Horse Dentistry and Welfare: Beyond the Annual Float

Why equine dental care goes beyond annual floating and how dental problems cause significant welfare harm that is frequently underestimated.

Key Facts

Horse teeth erupt continuously at approximately 3mm per year throughout life - dental work manages this eruption pattern
Sharp enamel points on molar arcades cause cheek and tongue lacerations during chewing - the most common dental welfare problem
EOTRH (equine odontoclastic tooth resorption and hypercementosis) causes extreme chronic dental pain in horses over 15 years
Horses with dental pain often show reduced weight, quidding (dropping partially chewed food), head tilting and bit resistance
Dental work requires sedation in most adult horses for safe examination and adequate treatment to all arcades
Many horses do not show obvious signs of dental pain despite significant pathology - regular examination is the only reliable way to detect problems

Welfare Considerations

Equine dental welfare suffers from the same underdetection problem as dental welfare in many companion animals - horses continue eating despite significant dental pain because the drive to eat is stronger than most pain inhibition thresholds. A horse with significant molar arcade issues that causes ongoing lacerations, reduced forage processing and swallowing discomfort may show no behaviour change that owners recognise as dental. The chronic welfare cost accumulates silently over months. Regular dental examination under sedation by a qualified equine dentist - at least annually for young horses, twice yearly for horses over 15 - is the only reliable way to detect and address dental problems before they become severe welfare concerns.

What You Can Do

Schedule annual dental examinations under sedation for horses under 15 and twice-yearly for horses over 15
Ensure dental examination includes full mouth opening and speculum use to visualise all arcades - manual examination without speculum is inadequate
Choose a qualified equine dental technician with appropriate veterinary supervision or a veterinary dentist for dental work
Monitor for signs of dental discomfort including weight loss, quidding, head tilting and feed preference for softer forage
Address EOTRH promptly in older horses - extraction of affected incisors is painful but provides substantial welfare relief
Maintain accurate dental records including photographs of arcade abnormalities to monitor progression over time
