Actually the question is about O2 as a preventer of osteoradionecrosis, or to most people healing complications during dental surgery after radiation treatments.
Here is the OCF page that speaks to that.

Personally, if you have had radiation treatments I would not have ANY extraction without doing this. I do recommend that your surgeon talk to your oncologist PRIOR to doing anything. In many cases impacted wisdom teeth do not need to be removed. I have had two of them for my entire life that are buried in the mandible, horizontally impacted, and have ever been an issue. They can if in direct contact with the roots of the second molars in front of them, be a problem sometimes as they are capable of resorbing some of the calcium from those roots and damaging the second molars. This is very age related. Some people have an issue of them crowding the lower teeth together towards the midline, and dentists want to take them out to prevent that. But this is a much lesser issue.
After radiation any dental surgery should be taken very seriously, as osteoradionecrosis is a serious issue for all of us that have ben radiated. It can start a cascade of problems and infections from a non healing extraction site that can be very difficult to treat.
