How many teeth do male and female horses have?
A mature horse may have 36 to 44 permanent teeth. Every adult normally has 12 incisors at the front and 24 cheek teeth used for grinding. The variable teeth are the four canines and up to four first premolars commonly called wolf teeth.
Male horses more often develop four visible canine teeth, bringing a common total to 40 before wolf teeth are counted. Mares often have absent or much smaller canines, so 36 is a common baseline. These are patterns, not absolute rules. A mare can have canines, a male can lack one or more, and wolf teeth may occur in either sex.
The Merck Veterinary Manual overview of equine dentistry describes 11 actual or potential tooth positions in each dental arcade when canine and wolf tooth positions are counted. A veterinary oral examination is the reliable way to document what an individual horse has.
The main types of horse teeth
- Incisors: Six upper and six lower front teeth help grasp and crop forage.
- Canines: Located in the bars between incisors and cheek teeth. They are common in geldings and stallions and often absent or reduced in mares.
- Wolf teeth: Small first premolars, most often in the upper jaw. They are not extra incisors and are different from canine teeth.
- Cheek teeth: Premolars and molars form the grinding rows that process fibrous feed.
Horses have long-crowned teeth adapted to prolonged forage chewing. Tooth surfaces wear while more crown gradually erupts. Wear is not always even, which is one reason sharp points, hooks, overgrowths, fractured teeth, periodontal problems, and other abnormalities may develop.
Why a complete dental examination matters
A quick look at the incisors cannot reveal the entire mouth. A complete examination by a veterinarian typically involves safe restraint, an oral speculum, good lighting, and palpation or visualization of the cheek teeth and soft tissues. Sedation may be appropriate so the horse can be examined thoroughly and handled safely.
Floating means reducing selected sharp enamel points or overgrowths when clinically indicated. It should not be treated as an automatic cosmetic procedure or performed aggressively. The veterinarian evaluates the whole mouth, the horse's age, use, diet, previous findings, and current signs before deciding what work is needed and when.
Young horses may need monitoring as deciduous teeth are replaced. Older horses may develop loose, worn, missing, or diseased teeth and may require changes in forage form or feeding management. The right examination interval is individual, so ask your veterinarian to set a schedule rather than relying on one universal calendar.
Signs that deserve veterinary dental attention
- Quidding, or dropping partially chewed feed
- Difficulty chewing, slow eating, or unexplained weight loss
- Bad odor, facial swelling, nasal discharge, or oral bleeding
- Head tossing, bit resistance, or a new change in ridden behavior
- Whole grain or unusually long forage fibers in manure
- Choke, recurrent colic concerns, or a sudden inability to eat normally
These signs are not specific to one dental problem. Contact your veterinarian promptly, and treat choke, heavy bleeding, severe swelling, trauma, or inability to eat or drink as urgent.
Frequently asked questions
Do all male horses have 40 teeth?
No. Forty is a common count when four canines are present and wolf teeth are absent. Individual horses may have fewer teeth, wolf teeth, missing teeth, retained deciduous teeth, or extra teeth.
Do mares have wolf teeth instead of canines?
No. Wolf teeth are first premolars, while canines are a different tooth type. Mares can have either, both, or neither, although canine teeth are less common and often smaller in mares.
Should every wolf tooth be removed?
No. Removal is a case-by-case veterinary decision based on position, size, oral health, tack interaction, clinical signs, and the risks of the procedure.
Can a horse's age be read exactly from the teeth?
Dental features can support an age estimate, especially in younger horses, but individual wear, diet, management, and variation reduce precision as horses age.
