Heath Problems, short on cash..help please?

It's hard to say what exactly it is. Everything is so close together. Some people don't need their wisdom teeth out because their mouths are big enough. You may have an abscess in that tooth. It would be at the root of the tooth. I would try going to a general dentist. Not oral surgery. All dentist are specialists from the neck up. It could be an infection that could go from the tooth to the ear. Look up the antibiotic and see if it treats both. Not all do. I wish I had an answer being in pain when no one knows what's wrong would be very frustrating! Even more without health insurance. I would ask more about the roots of the teeth maybe that might help? Maybe go to a different dr and get a second opinion if finically you can. Both ear and tooth infections are painful! I hope they can help soon.
