Had a total of eight upper dental implants fail all within a year. (extraction of real teeth, bone grafting and sinus lift a year prior implant placement)) All implants have been removed one by one(no bone grafting at time of removals) After removal of implants my denture was still causing pain... My dentist told me to go back to the oral surgeon for alveoloplasty surgery to smooth the gums for denture because of bone protrusion, so I did. I have had severe pain for the past three months since alveoloplasty(Dec. 1st). Cant wear denture and i am in severe chronic pain. what is wrong and what can i do?
