Horse Dentistry and Welfare: The Hidden Impact of Dental Pain

Dental disease is one of the most common and frequently unrecognised sources of chronic pain in horses, with consequences for eating, behaviour, ridden performance, and overall wellbeing that make regular dental care a welfare essential.

Key Facts

Horses have hypsodont teeth that erupt continuously throughout their lives, creating uneven wear, sharp points, and hooks that cause mouth pain
An estimated 80-90% of horses have dental problems requiring treatment, but many receive infrequent or no dental care
Sharp enamel points on the cheek teeth cause lacerations to the tongue and cheek lining during eating and bitting
Horses with dental pain often show performance problems including head-tossing, resistance to the bit, and reluctance to accept contact — frequently misdiagnosed as behavioural issues
Wolf teeth, retained caps, and displaced teeth are common developmental issues requiring intervention in young horses
Equine dental specialists (EDTs) and veterinary dental surgeons recommend annual dental examinations for horses over 2 years old
Weight loss, dropping food (quidding), and reluctance to eat hard feeds are classic signs of significant dental pain in horses

Welfare Considerations

Dental pain in horses is a pervasive and underappreciated welfare problem because horses instinctively continue eating despite significant oral pain — their survival depends on maintaining forage intake. This means that even horses with severe dental disease continue to eat, and owners may not recognise the problem until secondary signs such as weight loss or performance issues become obvious. The welfare impact of untreated dental pain is continuous and affects eating, social behaviour, and ridden work simultaneously. Annual dental examination and treatment is one of the most straightforward and high-impact welfare interventions available to horse owners.

What You Can Do

Book an annual dental examination for every horse in your care, including ponies and older horses
Learn to recognise signs of dental pain including quidding, weight loss, head-tossing, and asymmetric jaw movement
Use a qualified equine dental technician or veterinary dental surgeon — not an unqualified person for dental treatment
Never assume that resistance under saddle is purely behavioural — always rule out dental pain first
Ensure young horses have their first dental examination at 2 years old when wolf teeth and caps are most likely to need attention
Ask your vet to include a basic oral examination at every annual health check
Provide appropriate hard feed for horses with dental limitations — soaked feeds or grass nuts for horses with poor tooth function
