The Age of Your Horse
This poem is taught to aspiring dental technicians in order to help properly age a horse for a client:
To tell the age of any horse
Inspect the lower jaw of course;
The six front teeth the tale will tell,
And every doubt and fear dispel.
Two middle nippers you behold
Before the colt is two weeks old;
Before eight weeks two more will come
Eight months: the corners cut the gum.
At two the middle "Nippers" drop:
At three the second pair can't stop;
When four years old the third pair goes,
At five a full new set he shows.
The deep black spots will pass from view
At six years from the middle two;
The second pair at seven years;
At eight the spot each corner clears.
From the middle "Nippers" upper jaw
At nine the black spots will withdraw.
The second pair at ten are bright;
Eleven finds the corners light.
As time goes on the horsemen know
The oval teeth three-sided grow;
Then longer get - project before -
Till twenty, when they know no more.
-Anon

You can also view the incisors from the side profile to determine a horse's average age range. As the horse ages, the angle of the incisors changes and becomes more severe.
