How long does the pain normally last after tooth extraction/bone graft?

Short lived : Usually only a day or two , you may experience some discomfort requiring an otc medication for up to a week. Its really not that bad!

Not long at all: Some patients may have discomfort for the first day. Other patients may be a few days. Depends on how smooth the procedure went, if the tooth was infected and the patient (if there are any medical issues).

Vary: It is vary from 1 day to 4 weeks depending on the severity and healing of the graft. No graft should be done on the site of infection unless absolute necessary. It is much better to resolve the infection first prior to grafting.
