Dental problems in horses

In centuries past, looking into a horse's mouth played an important role, albeit primarily to determine the animal's age. Today, the focus is more on dental care and dental disease in horses. Dental hygiene is a very important aspect of keeping horses healthy. Regular veterinary checks of the mouth and teeth should be carried out at least once a year. The annual check-up and routine dental treatment can be carried out by any equine practice. In the event of specific dental problems or complications, it is advisable to consult a practice that specializes in equine dentistry. Typical dental problems in horses include tartar and the formation of hooks and edges on the molars due to uneven wear. These issues can be quickly resolved during routine treatment, preventing further damage. But how can we, as horse owners, tell if our horse has dental problems?

Recognizing dental problems

It is not easy to link symptoms to actual dental problems. This is because in horses, clear signs are usually only noticeable when the disease is already advanced. As a horse owner, you can use the following indicators to recognize that your horse may be suffering from a dental problem:

  • Loss of appetite and reduced feed intake
  • Bad breath and/or salivation
  • Hardly any undigested feed fibers in the manure
  • Chewing on small bundles of hay that have formed due to insufficient or no chewing and fall out of the horse's mouth
  • Diarrhea
  • Unusual chewing movements
  • Weight loss with no change in feed intake

Symptoms of toothache in riding horses

Riders should be alert if their horse shows resistance to the bit or bridle. Head shaking or head shying behavior can also be possible indications of pain in the mouth or teeth. Problems in the jaw joint can manifest themselves in horses in the form of teeth grinding. Physical blockages or poorly fitting bridles that can exert pressure on the jaw may be responsible for this. However, some horses also react to excessive demands or stress by grinding their teeth. If the horse only grinds its teeth under certain circumstances when riding, the riding style and the fit of the saddle should be checked. These symptoms described for riding horses must be considered from a broader perspective, as resistance in horses can also be caused by many other problems.

Teething and wolf teeth

We observe temporary toothache caused by teething in young horses up to around the age of seven. When milk teeth are replaced by permanent teeth, cysts sometimes form in the jaw, also known as bumps or knobs. These are usually visible on the outside as a painless, firm swelling that disappears again on its own within a short time.

If present, so-called wolf teeth can also cause problems. These are not fully developed teeth, but remnants from the development of the horse's dentition. Wolf teeth do not occur in every horse, nor do they always occur in the same type and number. They are located at varying distances in front of the first molar and usually have very short roots. When riding, wolf teeth can cause pain to the horse through contact and pressure from the bit. Chewing problems can also occur. It is advisable to have these teeth removed by a veterinarian. This requires a minor surgical procedure, which can be performed in the stable under light anesthesia.

Tooth infections

Inflammation in the horse's mouth can have various causes, but it occurs more frequently in older horses and often results from injuries caused by sharp tooth tips or tooth fractures. A tooth infection can spread from the tooth root or gums. Various symptoms occur, such as refusal to eat, bad breath, local swelling, or even fever. If the infection is already advanced and has also affected the nasal or maxillary sinuses, this can manifest itself in unilateral nasal discharge and should be treated urgently by a veterinarian. Under certain circumstances, the infected teeth may then have to be extracted under sedation or general anesthesia.

So don't be afraid to take a look in the mouth of a "gift horse," because it's not just about age, but above all about the health of your pet.

Dental prophylaxis

Have a routine dental check-up carried out by a vet every year. If there are already known dental problems, this may be advisable every six months. After major dental work, a check-up appointment is recommended after eight weeks.
