This is an illustration of a 1-year-old horse’s top and bottom teeth with his mouth open. This age is also known as a yearling.
When viewed from the front, the true yearling at 12 months old will have all of the deciduous teeth erupted and in wear. Laterally, the corner incisors from the upper and lower arcade will not be in contact. The central and intermediate incisors will have a longitudinal dental star, whereas the corner incisor will not.
The first permanent molars might start to appear at this age.
