Aging By Teeth – 25 – 30 plus years (Senior Horses)

Reviewing these images is a long process if you go through the whole set. The idea is to notice all the differences and variability seen within each age. Then, as the age becomes greater, notice the increased variability. Also, note that some horses’ left and right sides are different, yielding a different age. The difference is caused by the horse’s tongue movement, jaw movement or both. The image data is the evidence I give for the horse’s age.

I call this group between 25 and 30+ years the “Senior Horses.”

25-year-olds

  • “Galvayne’s groove” is an indentation (or groove) that occurs on the upper corner incisors (103 and 203).
  • It is located on the labial surface and parallels the front and back edge of the tooth.
  • Between 10 and 20 years it will progressively extend the length of the tooth.
  • Between 21 and 30 years it will progressively disappear starting at the gum line until it is gone by 30.
  • The groove at the gum line slightly disappears along the length of the tooth starting at the gum line and is about half gone in the 25th year of eruption.
  • “Galvayne’s Groove half gone at 25.”
