Horse Dental Welfare: Recognising and Treating Mouth Pain

Dental disease is among the most common but underrecognised sources of pain in horses. Annual dental examination by a qualified equine dentist is one of the most impactful welfare interventions available.

Key Facts

Horses have hypsodont (high-crowned) teeth that erupt continuously throughout life; uneven wear creates sharp edges.
Sharp enamel edges on cheek teeth cause lacerations to tongue and cheek mucosa during chewing.
Horses with dental pain may show resistance to the bit, head-tossing, dropping feed, and weight loss.
Annual examination under sedation by a qualified equine dental veterinarian or technician is current best practice.
Dental floating (rasping sharp edges smooth) is a significant welfare intervention for horses with irregular wear.
Equine dental problems are more common in older horses but occur at all ages.
Bit problems and training difficulties attributed to behaviour are often caused by unrecognised dental pain.

Welfare Considerations

Equine dental welfare is underserved relative to companion animal dentistry, partly because horses do not naturally show dental pain through obvious signs and partly because examination without sedation provides limited information about the mouth's condition. The consequences of untreated dental disease are significant: chronic mouth pain affects behaviour and training, reduces food intake and body condition, and causes localized tissue damage from sharp edges. The welfare case for annual dental examination is straightforward: the procedure identifies and corrects problems before they become severe, the intervention (floating) is simple and immediately welfare-positive, and the cost is modest relative to the benefit. Framing equine dentistry as a welfare priority — rather than an optional extra — changes the likelihood of owners investing in it.

What You Can Do

Schedule annual equine dental examination by a qualified equine dental veterinarian or technician.
Never assume resistance to bit or training difficulties are behavioural without ruling out dental pain.
Ensure older horses receive examination every 6 months due to increased risk of problematic wear patterns.
Observe horses eating for signs of dropping feed, one-sided chewing, or discomfort that may indicate dental pain.
Advocate for equine dental care to be included as a standard component of annual welfare checks.
