My boy was a cribber. I met him as a 7yr old (both of us), got him as a 16yr old, & lost him as a 23yr old. He cribbed throughout that entire time, to the dismay of the barn owner. I never in a million years would have considered surgery for him, but we tried just about every other cure out there, & nothing worked. It's been explained to me by several different sources that the wind sucking is actually a horsey equivalent to getting "high". I'm not sure exactly how it works, but I know that it is most certainly an addiction, & can be near impossible to break. He cribbed just as badly with or without his collar, so as much as I disliked it, I learned to just live with it.
As far as teeth go, unfortunately, my boy had a tooth that was completely broken in half, probably from the cribbing. That made meal times quite messy when there was grain involved!
