A dental crown is more than a cosmetic cover placed over a tooth. It is a restorative treatment used to protect or rebuild a tooth that has been weakened, broken, heavily restored, or otherwise needs more support than a conventional filling can provide. A dental clinic in Edmonton can assess the tooth and determine whether a crown is an appropriate treatment option.
Crowns can also be used with dental bridges, dental implants, and root-canal-treated teeth, depending on the clinical situation.
What is a dental crown?
A crown is a custom-made restoration that covers the visible portion of a tooth.
Think of it as a fitted shell that restores the tooth’s shape and function after the dentist has prepared the underlying tooth.
Crowns are commonly considered when a tooth:
- Has lost substantial structure through decay
- Is cracked or significantly broken
- Has a large filling and not enough remaining tooth structure
- Has been heavily worn
- Has been treated with a root canal
- Needs to support a bridge
- Is part of an implant restoration
The purpose is not always the same. In one case, the primary concern may be strength; in another, it may be restoring the shape, appearance, or function of the tooth.

Why might a filling not be enough?
A filling restores lost tooth structure, but it does not cover the entire tooth.
When too much structure has been lost, a crown may provide more full-coverage protection.
This is one reason the treatment decision depends on the remaining tooth structure rather than simply the size of the cavity on an X-ray.
A dentist may consider:
- How much healthy tooth remains
- Whether the tooth is cracked
- How much biting force it receives
- Whether the tooth has already been heavily restored
- Whether the tooth has undergone root canal treatment
- What functional and aesthetic demands apply
What are dental crowns made of?
Several materials are available.
Metal crowns
Metal crowns are known for strength and wear resistance. They are often considered where appearance is less important.
Their main drawback is obvious: the metallic appearance is not the same as the colour of a natural tooth.
Porcelain or ceramic crowns
These materials can offer a more tooth-like appearance and are often considered when aesthetics are important.
The exact ceramic system matters, and not every material is equally suited to every tooth.
Porcelain-fused-to-metal crowns
These combine a metal base with a tooth-coloured outer layer.
They have been used for many years because they can provide a balance between structural support and appearance.
Resin-based restorations
Resin materials can be used in certain circumstances, although their durability and indications differ from those of other crown materials.
The right material depends on the tooth, bite, location, aesthetic goals, and other clinical factors rather than a universal “best” material.
How long does a dental crown last?
Crown longevity varies.
Cleveland Clinic reports that crowns commonly last around five to 15 years with proper care, although individual restorations can last longer or require replacement sooner depending on factors such as wear, damage, oral hygiene, and the condition of the underlying tooth.
The important point is that a crown is not necessarily permanent.
A crown may eventually need repair or replacement because of:
- Fracture or wear
- Decay around the restoration
- Changes in the supporting tooth
- Gum recession or changes in surrounding tissues
- Problems with the fit
- Damage from clenching or grinding
What happens during a crown procedure?
The exact workflow varies, but a crown typically involves several stages.
Assessment: The tooth is evaluated to determine whether a crown is appropriate.
Preparation: The tooth is shaped to create space for the restoration.
Impression or digital scan: The prepared tooth is recorded so the crown can be fabricated.
Temporary protection: A temporary restoration may be placed while the final crown is being made.
Try-in: The final crown is checked for fit, shape, colour and bite.
Cementation: Once everything is satisfactory, the crown is secured.
The Alberta Dental Association’s 2026 abbreviated fee guide also distinguishes the professional crown fee from laboratory charges, showing why two crown quotes can have different structures.
What affects the cost of a crown?
There is no single “dental crown price.”
Cost can depend on:
- Crown material
- Laboratory charges
- Tooth location
- Complexity of the preparation
- Whether the tooth needs a buildup
- Whether root canal treatment is necessary
- Temporary restoration requirements
- The provider’s fee structure
For example, the 2026 Alberta fee guide lists a suggested professional fee of $1,072.55 for an uncomplicated porcelain/ceramic/polymer-glass crown fused to a metal base, while explicitly noting that laboratory charges may be additional.
That is why an online number should be treated as a benchmark rather than a guaranteed final price.
What should you ask before getting a crown?
A useful consultation should answer practical questions, including:
- Why is a crown being recommended instead of a filling?
- How much natural tooth structure remains?
- Which materials are suitable?
- Does the tooth need a root canal first?
- Is a buildup or post required?
- Does the estimate include the temporary crown?
- Are laboratory charges included?
- How will the bite be checked?
- What should you avoid while the temporary crown is in place?
- What factors could require the crown to be replaced later?
These questions can make a treatment plan much easier to understand.
Are dental crowns only for damaged teeth?
No.
Crowns can have both restorative and reconstructive roles. They can cover a weakened natural tooth, attach to a bridge, or form the visible part of an implant restoration.
That is why the term “crown” alone does not tell you why someone needs one.
The practical takeaway
A dental crown is a custom restoration designed to protect, rebuild, or replace the visible structure of a damaged or weakened tooth. The material, location, underlying tooth condition, and laboratory work all matter. Rather than choosing a crown by material name alone, it is more useful to start with the condition of the tooth and the purpose of the restoration. If you are considering a dental crown, book a visit with your dentist to discuss the most suitable option for your tooth.
FAQs
What exactly is a dental crown?
A crown is a custom restoration that covers the visible portion of a tooth to restore its strength, shape, and function.
When does a tooth need a crown?
Crowns may be recommended for significantly damaged, broken, worn or heavily restored teeth, including some teeth after root canal treatment.
What is the longest-lasting type of dental crown?
Longevity varies by material and individual circumstances. Metal crowns are known for strong wear resistance, but the appropriate material depends on the specific tooth and clinical situation.
How long do crowns usually last?
A commonly cited range is about five to 15 years with proper care, although some can last longer.
Is a crown stronger than a filling?
A crown provides full coverage and may be appropriate when a tooth has lost more structure than a conventional filling can reliably restore. The appropriate option depends on the condition of the tooth.
Are dental crowns expensive?
The price varies with material, laboratory charges, tooth condition, and other treatment requirements. Provincial fee guides are useful benchmarks, but individual provider fees vary.
Can a crown be used after a root canal?
Yes. A crown may be used to restore and protect a root-canal-treated tooth, depending on the tooth and remaining structure.
