Actually, I don't see how someone can make a generalization that just the mandibular teeth need to go. The ones that absolutely need to go are any that are in a compromised condition, or there are low expectations of your ability to keep them free of periodontal disease, caries, etc. afterwards. Extractions after treatment have their own set of new unique issues. So arbitrarily taking out all the uppers or lowers makes little sense. It is taking out the ones that are already compromised from a periodontal standpoint, restorative standpoint (beyond salvage), or those which they feel may cause future problems - creating the necessity for extraction in the period after radiation.

I have just read your first three posts since coming here, and clearly you are frustrated, angry and more. While some of this is common to new patients, clearly the manner in which you deal with all this can make the experience, and interactions with your treatment team even worse. Many of us here have gone through counseling while in the process, taken antidepressants, and more. I hope that you are also getting a professional opinion, and trained person to listen to your emotional issues regarding all this. When someone comes here with the level of emotion that you express (I HATE my doctor, I hate everyone, and everything, etc.) it appears that you are not getting the emotional support that you need. Venting here is common, but venting is not a solution to the emotional issues. I was angry with my doctors as well, particularly those that missed my disease and allowed this to get into a late stage, but I also had the benefit of professional psychiatric counsel and eventually meds that kept that in balance. This is not an easy path, and dealing with issues besides the actual medical treatments (which in themselves can be overwhelming) is part of the process. Please seek out that ancillary professional support so that the emotional part of this is something that you can deal with.
