Summary
# Editorial Summary Dental abnormalities—ranging from sharp enamel points and focal overgrowths to more complex conditions such as shear mouth, step mouth, and wave mouth—compromise a horse's ability to process forage effectively, yet the functional impact of correcting these conditions has been poorly documented. Researchers investigated whether dental correction influenced mastication efficiency by measuring fecal fibre length in 30 untreated adult horses with mild to moderate dental disease, collecting faecal samples before and 15 days after dental treatment whilst horses were maintained on a standardised diet of Tifton hay at 1.5% bodyweight daily. Dental correction produced a statistically significant reduction in mean fecal fibre length, from 3.27 ± 2.27 mm to 2.15 ± 1.29 mm (P < .05), indicating substantially improved chewing efficiency and more complete fibre breakdown in the mouth rather than reliance on posterior digestive compensation. Beyond quantifying the measurable benefit of timely dental intervention, this work establishes fecal fibre length analysis as an objective, non-invasive diagnostic tool for assessing dental health status and mastication performance—findings with direct relevance for nutritionists evaluating digestive efficiency, veterinarians monitoring treatment outcomes, and farriers and therapists collaborating on comprehensive musculoskeletal and locomotor assessment.

Practical Takeaways
- •Dental correction improves chewing efficiency, evidenced by reduced fiber particle size in feces—use this objective measure to verify treatment effectiveness
- •Monitoring fecal fiber length provides a non-invasive way to assess whether dental problems are impacting feed processing and digestion
- •Horses with dental abnormalities may benefit from dental treatment to optimize nutrient extraction and digestive efficiency
Key Findings
- •Dental correction resulted in significant reduction in fecal fiber length (FFL) from 3.27 ± 2.27 mm to 2.15 ± 1.29 mm (P < 0.05)
- •Shorter fecal fiber length after dental treatment indicates improved mastication efficiency
- •Fecal fiber length can be used as an objective biomarker to assess dental health in horses
