Collecting teeth isnt that bad, if you call a few dentists they should be able to start collecting them for you. My advice to you is to not worry about having them in your hand the first day. Wait until they let you know what you need to do with them. We didnt need ours until this semester, which means if you picked yours up from the dentist in august you would end up holding on to them for 5 months- yuck. Let the dentist know you would like them to keep collecting during that time... it isnt that big of a deal, get as many as you can
