What’s the difference between a crown and an onlay?

A crown covers the entire visible part of your tooth, like a cap. It’s the right call when there isn’t enough strong, healthy tooth structure left to support anything smaller — often after a large filling has failed, a significant crack, or extensive decay.

An onlay covers less. It restores the chewing surface and one or more of the cusps (the pointy bits on top of your back teeth) while leaving more of your natural tooth in place. Think of it as sitting somewhere between a filling and a full crown — more coverage than a filling, less than a crown.

Neither option is “better” across the board. They solve different problems — which is exactly why, as a Brisbane CBD dentist offering both dental crowns and onlays, we assess each tooth individually rather than defaulting to the bigger treatment.

How we decide which one your tooth needs

A few things guide the decision, and we’ll always talk you through what we’re seeing before recommending either:

• How much healthy tooth structure remains. The more of your own tooth we can keep and still get a strong result, the more likely an onlay is suitable.
• Where the tooth sits and the bite forces on it. Back teeth carry more chewing load, which affects what will hold up long-term.
• Whether there’s a crack extending below the gumline. This can change the whole plan, sometimes ruling out an onlay.
• What’s happening cosmetically, particularly for teeth that show when you smile or talk.

We base this on your x-rays, a close clinical look, and sometimes photos taken during the appointment — not a one-size-fits-all rule.

What to expect either way

The process is similar for both. We prepare the tooth, take a scan or impression, and fit a temporary restoration while your crown or onlay is made. Most people find the appointment straightforward, and we’ll always explain what to expect for your tooth specifically before we start.

Both crowns and onlays are designed to last many years with good care and regular check-ups — how long depends on your bite, your oral hygiene, and the tooth itself, so we won’t put a number on it without seeing your case. If you’d like more detail on the process and what’s involved, our Complete Guide to Dental Crowns covers costs, benefits and what to expect in more depth.

A few common questions

Is an onlay cheaper than a crown? It depends — onlays typically use less material and less chair time, though the exact cost depends on your tooth and situation. We’ll give you a clear, written quote before any treatment begins.

Can I choose whether I have a crown or an onlay? Not always. It comes down to how much healthy tooth is left, so it’s a clinical decision rather than a preference — but we’ll always explain why we’re recommending one over the other.

Do onlays need replacing sooner than crowns? Not necessarily. With good care, both can last many years. An onlay is a more conservative treatment, not a shorter-lived one.

If you’ve damaged or weakened a tooth, your dentist may recommend a dental crown to restore its strength and appearance. At Dentistry on George, we help patients every week who need crowns for broken teeth, large fillings, or cosmetic reasons.

This guide explains everything you need to know — from the procedure and costs to what to expect during treatment.

What Is a Dental Crown?

A dental crown is a custom-made “cap” that fits over a damaged or weakened tooth, restoring its shape, size, and function while protecting what’s underneath.

Crowns can be made from different materials including porcelain, ceramic, zirconia, or metal. We’ll recommend the best option based on your needs, budget, and the location of the tooth.

When Do You Need a Dental Crown?

You may need a dental crown if you have:

• A tooth weakened by a large filling

• A cracked or broken tooth

• Severe tooth decay that cannot be restored with a simple filling

• A tooth that has had root canal treatment

• A dental implant that requires a crown on top

• Cosmetic concerns such as discoloured or misshapen teeth

Crowns are one of the most versatile treatments in modern dentistry and are often used in smile makeovers alongside veneers and bridges.

The Dental Crown Procedure

Getting a crown usually involves two appointments:

1. Tooth preparation – The damaged tooth is reshaped, and 3D scans are taken. A temporary crown is placed to protect the tooth while the scans are sent to our local Brisbane lab. Our crowns are made by a local lab technician using quality materials and are done to a very high standard.

2. Final crown placement – Once your custom crown is ready, it is fitted and cemented in place by our Brisbane CBD dentist.

Benefits of Dental Crowns

• Restore strength and function to weak teeth

• Protect against further damage or fracture

• Improve appearance with natural-looking materials

• Long-lasting solution (often 10–15 years with proper care)

• Can be combined with other treatments such as dental implants or bridges

Costs of Dental Crowns in Brisbane

The cost of a dental crown in Brisbane depends on the material chosen and the complexity of the treatment. While porcelain and ceramic crowns are popular for their natural look, zirconia crowns provide extra durability.

As a guide, dental crowns at our Brisbane CBD practice start from approximately start from approximately $1,800 for an onlay (partial crown), up to $2,650 for an implant crown Your dentist will provide a clear written quote before any treatment begins, so there are no surprises.

Porcelain or ceramic crowns — more natural appearance, ideal for front teeth

Zirconia or metal crowns — stronger, often used for back teeth

Dental Crowns vs. Other Options

If you’re deciding on the best treatment, you may also want to compare crowns with:

• Veneers – better for cosmetic improvements on front teeth only

• Fillings – suitable for smaller repairs but not large fractures

• Dental implants – used to replace missing teeth, often with a crown attached (but can be a bridge or denture)

Your dentist will guide you on whether a crown is the most suitable option or if another treatment may be better.

In Parts One and Two of our series, we explored why healthy gums matter and the difference between preventive and deep cleaning. Many patients wonder how to care for dental implants, bridges, veneers, or other cosmetic work during professional cleanings. At our Brisbane CBD dentist clinic, we take special care to maintain these areas while protecting your investment and supporting long-term gum health.

Why Special Care Is Needed

Dental implants, bridges, and veneers require extra attention because:

• Plaque and tartar can accumulate around them if not cleaned properly.

• Gum disease can affect both natural teeth and surrounding dental work.

• Improper cleaning can damage cosmetic surfaces or compromise implants.

Regular teeth cleaning in Brisbane ensures these areas are healthy and that your smile remains functional and attractive. Our dental professionals also ensure that they equip you with the knowledge and tools required to maintain your gum health and protect and advanced dentistry that you have.

Cleaning Around Implants

Dental implants are titanium posts that replace missing teeth, supporting crowns. While they don’t get cavities, the gums and bone around them still need protection:

• Professional cleaning removes plaque and bacteria around the implant.

• Special tools are used to avoid scratching the implant surface.

• Gum health is monitored to prevent peri-implantitis (inflammation around implants).

• Tailored advice is given to you to ensure you are cleaning around your implant correctly

Maintaining Bridges and Crowns

Bridges and crowns are excellent restorative options but can trap food and plaque underneath:

• Dentists carefully clean under bridges and around crowns.

• Polishing helps maintain a smooth surface, reducing bacterial buildup.

• Regular checkups ensure that the underlying teeth and gums stay healthy.

• Certain types of bridges may require the use of Superfloss and/or interdental brushes to clean all surfaces

Polishing Veneers and Cosmetic Work

Veneers, cosmetic fillings, and other aesthetic work require gentle cleaning:

• Only non-abrasive polishing is used to avoid scratching surfaces.

• Cosmetic dental work is checked for chips, discoloration, or gum recession.

• Regular cleaning preserves both your smile and the health of surrounding gums.

• Your dentist will recommend specific products for you to use (and avoid) to maintain your cosmetic dentistry.

Special Areas and Techniques

Certain areas need extra attention during professional cleanings:

• Hard-to-reach back teeth.

• Along the gumline.

• Around dental restorations.

At our Brisbane CBD dentist clinic, we tailor every cleaning to your individual needs, ensuring healthy gums and well-maintained dental work. We are also a big believer in educating you to care for your oral health at home, with tailored plans and recommendations of dental products as unique as you are.
