Did the crown break, or just fall off? If it just fell off, getting it glued back is a five-minute job, and your dentist can probably do it on a walk-in basis between appointments. They make those adhesives in many grades, and your dentist will just use the next stronger one. On Fri, Aug 5, 2016 at 10:29 AM, James Propp <jamespropp@gmail.com> wrote:
Is it possible to design materials so that they'll fall apart (or change state in other useful ways) when stimulated by vibrations of a particular frequency?
I just had a temporary crown put on one of my teeth. The dentist used a weak adhesive (so that he'd be able to remove it a couple of weeks from now when the real crown is available), and the crown just broke (I'm guessing that the weak adhesive that he used was at least as much a factor as the scone I crunched).
Could there be a stronger adhesive that loses its adhesive virtue when you make it vibrate it just so? (Might dentists if the future say "Don't sing any loud B-flats for the next two weeks"?)
