Dr Paul Mahn was my regular denitst. After going regularly to see him I decided that my next 6 month check up I would go somewhere else. I was SHOCKED to learn that I had 14 cavities, one root canal, and possibly 2 more root canals. I was so confused becuz I was going to see dr mahn regularly. I went for a second opinion with the same results, each saying that couldn't see how my previous dentist (dr mahn) could have missed such large cavities (my x-rays with dr mahn were 6 months prior.) Going to a different dentist I now see newer equipment, better x-rays, and more in depth examining and a detailed monitoring of each tooth and the gums.
