How much damage does opening a bottle of beer with your teeth do?

For couple years ive done this as a party trick, ive grabbed a bottle and bitten down on the cork to open it. For the record nothing has happened to me or my teeth. Had routine checkup with a dentist a week back and she told me my teeth are in good condition. But that visit made think of this party trick of mine, and about how damaging it could be. I decided to stop it there, but if anyone has any stories or anything, id like to hear.
