Under armour performance mouthwear™

Under Armour Performance Mouthwear™ has been engineered to unlock your power and potential.

It’s all in you, but blocked by one of the human body’s instinctive reflex systems – teeth-clenching. With safe, custom-built UA Performance Mouthwear™, athletes in any sport — from football to golf to hockey — can capitalize on innovation that makes you stronger, faster and better.

Whether you need protection in contact sports or you just want to improve your game, Under Armour Performance Mouthwear™, with ArmourBite® Technology, gives every athlete an edge.

Performance Solutions For Every Athlete

The technology is patented. The performance is proven.

The advantages are undeniable. UA Performance Mouthpieces™ deliver a host of physical benefits that help you train harder and compete at a higher level than ever before. UA Performance Mouthguards™ provide those same benefits, with the added benefit of customized dental protection.

Once you have decided which model is right for you, getting your own Under Armour Performance Mouthwear™ is a simple 3-step process. First, your dentist will take your bite impressions. Next, the impressions are shipped to our lab where we custom make the product. Third, the completed mouthwear is shipped back to your dentist for a final fitting.

Jaw-dropping performance

Increases Strength

With improved airflow and less stress from clenching, UA Performance Mouthwear™ has been proven to increase strength by an average of 17% with the UA Performance Mouthpiece™ and 12% with the UA Performance Mouthguard™.

Increases Endurance

UA Performance Mouthwear™ enlarges airway openings, resulting in 25% less lactic acid build-up after 30 minutes of intense exercise.

Speeds Up Reaction Time

Athletes may respond faster when wearing UA Performance Mouthwear™. Clinical trials show an improvement in responding to auditory cues and potential improvement in response to visual cues.

Reduces Athletic Stress

Excess cortisol causes stress, fatigue and distraction. UA Performance Mouthwear™ decreases cortisol production, which means you feel & play better.

Reduces Impact

When the jaw suffers an impact, energy can be transmitted to the head, which can cause concussion. UA Performance Mouthguards™ have been shown to reduce the G-Force impact of blows to the jaw by up to 20%.

Unclench your jaw and unleash a better athlete

You are “hard-wired” to clench your jaw.

When you train and compete, your natural reaction is to clench your jaw. It’s part of the “fight or flight” wiring of your brain. Your clenched jaw and teeth compress your temporomandibular joint (TMJ), triggering the release of excess amounts of performance-sapping hormones (like cortisol) that produce stress, fatigue and distraction.

UA Performance Mouthwear™ helps the human body help itself by unlocking the power of the jaw. Patented ArmourBite® Technology prevents your teeth from clenching and pivots your jaw forward to relieve pressure on the TMJ. Gone are the excess negative hormones and the energy-draining effects, so the body can now unleash its full potential.

Independent studies conducted at some of the nation’s top universities and research centers have proven the undeniable advantages of UA Performance Mouthwear™

How does UA Performance Mouthwear™ differ from mouthguards?

Mouthguards provide protection. UA Performance Mouthwear™, which includes mouthpieces and mouthguards powered by ArmourBite® Technology, does more: It enhances performance. It is not only backed by some of the biggest names in pro sports, it’s also recommended by dentists, pro trainers, strength coaches and wellness experts.

Who should use UA Performance Mouthwear™?

The UA Performance Mouthguard™ offers superior protection in addition to its performance benefits and should be used in contact sports such as football, hockey and lacrosse. The UA Performance Mouthpieces™ are appropriate for non-contact and limited- contact sports such as running, soccer, baseball, golf, tennis and training.

How long does it take to get a custom piece of UA Performance Mouthware™?

Once fitted, the orders typically take 10 days for delivery. Talk to your dentist about shipping options to receive your product sooner.

With over ten years of research, UAPM™ is proven to enhance athletic performance!

Because we reduce cortisol and lactic acid, our research has shown:

  • Increased strength (up to 20%)
  • Increased endurance (avg. 17%)
  • Faster reaction times (up to 49% decrease)

A summary of the technology

  • When under stress or strain like performing in athletics, people tend to clench their teeth
  • Clenching pressure triggers the release of cortisol, a stress hormone that negatively impacts performance
  • UAPM™ reduces the release of cortisol by lessening pressure on the TMJ, so athletes are calmer, more relaxed and more focused. They are also able to react faster
  • Placing UAPM™ in the mouth also opens the airway wider
  • A wider airway aids in oxygen exchange
  • Better oxygen exchange reduces lactic acid. Reduced lactic acid improves endurance

It is all quite pleasant in terms of reception the staff the treatment and the hygienist naturally most of us don’t really like going to the dentist, but as we have to go, this is all pretty good

10th December 2025

I recently had a long-awaited dental implant at Mortiboys, something I’d known I needed for over 20 years, and been to other practices before for a consultation. However, at Mortiboys, it was the first time I truly felt relaxed, informed, and completely cared for. From start to finish, the kindness and professionalism of everyone involved made the experience exceptional. Raj was considerate and professional in his approach, Karlie, his dental nurse, kept me informed and reassured throughout the procedure, and the reception team even followed up afterward to check on how I was doing. I couldn’t have asked for a better experience.I have also had an excellent experience with my Invisalign treatment under Mariola and Charlie, her dental nurse, who have both been consistently supportive, knowledgeable, and encouraging.Overall, every part of my care at Mortiboys has been outstanding.

9th December 2025

Ranya and Clare are the most amazing people. They have been kind and supportive and understanding of my dental anxieties and after almost a year, the results have been remarkable. Ranya completely puts me at ease and I trust her implicitly. Clare is so passionate about her work and has achieved miracles with my gums!
