"Milk teeth" of a foal are short and oval-shaped Incisors of a younger horse. 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 ...
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. After the age of five, age can only be conjectured by study of the wear patterns on the incisors, shape, the ...
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.
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.
The cheek teeth of elephants express this in a slightly different form with the vertical curtains of enamel coming in from the sides and meeting in the middle. [ 3 ] In horses and most equines the cross section of the tooth at the grinding (occlusal) surface shows the roughly circular or ovoid infundibulum as the incisor begins to wear. [ 4 ]

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.
The first, known as primary dentition stage, occurs when only primary teeth are visible. Once the first permanent tooth erupts into the mouth, the teeth that are visible are in the mixed (or transitional) dentition stage. After the last primary tooth is shed or exfoliates out of the mouth, the teeth are in the permanent dentition stage.
