|Check TeethPremolars: The first three teeth on
each side of the jaw are called premolars. Deer grow two sets of premolars. The first set
appear in fawns and last until the deer is about 1-1/2; years old, when permanent adult
premolars push out the baby premolar teeth. An important characteristic of the first set
of premolars is that the third premolar has three crowns or cusps. When the
permanent teeth come, all premolars have just two cusps.
Molars: The fourth, fifth, and sixth cheek teeth are
the molars. Deer only grow one set of molars. Generally, six-month-old deer have only one
molar when they enter the fall hunting season. Therefore, six-month-old deer usually have
only four cheek teeth. By 1-1/2; years of age - the second fall - the second and third
molar have erupted through the gum, though the last cusp of the third molar may still be
below the gum line. All six molars and premolars are fully erupted by 2-1/2; years.
The vast majority of deer in North Dakota are 2-1/2; years
old or younger. To determine the age of animals in older age classes we need to look more
closely at tooth wear.
