Brackets that I've had pop off in order of when they came off (left means my left, etc.):
Bottom left first molar (Sept 07, right after I got the braces put on)
Bottom right first molar (Sept 07, right after I got the braces put on)
Upper right central incisor (Oct 07)
Upper right lateral incisor (Oct 07, during adjustment)
Bottom right canine (Jan 08, during adjustment)
Bottom left canine (this past Tuesday)
Bottom right first bicuspid (today)
Is this a new record?

Oh, and for the record, I have not been eating caramels or anything else that is likely to yank at my brackets. My dentist suspects either that I have particularly non-sticky teeth or that my initial bonding had a bad glue run.
