Dr. Mathew Rowan is nice and seems intelligent. The office is pretty rushed. I had mouth pain in September 05 and he took xrays and did deep cleaning on the top teeth and gave me tetracycline. It seemed to help. But a month later the pain came back with a vengence. On a Friday in early November, he took another xray and said that it was an absess in my back lower tooth. He said I would need to have a root canal and it was "going to be one of the hardest root canals" He continued with the scheduled deep cleaning of the bottom teeth. He prescribed me penecilin and vivaden. I cried during the procedure because he did not have any pain medication besides numbing. My mouth was so sore that I could barely open it. After the procedure, my jaw has gotten really swollen, it hurts to swallow and of course I can't chew anything. I have been in more pain then before 9/10 and the dentist on call did not return my call over the weekend. It is Sunday afternoon and I have called in sick for tomorrow because I am still in 9/10 pain. I called another Comfort Dental Office and the doctor on call said that the penecillin takes 48 hours to start to work. So I decided to go on line to see what else in available.
