The molars have enlarged surfaces and higher [[Enamel Organ#Crown|crowns]]. They have delayed [[Enamel Organ#Root|root]] development and complicated folding of [[Enamel|enamel]].

===Incisors===
Incisors have high [[Enamel Organ#Crown|crowns]] and folded [[Enamel|enamel]] surfaces. Their [[Enamel Organ#Root|roots]] converge.

===Premolars===
===Premolars===
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.

The teeth from the second premolar caudally are referred to as cheek teeth.

The '''Galvayne's Groove''' is a brown groove on the upper corner incisor teeth and indicates that the horse is over 10 years old. At 15 the groove will be approximately half way down the tooth; At 20 the groove will run down the whole tooth; Over 20 the grove begins to disappear; At 25 the groove will only be visible on the bottom half of the tooth. At 30 the groove will usually be gone.
