Lets see here.... I once blacked out at home and fell on my face, broke one of my front teeth half off. No tooth pain for that one though, the dentist just rebuilt it using that bonding stuff, it's been perfect for about 17 years now.
The closeest I've come to this is... A filling in one of my back molars disintegrated a few years ago leaving a huge hole. Hurt like hell, I'm not sure what broke it. Dentist simply re-filled it and all has been wine and roses ever since.
And pizza is good for your teeth. All that calcium in the cheese you know. 4 out of 5 dentists agree that ordering "double cheese" on your pizza keeps you on the road to good dental health.
