As equine professionals specialising in tack fitting, we've noticed a significant trend over recent years: more and more horses are displaying clear signs of discomfort related to tongue pressure from their bits. What was once considered "normal" resistance or behavioural issues is now being recognised for what it truly is—physical discomfort that horses are desperately trying to communicate to us.

But this raises some fascinating questions: Are we breeding horses with smaller mouths and less room for traditional bits? Have horses always been uncomfortable with tongue pressure, but we've only just started recognising the signs? Or is it a combination of both factors?

In this article, we'll explore the symptoms of tongue pressure evasion, discuss why this issue seems to be increasing, and most importantly, share the solutions that are genuinely transforming horses' comfort and performance.

What Is Tongue Pressure?

The tongue is an incredibly sensitive organ, packed with nerve endings and essential for a horse's balance, swallowing, and overall comfort. When a bit applies constant or excessive pressure to the tongue, it can cause significant discomfort and lead to a cascade of physical and behavioural issues.

Traditional bits—particularly single-jointed snaffles and many double-jointed designs—create varying degrees of tongue pressure. While some horses tolerate this well, an increasing number are showing us they simply cannot work comfortably with this level of tongue pressure.

Recognising the Symptoms: Is Your Horse Telling You Something?

Horses communicate discomfort in various ways, and tongue pressure evasion can manifest through multiple symptoms. Unfortunately, these signs are often misinterpreted as training issues, disobedience, or simply "the horse's personality."

Common Signs of Tongue Pressure Discomfort:

Behavioural Symptoms:

• Head tossing or shaking - Often during transitions or when contact is established
• Head tilting to one side - An attempt to relieve pressure on one side of the tongue
• Resistance to contact - Refusing to accept the bit or fighting against any rein pressure
• Opening the mouth excessively - Sometimes accompanied by crossing the jaw
• Pulling or leaning heavily on the bit - Counterintuitive as it may seem, some horses lean into discomfort
• Becoming "strong" or unresponsive - Shutting down to pressure they can't escape
• General unhappiness or tension when ridden - A change in attitude once tacked up

Physical Symptoms:

• Tongue hanging out or lolling to the side - A clear attempt to escape pressure
• Putting the tongue over the bit - Perhaps the most obvious sign of tongue discomfort
• Excessive salivation or dry mouth - Both extremes can indicate stress
• Difficulty swallowing - You may notice your horse struggling to swallow during or after work
• Tongue visible between teeth or lips - The tongue protruding in unusual ways
• Bit chewing or playing excessively - Constant movement trying to find relief

Performance Issues:

• Tension through the poll and neck - Tongue discomfort creates tension throughout the entire topline
• Difficulty working correctly through the back - A tense jaw prevents proper biomechanical function
• Inconsistent contact - On and off the bit, never settling
• Resistance to lateral work or bending - Tongue pressure can affect balance and willingness to move laterally
• Loss of rhythm or tempo - Discomfort disrupts natural movement patterns

If your horse displays even one or two of these symptoms, tongue pressure could be the underlying issue. Multiple symptoms together strongly suggest your horse is uncomfortable with the pressure their current bit creates on their tongue.

Why Are We Seeing More Tongue Pressure Issues?

This is the question we find ourselves discussing frequently with vets, physiotherapists, and fellow equine professionals. The increase in tongue pressure sensitivity seems undeniable, but identifying the exact causes requires looking at several factors.

Theory 1: Modern Breeding Practices

Over the past few decades, breeding practices across many disciplines have favoured increasingly refined heads and elegant profiles. While these aesthetics are undeniably beautiful, they may have unintended consequences for bitting.

Considerations include:

• Smaller oral cavities - Less room for the bit and tongue to coexist comfortably
• Lower palates - Creating less vertical space between the tongue and roof of the mouth
• Narrower jaws - Affecting how the bit sits and applies pressure
• Thicker tongues relative to mouth size - Less room for the tongue when a bit is present

Warmblood breeding, in particular, has produced horses with exceptionally refined heads. While this creates stunning horses, it may also mean that traditional bits designed decades or centuries ago simply don't fit the modern horse's mouth as well as they once did.

