About crown & bridge
A dental crown is a tooth-shaped cap that fits over a damaged tooth to restore its shape, strength and appearance. A dental bridge replaces one or more missing teeth by attaching a replacement tooth to supports on either side of the gap.
Crowns and bridges are some of the most common restorations in dentistry. They are made to fit your mouth, to feel comfortable and to look like the rest of your teeth.
What it involves
- An examination of the tooth or gap, sometimes with X-rays, to confirm that a crown or bridge is suitable.
- Preparing the tooth (or the supporting teeth for a bridge) so that the restoration fits over it.
- Taking an impression or scan so that the restoration can be made to fit precisely.
- Fitting a temporary crown or bridge while the final one is made.
- Fitting and adjusting the final restoration, then checking your bite.
Benefits
- A crown protects a weakened or heavily filled tooth from breaking.
- A bridge can fill a gap so that you can chew and smile more comfortably.
- Restorations can be matched to the colour and shape of your own teeth.
- Can improve the appearance of badly shaped or discoloured teeth.
- A long-lasting solution when cared for properly.
What patients can expect
- Treatment usually takes more than one visit.
- A temporary restoration protects the tooth between visits. Avoid sticky foods that could pull it off.
- Your new crown or bridge can feel slightly different for a few days while you get used to it.
- Cleaning is important: brush well and clean carefully around and under the restoration.
Who it may be suitable for
- People with a cracked, worn or heavily filled tooth.
- People who have had a tooth treated that needs extra strength and protection.
- People with one or more missing teeth who have healthy teeth next to the gap.
- Anyone who wants to improve the shape or look of a damaged tooth.
Why professional care matters
A crown or bridge has to fit precisely. If the fit is slightly off, food and bacteria can get underneath it, or the bite can feel uncomfortable. Professional planning, preparation and fitting make sure the restoration protects your teeth rather than causing new problems.
This page is general information to help you understand the treatment. Results vary between patients, and only a dentist can advise what is right for you after examining your teeth.
Frequently asked questions
What is the difference between a crown and a bridge?
A crown covers and protects a single tooth. A bridge replaces missing teeth and is supported by crowns or attachments on the neighbouring teeth.
How long do crowns and bridges last?
Many last for years. Their lifespan depends on the material, the strength of the supporting teeth, your bite and how well you look after your teeth and gums.
Will the crown look like my other teeth?
Crowns and bridges can be made to match the colour, size and shape of your natural teeth, so that they blend into your smile.
Is the preparation painful?
The tooth and surrounding gum are usually numbed before preparation. You should feel pressure rather than pain. Tell your dentist straight away if you feel any pain.
How do I clean a bridge?
Brush normally and clean underneath the replacement tooth with floss threaders or interdental brushes, as your dentist shows you.
