Sierra Smiles Dentistry

I went to Sierra Smiles Dental office in the Rock Creek Plaza, 2503 Bell Road Auburn, Ca 95603 because my back tooth had chipped from eating sunflower seeds. It wasnt a big chip but it was near my tongue and didn't want to risk cutting my tongue. I had seen Dr. James Mungcal and he proceeded to file not just one of my teeth but two teeth. My other tooth was perfect and was unsure why he filed my other tooth. Dr. Mungcal filed my two teeth so far that instantly i was in unbearable pain despite the fact that i was full of novacaine. I was told that my teeth were just sensitive and it would clear up in a day or two. Well, when the novacaine wore off, i was in tears as my teeth were throbbing so bad. I had trouble eating, sleeping, etc. There's not many things worse than tooth pain. Dr. Mungcal told me i would need to put crowns on my teeth because my teeth were so small and the nerves were completely exposed. So, after the crowns, the tooth pain stayed unbearable and could not stand it. So, now because of a small chip in my tooth, ive endured 2Crowns, and then 2 Root Canals. I was understanably upset, i threatened to sue them if i have to endure anymore as this is unacceptable. I was told they would take off one of the root canals and thats all they would do. They never covered my root canals and because i have deep pits in my teeth, food is stuck constantly. Help me.
