oral surgery caution

One year and a half ago, Robbie had his wisdom teeth out. At the pre-op appointment I felt ill at ease. The dr. did not instill confidence, although he'd been inpractice for many yrs and had been recommended to us by our dentist. Immediately following the surgery, Robbie felt there was something "not right". He began having swelling slightly forward of the excavated area for the following nine months. Being away at college made it tough to follow up. In May, he saw the dr. again because of another flare up and was given antibiotics and told to keep an eye on it. Over the summer, he had another more severe flare up (swelling, pain) and saw a dentist on Catalina Island. He referred R to an endodontist in Torrance, who did an emergency root canal on the adjacent molar. The infection was extreme. He came home for three days in August and saw another oral surgeon who was confounded even after extra radiographics (more $$$) and scheduled an exploratory surgery for November, when R would be home for Thanksgiving. A gold crown was put on the root canal tooth by a dentist in So Cal. It is Dec. 16th, and I have now the biopsy results from the Nov. 26th surgery. A foreign body (15X8X3mm) was found .. a result of the wisdom tooth extraction, August 2007. It is finished.
