Understanding where pressure builds under bridles and bits can help prevent discomfort, tension, and resistance, and improve both welfare and performance.
Poll (top of the head behind the ears)
- Why it matters: This area contains multiple nerve exits and major blood vessels.
- Risks: Narrow or layered crownpieces, overly tight browbands or bridles.
- Signs of discomfort: Head tossing, reluctance to be bridled, stiffness in the poll.
Nasal bones (bridge of the nose)
- Why it matters: The upper part of the nose is made of thin bone, not designed for compression.
- Risks: Over-tight crank, flash, or figure-8 nosebands.
- Signs of discomfort: Head flinging, facial tension, rubbing bridle against objects.
Bars of the mouth (jawline between front and molar teeth)
- Why it matters: This is a narrow strip of bone covered by delicate tissue. It is extremely sensitive.
- Risks: Harsh bit contact, heavy hands, or thin/double bits.
- Signs of discomfort: Gaping mouth, resisting rein contact, dropping behind the bit.
Infraorbital nerve (under the cheekbone)
- Why it matters: Supplies sensation to the upper lip and nose.
- Risks: Tight flash straps, dropped nosebands or cheekpieces pressing too closely.
- Signs of discomfort: Flinching during grooming, head-shy behaviour, facial tension.
Facial crest and zygomatic arch (cheekbones and jawline)
- Why it matters: Key bony landmarks where nerves run superficially, i.e. close to the skin.
- Risks: Buckles or cheekpieces placed too tightly or too close to the bone.
- Signs of discomfort: Bit avoidance, head tilting, inconsistent rein contact.
Chin groove (under the jaw)
- Why it matters: Common site for curb chains and flash straps.
- Risks: Over-tight curb chains or lower nosebands can pinch skin and compress nerves.
- Signs of discomfort: Excessive salivation, head shaking, tongue evasions.
Quick comfort check
Ask yourself:
- Can I fit two fingers under each strap, including flash and crank?
- Is the bridle shaped to avoid key nerve zones or pressing into them?
- Does my horse show behavioural changes once the tack is removed? [end box]
