i had full upper dental implants 2 years ago, i had 6 dental posts and bone grafts due to severe bone loss.i had lost my taste for 6 months after surgery.now my taste is back but have severe burning mouth syndrome.went to a gastroenterologist thinking it might be from reflux, he did a endoscopy,it was not that, i saw my gynecologist ,he gave me a higher dose of my estrogen patch which helped hot flashes, but still have burning mouth ,saw the dentist who did implants he gave me a bottle of patented zinc mouthwash with oxygene, it does not help, i have read many articles online abouth burning mouth, i know they dont know what causes it.i dont know who i should see next. do you think it could be nerve damage from the implants? it is so hard to live a normal life with this condition .it is all you can think about.
