Do I have a malpractice lawsuit against a dental company?

I went to a dental company on June 04 2011. While I was there for a routine dental check up, the dentist discovered a bad tooth. He said "that the tooth needed to be removed. At that time we went over different opinions I had to replace the tooth. I choose to have the dentist remove the tooth and place a bridge there. During the tooth extracting I was given several shots of numbing medicine which wasn't not working. I was letting the dentist know every time and she would still continue with the procedure disregarding my pain. When it came time to remove the tooth I was extreme pain and she continue to pull my tooth. When my tooth came I asked to see it cause something didn't feel right. I was told no they don't show the tooth.She then placed a temporary bridge in my mouth. He wrote me a prescription for a pain medication. When I got home I discovered that she had tore out the top part of my of my gum as well. When I called to report the extreme pain I was in, all that was said was that she would write another prescription for a pain medication. I ended up going into the dentist to let them see I was told it was healing just find. She had a head dentist look and he asked if I was taking the antibiotics that were given. I responded that I never got any. She then wrote a prescription for another medication, but by that time it was too late. I had an infection already. I ended going to the emergency room because there was too much pain and I wasn't getting any help at the dentist. When the doctor saw it, she was confused why the dentist left all my nerves exposed. She let me know I had a really bad infection. There is some more to the story. I am running out of typing space here. I have a picture and more to tell if someone would please contact me.
