I have not heard of either of those options, just the three I have had. Having had my perfect teeth removed after a year and a half battle between my dentist and hematology oncologist, I have now been without the ability to chew or really eat much of anything for roughly nine months. Finally got my dentures a week ago after two grueling dental surgeries. I am glad I did now, having just met someone who had breast cancer that metastasized all over her body and had a cavity filled and no one advised her of the very real concerns regarding necrotic jaw problems. She is now scheduled to have her entire jaw removed. Can't imagine, honestly. I would highly encourage anyone getting bone shots of any kind to check and double check the risks associated with the bone meds. I had Fosamax twenty four years ago for a long time and another similar prescription med but never heard anything about risks similar to what exists now with perhaps stronger and better meds ? Best wishes to everyone dealing with any bone issues. It isn't a lot of fun at any age or any stage of the game.
