Hi Patzee, welcome to the community. Forteo does not cause jaw bone problems with tooth extractions. Bisphosphonates (Fosamax, Reclast, Boniva, and Actonel) can "possibly" cause this to happen but the incidence of this is low, unless you've had cancer and then the risk is slightly higher.
Forteo is a man made form of parathyroid hormone, so it's in a completely different class of drugs than bisphosphonates. If you've taken a bisphosphonate at some point, you need to mention this to the oral surgeon, but if not Forteo by itself is not a drug that causes this problem. Actually some Drs are using Forteo after dental implants and extractions to help speed the healing process, "if" the patient took a bisphosphonate for many years (5 or more).
Good luck with your extraction, and double check this information with your surgeon.
Hi Patzee, I forgot to mention a really good article on Forteo that is relatively easy to read and understand. It will tell you just about anything you migh want to know about this man made parathyroid hormone for severe osteoporosis. Here's the link from the Cleveland Clinic. The article may appear to be several years old, but I know they have updated it many times, and the general info will not change, so don't be put off by the date I last saw.
Good luck, but you are almost done with it so now you'll have to decide what to take next to retain the gains from it, if you did indeed improve greatly on it like many have. Of course, there will always be some who didn't do as well as I did or like many of our other members since we all react differently. If you want to let us know how your surgery goes, please do, and I hope it's smooth sailing through that procedure.
