*Horses can be aged by their teeth

Horses can be aged by their teeth. At 2 and a half the first permanent incisor will erupt; At 3 and a half the second permanent incisor will erupt and at 4 and a half the third permanent incisor will erupt. Over 5 years of age the folding of the enamel ring ('''infundibulum''') can indicate age. There is a 7 year hook and over 13 years of age a '''dental star''' will be present.

The Galvayne's Groove is a brown groove on the upper corner incisor teeth and indicates that the horse is over 10 years old
