What Is a Dental Crown? Procedure, Types, Costs, and When You Need One
Crowns are commonly used in modern dentistry to protect teeth that have undergone significant damage, root canal treatment, or large fillings that can no longer support the tooth structure.
Quick answer: What is a dental crown?
A dental crown is a tooth-shaped cap placed over a damaged or weakened tooth to restore its function and appearance. It covers the entire visible portion of the tooth above the gumline and acts as a protective layer. The procedure usually takes two appointments, and the cost depends on the material and the complexity of the tooth.
Dentists commonly recommend crowns for:
- Large cavities
- Broken or cracked teeth
- Teeth that have had root canal treatment
- Severely worn teeth
- Cosmetic smile improvements
Why might you need a dental crown?
Crowns are used when a tooth is too damaged for a simple filling but still has enough structure to be restored.
A dentist may recommend a crown if you have:
- A large cavity that weakens the tooth
- A cracked or fractured tooth
- A tooth with root canal treatment
- A tooth worn down by grinding
- A misshapen or discoloured tooth
A crown helps strengthen and stabilise the remaining tooth structure. It can also change the look of a tooth, which is why crowns feature in both restorative and cosmetic dentistry treatment plans.
Dental crown vs filling: what is the difference?
A filling repairs part of a tooth, while a crown covers the whole tooth.
Filling
- Used for small to moderate cavities
- Less invasive and usually a shorter appointment
- May not be enough for a heavily damaged tooth
Crown
- Covers the entire tooth
- Gives more reinforcement for large damage or cracks
- Needs more preparation and usually two visits
Your dentist will recommend the right option based on how much of the tooth is affected.
What are the dental crown procedure steps?
A crown procedure follows five steps, usually across two visits.
- Examination and diagnosis. Your dentist uses X-rays to check for decay, cracks, and root health. Root canal treatment may be needed first if the inside of the tooth is damaged.
- Tooth preparation. The damaged portion is removed and the remaining tooth is reshaped so the crown fits securely.
- Impression or digital scan. The laboratory uses this to make a crown that matches your bite and surrounding teeth.
- Temporary crown. A temporary crown may be placed to protect the tooth while the final crown is made.
- Final crown placement. The permanent crown is bonded with dental cement, and your dentist checks the fit and bite.
What are the different types of dental crowns?
The main crown types are porcelain, porcelain fused to metal, zirconia, and metal. Each suits different teeth, appearance goals, and budgets.
Porcelain crowns
Often chosen for front teeth. Colour matched to surrounding teeth for a natural look.
Porcelain fused to metal crowns
A metal base with a porcelain outer layer. Often used on back teeth.
Zirconia crowns
A strong ceramic material with a natural look. Commonly used on molars.
Metal crowns
Very hard-wearing, but metallic in colour. Often used on back teeth where appearance is less of a priority.

How much does a dental crown cost in Australia?
Dental crown cost in Australia depends on the crown material, the condition of the tooth, and whether extra treatment such as a root canal or build-up is needed. Laboratory fees and the clinic also play a part.
For a full breakdown of what influences the fee, read our guide to dental crown price in Australia. For a figure specific to your tooth, book a consultation and ask for a written treatment plan.
How long do dental crowns last?
Most crowns last 10 to 15 years, and lifespan depends on oral care and bite habits.
Factors that influence how long a crown lasts:
- Oral hygiene habits
- Teeth grinding
- Diet and chewing habits
- Regular dental check-ups
Healthdirect Australia notes that crowns can help extend the life of a damaged tooth.

- Restores chewing function
