Horses, like humans, have deciduous (baby) teeth that fall out and are replaced by permanent (adult) teeth. Realize that as a horse ages, the accuracy of determining its age by using the teeth, declines. The following information and pictures will help a horse owner identify the approximate age of a horse. Determining Age of Horses by Their Teeth Wayne Loch and Melvin Bradley Department of Animal Sciences. The art of determining the age of horses by inspection of the teeth is an old one. It can be developed to a considerable degree of accuracy in determining the age of young horses. Recognize the dental landmarks of older foals and young horses. You can accurately age a horse from newborn to 5 years of age. Landmarks in this period include the eruption of all the milk (deciduous) teeth, and their replacement by permanent, adult teeth, which is complete by 5 years of age%(47). Welcome to the AAEP!

You can be pretty accurate up to about 5 years of age, by looking at the horse’s front teeth. Just like human children, they lose their baby teeth at a pretty predictable pace. So, for example, horses lose their middle incisors (the front teeth) at 2 1/2 years, the ones next to the middle at 3 1/2 years, and the corners at 4 1/2 years. DETERMINING THE AGE OF FARM ANIMALS BY THEIR TEETH By GEORGE W. POPE, chief, Field Inspection Division, Bureau of Animal Industry CONTENTS Page Importance of determining the age of farm animals 1 Horses and mules 1Cited by: 2. determine approximate age and anyone can learn the basics. To use as a reference guide, Figures 1 and 2 indicate the names of the teeth. Figure 1. Figure 2. Incisors Horses under 5 years of age go through some very typical dental changes. With foals a good rule of thumb to remember is that their milk teeth, or deciduous teeth, erupt, or come in. Horses and Mules. The ordinary observer can readily learn to tell the age of horses or mules with considerable accuracy until the animals have passed their eighth year. Beyond this time even those who are experienced may find it difficult to determine the exact .
Horsemen traditionally use teeth to estimate a horse's age, but it's not foolproof. A very young horse's age is determined by which teeth are present and which he's losing. After that, age is determined by the wear, making accurate age estimation relatively easy only until the age of 9 or Aging Horses by Their Teeth. Estimating the age of a horse by examining its teeth is a common practice. For very young horses, eruption dates are useful, but in general, the place to start is examination of the occlusal surface of the lower incisors. Similar changes occur on the upper incisors, but it is typically easier to get a good look at. Additionally, horses who live in areas with sandy soil may wear their incisors more rapidly and give the appearance of being older than horses of the same chronological age who live on other soils. Stall-kept horses, who use their front teeth primarily to pull hay from a net or rack, usually show less wear of the incisors than pastured horses. cator used in horses under five years of age. Permanent teeth generally corne into wear three to six months after eruption. In this photograph, the left upper central deciduous incisor ("cap") is being pushed off by the underlying permanent.
