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 33mm = Small
  • 34-37mm = Medium
  • Over 38mm = 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.
