Dental procedures are performed on horses by a process called "floating." Flaoting means to smooth or contour your horse's teeth with a file (called a "float"). Unlike human teeth, a horse's teeth keep growing. Periodically throughout the horse's life, sharp edges develop on the teeth, making it painful and difficult to eat. Horses like humans do have two sets of teeth in their lives. Typically they will have lost all their baby teeth by age 5. Adult horses will have between 36-44 permanent teeth.
