In some cases it may be necessary to extract a tooth 

This may be due to damage to the tooth beyond repair, damage to the tooth’s supporting tissue, the tooth is not growing correctly and causing problems or extraction is needed for orthodontic treatment. 

The area will be numbed using local anaesthetic and the dentist will use various techniques to remove the tooth. This usually involves using forces applied directly to the tooth but in some cases may involve cutting the tooth to remove the roots separately or removing some of the supporting bone to allow the roots to be removed. 

Sutures are usually not needed but in some cases the dentist may recommend having the area sutured. 

Most extractions can be done in the practice however in some situations you may need to be referred to an oral surgeon to manage the extraction. If this is the case your dentist will explain why, where you can be referred and what to expect next. 

After an extraction it is very important to follow the advice of the dentist to avoid complications. You will be given instructions both written and verbal. Below is a link to NHS England website with detailed instructions
