The expression is "Don't look a gift horse in the mouth."
People who buy and sell horses, can tell the age and health of a horse by examining the horse's mouth. However, if someone gives you a horse, you should not examine its mouth to determine its value, simply accept the gift.
So the expression means, "If someone gives you a present, do not try to determine what it is worth. Just accept the gift and say, thank you."
Actually its "dont look a gift horse in the mouth". It means dont judge a present somone gave you. This came from when people gave horses as gifts. The gift horse was usually old, and you can tell a horses age by looking at its teeth.
