Why are people long in the tooth?
Because old horses are. Horses have open rooted teeth that grow through their lives. (Some old horses will outlive their teeth - at which point they really need special food so they can gum it properly).
So, the saying "long in the tooth" originally referred to horses and then came to refer to people (and dogs, cats, etc).
