^^ agreed about the most important things on your face... i think its standard for them to ask, cuz i see my dentist all the time , i get my teeth cleaned on a regular basis probably like 4 times a year, he asks me every time i even asked him 3 days ago if he gets tired of asking me he said he has to... so i dunno.. maybe its just him.. i mean does it really matter i don't think so... they just want to kno for the paper work probably...
