Has anyone ever switched dentists in the middle of having major dental work done due to negligence?

I was at the dentist's office having work done on fitting a new crown. While shaving the tooth down with the drill, somehow, someway, the drill got away from the dentist and bore into the underside of my tongue requiring about 5mins and about 10 swatches of cotton to control the bleeding before he could continue. I fully understand mistakes happen but the problem is that although I knew, felt, and heard it happen, the dentist said nothing. When the prep for the crowwn was done, he fitted the plastic temps, shook my hand, and walked out saying see you in two weeks. Having faith and trust in my dentist, I thought the problem was small and taken care but when I got home, I noticed a hole the size of a penny in my tongue and a gigantic vein/artery sticking out from the hole. Immediately went to the ER and was examined by two doctors,both of whom said the wound would require stitches and antibiotics; four stitches later and a ten day course of some powerful antibiotics and I was free to go. My first and foremost pressing problem is that I obviously don't want to go back to this dentist to have him complete the work he started, not because of the mistake, but because he never said anything and let me walk out of his office with a potentially serious condition brewing in my mouth. How do I get another dentist to complete the work without having to repay for the entire crown again? My next question is does anybody think this dentist was negligent in leaving my mouth in this condition without advising me that it might need attention that is beyond his capabilities, some antibiotics, or at the very least, to monitor the condition carefully? If so, should he take some money off the bill, and if so, how much would be reasonable?

Wow you are asking about many issues. I do think that the dentist should have at the very least mentioned the cut to you and at least given you some ointment for it and yes possibly paced you on antibiotics as a preventive measure. As to whether you needed stitches is a judgment call especially if it was not bleeding. Perhaps because it was not and the floor of the mouth having such a good blood supply and heals very quickly,he thought the stitches were not needed. As to seeing another dentist at this stage, would be somewhat tricky. I would meet with the dentist and explain the events that took place after the dental appointment. At the very least, he should be responsible for any medical bills you incurred. As to what other financial considerations he should or would make it in his hands. I wish you good luck and am sorry for your unfortunate situation.
