When a crown may be recommended
Sometimes a tooth needs more protection than a filling can give. A crown may be suggested for:
- A tooth that is cracked or broken
- A tooth with a large filling and little natural structure left
- A tooth that has had root canal treatment
- A tooth that is badly worn down
- A dental implant, where the crown replaces the visible part of the missing tooth
What a crown is for
A crown holds a weakened tooth together, helps stop it from breaking further and restores its shape so you can bite and chew with it again. It can also improve the appearance of a tooth that is damaged or discoloured.
What to expect
The exact steps depend on the tooth and the type of crown. In general, getting a crown involves:
- Examining the tooth, often with an X-ray, to check it is healthy enough for a crown
- Numbing the area and shaping the tooth so the crown can fit over it
- Taking an impression or scan so the crown can be made to fit your tooth and bite
- Fitting a temporary crown, if needed, while the permanent crown is being made
- Checking the fit, appearance and bite of the final crown before fixing it in place
Because a crown is made to fit your tooth, the process often takes more than one visit.
Things to consider
- Crowns can be made from different materials, including metal, ceramic or a combination of both. Your dentist can explain the options suitable for the position of your tooth.
- Some of the outer tooth is removed so the crown has room to fit.
- A crowned tooth can still decay at the edge where the crown meets the gum, so brushing, cleaning between the teeth and regular check-ups remain important.
- Like natural teeth, crowns can chip or wear over time and may need replacing in the future.
When to see a dentist
Book a visit if a tooth has cracked or broken, a large filling has fallen out, or a tooth hurts when you bite. If you already have a crown that feels loose, has come off or feels uncomfortable, keep it safe and call the clinic.
Questions about dental crowns
How long does a dental crown last?
It depends on the material, the position of the tooth, your bite and how well the tooth and the gum around it are cared for. With good home care and regular check-ups, crowns can last for many years.
Will a crown look like my natural teeth?
Tooth-coloured crowns can be shaded to blend with the teeth next to them. Your dentist can explain which materials are suitable for the tooth being treated.
Is getting a crown painful?
The tooth is numbed with local anaesthetic while it is being prepared. Some sensitivity for a short time afterwards is common.
What should I do if my crown comes off?
Keep the crown safe, avoid chewing on that side and call the clinic. Do not try to fix it back in place with household glue.
