Why do horses crib?

Yup you know what I'm talking about! The horse that loves chewing the wood or really anything it can get its teeth on! Your stall doors or fences look like a mangled mess and your going to have to spill some cash to get them repaired or replaced! And your probably trying to get them to stop with most likely a cribbing collar. But do you think that is the answer? Do you know the root cause of the issue?
