Emergency dental surgery

So for months I've been trying to get a dentist appointment to try and take care of two badly broken teeth (They didn't grow in all the way and the roots are wrapped around major nerves) I've been sent back and forth to dentists with referals to surgically remove them. Today I found out that 2 of my wisdom teeth are also resting comfortably on top of the nerves and that the only way to remove them would be to go in surgically because other wise removal would cause permanent numbness and paralysis in my face. Not only that, I also found out that to be able to remove the (now 4 teeth) I would have to have two bone grafts done in order to be able to do so and for my jaw and mouth to heal correctly.

OF COURSE my insurance doesn't cover ANY of this..how convenient. I was given an estimate of 850.00 for the bone grafts alone, and each extraction could be between 200.00-450.00

I would put it off until I had the money myself, but the doctors think that this might be a major contributing factor to why I've been so ill and weak, not only that it causes me constant migraines and immobilizing dizziness. I've done all the research I can do, and have made all the calls I can make through dentical and MediCal..and I am down to this as a last resort option..I really don't know what to do anymore at this point and I am beyond terrified but this has to be taken care of or my health will continue to get worse.
