Previous review may be isolated experience
I have worked in dental offices for nearly 20 years in Atl area, including working for endodontic (root canal specialists). I have worked in dental offices that refer quite frequently to Dr. Whitner who accepts many insurances unlike most root canal specialists. Of the hundreds of patients we referred to Dr. Whitner, none every complained and many were quite happy. Dr. Whitner's root canals appeared to be done quite well. Also, while I do not claim to be an expert on the topic, I believe that dry sockets come from extractions and not root canals. With root canals, post-operative pain is extremely common and can usually be relieved with Advil.
