Dr. McCarthy installed an implant that failed and came out within a few months. He charged me in full for a replacement. I was treated by Dr. McCarthy and Dr. Wang who works in his office. Their atitude is that pain is a part of the dental process. Their treatment was the most painful experience I have ever had. I paid in cash but could not get change. when I asked them to send me a check, they created new fees so I never got my change. They estimated the cost of my treatment to be $1500. When I arrived at their office, the bill was $2700. Don't use this practice.
