Galvaynes Groove
Is a groove that appears on the outer surface of the upper lateral incisor
teeth. It appears at about 9-10 years of age at the top of these teeth and
develops down the tooth more as the horse ages. At 15 years it will have
developed more than a half of the way down the upper lateral incisors. By
20 years it reaches the bottom of the lateral incisor teeth. After 20 years old
the Galvayne’s groove gradually disappears from the top down and cannot
be seen in a thirty year-old horse.
