A back lower molar started hurting slightly a few weeks ago. Now it hurts alot more, esp if I bite down on it. There is a small amount of pain that never stops now and I just touched the outside gums next to the tooth and it sent a shock of pain all the way into my jaw bone. I do not have dental insurance and cannot afford a major repair such as a root canal, or crown. I know it is not advisable, but wondered if it any dentist nowadays would be willing to just pull the tooth and be done with it?
