GET A SECOND OPINION! I was told I needed a root canal. I got a second opinion and I didn't need that work I think he just wanted the extra $800 or whatever for that work. Is all I needed was a filling and a crown put on....which I had done AT A DIFFERENT DENTIST! Also, watch out for their billing. I was told - a YEAR LATER - that I owed them money my insurance hadn't paid. When asked to see copies, they said they didn't need to give me them and would file against my credit for non-payment... STAY AWAY FROM DR. NELSON!!!