Theory 2: Increased Awareness and Recognition

Alternatively—or perhaps additionally—it's possible that horses have always experienced discomfort from tongue pressure, but we're only now recognising and acknowledging it.

Why we might be seeing it more clearly now:

• Evolving understanding of equine behaviour - We've learnt that many behaviours previously attributed to "naughtiness" are actually pain responses
• Better education - Riders and professionals are more informed about equine welfare and biomechanics
• Improved diagnostic tools - We can now see and measure things we couldn't before
• Changing attitudes - There's less acceptance of "making the horse accept it" and more focus on genuine comfort
• Social media and information sharing - Riders can connect, share experiences, and learn from each other globally

Think about how many "difficult" behaviours were once considered normal or acceptable: horses who always opened their mouths were simply "mouthy horses"; tongue-over-the-bit was solved with increasingly restrictive nosebands; strong horses needed stronger bits. We now recognise these as potential pain responses rather than training problems.

Theory 3: A Combination of Both

The most likely explanation is that we're experiencing both factors simultaneously. Modern breeding may have created horses with less tolerance for traditional tongue pressure, while our improved awareness allows us to recognise what horses have been trying to tell us all along.

Additionally, consider these contributing factors:

• Earlier starting of young horses - Less physical maturity when introduced to bits
• Dental issues - Better dental care means we're identifying mouth conformation issues earlier
• Higher performance expectations - We're asking more of our horses, making comfort more critical
• Dietary changes - Modern feeding practices may affect oral development

Whatever the cause—or combination of causes—the reality is clear: more horses are showing us they need different solutions when it comes to tongue pressure and bitting.

The Mullen Mouth Misconception

When horses show signs of tongue discomfort, many riders' first instinct is to switch to a mullen mouth (curved, unjointed) bit. The logic seems sound: if jointed bits create tongue pressure through the nutcracker action, a smooth, curved mouthpiece should solve the problem.

And in fairness, mullen mouth bits do significantly reduce tongue pressure compared to jointed alternatives. For some horses, this is indeed the perfect solution.

However, we've observed a concerning pattern with mullen mouth bits that's important to understand.

The Leaning Problem

Many horses who switch to mullen mouth bits begin to lean heavily on the bit. Why does this happen?

The physics behind the leaning:

• A mullen mouth creates constant, even pressure across the entire tongue
• This consistent pressure gives the horse something solid to brace against
• Unlike jointed bits where pressure changes with rein contact, the mullen mouth provides unchanging pressure
• Horses seeking stability or those who previously used tongue evasions may now lean into the bit instead
• The very quality that makes it comfortable (constant, even pressure) can also encourage leaning

This doesn't mean mullen mouth bits are bad—far from it! For many horses, they're excellent. But for others, solving the tongue pressure problem by creating a leaning problem isn't ideal. We're simply trading one issue for another.

What Riders Often Experience:

• Initial improvement in mouth behaviour and acceptance
• Gradual increase in the horse leaning or pulling on contact
• Difficulty achieving lightness or self-carriage
• The feeling that the horse is "heavy in your hands"
• Needing stronger rein aids to achieve responses

So if jointed bits create too much tongue pressure, and mullen mouths can encourage leaning, what's the solution?

Bits That Relieve Tongue Pressure: Real Solutions

Fortunately, bit manufacturers have recognised the tongue pressure issue and developed innovative solutions. Here are the most effective options we've found through years of fitting experience:

1. The Bombers Happy Tongue (Our Top Recommendation)

The Bombers Happy Tongue has become our go-to recommendation for horses showing tongue pressure sensitivity, and for good reason. The results we've seen with this bit have been genuinely transformative.

Design Features:

• Central port (raised section) that creates space for the tongue
• Curved mouthpiece that still maintains contact with the bars and lips
• Available in multiple cheek styles (loose ring, eggbutt, baucher, hanging cheek, etc.)
• Various mouthpiece materials (sweet iron, copper, stainless steel)

Why It Works So Well:

The genius of the Happy Tongue lies in its balance. The port relieves significant tongue pressure—solving the primary comfort issue—while the overall design prevents the leaning problem associated with full mullen mouths.

