Video: Determining The Age Of A Horse By Teeth
The oldest and most common way to determine a horse's age is by teeth. After the milk teeth are replaced by permanent ones, the latter grow, grind and age, age and grind, grow …
Horses' teeth are distinguished by the fact that they are all long-coronal (both incisor and molar); in stallions, as a rule, canines are located between the incisal and molars, but in mares canines can be an exception; Horses have 12 incisor teeth in total - six lower and six upper. Stallions have 40 teeth, while mares only have 36, as they lack canine teeth.
As horses age, the shape of the teeth and even the jaw changes. In order not to engage in abstract reasoning, we present a drawing that explains how the teeth of a horse look and the dependence on its age.
Horses older than 5 years of age change the shape of the chewing surface of the teeth and the angle of inclination of the teeth when closing. Up to 9 years old, the shape of the chewing surface of incisal teeth is oval, from 9 to 16 years old it is rounded and rounded, from 17 to 20 years old, triangular, over 20 years old, back oval.
In young horses, the upper and lower incisors meet almost at right angles. With increasing age, the outer surface of closed teeth resembles an acute angle. At 7 years old, a notch is indicated on the upper edges of the incisal teeth above the edges of the lower edges. At 9 years old, this notch is clearly marked and the deepest notch is at 12 years old.
