Please I live in ny and an in severe pain my gums are killing me and I'm pretty sure I need a root canal or have an abscess and no insurance?

Dental no insurance. You definitely need a check up. Having no insurance is a real problem. I would suggest you find a dental school nearby and see if they will treat you.
Stony Brook. Make an appointment to be seen at stony brook dental school. You will pay lower fees than going to a private office.
