WTF. Mine chipped last week. Tiny chip out of the bottom, left corner of my left, front, top tooth. When I put it as my status, other tooth-chip victims came out of the woodwork to express their sympathy. I am now passing that on to you. You are not alone.
Scott must have British teeth too. :)
I once heard an English orchestra conductor describe his view from the podium of a smiling hometown symphony chorus as "looking at a row of tombstones." Reference to British teeth and all, you know. He lives in the Bay Area now and has the straight white teeth which California law requires.
