for back teeth where chewing pressure is high.
• Starting cost: around $120 AUD.

While amalgam fillings are long-lasting, they are silver in colour and less aesthetically pleasing than tooth-coloured options.

Gold Fillings

• Crafted from a gold alloy.
• It is highly durable and can remain intact for several decades.
• Higher in cost due to material expense and labour intensity.
• Starting cost: approximately $600 AUD or more.

Gold fillings offer outstanding strength but are more noticeable than other options.

Porcelain Fillings (Ceramic Fillings)

• Custom-made to match your natural tooth colour.
• Very strong and resistant to staining.
• Often used for large cavities or cosmetic restorations.
• Starting cost: from around $800 AUD.

Porcelain fillings (sometimes called ceramic fillings) provide a beautiful, natural finish but are more expensive.

Glass Ionomer Fillings

• Made from a combination of glass and acrylic.
• Releases fluoride to help prevent decay.
• Best suited for areas not under heavy chewing pressure.
• Starting cost: approximately $150 AUD.

Glass ionomer fillings are commonly used for fillings near the gum line or for temporary restorations.

What Can Affect the Cost of Your Tooth Filling?

When it comes to tooth filling costs, you might notice that prices can vary quite a bit from one patient to another. That is because several important factors come into play when working out the final cost. Understanding these factors can give you clearer insight into what you are paying for and the reasons behind the cost.

Here are the key things that can influence the cost of your dental filling:

1. Size and Complexity of the Filling

Smaller cavities are quicker and easier to fill, which usually means a lower cost. Larger or more complex medium-sized fillings may require more work and more material, making them a bit pricier.

2. Type of Filling Material Used

The chosen filling material has a big impact on the price. For example:

• Composite fillings and glass ionomer fillings are affordable and natural-looking.
• Amalgam fillings tend to be less expensive but are silver in colour.
• Porcelain fillings and gold fillings offer excellent durability but come at a higher price.

Choosing the right filling material often depends on the tooth’s location, your budget, and your cosmetic preferences.

3. Location of the Affected Tooth

Fillings on front teeth can be simpler than those on molars, with stronger chewing forces. Molars might require more durable material and extra shaping to match your natural bite, which can increase the cost.

4. Dentist’s Experience and Expertise

A highly experienced dental professional might charge more, but they also bring greater skill and precision to the filling procedure. Choosing an experienced provider helps ensure the best long-term result for your natural teeth.

5. Geographical Location of the Dental Practice

Where you live matters too; dental fees can vary depending on whether the dental practice is in a major city, a suburban area, or a regional town.

6. Health Insurance Coverage

If you have private health insurance that includes basic dental services, it might cover at least a portion of your dental filling costs. Be sure to check the details of your insurance policy, including limits and waiting periods.

7. The Condition of the Tooth

The more damaged the affected tooth is, the more complex the tooth-filling dental procedure becomes. If decay is extensive or if the tooth’s structure needs rebuilding, additional work may be required, adding to the overall cost.

What to Expect During the Tooth Filling Dental Procedure

Understanding the filling procedure can ease any nerves you might have about the appointment. Here’s a quick breakdown:

1. Local anaesthetic is administered to numb the area around the affected tooth.
2. The dentist removes the decayed portion using a dental drill or laser.
3. The prepared cavity is cleaned thoroughly to prevent infection.
4. The filling material is placed into the cavity and shaped to match the tooth’s shape and bite.
5. Once in place, the material is hardened, often with a special light.
6. The dentist smooths and polishes the filling to create an even surface.

In many cases, all of this can be completed in a single dental appointment.

How to Take Care of Your Dental Fillings

With proper care, your tooth fillings can last for many years. Here are some tips to maintain them:

• Practise good oral hygiene: Brush and floss daily.
• Visit your dental professional regularly for check-ups and cleans.
• Avoid biting hard objects (like ice or pens).
• Limit sugary foods to help prevent decay.
• Be cautious with cold foods if you notice sensitivity after the filling.
• Report any cracks, discomfort, or roughness to your dentist immediately.

When Might You Need a Replacement?

Although fillings are strong, they do not last forever. You may eventually need a replacement if:

• The filling becomes cracked or chipped.
• There is new tooth decay around the filling.
• The filling wears down due to chewing forces.

Your dentist will track the condition of your tooth fillings during routine appointments.

Does Health Insurance Cover Dental Fillings?

If you have private health insurance that covers basic dental services, it may help cover part of the dental filling cost. Many dental practices are BUPA and NIB preferred providers, and most accept all private health insurance funds.

For eligible families, some practices also bulk bill through the government-funded Child Dental Benefits Schedule (CDBS), making it easier for children to access important dental treatments like tooth fillings.

It is always a good idea to check your insurance policy to understand what is covered, any waiting periods that may apply, and how much you can claim for your dental procedures.

What Are Your Options If a Traditional Filling Is Not Enough?

In some cases, if the damage to the tooth is extensive, other treatment options might be recommended instead of a simple filling:

• Dental crowns, to cover and protect a weakened tooth.
• Root canal treatment, if decay has extended to the pulp.
• Onlays or inlays are made from porcelain or composite materials.

Your dentist will recommend the most suitable option based on how much damage the tooth has sustained.

Why Taking Action Early Can Save Your Smile

Delaying a filling can turn a simple problem into a complicated one. Small cavities are quicker, easier, and cheaper to treat. Left untreated, they can lead to:

• Extensive tooth damage.
• Higher costs due to complex dental procedures.
• Loss of the natural tooth.

Early action saves your tooth structure, maintains a healthier mouth, and avoids more extensive interventions later.

Final Thoughts: Your Smile Is Worth Protecting

While the tooth filling cost might seem like an unwelcome expense, think of it as an investment in your oral health and overall wellbeing. Whether you opt for composite fillings, amalgam fillings, gold fillings, or porcelain fillings, restoring the integrity of your natural teeth prevents bigger problems down the road.

Maintaining good oral hygiene, attending regular check-ups, and discussing treatment options with your dental professional will ensure your teeth remain strong, healthy, and beautiful for years to come.
