Had several expensive 700$ crowns put in by Dr. Lo. Which, upon switching dentists, i discovered had open margins... basically rendering them useless and susceptible to decay. I had to fork out another $800 each to have them redone properly. Dr Lo could never muster enough manners to say hello before he would stick his fingers in my mouth. Nor would he explain anything to me, or answer my questions.... The only reason I continued to go to him is his assistant - who was helpful and tried to make up for his shortcomings.
