Eric Ranta is great, very easy-going and personable dentist. As I have been a patient of his for a while, I was particularly impressed with his obligation to the patient. The process of explaining all the x-rays, as well as what he was doing and why, really contributed in my confidence in him.
Also, I do not know if he uses a special anesthetic, but my jaw was starting to tingle before he even took the needle out. I had a root canal and actually fell asleep during the majority of the operation (and that's without gas).
If you're looking for a good dentist, Ranta came recommended to me by three friends, and he's the best I have ever had. Treat yourself, give him a ring and see if he is taking new patients, and if so, get yourself in a chair.
