Zenda,
My experience with ORN and HBO was all overseen by my head and neck oral surgeon (same as maxillofacial). I did see a regular dr in the HBO treatment area that kept an eye on things. I would recommend seeing a head and neck surgeon as well. My HBO treatments helped me heal overall but I didn't have an infection, I just wasn't healing from radiation and I had the ORN. They had to take all the teeth and bone I had left due to the ORN but I am a "special" case.
