Crown or filling cost: what are you actually paying for?

If you have been told you need a crown, one of the first questions is usually what it will cost, and why the fee for a crown is so different from the fee for a filling. Those are fair questions. The honest answer is that the fee depends on your individual tooth, so the most useful thing we can give you is not a single figure but a personalised written treatment plan, with item numbers you can check with your health fund before anything starts. Here Dr Andrew explains what you are actually paying for, how health funds usually treat crowns and fillings, and how to read a quote and check your rebate.

Why there is no honest single figure

How much does a crown cost in Australia? It is one of the most common things people search, and it is natural to want a number. The difficulty is that no two teeth are the same. The fee for a filling, a BioClear restoration or a crown depends on:

• The individual tooth: how much of it is damaged or already filled, and how much sound tooth remains.
• Complexity: where the tooth sits, how it meets the teeth around it, and the forces of your bite.
• Clinical time: careful work on a heavily restored tooth takes longer than a small repair.
• Materials: different restorations use different materials.
• Direct or indirect: whether the restoration is made directly in the tooth in one visit, or made outside the mouth and then bonded or cemented in place.

Often the full picture only becomes clear once an old filling is out and we can see what is left underneath. Our guide to a big old filling that has broken explains why what remains decides the next step. A figure given without seeing the tooth would not be honest, so we do not give one over the phone. What we do give you, once we have examined the tooth, is a written plan.

What you are actually paying for

Why is a crown so expensive? Patients ask us this, and the same question comes up about any larger restoration. It helps to look past the label, "a filling" or "a crown", to what actually goes into the work. Take a BioClear restoration as an example. As our patient guide puts it, this is not simply "a big filling". It is a precise, comprehensive restoration designed to preserve, protect and strengthen the tooth you already have. What goes into it:

• Preservation: less unnecessary removal of sound natural tooth structure.
• Protection: bonded coverage designed to support weakened walls and vulnerable cusps.
• Precision: time-intensive isolation, matrixing, bonding, injection moulding, finishing and bite refinement.
• Experience: advanced planning and execution by a clinician experienced in the BioClear technique.
• Future options: a conservative first step that may be maintainable or repairable, and avoids moving to a crown before it is needed.

The same thinking applies to a crown. You are paying for clinical time, precision and planning, the materials, and, for a crown made outside the mouth, the work of designing and making it before it is fitted to your tooth.

How much of your own tooth is kept matters too. Studies have measured that preparing a tooth for a full crown removes roughly 63 to 72% of the tooth structure above the gum. Once that tooth structure is gone, it cannot be put back, so we think about the long-term pathway for the tooth, not just the next appointment. Our guide to why crowns fail explains how long crowns usually last and why some need attention over the years.

That is why we start with the same question for every tooth: "What is the least invasive treatment that will properly protect this tooth?" Our recommendation is based on your tooth, not a default procedure. When a tooth can be rebuilt rather than crowned, the aim is a better outcome, often for a similar fee, and in some cases considerably less, because we are keeping more of your own tooth rather than replacing it. Every tooth is different, and we always explain the fee before treatment. You can read more about this approach on our crown alternatives page.

A crown and a filling are different items doing different jobs

Why do a crown and a filling have different fees? Mostly because they do different jobs for the tooth. In one sentence: a traditional filling repairs the space; a BioClear restoration rebuilds and supports more of the tooth; a biomimetic crown provides broader protection when the remaining foundation is not enough. Our guide to crown or filling explains how we decide which one a tooth needs.

They are also different items on the dental schedule that dentists and health funds use in Australia. For example, a direct filling on a back tooth is an "adhesive restoration" item in the 531 to 535 range, while a full crown is a separate item such as 613, 615 or 618. A traditional filling is usually made directly in the tooth in a single visit. A crown is usually made outside the mouth, covers much more of the tooth, and involves more planning and more than one appointment. A biomimetic crown is also made outside the mouth, then bonded to the tooth. Because the work is different, the fees are worked out differently.

