What is floating a horses teeth? It's a dental procedure preformed by a large animal veterinarian. The purpose of floating is to remove sharp points that have developed on the teeth, and encourage an even grinding pattern to aid in digestion. I find it interesting that a horse's teeth never stop growing. Itâs kind of like having a giant hamster!
