My goal is 150 hours of dental shadowing and 500 hours of volunteering.
However I'm only at 116 hours of dental shadowing and a little over 400 hours of volunteering and it looks like that'll be what I have when I submit my application.
Honestly the only two schools you need more than 100-110 hours of dental shadowing is for VCU and they require 150 hours. The only school you need more than 400 hours of volunteering is ASDOH and they want at least over 400 hours but preferably 500+ with a lot of "unique" volunteer experiences. If you're not applying to either of those two schools then 100 shadowing/400 volunteer should be the standard IMO. With that said, I think volunteer hours are more important than shadowing hours. Some dentists I shadowed I didn't learn a single thing while I was there.
