Dave,

Hyperbaric Oxygen Treatments are in fact covered by medical carriers as opposed to dental. Some carriers still consider the treatment to be "experimental" and balk at covering. You quite possibly would need a "letter of necessity" from your doc which should be no problem. It is my information that there is an approximate 25% chance of ORN occurrence to the mandible if you have undergone radiation treatment. The ORN can come about if the mandible suffers any form of trauma to include a tooth extraction. I fell into that percentage but also fell into the "less than 5%" chance of ORN even with a total of 30 HBO treatments.
