Teeth floating is necessary for mules. The process is to “file” down points that develop over time in the mule’s mouth. Equine teeth are open-rooted, which means that they grow continuously and rely on chewing to keep them ground down to the correct length. The top set of molars is wider than the lower set; equines chew in a circular motion, which means that over time if the mule has an uneven bite, sharp spurs can develop. Floating is the process whereby the spurs or spikes are “floated” or rasped down with a dental file designed for use in equines. Age is not always a factor; have your mule’s teeth checked during regular vet visits. Floating your mule’s teeth is very important in order to prevent oral pain and to ensure your mule is healthy overall.
