Not 100%, and not happy

There is still a sliver of lost sensation in my tongue, on the right side. I'm thinking of paying another visit to the dentist who caused the paresthesia -- although I'm not sure what good it will do, ultimately, since he can't repair the damage - just monitor it. I no longer feel the pins-and-needles sensation of the nerves refiring on a daily basis; now it happens but on occasion -once every 10 days. Having a dead spot on your tongue is more than just annoying: It impacts your quality of life. It impacts my ability to trust a dentist with Novacaine, which I know I'll eventually have to use again. That's how teeth are; they break down. Here's the other thing: While I am no longer actively his patient, I still have a bill to pay - over $1,100 that is still owed to the credit card agency. Yes, I knew the risk when I had the procedure done in June 2012, but it was a simple sedation to replace 2 fillings and install a crown. Nothing complicated. Beyond follow-up appointments, which were not build, procedures, no offer of a refund. I am contemplating asking for a refund.
