I went to Dr. Dach's for a second opinion when a dentist I went to told me I had 7 cavities! Dr. Dachs advised that I had none and his staff was able to clean my teeth without my experiencing any pain. Having very sensitive teeth, I always hated to go to the dentist. His staff was able to use a numbing agent on my tender gums and cleaning was painless. I can't say enough wonderful things about Dr. Dachs and his staff. They are top notch!!
