When a tooth is damaged, broken, or weakened, a dental crown is one of the more common ways to restore it. A dental crown is a custom-made cap placed over the tooth, designed to protect what remains and help the tooth function again. For many people, the procedure feels unfamiliar before they have it, so understanding each step in advance makes a real difference.
Getting a dental crown is not a single event. It involves an assessment, tooth preparation, and fitting, across one or two appointments depending on the approach your dentist takes. Knowing what happens at each stage helps you arrive prepared, ask the right questions, and understand what to expect during recovery. Dental crowns and bridges are a well-established part of restorative dentistry, and the materials and techniques used today have become considerably more refined.
Quick Overview
- A dental crown is a tooth-shaped cap placed over a damaged or weakened tooth to restore its structure and function
- It may be recommended for broken, severely decayed, or root canal-treated teeth, as well as certain cosmetic situations
- The procedure typically involves tooth preparation, a digital scan or impression, a temporary crown, and a final fitting, though same-day options exist in some cases
- How long a crown lasts depends on the material used, where it is in the mouth, and how well it is cared for
- A dental assessment is the starting point; your dentist will review the tooth and discuss the most suitable material and approach
The sections below outline each stage of the procedure, the crown types available, what affects longevity, and how to care for a crown once it is placed.
What Is a Dental Crown and When Is One Needed?
A dental crown is a cap that covers the entire visible surface of a tooth above the gum line. It is cemented into place and, once fitted, functions as part of the natural bite.
A dentist may recommend a crown for a range of situations. Common reasons include a tooth that is broken, cracked, or badly decayed, a tooth that has undergone root canal treatment, a tooth with a very large filling where little natural structure remains, or a tooth that is misshapen or discoloured in a way that cannot be addressed with a simpler restoration.
Crowns can also be used to anchor a dental bridge, or as the visible cap on a dental implant. In each case, the goal is to protect what remains of the tooth while restoring its shape and function.
Not every damaged tooth requires a crown. Your dentist will assess the extent of the damage and discuss whether a crown is the most appropriate option, or whether a filling, inlay, or onlay might serve the same purpose with less tooth preparation.
What Types of Dental Crowns Are Available?
Dental crowns can be made from several materials, and the right choice depends on the tooth’s location, the forces it will face, and individual factors such as metal sensitivities or preference for a natural appearance.
The main types used in Australian dental practice include:
- Porcelain or ceramic crowns: Made entirely from tooth-coloured material, these are commonly used on front teeth where appearance matters most. They can be matched closely to surrounding teeth.
- Porcelain-fused-to-metal (PFM) crowns: These have a metal core with a porcelain exterior. They offer good strength alongside a natural look, though a thin dark line may become visible at the gum line over time.
- Zirconia crowns: Made from a high-strength ceramic, zirconia crowns are durable and tooth-coloured, making them suitable for both front and back teeth. They have become more widely used as milling technology has improved.
- Metal crowns (gold alloy): These are extremely durable and place minimal stress on opposing teeth. They are typically used on back molars where appearance is less of a concern.
Your dentist will discuss which material suits your situation. The tooth’s location, your bite, and the amount of remaining tooth structure all influence the recommendation.
What Does the Dental Crown Procedure Involve, Step by Step?
Most dental crown procedures take two appointments, spaced one to two weeks apart. In some clinics, same-day crowns are available using in-chair milling technology, which reduces the process to a single visit.
First appointment: assessment and tooth preparation
The dentist begins with an examination and X-rays to assess the condition of the tooth and its surrounding bone. If the tooth is severely decayed or infected, a root canal may need to be completed before the crown can be placed.
Once the tooth is ready, a local anaesthetic is applied to the area. The tooth is then shaped by removing a thin layer of enamel from the outer surface, creating enough room for the crown to fit without feeling bulky. The exact amount removed depends on the crown material: metal crowns require less reduction than all-ceramic options.
If a large portion of the tooth is missing due to decay or fracture, a core build-up using filling material may be placed first to give the crown a stable base.
A digital scan or traditional impression is then taken of the prepared tooth and the surrounding teeth. This is sent to a dental laboratory where the custom crown is fabricated. Before you leave, a temporary crown is cemented over the prepared tooth to protect it while the permanent one is being made.
Between appointments
The temporary crown is not as strong as the final restoration. It is worth being mindful of sticky or hard foods on that side of the mouth, and some sensitivity to temperature is normal during this period.
Second appointment: fitting the permanent crown
When the permanent crown is ready, the temporary one is removed. The dentist checks the fit, shape, and colour of the new crown against the surrounding teeth, and makes any adjustments needed. Once the fit is confirmed, the crown is cemented into place.
