Dental Filling Cost Explained: Prices by Material and Tooth Type

How Much Does a Dental Filling Cost in Australia?

The dental filling cost in Australia typically ranges from $150 to $450 per tooth, depending on the filling material used, the tooth being treated, and how extensive the decay or damage is. In some cases, premium options such as porcelain restorations can cost more, particularly when a tooth requires additional strength or long-term durability.

This article explains how much a dental filling costs in Australia, breaks down the types of dental fillings and their cost, and explores what affects dental filling cost so you can make an informed decision. We’ll also look at pricing differences between front teeth and molars, whether a dental filling is worth the cost, and how Australian patients can reduce out-of-pocket expenses.

If you’re considering treatment, understanding these factors can help you plan ahead and avoid unexpected surprises.

Quick Answers: Dental Filling Cost

How much does a dental filling cost in Australia?
Most fillings cost between $150 and $450 per tooth. Larger or more complex restorations may cost more.

What’s the cheapest filling option?
Amalgam (silver) fillings are usually the most affordable.

What’s the most natural-looking filling?
Composite (white) fillings blend with natural teeth and are the most popular choice.

Is a dental filling worth the cost?
Yes. Early fillings prevent more expensive treatments like root canals or crowns.

What Affects Dental Filling Cost?

Dental filling costs vary because every tooth and every patient is different. Several clinical and practical factors influence the final price.

Key Factors That Influence Dental Filling Cost

• Filling material selected
• Size and depth of the cavity
• Number of tooth surfaces involved
• Tooth location (front teeth vs back teeth)
• Complexity of the procedure
• Time required for treatment
• Whether an old filling needs replacement

Quick summary:
Larger cavities, back teeth, and stronger or more aesthetic materials generally increase dental filling cost.

Types of Dental Fillings and Their Cost

Choosing the right filling material is one of the biggest cost considerations. Below is a breakdown of the most common options used in Australia.

Composite (White) Fillings

Average cost: $180–$450 per tooth

Composite fillings are tooth-coloured and designed to blend seamlessly with natural teeth.

Advantages

• Natural appearance
• Mercury-free
• Bonds directly to tooth structure
• Suitable for front and back teeth

Disadvantages

• May wear faster than amalgam on heavy-biting molars

Best for:
Small to medium cavities, visible teeth, patients prioritising aesthetics.

Amalgam (Silver) Fillings

Average cost: $150–$350 per tooth

Amalgam fillings are known for their strength and durability, particularly in back teeth.

Advantages

• Very strong
• Long-lasting
• Generally lower cost

Disadvantages

• Metallic appearance
• Less commonly used today due to aesthetic preferences

Best for:
Back molars where strength matters more than appearance.

Glass Ionomer Fillings

Average cost: $150–$300 per tooth

Glass ionomer fillings release fluoride and are often used in specific situations.

Advantages

• Fluoride release helps protect teeth
• Bonds well to enamel
• Useful for children’s teeth

Disadvantages

• Less durable
• Shorter lifespan than composite or amalgam

Best for:
Children, temporary fillings, low-load areas near the gumline.

Porcelain or Ceramic Fillings (Inlays and Onlays)

Average cost: $900–$2,000+ per tooth

These are custom-made restorations created outside the mouth and bonded to the tooth.

Advantages

• Excellent strength
• Highly aesthetic
• Long lifespan
• Resistant to staining

Disadvantages

• Higher upfront cost
• Often requires more than one appointment

Best for:
Large cavities or teeth needing long-term durability without a full crown.

Dental Filling Cost by Tooth Type

The tooth being treated plays a major role in pricing.

Front Teeth (Incisors and Canines)

Typical cost: $150–$350

Front teeth usually require smaller fillings and are easier to access.

Common materials

• Composite (white)

Why they cost less

• Less chewing pressure
• Simpler access
• Smaller restorations

Premolars

Typical cost: $180–$400

Premolars handle moderate chewing forces and often involve more than one surface.

Common materials

• Composite
• Amalgam (in some cases)

Molars (Back Teeth)

Typical cost: $250–$450+

Molars experience the most pressure during chewing and often require larger restorations.

Why molar fillings cost more

• Greater biting forces
• Harder to access
• Larger cavities
• More time and precision required

How Many Surfaces Are Being Filled?

Dentists often classify fillings by how many surfaces of the tooth are affected.

• One-surface filling: Lower cost
• Two-surface filling: Mid-range cost
• Three or more surfaces: Higher cost

The more surfaces involved, the more material and time are required.

Is Dental Filling Worth the Cost?

Short Answer: Almost Always, Yes

A filling is one of the most cost-effective dental treatments available. Treating decay early helps prevent:

• Tooth infections
• Root canal treatment
• Dental crowns
• Tooth loss and replacement

Cost Comparison (Australia)

Treatment	Typical Cost
Dental filling	$150–$450
Root canal treatment	$1,800–$3,500
Dental crown	$1,500–$2,500
Dental implant	$5,000–$7,000

Paying for a filling early almost always saves money in the long term.

What to Expect During a Dental Filling Appointment

Most dental fillings are completed in a single visit.

Step-by-Step Overview

1. Examination and X-rays (if required)
2. Local anaesthetic to numb the tooth
3. Removal of decay or damaged tooth structure
4. Placement of the filling material
5. Shaping, polishing, and bite adjustment

The procedure is generally quick, comfortable, and routine.

How Long Do Dental Fillings Last?

The lifespan of a filling depends on the material used, oral hygiene habits, and bite forces.

• Composite fillings: 5–7 years
• Amalgam fillings: 10–15 years
• Porcelain restorations: 15+ years

Regular check-ups help monitor fillings and extend their lifespan.

Can Health Insurance Reduce Dental Filling Cost?

Private Health Insurance

Many Australian health funds cover part of the cost of basic dental fillings under extras cover.

• Coverage typically ranges from 50%–80%
• Annual limits apply
• Waiting periods may apply

Child Dental Benefits Schedule (CDBS)

Eligible children may receive fillings under the CDBS, up to the program’s benefit cap.

How to Reduce Dental Filling Costs

• Attend regular dental check-ups
• Treat decay early
• Maintain good oral hygiene
• Use private health insurance effectively
• Ask about suitable material options

Preventive care is the most effective way to keep dental costs manageable.

At Southport Park Family Dental, many fillings are placed after early decay is detected during routine check-ups. Patients who attend regularly often require smaller, simpler fillings, while those who delay treatment are more likely to need larger restorations or additional procedures.

Dental materials used in Australia must meet strict safety and quality standards. This ensures that fillings are biocompatible, durable, and appropriate for long-term use.

Patients can feel confident knowing their treatment follows nationally recognised clinical and safety guidelines.
