Tooth extractions
We always try to save a tooth first. When a tooth is too damaged or infected to repair, removing it protects your other teeth and your health.

When a tooth has to come out
Severe decay, a deep crack, advanced gum disease or crowding can all mean a tooth is better removed. We will show you why and talk through the alternatives first.
After the extraction
You go home with clear instructions for the first days. We also talk about replacing the tooth — a bridge, a denture or an implant — so the gap does not cause problems later.

How it works
How an extraction works
Careful, numb and unhurried.
1We examine the tooth
An exam and an X-ray show whether the tooth can be saved and how it sits in the bone.
2The area is numbed
Nothing starts until the tooth and the gum around it are fully numb.
3Aftercare you can follow
You leave with written instructions and a number to call if anything worries you.
