i went to dr.williams for a root canal. before he started the procedure he explained everything to me, and reassured me (as i was quite nervous) i felt no pain, no discomfort during the whole procedure. he is genuine and is gentle with his patients. i would defintely defintely recommend him -- he is been practicing for 38 years- you can feel he knows what he's doing when he's working on your mouth -- A + experience (never thought i would say that about a dentist)
