I understand that the radiated tissue never improves and that implants are probably not recommended for most of us...The great news is that I have excellent health and quality of life now at 60 and 10 years after treatment... Have about 1/3 to 1/2 saliva (thank God and treatment) and can eat just about anything including jalepeno..unfortunately my teeth had peridontial issues for years and I have had some teeth removed after 3 yrs with Hyperbaric Therapy (dives)...I may currently have a failure of a 15 year implant and will probably have it removed...Is it possible my tissue could be ok now after all this time?? Anyone have any experience?
