The Aging Project – Left Lateral View

Things to look for
  • The angle of the teeth from vertical to more horizontal.
  • The appearance of a groove on the upper corner incisor #203 called Galvayne’s groove.
  • The inconsistencies while looking at just one identifying mark (angle of teeth, shape of teeth, groove along the side of the upper corner incisor)
  • The position of the tongue behind the incisors – how it is pressed up against them, how it can be the cause of the movement of the incisors away from vertical in older horses.
  • The relaxed space between the incisors in many of the horses.
  • The way the tongue rests against the canines as the factor behind the shaping of the canines into a dagger shape.
