I had osteoporosis prior to my 2005 SCC dx and was on Fosamax for five years from 2002 until 2007. My condition improved to a dx of osteopenia. I discontinued Fosamax after some research into the side effects. At that time I was getting plenty of weight-bearing exercise and calcium through my diet. However, in 2011 I developed osteoradionecrosis in my right mandible. I increased my calcium and vitamin D3 through supplements. Several doctors have told me that Fosamax may have been a factor in developing osteoradionecrosis. The XRT in 2005 was the primary factor in ORN. I do have a family history of osteoporosis. I too have had a number of fillings in the past seven years and use fluoride nightly.

All the best to you in managing after effects of radiation.
