Dr. DiAndreth has done 4 root canals for me. He did a great job. Very quick and thorough. I have had a RTC with a general dentist and the experience was nothing like this. That procedure was somewhat painful and very long. And I ended up losing the tooth. I felt no pain with Dr. DiAndreth and he completed 2 RCT's at a time. I highly recommend him. I will never again have another RCT with a general dentist. Going to a good specialist makes all the difference. The entire office staff is very nice and accomodating. Great practice!
