I really don't know what to do. I went to a local privately owned dentist. I told this man I am on disablity, and he proceeded to call me a "rich man" and do work in my mouth I did not authorize. One of teeth had a stain on it, and he used the drill handle and some kind of round extension in it to basically saw the stain off my tooth. Now, my tooth is very course, and is starting to hurt. Since he did not ASK ME to do the work, it really has me thinking. Is this even a real stain removal process, or do I have to take action?
