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 ...
In 1756, when Washington was 24 years old, a dentist pulled his first tooth. [2] According to his diary, he paid 5 shillings (£0.25, equivalent to $12 in 2023) to a "Doctor Watson" for the removal. His diary also regularly mentioned troubles such as aching teeth and lost teeth. [3]
A young adult horse will have teeth which are 4.5-5 inches long, with the majority of the crown remaining below the gumline in the dental socket.

The labial half is made of enamel and resembles a crown, while the lingual half is made of dentin and resembles a root.
