I knocked a few teeth out playing rugby, forgot my gum shield but thought I would chance it. Took a boot in the mouth teeth came out whole but the coach knew what to do - clean them off, soak them in milk which he got from the clubhouse and then push them back into the holes in the gum. Whisked off to the dentist holding my teeth in place with my hand, they glued some plastic over the teeth and to the roof of my mouth and told me to eat soup for a month. Tape taken off and x-rays showed that the teeth started to bed back in. Rugby and footy career over from that point onwards, as was biting into apples.
