A dental crown is a custom-made restoration that sits over a tooth. It helps the tooth function and cope with everyday use. A dentist may suggest a crown when a tooth has lost strength due to damage, repeated fillings, or wear. The decision depends on how much healthy tooth structure remains and how the tooth functions as part of your bite.
Fillings repair parts of a tooth. A crown, by contrast, supports most of the tooth above the gumline. This can help the tooth handle chewing forces more evenly during activities such as eating and speaking.

What Does a Dental Crown Actually Do?
Dentists may recommend a crown when a tooth needs more support than a filling can provide. The aim is to protect what remains of the tooth and help it function comfortably over time.
By covering the tooth, a crown can help spread biting pressure across a wider surface. This reduces stress on weaker areas and supports everyday chewing.
“When we recommend a crown, we’re usually thinking about how to protect what’s left of the tooth and help it cope with daily chewing, rather than trying to make it look perfect,” said Dr Minal Ramekar from No Gaps Dental Artarmon clinic.
Back teeth usually take on stronger chewing forces, which is why dentists often consider crowns for molars. Front teeth may also benefit from crowns in certain situations, depending on strength needs and appearance.
When Might a Dentist Recommend a Dental Crown?
A dental crown is not always the first option, so best to speak to your dentist to understand your treatment options. Dentists usually recommend crowns when other treatments may not provide enough support.
Common situations include:
After root canal treatment, particularly for back teeth that may be more prone to fracture:
- A tooth that is cracked, broken, or significantly worn
- A tooth with a large filling and limited remaining structure
- A chipped tooth where strength needs to be restored
- A tooth that has lost its shape over time
Not every damaged tooth needs a crown. Dentists assess remaining tooth structure, bite forces, and overall oral health before recommending treatment.
In everyday practice, dentists also consider how a patient uses their teeth, such as chewing patterns or grinding habits, when deciding whether a crown is appropriate.

How Does a Dental Crown Work?
A dental crown covers and protects the tooth. It forms a new outer surface that works with your bite and surrounding teeth.
Once fitted, the natural tooth underneath remains in place and continues to support the crown. Ongoing dental care remains important, as a crown cannot remove all risk of future wear or decay.
What Are Dental Crowns Made Of?
Dental crowns can be made from different materials. The most suitable option depends on the tooth’s position, the forces placed on it, and individual needs.
Ceramic crowns are often used for front teeth because they can closely match natural tooth colour. Zirconia crowns are known for their strength and are commonly considered for back teeth. Porcelain-fused-to-metal crowns combine a metal base with a tooth-coloured outer layer, while metal or alloy crowns may be recommended where strength is a priority.
Your dentist will recommend a crown material based on your specific circumstances, not appearance alone. Speak to your dentist today about your treatment needs.

What Does a Crown on a Tooth Look Like?
Modern dental crowns are designed to blend with natural teeth. Dentists match the colour, shape, and size to suit your smile and bite.
The final appearance can vary depending on the tooth’s position, the crown material, and your natural tooth shape and colour.
“Once a crown is fitted and your bite settles, it usually blends in far more naturally than people expect,” said Dr Minal Ramekar from No Gaps Dental Artarmon clinic.
Are Dental Crowns Good for Your Teeth?
When recommended appropriately, dental crowns can help preserve remaining tooth structure.
A crown does not strengthen a tooth from the inside. Instead, it supports the remaining tooth and may help reduce the risk of further damage during normal chewing. A tooth with a crown can still develop decay at the edges, which is why good oral hygiene and regular dental check-ups remain essential.
How Long Does a Dental Crown Last?
Dental crowns are made to withstand regular use. How long they last varies from person to person.
Factors such as daily oral hygiene, tooth position, grinding or clenching habits, and regular dental reviews all play a role. Many crowns last for years with proper care, but they may eventually need review or replacement.
What About Dental Crown Costs?
The cost of a dental crown varies depending on several factors. These include the material used, the complexity of treatment, whether additional procedures are needed, and your private health insurance cover.
Discuss the dental needs with your dentist. After assessing your treatment needs, your dentist can provide a written treatment plan and cost estimate before you decide to proceed. Costs, rebates, and any no-gap eligibility depend on your treatment needs, health fund, and level of cover.
Caring for a Dental Crown
Caring for a crown is similar to caring for natural teeth. This includes brushing twice daily with fluoride toothpaste, cleaning between teeth daily, avoiding very hard objects such as ice, and attending regular dental check-ups.
After getting a dental crown, you might experience:
- Sensitivity: Your tooth may be sensitive to hot or cold temperatures, sweet or sour tastes, or pressure.
- Discomfort: Mild pain or discomfort when biting or chewing is normal.
- Gough feeling: Your tongue might feel the crown is uneven or rough.
- Numbness: Temporary numbness around the tooth and gums due to anaesthetic.
These effects usually subside within a few days. If you experience severe pain, swelling, or bleeding, contact your dentist ASAP.
To minimize discomfort:
- Avoid chewing on the crowned tooth until numbness wears off
- Eat soft foods
- Use desensitizing toothpaste if needed
- Follow your dentist’s aftercare instructions
If you grind or clench your teeth, your dentist may discuss ways to help protect your crown.
Thinking About a Dental Crown?
If you have been advised that you may need a dental crown, the next step is a personalised dental assessment. A dentist can explain your options and confirm whether a crown is suitable for your tooth.
Important Information
All dental procedures carry risks. A clinical assessment is required to determine whether a dental crown is suitable for your individual circumstances. Speak with your dentist or book an appointment to find out if a dental crown is right for you.
