I had a filling done in my childhood that was silver. I went to the dentist about 6 months ago, and they fixed some cavities and replaced the silver filling with the white stuff. I was experiencing pain weeks after in the replaced filling. I went in and they fixed the bite. I had to go in an additional time for them to fix the bite because it was still hurting. This last time I went in, a couple weeka ago, they redid the filling. I am still having the same pain when chewing. I'm worried because everything I'm reading is pointing to a root canal. I had no pain before any of this started! Interestingly, the dentist who originally redid the filling no longer works there. Is this a doctor error? What are my options? Should I go to a different dentist? Do I need to get lawyers involved? Thank you.