How Long Does a Dental Crown Last?
Crown longevity varies depending on the material used, the location of the tooth, and how well the crown is maintained. Individual outcomes differ, and no restoration lasts indefinitely.
Across more than 290 single-unit crowns placed at an Australian university dental clinic over a five-year period, the overall five-year survival rate was 83.9%, with location in the mouth, crown material, and patient factors all influencing outcomes. Crowns placed on premolars showed higher survival than those on molars, which face greater chewing forces.
Broader clinical data suggest that well-maintained crowns commonly last between 10 and 15 years, with some lasting considerably longer. The most frequent reasons for failure include loosening, chipping of the outer surface, decay at the crown margin, and fracture of the underlying tooth.
Teeth grinding (bruxism), biting on hard objects, and inconsistent home hygiene are among the factors most associated with shorter crown lifespan.
What Is the Connection Between Root Canal Treatment and Dental Crowns?
A crown is often recommended after root canal treatment, particularly for back teeth. Root canal therapy removes the nerve and blood supply from inside the tooth, which can make the remaining structure more brittle over time and more prone to fracture under biting forces.
Placing a crown over a root canal-treated tooth helps protect the remaining structure and reduces the risk of the tooth splitting. Front teeth with a root canal may not always require a crown, depending on how much natural tooth structure remains. Your dentist will advise based on the specific tooth and your bite.
Delaying a crown after root canal treatment is a common cause of tooth loss. Without protection, the treated tooth is more vulnerable to fracture, which can make it unrestorable.
How to Care for a Dental Crown
A crown does not decay, but the tooth structure underneath it can. The margin where the crown meets the tooth is a common site for plaque accumulation and decay if cleaning is not thorough.
Good daily care includes:
- Brushing twice a day with a soft-bristled toothbrush and fluoride toothpaste
- Flossing daily, paying attention to the gum line around the crowned tooth
- Attending regular dental check-ups so your dentist can assess the crown’s fit and the health of the surrounding gum tissue
- Avoiding chewing ice, biting fingernails, or using teeth as tools, all of which place excessive force on restorations
- Avoiding sticky foods that can dislodge a crown, especially in the weeks following placement
If you grind your teeth at night, a custom night guard is worth discussing with your dentist. Bruxism places significant stress on crowns and can cause chips, cracks, or loosening over time. A well-fitted night guard helps distribute the forces more evenly and protect the restoration.
If your crown feels loose, causes persistent sensitivity, or changes in how your bite feels, contact your dentist promptly. Early attention to a loose crown helps prevent decay of the tooth underneath.
A Considered Approach to Dental Crown Treatment
A dental crown procedure is a well-established way to restore a damaged tooth and protect it from further breakdown. The right material, careful preparation, and good home care all contribute to how long a crown lasts and how comfortable it feels over time. Individual outcomes vary, and a thorough assessment is the right place to start.

Frequently Asked Questions
How many appointments does a dental crown procedure take?
Most dental crown procedures involve two appointments spaced one to two weeks apart. The first is for tooth preparation, impressions or a digital scan, and placement of a temporary crown. The second is for fitting and cementing the permanent crown. In some clinics, same-day crown technology allows the process to be completed in a single visit.
Does getting a dental crown hurt?
The procedure is carried out under local anaesthetic, so discomfort during treatment is generally minimal. Some sensitivity around the prepared tooth and temporary crown is common between appointments, particularly to temperature. Once the permanent crown is placed and the area settles, this typically resolves. If sensitivity is significant or persistent, contact your dentist.
How long does a dental crown last?
With proper care, many crowns last between 10 and 15 years, and some last considerably longer. Longevity depends on the material used, the location of the tooth in the mouth, your bite, and how consistently the crown is cared for. Teeth grinding, poor oral hygiene, and biting hard foods are among the factors most associated with shorter crown lifespan. Individual outcomes vary.
What is the difference between a porcelain crown and a zirconia crown?
Both are tooth-coloured and used when appearance matters. Porcelain crowns, including all-ceramic types, are often used on front teeth and can be closely matched to adjacent teeth. Zirconia is a high-strength ceramic that is durable enough for back teeth while still maintaining a natural appearance. The right choice depends on the tooth’s location, the forces it faces, and your individual situation. Your dentist will discuss the options most suited to your needs.
Can a dental crown be placed on any tooth?
Crowns can be placed on most teeth, but there needs to be enough healthy tooth structure remaining to support one. If a tooth is severely broken down, a core build-up using filling material may be done first to create a stable base. In some cases, where a tooth cannot be restored at all, extraction may be the more appropriate option. Your dentist will assess the tooth and discuss what is possible before any treatment is planned.
