'''Dental Formula'''
:The formula for '''deciduous''' teeth: 2 (I3/3 C0/0 P3/3)
:The formula for '''permanent''' teeth: 2 (I3/3 C1/1 P3-4/3 M3/3)
The molars have enlarged surfaces and higher [[Enamel Organ#Crown|crowns]]. They have delayed [[Enamel Organ#Root|root]] development and complicated folding of [[Enamel Organ#Enamel|enamel]].
'''Canines'''
:The canines are '''rudimentary''' and are located in the '''diastema'''. The size of the [[Enamel Organ#Root|root]] is proportionally larger than the [[Enamel Organ#Crown|crown]].
'''Molars'''
:The molars have enlarged surfaces and higher [[Enamel Organ#Crown|crowns]]. They have delayed [[Enamel Organ#Root|root]] development and complicated folding of [[Enamel Organ#Enamel|enamel]].
'''Incisors'''
:Incisors have high [[Enamel Organ#Crown|crowns]] and folded [[Enamel Organ#Enamel|enamel]] surfaces. Their [[Enamel Organ#Root|roots]] converge.
A horse's '''Wolf tooth''' (PM1) is often lacking. Molars and Premolars form a continuous surface. Premolars have a high rate of wear and continually erupt. The upper teeth are wider than the lower. There is no infundibulum in the lower teeth.
