Its been 3 days since wisdom tooth removal andmy jaw bone is swollen and painful...could i have a fractured jaw bone?

Probably not: Usually after extraction, because the patient is open for long time, most patient experience tenderness and pain one site effect of extraction is swelling, usually it is the most after 48 hrs and start going down depends on severity of extraction best to consult with your dentist to rule out any fracture, it will show on an xray.

Could not: Speculate - best to contact the treating dentist to be evaluated. Hope this helps.

Max Swelling: In my practice I advise my patients that the swelling following surgery may continue to increase in size for the first two to three days and will usually reach its maximum by the third day. Typically the swelling will start to resolve after the third day. If you are concerned about the possibility of a fractured jaw, the surgeon performing your surgery would be the best person to address this.