Here's what happens:

• The port creates genuine relief for the tongue, giving it space to sit comfortably
• The horse can swallow naturally without restriction
• The bars of the mouth still receive contact, maintaining communication
• There's no constant, even pressure to lean against, encouraging self-carriage
• Horses remain responsive and light rather than heavy in the hand

The Results We're Seeing:

The transformations have been remarkable:

Case Study 1: A 7-year-old warmblood mare who constantly put her tongue over the bit, regardless of noseband adjustment. Three different trainers had worked with her, trying various bits and training methods. Within one ride in the Happy Tongue, the tongue issue completely resolved. Six months later, the owner reports the mare is softer, more relaxed, and genuinely seems to enjoy her work now.

Case Study 2: A 12-year-old event horse who had become increasingly strong in the cross-country phase, requiring stronger and stronger bits. The owner was ready to retire him from eventing. We tried the Happy Tongue with a hanging cheek for additional support. The difference was immediate—he remained balanced and responsive without the pulling. He's now back competing successfully in the same bit he schools in.

Case Study 3: A 5-year-old who opened his mouth constantly during flatwork, leading to the use of increasingly tight flash nosebands. In the Happy Tongue, he works with a relaxed jaw and doesn't require any noseband. His overall way of going improved dramatically as tension released through his entire body.

Common feedback from riders:

• "He feels like a different horse!"
• "I finally have a conversation with her mouth instead of an argument"
• "His whole topline has softened"
• "She's actually reaching for the contact now instead of avoiding it"
• "I can't believe the difference—we've tried everything else!"

2. Myler Comfort Snaffle with Wide Barrel

Myler bits are engineered with tongue relief in mind, and their Comfort Snaffle range offers excellent options.

Fitting Matters: Why You Can't Just Buy Online

Here's something crucial that's often overlooked: even the best bit won't work properly if it's not correctly fitted. We see this constantly—riders purchase expensive, well-designed bits online, only to find they don't solve the problem. Often, it's not the bit that's wrong; it's the fitting.

Critical Fitting Considerations:

Width:

• Too narrow: creates pinching and excessive pressure on the lips and tongue edges
• Too wide: slides through the mouth, creating uneven contact and potential rubbing
• Just right: allows approximately 5mm (¼ inch) on each side when positioned correctly

Height in the Mouth:

• Too low: encourages playing with the bit and provides inadequate communication
• Too high: creates wrinkles at the corners and can cause excessive pressure on sensitive tissues
• Optimal: creates one or two wrinkles when first fitted, settling to a gentle contact

Cheek Piece Selection:

• Must complement the mouthpiece and your horse's needs
• Consider mouth shape, discipline requirements, and specific issues
• Different cheek pieces affect how tongue pressure is distributed

Mouthpiece Thickness:

• Thicker mouthpieces distribute pressure over a larger area (generally gentler)
• Thinner mouthpieces provide more precise communication but increased pressure per square inch
• Must be appropriate for your horse's mouth size and sensitivity

Interaction with Bridle Fit:

• The bridle must position the bit correctly
• Browband, noseband, and cheekpiece length all affect bit position
• A well-fitted bit in a poorly fitted bridle still won't work properly

Professional Fitting Assessment Includes:

1. Oral examination - Understanding your horse's specific mouth conformation
2. Current setup evaluation - Assessing what's working and what isn't
3. Observation of symptoms - Seeing how your horse responds to current bitting
4. Measurement and selection - Choosing the right bit(s) to trial
5. Fitting and adjustment - Ensuring optimal position in the mouth
6. Ridden assessment - Evaluating the horse's response under saddle
7. Follow-up support - Checking in as horse and rider adapt

This is why we don't just sell bits—we fit them. The difference between a bit bought online and a professionally fitted bit can be the difference between solving the problem and creating new ones.

Our Philosophy: Happy Mouth, Happy Horse

At The Fitted Horse, we operate on a fundamental belief: when a horse is comfortable in their mouth, they don't need to resist, lean, or evade.

