I always wondered where the saying, "Don't look a gift horse in the mouth." came from, so I did a little research and found out what it really means.
The saying "don't look a gift horse in the mouth" originates from the practice of evaluating a horse's age and health by examining its teeth. When someone gives you a horse as a gift, it's considered impolite to inspect its teeth, as it implies you're questioning the value of the gift. The phrase essentially means to be grateful for a gift without scrutinizing it too closely.
our proverb says teeth, not mouth. so we don't need to research, lol.
