And this is why it's worth investing in dental care provided by practitioners that understand and are able to provide biomechanical function and balance.

🧠🦷 Mechanoreceptors, Cranial Nerves & the TMJ: How Oral Health Shapes Whole-Horse Biomechanics

When it comes to equine movement, we often start at the feet — but science tells us to start at the skull.

Why? Because inside the temporomandibular joint (TMJ), cheek teeth, incisors, and periodontal ligament, there are thousands of mechanoreceptors—specialized nerve endings that detect:
👉 Pressure
👉 Tooth contact
👉 Tension
👉 Jaw movement

These sensory signals don’t just go to one nerve — they’re processed by a complex network of cranial nerves, especially:
🔹 CN V (Trigeminal) – Facial sensation, mastication
🔹 CN VII (Facial) – Expression, tension around the lips and jaw
🔹 CN IX (Glossopharyngeal) – Swallowing, oral sensitivity
🔹 CN X (Vagus) – Autonomic regulation, gut-brain connection
🔹 CN XI (Accessory) – Neck and shoulder motor control
🔹 CN XII (Hypoglossal) – Tongue movement and posture

📡 These cranial nerves form the neurological bridge between oral function and full-body coordination. They regulate:
✅ Jaw and tongue control
✅ Head–neck–shoulder movement
✅ Postural reflexes
✅ Proprioception and balance
✅ Autonomic nervous system responses

🔍 But when there’s dental malocclusion (uneven incisors, overgrown cheek teeth) or periodontal disease (inflammation of the tissues anchoring the teeth), those mechanoreceptors send altered signals to the brain. This sensory distortion can lead to:
⚠️ TMJ tension and bracing
⚠️ Head tilting, poll tightness
⚠️ Asymmetrical movement
⚠️ Inconsistent rhythm or contact
⚠️ Digestive or behavioral changes

💡 The cranial nerve system doesn’t just control the face — it influences the entire postural and emotional state of the horse.

✨ When we restore oral balance, reduce periodontal inflammation, and support the clarity of cranial nerve signaling, we’re not just helping the mouth — we’re unlocking the horse’s full-body biomechanics.

This is where true transformation happens: through a multidisciplinary approach that connects dentistry, neurology, posture, and movement into one whole-horse picture. 💡🧠🐴

New Research Highlights Possible Link Between Dental Disease and Gastric Ulcers in Horses

Poor dental health may impact more than just a horse’s ability to chew—it could influence their entire digestive health. Researchers recently explored a possible connection between dental disease and equine gastric ulcer syndrome (EGUS), a common and painful condition in horses.

The hypothesis? Dental issues reduce chewing efficiency, decreasing saliva production. Since saliva helps buffer stomach acid, less chewing may lead to more acidic gastric juices—contributing to ulcer formation. Horses with dental pain may also avoid long-stem forage, eliminating the protective “mat” that normally shields the stomach lining from acid splash.

In a study of 54 horses showing signs of gastric discomfort (e.g., weight loss, poor appetite, colic, girthiness), gastroscopy revealed:
• 56% had moderate-to-severe squamous ulcers
• 17% had significant glandular ulcers
• 13% had both types of ulcers
• 48% had moderate-to-severe dental abnormalities

While a direct link wasn’t confirmed, researchers emphasize that oral and gastric exams should be standard in horses with chronic digestive symptoms.

“Daily digestive buffers and regular dental care are key tools in supporting gastric health—especially in horses with dental challenges or those fed primarily processed forages,” said Catherine Whitehouse, M.S., of Kentucky Equine Research.

Takeaway: Routine dental exams are more than just maintenance—they may be essential for preventing digestive disorders that impact equine health, behavior, and performance.

Feeling lucky to be in a position to take this beautiful photo of my place of work today. I'm in Kaikoura after rounding a bend just north of Amberley to face an arctic truck heading straight at me, in my lane whilst over taking a tractor between two bends where there was definitely not enough room to do so!
