Hi Don,
Correct, I had the bottom 3rd molar surgically extracted and stitched along with all my other teeth, including molars, last November, and did the Marx Protocol 20/10 HBOT before and after, but the 3rd molar socket opened up, had exposed bone for four months, which required another surgery in March along with bone shaving, buccal flap to close the socket, and stitched, which helped briefly, but it opened and after 4 months it still didn't fully heal, and had exposed bone, so I had to see another oral maxillofascial surgeon, who basically specializes in ORN, for possible major surgery, but he determined it was healing over, slowly, and will take a while, but I'm still not out of the woods yet, and was eventually released back to my regular oral surgeon for close follow-up, cleaning, which were weekly for quite a while.
After radiation, if you have exposed bone in the mouth longer than 3 months you're talking about possible ORN, which have different grades, and with such the doctors didn't take it lightly, and took quite seriously to the extent of treating like a cancer being the consequences can be so debilitating.
