Thank you Brian for the information. I am interested in the Pentoxifillyne. Is this taken only before and after extraction or is it something you would take long term. Also I assume it’s a prescription only drug? I’m in the final week of hyperbaric sessions. I’ve gone to an endodontist about a root canal but he said the tooth is not salvageable. The tooth is causing quite a bit of pain and inflammation otherwise I would just put off getting it removed. Also it’s a molar on the bottom so I know I have more risk.
