My regular dentist referred me to Dr. Ribera for my first (and only) root canal. Dr. Ribera is very professional and skilled at his job. It took two visits to complete the procedure, but it was incredibly well done - so well done, in fact, that my current dentist complimented the work when she viewed the x-rays. At the time, the root canal was very expensive ($1250 for my back-most lower tooth, with three roots, in early 2003) and I imagine his rates are still very high. Nevertheless, I believe it was money well spent because the root canal has never come back to haunt me again. I don't think root canals are the types of procedures that one should skimp on. The procedure was relatively painless, and the office was equipped with (at the time) top-of-the-line equipment. Dr. Ribera was able to track the progress of his work simultaneously with the computer equipment. I can't speak of the insurance help because I had no insurance at the time. Overall Dr. Ribera is incredibly pleasant, friendly, and worked well with my regular dentist to coordinate the process!
