For your dentist not to take an x-ray, and then speak rudely to you, is not acceptable. This was not your fault. I would indeed go to the ER, with the exact list you posted, and let them take the x rays. Pain is a symptom that something is indeed wrong. Most hospitals do have a dentist, or OS on hand. There are plenty of patients who come in with some trauma to the mouth and teeth. Take action if you can. 500 miles is a long way to go, and costly to boot. I always take a different route when one fails. I don't repete what clearly didn't work before. That goes for tests, doctors, dentists, the lot of it. My stubborn streak is very evident, and I do eventually find out what is wrong. If that takes some serious squacking, well by golly I squack! I do wish you all the best John. Call the american Dental association also, ask for a referral to an OS closer to you. That is another option. Take care...ginnie
