Crown or bridge? How to choose

Crowns and bridges are often mentioned together, and patients aren’t always sure which one they’ve been offered or why. They solve different problems. Here’s the difference, and the questions worth asking.

The short answer

So the first question isn’t really crown or bridge, but whether the tooth can be saved.

A crown

Covers and protects a tooth you still have.

A bridge

Replaces a tooth that’s missing, using the teeth either side for support.

When a crown makes sense

A crown is a cap that fits over the whole tooth. It’s usually recommended when a tooth is still healthy at the root but has been weakened.

When a bridge makes sense

A bridge is an option once a tooth has been lost or can’t be saved.

The option in between: saving the tooth

Sometimes a tooth that looks like it needs removing can be kept with root canal treatment followed by a crown. Keeping your own tooth is usually the first thing we look at, as long as it has a reasonable outlook. If it’s cracked below the gum or has very little support left, replacing it may be the more sensible long-term choice.

If the tooth has to go

Bridge

Fixed. No surgery. Neighbouring teeth are shaped for crowns. Usually finished in a few weeks.

Fixed. Neighbouring teeth untouched. Needs surgery and several months to finish.

Partial denture

Removable. No surgery. Clasps rest on nearby teeth. Usually finished in a few weeks.

Questions to ask at your consultation

Write these down and bring them along. A good plan should answer all of them.

What affects the cost

A crown covers one tooth. A bridge usually involves at least three units: two supporting crowns and the false tooth. Materials, any treatment needed first and the number of teeth all affect the cost.
