Dental anatomy of horse

What is the dental formula of a horse?
There are generally 40 teeth in the mouth of an adult horse.
The so-called dental formula for each hemi-arch includes: 3 upper and 3 lower incisors, 1 canine above and one below, 3 premolars above and 3 below and finally an equal number of molars.
The total, multiplied by 2, gives the result of 40 teeth..
What kind of teeth do the horse have?
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..
As with other adult mammals the horse has four distinct types of teeth – incisors, canines, premolars and molars.
The surface of the teeth in contact with the opposing ones is known as the occlusal surface.
The horse's upper jaw is wider than its lower jaw.
As a result, the outer aspect of the upper teeth don't directly contact the lower teeth.
Likewise, the inside surface of the lower teeth don't directly contact the upper teeth.
Both of these factors result in sharp points over time.
