When a filling is not enough
Why a tooth might need a crown
Fillings work well for small holes. When a tooth has lost a large part of its structure, a filling can leave thin walls that crack under chewing, and that is where a crown helps. It wraps the whole tooth, holding it together and spreading the biting load.
Our dentists usually recommend a crown for one of these reasons:
- A large old filling that has started to break down or leaves little natural tooth behind
- A cracked or chipped tooth that is sore when you bite or at risk of splitting
- A back tooth after root canal treatment, which can become brittle over time
- A worn or misshapen tooth, from grinding, acid wear or a tooth that never grew to full size
- A dark or stained tooth that whitening cannot lighten
- A dental implant, where the crown is the visible tooth on the implant post
Not sure whether your tooth needs a crown or a filling? Our article on crown versus filling sets out how dentists decide. If a tooth is missing altogether, see crowns and bridges or single tooth implants.
