Abstract
Over time, horses have evolved both anatomically and in their eating habits as a result of domestication. Their dentition has thus changed, but it is still the imprint information that makes it possible to determine their age. In clinical veterinary practice it is necessary to know the structure and physiology of the oral cavity, the way the presence of abnormal dental order affecting horses manifests, and the proper way to perform a clinical examination of the cavity, so as to facilitate the use of preventive treatments and, in the event of an affection, reach an accurate diagnosis and then establish the appropriate treatment. It is worth noting that veterinary dentistry has been neglected by professionals who have allowed it to be invaded by empiricists or human dentists.
