I think I may have an abscess but I'm not sure. I have poor teeth (Do not have the funds to remove them and get dentures) and it started with a toothache on a broken tooth on the bottom row towards the back. The pain was excruciating and to date the only thing that has helped relieve the pain is liquid anesthetics (Advil worked in the beginning but no longer helps) It was throbbing and would send sharp pains to my ear and temple. Starting yesterday the tooth itself became sensitive to the touch. There is no swelling inside my mouth and my gums do not hurt. But after I woke up this morning I notice a slight swell under my chin along the jaw bone (very slight but extremely sensitive to the touch. On the inside the pain is under my tongue. Now that the pain is there my tooth hasn't hurt. I can open and close my mouth fully with only little discomfort but if I touch the area it is very tender. I have insurance but I have no money to pay for the deductible and extraction. Is this an abscess and if so what should I do?
