Young horses have a total 24 deciduous or milk teeth – 12 incisors and 12 premolars or grinders. Mature male horses have 40-42 permanent teeth and mares have 36-40 depending on the number of canine teeth present..
What are the different types of teeth in horses?
Their teeth are divided into two major sections: the incisors, which are the teeth seen in the front of the horse's mouth, and the cheek teeth, made up of the premolars and molars. The molars and premolars are lined up tightly against each other, creating the appearance of one chewing surface..
What is the anatomy of a horse's teeth?
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..
What is the pattern of a horse's teeth?
Their teeth are divided into two major sections: the incisors, which are the teeth seen in the front of the horse's mouth, and the cheek teeth, made up of the premolars and molars. The molars and premolars are lined up tightly against each other, creating the appearance of one chewing surface..
What is unusual about equine teeth?
The most basic differences between a horse's teeth (an herbivore or plant eater) and the teeth of humans or dogs or cats (omnivores and carnivores) is that a horse's teeth are not completely covered in enamel, and what is visible in the mouth is not meant to last the horse's entire life..
The age of horses, donkeys, and mules can be estimated by examining the eruption and wear patterns of the teeth. Figures 7 through 9 provide a usable reference to help the accredited veterinarian approximate a given horse's age.
THE HORSE'S MOUTH The forward teeth, known as incisors, function to shear off forage. The cheek teeth, including the molars and premolars with their wide, flat, graveled surfaces, easily grind the feed to a mash before it is swallowed. Like humans, horses get two sets of teeth in their lifetime.
The adult horse usually has 36-42 teeth but can have up to 44 teeth as a mature 5 year old. The front teeth (incisors) are used to grip and cut the grass. The back or cheek teeth (premolars and molars) are used to grind up the food.
Horses wear their teeth down about 2.5 millimeters per year, on average, he said. Young horses develop and erupt 24 deciduous (or baby) teeth, including the incisors and premolars. Starting at about 1 year of age and continuing approximately through age 5, horses sequentially erupt 36 to 44 permanent teeth.
Horse Mouth Anatomy
The horse’s mouth anatomy is quite different from ours because they evolved to eat tough fibrous plants such as grass, and their mouth adapted to this diet
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 Canine Teeth
The horse’s canine teeth (Triadan 04’s) are located between the incisors and premolars. They were originally “fighting teeth”
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
How Does A Horse Chew?
Horses chew in a repetitive, cyclical motion with 3 phases: the mandible drops (opening stroke)

What are horse teeth?
Horse teeth refers to the dentition of equine species, including horses and donkeys
Equines are both heterodontous and diphyodontous, which means that they have teeth in more than one shape (there are up to five shapes of tooth in a horse's mouth), and have two successive sets of teeth, the deciduous ("baby teeth") and permanent sets
What is equine dental anatomy & physiology?

12 Equine Dental Anatomy and Physiology The anatomy of the oral cavity and its supporting structures including nerve supply and normal variations
Gross anatomy of the head including sinus structure, cranial nerves, and oral cavity
Histological anatomy of the teeth / morphology
The modified Triadan system of dental nomenclature
Why do Equine teeth change morphologically?
Even the permanent dentition is subjected to continuous, dynamic, morphological changes due to massive occlusal wear and the compensatory tooth eruption that is necessary in herbivores
Consequently, it is not surprising that the normal equine oral anatomy of structures shows a wide range of variations
The equine tooth—like that of other animal and human species—is comprised of four layers: pulp, dentin, enamel, and cementum. The innermost layer, the pulp is “basically the heart and brain of the tooth,” Whittle said.

Evaluation of a horse's bone and muscle structure
Equine conformation evaluates a horse's bone structure, musculature, and its body proportions in relation to each other. Undesirable conformation can limit the ability to perform a specific task. Although there are several faults with universal disadvantages, a horse's conformation is usually judged by what its intended use may be. Thus form to function is one of the first set of traits considered in judging conformation. A horse with poor form for a Grand Prix show jumper could have excellent conformation for a World Champion cutting horse, or to be a champion draft horse. Every horse has good and bad points of its conformation and many horses excel even with conformation faults.
