  • Equine dentistry is the practice of dentistry in horses, involving the study, diagnosis, prevention, and treatment of diseases, disorders and conditions of the oral cavity, maxillofacial area and the adjacent and associated structures.
  • Horses are hypsodont animals, which mean that their teeth continually erupt throughout their lives and worn away by grinding feed material at their occlusal surfaces.
    Therefore, each horse has both an erupted clinical crown and un-erupted reserve crown.
The horse usually has 24 cheek teeth, with 3 premolars and 3 molars in each quadrant of the mouth. Like the incisors, the premolars all have deciduous counterparts (caps) present at varying ages, which are shed with advancing age.

Horse Teeth Structure

The horse’s tooth is made up of four layers with different characteristics: pulp, dentin, enamel

Horse Hypsodont Teeth

Horses have very long hypsodont teeth (4 – 5 inches/ 10-12cm). Most of the tooth is a reserve hidden below the gum line

Triadan Tooth Numbering System – Horse Teeth

To avoid confusion when referring to specific teeth, a numbering system, called the Triadan system, was developed and is used worldwide

Horse Wolf Teeth

The horse´s wolf teeth (Triadan 05’s) are very small vestigial premolars located in front of the first cheek teeth

Horse Cheek Teeth

The horse´s cheek teeth are the teeth at the back of the mouth. (Triadan 06’s to 11’s) There are 24 cheek teeth (molars and premolars) in an adult horse

The horse’s tooth is made up of four layers with different characteristics: pulp, dentin, enamel, and cementum The pulp is the innermost layer and contains vital parts such as nerves and blood supply. This structure is soft and sensitive, and so it is protected by the outer layers.
