What Is a Dental Crown?
A crown is a tooth-shaped cap that covers a damaged tooth completely, restoring its shape and strength. It is the usual final step after root canal treatment on back teeth, because root-canal-treated teeth become more brittle and can crack without protection.
Crown Materials
Metal-ceramic (PFM)
A metal base with tooth-coloured porcelain on top. Strong and economical; a good choice for back teeth.
Zirconia
Metal-free, very strong and natural-looking. Preferred for front teeth and for patients who want the most natural result.
When a Crown or Bridge Helps
- After root canal treatment
- Large fillings or cracked teeth
- Broken or badly worn teeth
- Discoloured or misshapen teeth (as part of smile designing)
- On top of a dental implant
- A bridge to replace one or two missing teeth
Getting a Crown
Examination & plan
We check the tooth and its X-ray, and explain the material options and full cost.
Tooth preparation
The tooth is numbed and gently shaped; a scan or impression is taken and a temporary crown placed.
Fitting
About a week later the final crown is checked for fit, bite and shade, then cemented.
Care
Brush and floss normally, and keep your 6-monthly check-ups.
Cost depends on the material and number of teeth. See the dental crown cost guide, or call 7874 483 483.
Frequently Asked Questions
A crown is usually advised after root canal treatment on a back tooth, for a tooth with a large filling or a crack, to restore a badly worn or broken tooth, or on top of a dental implant.
Both are strong and reliable. Zirconia is metal-free and looks more natural, especially for front teeth; metal-ceramic crowns cost less and suit back teeth well. We show you both and explain the difference for your tooth.
Usually two visits: one to prepare the tooth and take a scan or impression (with a temporary crown), and a second to fit the final crown about a week later.
With good brushing, flossing and regular check-ups, crowns commonly last many years. Avoid biting very hard objects and see us if the crown feels loose.
A bridge replaces a missing tooth by attaching a false tooth to crowns on the teeth either side. It is fixed (not removable). An implant is the alternative that doesn't involve the neighbouring teeth — we compare both with you.
