Does your tooth need a crown?
A crown is a cap that covers a weak tooth, restores its shape and protects it from breaking. We recommend one only when a filling will not do.
A crown is usually advised after a root canal, for a large filling, or for a cracked or worn tooth. It is made to match your bite and the colour of your teeth.

When a crown is usually the right answer
- After a root canal on a back tooth
- A large old filling around which the tooth is weak
- A cracked tooth that needs to be held together
- A badly worn tooth
- Covering a dental implant
What happens, step by step
Look
We check the tooth, the bite and the gum around it.
Explain
We discuss materials, appearance and cost before preparing the tooth.
Prepare
Under local anaesthetic, we shape the tooth, take a scan or impression and fit a temporary crown.
Fit
At the second visit, the crown is checked for fit, bite and colour, then cemented.
Materials
Tooth-coloured ceramics are common for front teeth and increasingly used for back teeth. Other materials may be better where strength matters most. We choose based on the tooth, your bite and what you want it to look like, and we explain the trade-offs.
Good care of the crown, including cleaning around the gum line, matters as much as the crown itself.
Questions patients ask
How long does a crown last?
It depends on the tooth, the material, your bite and how well you clean it. We discuss realistic expectations when planning.
Will it look natural?
Yes. We match shade and shape to your neighbouring teeth.
Is the preparation uncomfortable?
It is done under local anaesthetic. Some sensitivity afterwards is common and settles.
Do I need a crown after a root canal?
Usually for back teeth, to prevent fracture. Front teeth sometimes only need a filling.
How many visits?
Typically two. We tell you the schedule before we begin.
