I have heard they require you shadow for 40 hours with the dentist that writes your LOR. Do you know if that is true?I called them about this a few months ago and they said it was fine if the lor isn't from a general dentist. Mine is from an orthodontist as well.
As long as you have shadowing from a general dentist listed in your aadsas, they said it was fine.
All that matters is you have your LORs and your 40+ hours with a general dentist and 75+ hours with a general or specialty - whether they're separate people/dentists or the same, they don't care. So if dentist #1 you've shadowed for 100 hours and dentist #2 you've only shadowed for 15, but dentist #2 will write a better letter/knows you more personally, pick dentist #1 for proof of shadowing and dentist #2 for LOR. Probably less leg work for you if the LOR from a dentist also mentions your 40+ hours there though.I have heard they require you shadow for 40 hours with the dentist that writes your LOR.
