I hope that someone can help me get more info on the treatment of jaw necrosis. I had been taking zometa as part of my cancer treatment for about 8 years when I first started having problems. I noticed what I thought was a piece of tooth coming through the gum on my inside lower jaw, under my back molar. It didn't bother me, so I ignored it until my dentist questioned it. After finding out that it was necrosis of the jaw, and that it was actually a piece of dead bone working its way through the gum, my doc took me off the zometa. A couple of months ago, the piece of bone came out, like a losing a tooth. It left a depression or hole where the bone was, and part of the roots of the molar are visible. That doesn't bother me so much. Its the swollen, spongy and tender gum all around the area that is so painful. I have tried different topical treatments for pain, and also antibiotic mouthwash. The pain recedes but keeps coming back, and the swelling never goes away. Right now, it is so painful that I can hardly eat. My dentist referred me to a gum specialist. I am hoping that someone else will have already dealt with the red tape of medical profession, and can tell me how to get this covered under my medical insurance. None of the periodonist that I have contacted so far, deal with medical insurance. I don't have very good dental insurance, and I beleive that an issue of the jaw bone caused by the treatment of cancer, should be covered as a medical claim, not a dental claim. I am on disability and don't have the money to pay huge dental bills that I am sure will mount up for gum grafts or whatever else they might say. I just read on the discussion board about oxygen treatments and am interested in hearing more about that also. Any help would be greatly appreciated!