Is BioClear expensive?

Is BioClear expensive, and how much does a BioClear restoration (sometimes called a BioClear filling) cost per tooth? We are asked this often. The honest answer is that it depends on the tooth and the treatment planned: its complexity, the clinical time, the materials and whether the treatment is direct or indirect. We will explain your options and set out the fee and item numbers for your planned treatment in your written treatment plan before any treatment starts.

As our patient guide puts it, sometimes a more comprehensive restoration can reduce the cycle of repeated repairs, but every case must be considered individually.

Is a crown major dental?

Crowns are usually classed as major dental, and simple fillings as general (routine) dental; complex fillings can also count as major. This varies by fund and policy, so check your policy.

Healthdirect, the government-funded health information service, describes routine dental as possibly including x-rays, examinations, cleaning and polishing, fluoride treatment and simple fillings, and major dental as possibly including complex fillings, crowns, veneers, bridgework, implants and dentures. It also notes that funds use different terms to describe what they will pay for, so you will need to check your policy carefully. If you have private health insurance with extras cover, your policy documents or your fund can tell you how it treats each item.

Will my health fund cover a crown? Waiting periods and annual limits

Whether your fund pays towards a crown or a filling, and how much, depends on your level of cover, how your fund classifies the item, any waiting period and any annual limit. As Healthdirect puts it, policies vary widely between different health funds, and there may also be limits on how much you can claim each year.

Waiting periods are set by each fund. According to the Private Health Insurance Ombudsman, they generally range from about two to six months for general dental and can be 12 months or more for major items. If you have recently joined a fund or changed your level of cover, check your waiting periods before treatment starts.

How to read your treatment plan and check your rebate

Item numbers are the code for each part of your treatment that your fund uses to work out your rebate. The Australian Dental Association's policy on informed financial consent says dentists should give patients the relevant item numbers for each proposed service, so patients can confirm their health fund benefit or government rebate. That is why we give you a written treatment plan with the item numbers for each part of your treatment. Once you have it:

1. Look at each line. Each part of your treatment has its own item number and fee.
2. Contact your fund with the item numbers. Ask what rebate you would receive for each one, and whether a waiting period or annual limit applies.
3. Work out your out-of-pocket cost. This is the gap between the fee and your rebate.
4. Take your time. The ADA encourages patients to contact their fund and to be given time to consider the out-of-pocket costs before treatment begins. We would rather you feel sure than rushed.

One thing worth knowing: an estimate is not a guarantee. It can change if a procedure takes longer than expected or other treatment turns out to be needed, for example once an old filling is removed and we can see the tooth underneath. If that happens, we will talk it through with you.

Healthdirect also suggests three simple questions before you agree to dental treatment: ask how much the procedure will cost, ask for the item numbers, and ask whether you really need the procedure. It is completely reasonable to ask why a particular treatment is recommended.

Does Medicare cover crowns or fillings?

Most dental care is not covered by Medicare. The Child Dental Benefits Schedule helps eligible children with basic services such as check-ups and fillings, and covers some preformed crowns, but not laboratory-made crowns. For most adults, any rebate towards a crown or filling comes from private health insurance rather than Medicare.

Sometimes a crown is exactly what the tooth needs

Understanding the fees is not about steering anyone away from a crown. When there is not enough reliable tooth left, or the tooth needs broader protection from a heavy bite, a crown can be the right choice, and we will tell you so. The goal is to do no more than necessary, and no less than required to protect your tooth. If a crown is the right choice for your tooth, our crowns and bridges page explains what is involved.

Want a clear, written plan before you decide?

A second opinion appointment gives you a personalised written treatment plan with item numbers you can check with your fund before anything starts. At our Ipswich practice, we will look carefully at the tooth, show you what we see, and explain each suitable option and its fee, so you can make the decision that is right for you.
