The dentist and his assistants incredibly nice people who are good at making you feel relaxed. They have done very good work. But there was one complication in using invisalign and getting bridge. I was a complex case, so used invisalign for a long time before doing bridge work. They hadn't done many invisaligns at that point. A white spot developed on my front tooth. Invisalign &/or bleaching may have caused it, or something else. They didn't know. That area of the front tooth eventually broke off (biting on potato chip!). They fixed it for free. But now I need to bleach more than is probably healthy for my teeth in order to match the whiteness of new teeth in the bridge.
About Hygienist: very nice and gentle; dentist himself does more complicated cleaning
