A decade or more I had a dentist that stayed towards the front of the technology curve, and he had an argon laser that he used for some fillings. My memory is that they were small fillings and he did it without pain killers, there was no whine from the drill, etc. I think he needed to "rough up" the hole that the laser made, which was done with the drill thing at low speed. I really liked him, but there was a combination of his location being inconvenient, and one of his dental techs was terrible, so I switched.
