Dental Fillings: Types, Cost and What to Expect

Dental fillings are one of the most common dental treatments in Australia. If you have a cavity or tooth decay, a filling restores the function, structure, and appearance of your tooth. Understanding the types of dental fillings, how they differ, their lifespan, and cost will help you make an informed decision with your dentist.

At Dentists on Vincent Leederville, we provide high-quality restorations to help you maintain a healthy and confident smile.

What Are Dental Fillings?

A dental filling is a material used to restore a tooth damaged by decay, wear, or minor fractures. When bacteria erode your enamel and create a cavity, a filling stops the decay from spreading, strengthens the tooth, and prevents further damage.

When You Might Need a Filling

A filling may be a suggestion of your dentist when you have:

• Pain in the teeth or being sensitive to hot, cold, or sweet foods.
• Visible holes or pits in your teeth
• Discolouration in a tooth
• Minor chipping or fracture

How Your Dentist Decides

The choice of filling depends on multiple factors:

• Size and location of the cavity
• Your oral habits (e.g., teeth grinding)
• Aesthetic preferences
• Cost considerations

Types of Dental Fillings

There are several types of dental fillings available, each with unique benefits. Here’s a detailed look at the most common options in Australia.

Filling Type	Material	Lifespan	Pros	Cons
Composite (Tooth-Coloured)	Resin + fine glass	5–10 years	Matches tooth colour, minimal drilling, suitable for front/back teeth	Less durable than amalgam for large cavities
Amalgam (Silver)	Silver, tin, copper, mercury	10–15 years	Durable, long-lasting, cost-effective	Visible, metallic, not aesthetic for front teeth
Ceramic / Porcelain	Porcelain	10–15 years	Stain-resistant, natural appearance	More expensive, requires lab work
Glass Ionomer	Acrylic + glass	5–7 years	Releases fluoride, good for root fillings and children	Less durable, prone to wear

 

Composite vs Amalgam Filling

Many patients ask whether to choose composite or amalgam.

• Composite is tooth-coloured and ideal for visible teeth but may wear faster.
• Amalgam is stronger for large chewing surfaces, but it is noticeable in appearance.

The Filling Procedure

Getting a dental filling is usually quick and straightforward, typically taking 30–60 minutes per tooth. Here’s what to expect:

1. Numbing the Tooth – Your dentist applies a local anesthetic so you won’t feel pain.
2. Removing Decay – The rotten part of the tooth is skillfully removed with the help of dental instruments.
3. Cleaning & Preparation – The cavity is cleaned and shaped to hold the filling securely.
4. Filling Placement – The chosen material (composite, amalgam, etc.) is inserted and shaped.
5. Shaping & Polishing – The filling is smoothed to suit your bite and polished to a natural appearance.

Dentists often use tooth-coloured composite fillings for a seamless appearance on both front and back teeth.

How Long Do Dental Fillings Last?

The durability of a dental filling depends on:

• Material used: Composite fillings last 5–10 years; amalgam lasts 10–15 years.
• Size & location of the cavity: Large back teeth fillings may wear faster.
• Oral habits: Teeth grinding or chewing hard foods can reduce lifespan.
• Diet & hygiene: Sugary foods, acid, and poor oral care may shorten durability.

Regular dental check-ups help detect early wear or damage so your filling can be repaired before it becomes a bigger problem.

Dental Filling Cost in Australia

Filling costs vary based on material, size, and tooth location. While exact prices depend on your dentist and clinic, here are the main factors:

• Size of the cavity – Larger cavities need more material and time.
• Filling material – Amalgam is typically the cheapest, composite is mid-range, and ceramic/porcelain is the most expensive.
• Tooth location – Back teeth may cost more due to the complexity of access.
• Health fund coverage – Some dental insurance plans cover part of the cost; check your policy.

The Australian Health Practitioner Regulation Agency (AHPRA) notes that fees vary by practice, but most dental clinics provide item numbers for health funds. Your dentist can give a detailed estimate during the consultation.

What to Expect After a Filling

After the procedure:

• Numbness – Usually wears off in a few hours.
• Sensitivity – Mild sensitivity to temperature or pressure is normal for a few days.
• Eating – Avoid hard, sticky foods until numbness subsides and the filling sets.
• Call your dentist if you experience persistent pain, swelling, or if the filling feels high or rough.

When Should a Filling Be Replaced?

A filling may need replacement if you notice:

• Pain or persistent sensitivity
• Visible cracks, chips, or rough edges
• Dark margins around the filling
• Worn-down surfaces

Regular dental exams help your dentist catch issues early and maintain the longevity of your fillings.

Frequently Asked Questions (FAQ)

Do fillings hurt?

Modern fillings are virtually painless due to local anesthesia. Some mild sensitivity may occur afterwards.

White vs silver fillings – which is better?

Composite (white) fillings look natural and are ideal for visible teeth. Amalgam (silver) fillings are stronger for large chewing surfaces.

Can a filling fall out?

Yes, fillings can become loose or fall out, especially with wear, decay under the filling, or trauma. See your dentist promptly.

Filling vs crown – when is a crown needed?

Crowns are used for severely damaged teeth. Fillings are best for minor to moderate decay.

How many visits are required?

Most fillings are completed in a single visit, depending on the size and location of the cavity.
