In reponse to "a little frustrating" It's too bad you had a bad experience with Dr. Rude. I too was referred by my regular dentist. I hate dental work of any kind and am afraid everytime I have to sit in the chair. I love Dr. Rude. I have had painful, horrible experiences with other endodontists and would never let anyone else BUT Dr. Rude do a root canel on my mouth again. I highly recommend him.
