We recently got our gelding. Found out he has been passed around to at least 3 homes this year. No one was sure of his age. Could someone help me.? We was told between 7 and 13. Here are some pics.

  • 5 year old: Adult teeth newly in wear. Incisors meet at a near vertical angle. Teeth are upright and blocky. The chewing surface of the incisors is concave. The shape of the tooth is cross section is oval.
  • 5-9 years old: Cups are present on the chewing surface of the incisors. These grow out by 9-10 years of age, leaving lighter "marks", which are gone by 12 years of age.
  • 7 years old: The upper corner incisor has a spur or hook where it overhangs the lower incisor. This is known as the "7 year hook" because it disappears by 8 years of age. However, this is an inconsistent finding and may be present on one side of the mouth but not the other.
  • 10 years old: Galvayne's groove appears as a brown-colored mark at the gum line of the upper corner incisors. By the age of 11 years the chewing surface of the incisors is flat. The shape of the tooth in cross section is round. Stars appear (from 8-10 years) on the chewing surface of the incisors and become more distinct with age.
  • 15 years old: Incisors meet at a near 90 degree angle. Teeth are elongated with a chisel like edge. Galvayne's groove is now halfway down the upper corner incisor.
  • 20 years old: Galvayne's groove has disappeared from the gum line of the upper corner incisor.


This help any?
