Dental Crowns: Types, Procedure and How Long They Last

A cracked tooth, a failed filling, a root canal — these are the moments when a dental crown becomes the most practical solution on the table. Crowns aren’t just a cosmetic fix.

They’re a structural one. And for many patients across Cabramatta, getting one is what keeps a compromised tooth functional for years to come.

If you’ve been told you need a crown — or you’re simply trying to understand what’s involved — this guide covers everything: what crowns are, the types available, how the procedure works, how long they last, and what affects the cost.

What Is a Dental Crown?

It is a custom-made cap that covers a damaged or weakened tooth. Once placed, it encases the visible part of the tooth above the gum line, helping restore its function and appearance. Crowns are designed to blend with the colour and shape of your natural teeth.

When Is a Crown Recommended?

It is recommended that a tooth be extracted when it is too damaged for a filling, but it can be adequately restored and is still worth saving. Common reasons include:

• After a root canal treatment, Root canal-treated teeth become more brittle over time. Crowns strengthen the tooth and reduce the risk of fracture during biting.
• Large or failing fillings — When a filling covers more than half the tooth, or an existing filling breaks down, a crown provides better structural coverage.
• Cracked or fractured teeth — A crack that extends deep into a tooth can worsen without protection. By covering the tooth, a crown holds it together and prevents further cracking.
• Severely worn teeth — Teeth worn down from grinding (bruxism) or acid erosion may need crowns to restore their original height and function.
• Dental implants — A crown is placed on top of an implant to serve as the visible, functional tooth.
• Cosmetic reasons — In some cases, crowns are used to reshape or cover teeth that are significantly misshapen or discoloured, where other options aren’t suitable.

 

Types of Dental Crowns

The right material depends on where the tooth sits, your bite, your preferences, and your budget.

Porcelain and Ceramic Crowns

Porcelain crowns are made entirely from dental porcelain and closely match the translucency of natural teeth, making them a common choice for front teeth. Ceramic crowns — including modern zirconia-based options — offer similar aesthetics and are metal-free. Both are a good fit for patients with metal sensitivities.

Pros: Highly aesthetic, metal-free, biocompatible

Cons: May not suit teeth under extreme biting pressure without reinforcement

Porcelain-Fused-to-Metal (PFM) Crowns

These crowns consist of a metal framework topped with porcelain. They’ve been used reliably in dentistry for decades and are often selected for back teeth where durability is a priority.

Pros: Strong, durable, reasonable aesthetics

Cons: A dark line near the gum line can appear if gums recede over time

Zirconia Crowns

Zirconia has become one of the most widely used crown materials due to its exceptional strength, making it suitable for both front and back teeth.

Pros: Very strong, highly aesthetic, metal-free, good longevity

Cons: Its hardness can put additional wear on opposing teeth if the bite isn’t carefully adjusted

The Crown Procedure: What to Expect

A dental crown typically requires two appointments.

First Appointment: Preparation

The tooth is numbed with local anaesthetic. Your Cabramatta dentist reshapes it by removing a small, precise amount of enamel from the sides and top — this creates room for the crown to sit naturally without affecting your bite.

The process involves taking an impression or digital scan, which is sent to a dental lab for crown fabrication. A temporary crown is then fitted while you wait, usually for one to two weeks.

Second Appointment: Fitting

The permanent crown is tried in after the temporary crown is removed, checked for fit, shape, and colour, and then cemented in place. Adjustments are made so your bite feels natural.

Some temperature sensitivity in the days following is normal and typically settles on its own.

How Long Do Dental Crowns Last?

With proper care, most crowns remain functional for 10 to 15 years, and many last considerably longer. Longevity depends on several key factors:

• Oral hygiene — Crowns don’t decay, but the tooth underneath can. Keeping up with twice-daily brushing and flossing around the crown margin helps protect the area and reduce the risk of decay beneath it.
• Grinding and clenching — Patients who grind at night put significantly more force on crowns than normal function requires. A custom night guard can reduce this wear.
• Diet and habits — Chewing on hard objects or using your teeth to open packaging puts unnecessary stress on crowns and can lead to chipping or loosening.
• Regular check-ups — Routine dental examinations allow your dentist to monitor the crown, the underlying tooth, and the surrounding gum tissue. Early detection of any issue makes it easier to address.

Cost Factors

Dental crown costs vary depending on a range of clinical and practical factors. Your dentist will provide a written treatment plan with fees before any procedure begins.

• Material — Different crown materials carry different laboratory fabrication costs.
• Complexity — A straightforward crown differs from one placed after root canal therapy or on a tooth requiring a build-up before the crown can be fitted.
• Number of appointments — Most cases require two visits, but complex situations may need additional preparation or review.
• Location of the tooth — Front teeth often involve more aesthetic consideration and time than back teeth.
• Health fund rebates — A portion of the cost may be claimable, depending on your insurance cover. Check your policy before treatment — reception can help you understand what your fund covers.

Frequently Asked Questions About Dental Crowns

Does getting a dental crown hurt?

The preparation is done under local anaesthetic, so you shouldn’t feel pain during the procedure. Some sensitivity and mild soreness in the days following are normal. If discomfort persists beyond a week, contact your dentist.

Can a dental crown fall off?

It’s uncommon, but it can happen — usually due to decay under the crown, a failed cement seal, or physical trauma. Should your crown become dislodged, store it safely and contact your dental practice promptly. In many cases, it can be re-cemented.

Do I need a crown after a root canal?

Not always, but for most back teeth, yes. After root canal treatment, teeth can become more vulnerable to breakage, so a crown is often used to support long-term function.

How do I care for a crown?

Treat it like a natural tooth — brush two times daily, floss carefully around the crown margin, and avoid habits that put excessive force on it.

Is a dental crown the same as a veneer?

No. A veneer covers only the front surface of a tooth and is primarily cosmetic. Crowns encase the full tooth and are placed when the tooth needs structural restoration.
