Hello Rchurch

Put your mind at rest after 12 years the blood vessels that were destroyed during radiotherapy and put you at risk of osteoradionecrosis of the jaw will have recovered sufficiently enough that tooth extraction should not be a problem. I had radiotherapy to the jaw 11 years ago and very recently had a tooth extracted. I am currently on immunotherapy and Denosumab which carries its own risk of osteonecrosis of the jaw. As a precaution the denosumab was stopped for a few months and I was referred by my dentist to the hospital for the extraction. I was given a course of antibiotics and mouthwash to use and a check up one month later. The extraction site is healthy and Ive had no problems since. Id trust your highly qualified dentists opinion over stuff on the internet.
