Usually they have a replacement within 24 hours. Mine seems to shed his teeth every couple months, I think. Haven't really kept track, but don't worry about it. He probably already has a new tooth as I'm replying now.
just wait til they get relly big and we have huge teeth layin on the bottom of our tanks. then we can show people theyre teeth and watch theyre jaws drop. can i get a he** yeah?!?!
