Well joost, to be extra clear... someone would always check the horses teeth in selling/trading to determine how OLD (and also how healthy) the horse was so they could determine if it was being sold at an honest price. The saying came about because, well, if someone gives you a horse as a GIFT it would be rude to check it's teeth... at least in front of the giver. After all, a gift is free; if the recipient did not pay for the horse, then why should he nitpick about its age, health or other features?