So much of what we interpret as "needing more bit" or "being strong" is actually a horse desperately trying to tell us, "I'm uncomfortable, and I'm trying to escape this pressure!"

The Cascade Effect of Mouth Comfort:

When we solve tongue pressure issues, we see improvements far beyond just the mouth:

Physical Benefits:

• Relaxed jaw - Tension releases through TMJ (temporomandibular joint)
• Soft poll - No longer bracing against discomfort
• Released neck - Freedom to stretch and work correctly
• Engaged back - Proper biomechanical function becomes possible
• Improved movement - Stride length, rhythm, and balance all improve
• Better topline development - Working correctly builds proper muscle

Behavioural Benefits:

• Increased willingness - Horses become more cooperative
• Better focus - Can concentrate on work rather than discomfort
• Reduced tension - Overall anxiety levels decrease
• Improved partnership - Trust rebuilds when pain is addressed
• Enjoyment of work - Horses genuinely seem happier

Performance Benefits:

• Improved responsiveness - Light, willing reactions to aids
• Better balance - No longer compensating for oral discomfort
• Increased suppleness - Ability to work through the body properly
• Consistent contact - Steady, elastic connection
• Enhanced learning - Horses can focus on training rather than pain management

Moving Away from the "Control" Mentality

Traditional bitting philosophy often focused on control: if a horse is strong, use a stronger bit. If they open their mouth, use a tighter noseband. If they put their tongue over, use a different noseband style.

We're advocating for a different approach: address the comfort issue, and the behaviour resolves itself.

This doesn't mean we're against all use of stronger bits or additional tack. Some horses genuinely need more support or communication in specific situations. But those decisions should be made from a foundation of comfort, not in response to pain-based behaviours.

Moving Forward: What To Do If You Suspect Tongue Pressure Issues

If you've recognised your horse in the symptoms described above, here are the steps we recommend:

1. Rule Out Other Causes

Before assuming tongue pressure is the issue, ensure you've addressed:

• Dental problems - Get a thorough dental exam, including checking for wolf teeth, hooks, and sharp points
• Physical pain - Consider saddle fit, back pain, or other physical discomfort that might manifest as mouth issues
• Training gaps - Sometimes behavioural issues are simply training-related rather than pain-based
• Bridle fit - Ensure the overall bridle fits correctly and isn't creating problems

2. Observe and Document

Pay attention to when and how symptoms appear:

• Does it happen in certain situations or throughout all work?
• Has it developed gradually or appeared suddenly?
• Are there patterns related to specific movements or exercises?
• How does your horse behave when the bridle comes off?

3. Consult Professionals

Work with qualified professionals who can assess the complete picture:

• Equine dentist or vet - For oral health assessment
• Qualified bit fitter - For professional fitting and recommendations
• Saddle fitter - To rule out saddle-related issues
• Physiotherapist or bodyworker - To address any compensatory tension patterns
• Qualified trainer - To assess whether training factors are involved

4. Trial Appropriate Solutions

With professional guidance, trial bits that relieve tongue pressure:

• Start with the most appropriate option for your horse's specific issues
• Allow adequate time for assessment (usually 2-4 weeks minimum)
• Ensure proper fitting before judging effectiveness
• Be prepared to try multiple options if needed

5. Monitor Progress

Once you've found a solution:

• Document improvements (or lack thereof)
• Continue working with professionals to optimise results
• Re-assess periodically as your horse develops or changes
• Remain open to adjustments as needed

Conclusion: Listening to What Our Horses Tell Us

The increasing awareness of tongue pressure issues in horses represents a positive shift in equine welfare. Whether we're dealing with changing horse physiology, improved recognition of discomfort, or both, the result is the same: we're finally listening to what our horses have been trying to tell us.

Tongue pressure sensitivity isn't a training problem to overcome—it's a physical discomfort that deserves to be addressed with the same seriousness we'd give any other pain issue.

The solutions exist. Bits like the Bombers Happy Tongue have proven that we can relieve tongue pressure without sacrificing communication or creating new problems like leaning. When professionally fitted and appropriately selected, these bits genuinely transform horses' comfort and performance.
