In the past 20 years that I have been coming to Dr. Rosenthal, he has performed root canal therapy, extraction & apico's on my teeth. He is extremely knowledgeable in each of these areas. The worst part for me when going to the dentist, is getting the anesthetic injection. It's usually so painful, but Dr. Rosenthal takes that worry right out of the picture. He has such a gentle technique, I have never felt any pain with his injections. All my experiences have been pleasant and comforting with Dr. Rosenthal, and when in need, I will return for the next 20 years.
