Summary
# Editorial Summary: Origins of Equine Dentistry Archaeozoological evidence from the Mongolian Steppe reveals that humans were practising intentional equine dentistry as far back as 1150 BCE, making it the earliest documented veterinary dental intervention in any species. Taylor and colleagues examined skeletal remains spanning 3,200 years, identifying anthropogenic modifications to deciduous incisors in Late Bronze Age horses that indicate attempts at extraction, coinciding with the emergence of horseback riding around that period. A significant shift in dental practice occurred approximately 750 BCE with the advent of jointed metal bits: wolf tooth (first premolar) removal became detectable in the archaeological record at this point, suggesting that improved bit technology prompted innovations in oral care to enhance both horse control and animal welfare. These findings demonstrate that nomadic peoples systematically developed dental management techniques to maintain horse health and function in response to changing riding demands, establishing a direct causal link between equipment innovation and veterinary practice evolution. For modern equine practitioners, this work underscores that contemporary dentistry practices—particularly wolf tooth removal and incisor management—have deep historical roots in practical horsemanship and represent proven interventions that have enabled the human–horse partnership to flourish across millennia and continents.

Practical Takeaways
- •Routine removal of retained deciduous teeth and wolf teeth has deep historical precedent and remains justified in modern practice for ridden horses—the practice originated specifically to improve mount performance and safety
- •The timing of dental interventions has always been tied to equipment evolution; changes in bridle technology and riding demands should inform when and how we address equine dental issues
- •Contemporary Mongolian herding practices demonstrate that free-range grazing on gritty forage naturally mitigates many dental problems, suggesting that pasture management and forage type influence the need for dental intervention
Key Findings
- •Earliest evidence of equine dentistry dates to 1150 BCE on the Mongolian Steppe, with anthropogenic modifications to malerupted deciduous central incisors in young horses
- •Removal of problematic deciduous teeth coincided with the adoption of horseback riding in Late Bronze Age Mongolia (ca. 1150 BCE)
- •Wolf tooth (first premolar) extraction first appears in archaeological records around 750 BCE, contemporaneous with the emergence of jointed bronze and iron bits
- •Innovations in equine dentistry practice directly enabled improved horse control and health, facilitating the development of mounted warfare and nomadic empires
