I've already mentioned this on FB, but there may be others on here that are not on FB. I'm experiencing bone trying to poke through my gum and although I've not been officially diagnosed, it's looking likely that I have osteonecrosis of the jaw, which can be caused by the taking of Alendronic acid. I only took it for 18 months, and stopped in April 2014, so didn't expect to have a problem now. My dentist has told me to use Corsadyl mouthwash and to see him again in 3 weeks, to keep an eye on it. Does anyone on here have any experience of this? If so, I would like to hear from you.
