medical malpractice law?

I needed all teeth extraction and full dentures. I got half my teeth extracted from another dentist then the other that were left (10 in the front) were extracted by my main dentist. However, he extracted ALL 10 at once. Is this allowed? My body temperature increased and I got a headache. He put the immediate dentures in right away.

Not only that but he never told me that my insurance can only pay for the top dentures so he told them that he only extracted my top teeth and that he only made an upper denture. I found out that when the next annual cycle comes in (when I get another 1000 to use for dental work) he will use all of that up by telling them he did the lower denture and lower tooth extraction. If I tell my insurance what he is doing he is just going to send me the bill because everyone signs a form before all of these procedures are done.

Not only THIS but the dentures are horrible and do not fit and he does NOT want to make any adjustments because the insurance does not pay well. I look ape-like with the dentures in my mouth and can only wear the upper denture. I haven't eaten properly in 12 months and have lost a total of 35 lbs.

I can't go to a new dentist because he took all the money from the insurance plus whatever is coming is within the next annual cycle. If I get my own dentures I would have to pay out of my pocket.

What are my options?
