The term comes from the process of filing down the sharp points and edges of a horse's teeth. This process, called floating, is done by a veterinarian or a qualified equine dentist using a specialized tool called a float.
Here's why this process is called floating:
* Smoothness: The tool used to file down the teeth is designed to create a smooth, even surface on the teeth. This resembles the smooth surface of water.
* Elimination of Sharp Edges: The sharp edges and points on a horse's teeth are filed down to create a smooth, "floating" surface.
So, while the term "float a horse's teeth" might sound a little odd, it accurately describes the process of smoothing out their teeth to prevent pain and discomfort.
