How the Functional Activator Trains Perfect Tongue Posture

Unlike traditional mouthguards that only protect teeth, our patented tongue posture trainer addresses the foundation of facial development:

  • The Problem with Regular Night Guards
  • Only protect teeth from grinding
  • Don't train tongue positioning
  • No mewing support or facial development benefits
  • Miss the root cause of breathing issues

Why Our Tongue Posture Training Device Works Better

The Functional Activator trains your tongue to rest against the roof of your mouth, which:

  1. Supports mewing results - Accelerates facial development through proper tongue positioning
  2. Improves breathing patterns - Natural nasal breathing through correct tongue posture
  3. Enhances jawline definition - Consistent tongue training strengthens facial structure
  4. Develops muscle memory - Long-term tongue posture improvement for lasting benefits
  • Place the Functional Activator in your mouth to guide your tongue to the correct position.
  • Start with 15-minute sessions, a few times a day, to build the habit of nasal breathing and proper tongue posture.
  • Gradually work up to wearing it at night for the best results.
  • Over 10-12 months, neuroplasticity will naturally help your tongue rest in the correct spot.
  • Enjoy a permanent improvement in tongue posture and breathing.

The Only Mouthguard That Addresses Tongue Posture

Poor tongue posture is the hidden cause of mouth breathing, jaw clenching, and forward head position. Regular night guards ignore it completely. The Functional Activator trains your tongue to rest at the roof of your mouth while you sleep. This opens your airway, relaxes your jaw, and lets your body actually recover overnight.

You can't consciously maintain proper tongue posture 24/7. This does it automatically while you sleep. Zero effort during the day. Maximum correction at night.

Frequently Asked Questions

Measure from molar to molar using dental floss. Place the floss against a ruler.

  • Under 26mm = Small
  • 26-28mm = Medium
  • Over 28mm = Large

The Functional Activator reveals imbalances in your bite that were already there. If your jaw closes unevenly—say, your back molar on one side touches before the other—that asymmetry gets amplified during sleep. You're not creating a problem. You're feeling one that was hidden.

This is actually useful information. It tells you where your jaw is compensating. Most people find the soreness decreases within 1-2 weeks as the tongue repositions and jaw tension releases.

If soreness persists in one specific spot: You may have a significant bite asymmetry worth addressing with a practitioner.

Your mouth has adapted to incorrect tongue posture—possibly for decades. The Functional Activator puts your tongue where it should be, which can feel unfamiliar.

Start with 5 minutes during the day. Increase gradually. Most people adapt within 1-2 weeks.

Trim if needed: Use scissors to remove 1mm from any edge pressing into your gums. Keep the wave shape intact.

It's designed that way. The Functional Activator is wider than your jaw on purpose—it's made from flexible material that adapts to your mouth.

How to insert:

  • Squeeze the sides together with your thumb and index finger
  • Place your upper and lower teeth into the gutters while still squeezing
  • Bite down gently to find your position
  • Release your fingers—the activator expands to fit your jaw width

It should feel snug, not forced. The width self-adjusts once you release.

Start with 5 minutes during the day. Your mouth has adapted to incorrect tongue posture—possibly for decades. The correct position feels unfamiliar at first.

If the edges press into your gums: Trim 1mm at a time with scissors. Keep the wave shape intact.

Most people adapt within 1-2 weeks.

functional activator

génial, depuis que je porte cette gouttière je ressens un mieux être physique. J'ai l'impression d'avoir une posture plus saine. Je la mets principalement pour dormir. Mon sommeil est plus sain aussi. Plus réparateur. Mes performances sportives sont également meilleures.

Nose breathing

To place this peace of help in the mouth is a joy for your breathing pattern. In rest or activities, training your breath and position of the tongue and jaw. Love the proces.

Amazing

This is exactly what I was looking for! No more mouth taping needed. Completely breathing threw my noise, and feeling restored when I wake up. My front did hurt for the first few times but was able to get used to it and now doesn't hurt at all.
