I have had nothing but good experiences with Dr. Mintz, and have had one pulpectomy and 5 root canals performed by him. He is very knowledgeable and skilled. The procedures aren't bothersome at all, unlike other places I have been where it's been absolute torture! He sings the entire time, off key (lol) which is not only funny but it really takes the edge off while you're sitting there. I do find it to be a little on the expensive side but completely worth it and I will never ever ever go anywhere else to have a procedure like this done again. I would highly recommend. Facilities at the Chicago Heights offfice are much nicer than Dyer, make the appointment there.
