None of my seven have chipped a tooth grinding their teeth, but the sound of it makes me cringe! My baby hasn't started that yet, but I can think of at least three of my kids who have done this (probably more, but I can't remember it), and everyone has been fine. My baby has also gotten her teeth with one on the top and one on the bottom! She now has three, two on the top and one on the bottom!
