long in the tooth: Idiom Meaning and Origin

The idiom "long in the tooth" is a common expression used in English conversation and writing. It is often used to describe someone who is old or aging. This idiom has been in use since the 17th century and has evolved to have a more figurative meaning over time.

The phrase "long in the tooth" comes from the fact that as horses age, their gums recede, making their teeth appear longer. Experienced horse traders of the past would often inspect a horse's teeth as a way to estimate its age and overall health. The longer the teeth appeared, the older the horse was believed to be. This association between age and tooth length gradually gave rise to the idiom.

As the idiom entered into everyday language, its meaning shifted to describe people who show signs of age or are past their prime. It suggests that they may have outlived their usefulness in some sense. The idiom is frequently used to refer to older individuals, although it can also be used humorously or in a lighthearted manner to describe anyone who displays signs of aging.

The idiom "long in the tooth" is well-known and understood in the United States. It is used both in informal and formal settings, appearing in literature, media, and everyday conversations. While its origin lies in the world of horse trading, the idiom is now primarily used figuratively to express the concept of aging.
