Dental Crowns: What They Are and When You Need One

A dental crown is one of the most common restorations in general dentistry, yet many people only hear the word when a dentist recommends one. This guide explains what to expect.
What is a dental crown?
A crown is a custom-made cap that fits over the whole visible part of a tooth. It restores the tooth’s shape, strength and appearance, and is made from ceramic or porcelain shaded to match your other teeth.
Why would I need a crown?
We may recommend a crown if:
- A tooth is heavily filled and the filling is failing
- A tooth is cracked or worn
- A tooth has had root canal treatment and needs protecting
- A tooth is badly misshapen or discoloured and cannot be fixed with a filling
A crown is also the visible part of a dental implant.
What happens when you get a crown?
- Examination. We check the tooth and take an X-ray.
- Preparation. Under local anaesthetic the tooth is shaped so the crown can fit over it, and an impression or scan is taken.
- Temporary crown. This protects the tooth while your permanent crown is made.
- Fitting. We check fit, colour and bite, then cement the crown in place.
Crown, filling or veneer?
A filling is enough when plenty of healthy tooth remains. A crown covers and protects a weakened tooth. A veneer covers only the front of a healthy tooth for cosmetic reasons; see our veneers page.
How do I care for a crown?
Look after it as you would a natural tooth: brush twice a day, clean between your teeth and attend your hygiene visits. The tooth underneath can still decay, so good cleaning at the gum line matters.
How much does a crown cost?
It depends on the tooth and the material, so we give you the cost in writing after an examination rather than quoting a fixed price. There is no obligation to proceed.
