An adult horse’s teeth are hypsodonts (long teeth). The horse’s lifetime can take advantage of the teeth that are below the gum’s surface and will appear and emerge. Chewing coarse forage wears down the horse’s tooth and a new one will grow to replace it. A horse’s teeth are about 4 inches long, with most of the tooth hidden below the surface of the gums.  By considering the average wearing down and replacement of tooth material, experts have calculated that horses have about 25 years of use out of their adult teeth.   As the tooth begins to run out, senior horses become prone to dental problems such as gum disease, diseased roots, fractured teeth, or loose teeth.
