Horses do not lose their front teeth in the same way humans do. They actually continue to erupt new teeth throughout their lives, replacing worn-down ones.
Here is a breakdown of their dental development:
* Foals: They are born with "milk" teeth, also called baby teeth, which typically start to erupt before birth.
* Around 2-3 years old: The permanent incisors start replacing the milk teeth.
* Around 4-5 years old: All permanent incisors are usually in place.
* Throughout life: Horses continually erupt new teeth to replace those worn down by chewing. This process can last until they are 20-25 years old.
While they do not lose their front teeth in the traditional sense, the shape and length of their incisors can be used to estimate a horse's age, especially in younger horses.
