Maintaining Healthy Horse Teeth: 5 Things You Need to Know About Your Horse’s Teeth

5 Essential Healthy Horse Teeth Facts

Know the signs of tooth discomfort and common dental problems in horses

Just as important as their hooves, joints, and coat health, your horse’s teeth require regular care and maintenance. The health of your horse’s teeth and gums tells you a lot about their overall health and wellness.

In this blog, we provide facts and information that many people do not know about horse teeth. As always, please consult your veterinarian with any questions about your horse’s teeth.

Like many aspects of horse care, achieving healthy horse teeth requires periodic maintenance to ensure your horse lives its healthiest life. Keep in mind these 3 reasons for monitoring your horse’s teeth:

  1. Healthy horse teeth mean it’s easier to eat and absorb essential vitamins, minerals, and nutrients.
  2. Healthy horse teeth mean your horse is not in hidden discomfort. (Remember your horse is adept at hiding discomfort.)
  3. Healthy horse teeth mean your horse can get enough calories to maintain weight and fuel itself for training, competition, and daily life.

Head shaking, rearing, fighting the bit, and acting out can be signs of dental problems in horses. Pay attention to any changes in your horse’s behavior and when in doubt, contact your veterinarian for a full exam and dental check-up.

Make sure you know these 5 horse teeth facts and dental care.

1. You Must Routinely Float Your Horse’s Teeth

We go to the dentist to get our teeth cleaned. Horses go to the veterinarian to get their teeth filed. That’s right — your horse’s teeth never stop growing!

Luckily, horse teeth don’t have nerves, so it’s not a painful process when your vet floats or files them. However, vets usually sedate horses before starting the procedure. Otherwise, your horse could toss its head, and the file could injure their mouth or teeth.

Since horse teeth grow about 1/8-inch per year, you should aim to float their teeth annually. 

Equine dentistry is essential for healthy horse teeth because horses eat in a side-to-side motion, and their teeth don’t always wear down evenly. This chewing routine means the teeth can develop sharp points, causing pain and a range of dental problems in horses.

2. Geldings Usually Have More Teeth Than Mares

Geldings (and stallions) have about 40 teeth as an adult. In contrast, mares typically have less than this, ranging from 36 – 40 teeth.

The reason that mares often have fewer teeth is that it isn’t common for them to grow canine or bridle teeth.

Regardless of how many teeth a gelding or mare ends up having, their average tooth length is 4 inches. You might be wondering—how do horses in the wild manage their tooth length without a veterinarian to float them?

Horse teeth grind down naturally when they eat. Nevertheless, wild horses likely experience more mouth pain than those with floated teeth due to sharp edges that can form.

3. Foals Have Baby Teeth

Just like us, horses have 2 sets of teeth. Most of their incisors and premolars appear within the first couple of weeks of birth. The third incisors (corner teeth) are the last to grow in, which happens by your horse’s 9-month birthday.

Horses have long lives, so their adult teeth aren’t in a rush to grow. Wolf teeth appear at around 5 months, and select permanent molars and incisors begin growing during your foal’s second year of life.

However, canine teeth don’t grow until your horse reaches 4 or 5 years of age.

Because horses have such distinct phases of teeth growth, as well as deterioration as they grow older, it’s possible to accurately determine your horse’s age based on their teeth.

4. Horses Use Their Teeth for Different Purposes

Another horse teeth fact! Horses are herbivores. But even though they don’t eat meat, their teeth serve different purposes.

Incisors: help a horse bite grass. Horses have 6 upper incisors and 6 lower incisors.

Canine (Bridal): used for fighting between males. Many mares don’t have canine teeth.

Wolf: like humans, these teeth don’t serve a purpose, and sometimes veterinarians need to extract them to prevent issues.

Premolars and Molars: grind up food to aid digestion. Horses have a total of 24 premolars and molars.

5. Horses Can Have a Range of Dental Issues

If you wait until you have a senior horse to start tending to their teeth, you’re setting your horse up to have many potential health issues during their life.

That said, older horses have an increased risk of suffering from dental problems since their tooth structure begins to deteriorate. Furthermore, young horses under 5 years old need more attentive dental care because their teeth change so quickly.

Regular dental care is a must to maintain healthy horse teeth, regardless of age. However, if your horse is under 5 or older than 20, they may need multiple dental care visits per year. Be proactive with these dental visits, and don’t wait until your horse shows signs of tooth or gum soreness.

Symptoms of Dental Problems in Horses

If your horse is suffering from a dental problem, they often display several signs that you should keep an eye out for:

  • Lack of interest in eating
  • Weight loss
  • Halitosis (bad breath)
  • Quidding (when they drop food as they eat)
  • Opening their mouth wide when chewing or displaying other signs of having difficulty while eating
  • Nasal discharge from only one side of the nose
  • Tilting their head, especially when you ride them

Types of Dental Conditions in Horses

Maintaining healthy horse teeth isn’t straightforward, so you should call your vet if you suspect your horse has an issue with their teeth. However, to help you prepare for the types of dental problems your veterinarian may diagnose your horse with, here are some of the most common issues.

Shear Mouth: A condition that produces extra sharp teeth because there’s a greater than normal width difference between the horse’s upper and lower jaws. Senior horses have a higher chance of having this problem.

Step Mouth: Horses with step mouth have molars that look like a staircase because they differ in height. This often happens when they lose a tooth on the opposite side of their mouth, causing an uneven grind when they eat.

Wave Mouth: Yet another form of uneven wear in horses. In some cases, the teeth may wear down to the gum, opening the possibility for a bone infection.

Smooth Mouth: Occurs when the tooth’s denture doesn’t wear as quickly as its enamel. As a result, it creates a smooth surface on the molars, making it more difficult for your horse to break food into smaller pieces. This occurs primarily in younger horses.

To Ensure Healthy Horse Teeth, Make Horse Dental Care a Priority

Don’t be shy to ask your veterinarian questions about your horse’s teeth. Your veterinarian likely has advice on how to best monitor your horse’s teeth and gum health.

As you know, a sore tooth or mouth can be all-consuming and cause you to feel terrible. The same holds true for your horse. Remember the signs and symptoms of dental problems in horses and keep an eye on their teeth.

Having healthy horse teeth is a happy horse! Thank you for taking such great care of your horse.
