REQUEST: Dental Assistance

I have been having extreme pain in the back right part of my mouth because of badly positioned wisdom teeth now have to get at least one of them removed which I have been told will cost me about $900 per tooth. This pain is costing me the ability to eat well as well as sleep, I have no other forms of support as I was only recently able to end a 2-year-stint of homelessness. Currently, I am a struggling student, any and all help you can offer with this needed surgery would be appreciated.
