I had an emergency with a tooth. Severe pain and my dentist told me it was due for a second root canal (retreatment). The endo's she recommended were out of network for me. I didn't want to go that route, but she suggested I find an endo who performed microscopic root canals. I checked the folks on my in network list and took a chance on Dr. Wollard. I have not met a more nice, professional endo in all my years. I had my procedure today, still some discomfort. That's due to all the infection that I had. He cleaned out, packed with antibiotics and prescribed antibiotics for me. The entire process was less than an hour. That's check in and check out, with the follow up appointment. I am recommending anyone I come in contact to Dr. Wollard. I rated the success a 3 because I haven't escaped the post op pain, but I'm sure that everything will turn out successful.
