Extraction is the painless removal of complete tooth or the tooth root with minimum damage to the adjoining structures.
Extraction is a painless procedure. This is done by injecting a local anaesthetic solution around the tooth being extracted. This leads to numbness over the injected region leading to any absence of pain sensation. The numbness may stay for an hour to 2 hours after which it gradually recedes. During this time the extraction is carried out.
For a simple extraction stitches are not necessary, unless a difficult extraction needs the gums around the teeth to be incised and reflected to get access to the teeth below.
Simple extraction not requiring stitches.
Surgical removal requiring stitches
Removal of teeth in no case affects the vision of the person and is not related to whether an upper or lower tooth is being extracted.
