I have a similar situation. Due for my third injection next week and developed gum swelling and pain two weeks ago. Need an extraction. I also had to have an extraction while on forteo two years ago. I was told there was no connection to the meds. It must either be the meds or the osteo because I have never had these type of tooth problems before! Please keep me posted on your experience and I will do the same. I am also waiting to hear from my dr.
