Why flossing is bad

I was flossing last night, trying to get a bit of meat out from between a couple of molars when the floss got stuck. So I was pulling down on the floss when it came free with a jerk and at the same time there was a rattling sound from something falling into the handbasin. I reached into the handbasin and picked up the noisy object, looking at in astonishment, then I looked in the mirror and bared my teeth. There was a gap on one side which hadn't been there a few seconds ago.

Apparently a cavity had developed and the tooth had decayed underneath the filling and it had become weak enough that with just the right pressure in just the right place the crown of the tooth snapped right off.

I called my dentist's office, and even though it was 8pm, he picked up. I told him what had happened and he said to come in first thing in the morning. I spent almost two hours this morning in the chair getting an enamel crown put on. What a way to start my RDO Friday and a 3-day weekend.

And now, here's a picture :P
