Horses are diphyodontous, erupting a set of first deciduous teeth (also known as milk, temporary, or baby teeth) soon after birth, with these being replaced by permanent teeth by the age of approximately five years old. The horse will normally have 24 deciduous teeth, emerging in pairs, and eventually pushed out by the permanent teeth, which ...
Merychippus was the first equine to have the distinctive head shape of today's horses. The Miocene was a time of drastic change in environment, with woodlands transforming into grass plains. [7] This led to evolutionary changes in the hooves and teeth of equids.
Wolf teeth are small, peg-like horse teeth, which sit just in front of (or rostral to) the first cheek teeth of horses and other equids. They are vestigial first premolars , [ 1 ] and the first cheek tooth is referred to as the second premolar even when wolf teeth are not present.
Therefore, wolf teeth are commonly removed. [10] Horse teeth can be used to estimate the animal's age. Between birth and five years, age can be closely estimated by observing the eruption pattern on milk teeth and then permanent teeth. By age five, all permanent teeth have usually erupted. The horse is then said to have a "full" mouth.

A diphyodont is any animal with two sets of teeth, initially the deciduous set and consecutively the permanent set. [1] [2] [3] Most mammals are diphyodonts—as to chew their food they need a strong, durable and complete set of teeth. Diphyodonts contrast with polyphyodonts, whose teeth are constantly replaced.
Modified triadan system of dental nomenclature in the horse. The modified triadan system is a scheme of dental nomenclature that can be used widely across different animal species. It is used worldwide among veterinary surgeons. Each tooth is given a three digit number. The first number relates to the quadrant of the mouth in which the tooth lies:
The first of the permanent teeth to erupt are the permanent first molars, right behind the last 'milk' molars of the primary dentition. These first permanent molars are important for the correct development of a permanent dentition. Up to thirteen years of age, 28 of the 32 permanent teeth will appear.
