A horse is usually smooth mouthed by what age?

A horse is considered smooth mouthed typically by the age of 11 years. This term refers to the absence of the jaw teeth that are often worn down and effectively result in a more level or smooth surface, making it difficult to differentiate age based on dental characteristics.

The dental examination of a horse involves looking at the incisor teeth, which change over time and can provide clues to the horse's age. As horses age, their teeth undergo wear and changes in shape, leading to the "smooth mouth" appearance around this age range. By 11 years, the horse will have lost the last of its baby teeth and developed a full set of permanent adult teeth, which become increasingly worn, contributing to that smooth impression.

This knowledge is crucial for evaluating a horse's age and understanding its overall health and suitability for various activities.
