At what age to horses lose their front teeth?

Horses don't 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's a breakdown of their dental development:

* Foals: They are born with "milk" teeth (also called "baby teeth"). These 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 don't 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.
