Simple extractions are ones where the tooth is grabbed by forceps and the tooth is extracted with no problems. A surgical extraction is when drilling and/or bone removal is necessary to remove the tooth and/or root (the tooth breaks and it becomes necessary to dig the roots out of the jaw).

Stitches are rarely required for single tooth extractions.

Sounds like you are having bicuspid extraction treatment for orthodontics. I'm sorry to hear that, especially if you are a female...

Bicuspid extraction along with retraction of anterior teeth have a high probability of causing TMJ after braces are removed. You may want to consider a non-extraction technique where bicuspid teeth are not removed. There are better and more modern ways to treat than the way it was taught over 75 years ago. Get a second opinion, preferably from an orthodontist who knows about functional orthodontics.
