CLINICALLY PROVEN RESULTS

In this clinical trial, athletes using New Age Performance technology saw an average increase of 53% in rep volume compared to training without it. By stabilizing the jaw and neck musculature, the mouthpiece delays the onset of central nervous system fatigue, allowing you to push past previous plateaus instantly.

SUPERIOR JAW
ALIGNMENT

Proper jaw alignment effectively lowers cortisol levels, increases oxygen intake, and eliminates the power-sapping effects of tooth clenching. Whether you are using our 5DS or 6DS technology, you will have a stabilized foundation.

OPTIMIZED
AIRWAY FLOW

Our patented mouthpiece design keeps your tongue and jaw in the perfect position to maximize oxygen intake. Breathe easier whether you’re in the midst of a grueling gym session, sleeping soundly in your bed, or working diligently at your desk.

In my practice as a neuromuscular dentist, I’ve observed that the foundation of physical performance often begins with the jaw. By utilizing a device that establishes optimal vertical spacing and mandibular positioning, we can effectively 'level' the head and neck. This structural alignment ripples down the kinetic chain, alleviating muscular strain in the shoulders and back while improving overall postural stability. This technology successfully bridges the gap between clinical neuromuscular principles and daily athletic recovery, allowing the body to function with significantly higher mechanical efficiency.

Making a Difference

Just got this and tried it for a few nights. It’s great! I grind my teeth and often wake up with a sore jaw. This fixed that and I feel much better in the mornings. I’ll continue using this and will update my review if I feel like anything changes.

Best Guard Ever

I’m really impressed. I noticed a big difference in how relaxed my jaw felt, and I woke up without the usual tension or discomfort. I feel so much more rested in the morning because I’m sleeping better at night. I would highly recommend this to anyone!

No More Neck Injuries

Really blown away by the difference this makes. Biggest issue I had was moving my jaw while doing heavy log presses. It would cause me to move my head and strain my neck, putting me back further from my goals. Since getting this mouthpiece, I haven't had a single strain or neck injury.

Wish I Bought Sooner

I had a filling for a little part of my tooth and would grind my teeth while lifting heavy. I usually would break my fixed part of tooth off and have to get it fixed. This keeps a good little gap between teeth when clenching teeth together while lifting heavy and haven't messed up my fixed tooth again.

Frequently asked questions

Traditional mouthguards are designed primarily for impact protection. New Age Performance mouthpieces are biomechanical tools. Both our 5DS and 6DS models utilize patented technology to provide vertical separation and mandibular advancement. This aligns your jaw into its most powerful physiological position, which helps balance the muscles in your head and neck, increases oxygen intake, and prevents power-sapping clenching.

For the average athlete training 3–5 times per week, a mouthpiece typically lasts about 3 months. Because our technology relies on precise dimensional alignment, the material will naturally compress over time due to the high-pressure forces of clenching during training. To maintain peak performance benefits, we recommend replacing it once the material shows significant wear.

For heavy, static lifts like squats, deadlifts, and bench presses, the 6DS Heavy Duty is ideal. These models provide 6 dimensions of jaw stabilization, which is specifically engineered to handle the intense clenching and high-load forces associated with maximal strength training.

The 5DS Wellness Mouthpiece is the preferred choice for those looking to alleviate the discomfort of clenching. It focuses on the core principles of vertical separation to relax the masseter muscles and reduce tension in the jaw, neck, and shoulders, making it perfect for daily wear or light activity.

The 5DS Performance is our most versatile option. It provides 5 dimensions of stabilization, making it perfect for athletes who move between lifting, agility drills, and cardio. It offers the perfect balance of airway opening and jaw stability for general fitness and multi-sport training.

We recommend the 6DS Low Profile. This is designed with a sleek fit that maximizes oxygen flow. The 6DS Low Profile is particularly effective for HIIT athletes who still engage in heavy power movements but require a less bulky feel for easier breathing and communication.

Our mouthpieces use a simple "Boil and Bite" process, but with a critical difference: you must ensure your jaw is slightly advanced forward during the biting phase. Each mouthpiece comes with a fitting tool or specific instructions to help you achieve the correct mandibular advancement, which is the key to unlocking the neuromuscular benefits.
