Sorry to hear how bad you're feeling JJ. This won't help you right at the minute,but,the Royal has a Dental Teaching Clinic which takes in patients on a first come first serve basis. These are senior students observed at all times by experienced dentists. My friend had her crowns successfully done there and my husband had a nightmare agony relieved when he couldn't get an ordinary dentist's appointment. Checked their "page" there,but they only are open during term time. It's something to think about though?
