Horse Dental Welfare: The Hidden Source of Pain and Performance Problems

Dental disease is one of the most common causes of chronic pain and performance problems in horses, yet regular equine dentistry is still far from universal. Good dental care is a fundamental welfare obligation.

Key Facts

Horses' teeth grow continuously and wear unevenly, creating sharp points and hooks that lacerate cheek and tongue tissue
An estimated 50-80% of horses have dental problems that affect their welfare, yet many show no obvious signs
Equine dentistry should be performed by a qualified equine dental technician or veterinarian annually (or more frequently for older horses)
Signs of dental pain include dropping food (quidding), head tossing under saddle, reluctance to bit contact, and weight loss
EOTRH (Equine Odontoclastic Tooth Resorption and Hypercementosis) causes severe incisor pain in older horses
Dental disease is the second most common reason for weight loss in horses after gastric ulcers
Power floating (motorised dental rasping) is faster but requires sedation — when done safely, it reduces stress
Horses with unaddressed dental pain adapt their chewing patterns, reducing digestive efficiency and risking choke and colic

Welfare Considerations

Dental pain in horses is pervasive and persistently underrecognised. Because horses are stoic prey animals that rarely drop out of work due to pain, owners and trainers may attribute performance problems, resistance to the bit, or weight loss to training issues, behavioural problems, or management rather than the dental pain driving them. A horse working daily with sharp enamel points lacerating its cheeks is experiencing chronic pain that affects every aspect of its life — eating, resting, and working. The welfare case for regular equine dentistry is overwhelming: horses with well-maintained teeth eat more efficiently, maintain weight better, show less resistance under saddle, and live more comfortable lives. Annual dental examination is not optional welfare — it is a core component of responsible horse ownership.

What You Can Do

Schedule annual dental examinations with a qualified equine dental technician or veterinarian
Learn to recognise signs of dental pain: quidding (dropping food), head tossing, reluctance at the bit, difficulty eating
Increase dental check frequency for horses over 15 years old, who are at higher risk of EOTRH and other conditions
Ask your vet or EDT to explain findings at each check — knowing your horse's dental history helps ongoing care
Support equine welfare organisations that include dental care in their welfare standards
When purchasing a horse, always include a dental examination in the pre-purchase veterinary assessment
