Hello, I just got a letter from dental school confirming my deposit they received. With it, there was another letter that says to collect "properly preserved, extracted human teeth procured form dentists in your locality." Does anyone know how many teeth this means, also do I just let them chill in my room or refrigerator til dental school starts? Just seems kind of wierd but I guess it must be normal. Also, it gives me two options to get them cleaned: 1. do them yourself by scrubbing and washing with detergent at home. or 2. use an ultrasonic cleaner. Do dentists have an ultrasonic cleaner so that I can just ask them if they can possibly do it for me? Let me know what you guys are doing and what you think I should do, thank you.
