YOUR POSTURE STARTS IN YOUR MOUTH.

The Functional Activator is the only active device that trains your mouth, jaw, tongue, and facial muscles while you wear it.

Tongue PostureNasal BreathingJaw and Neck Tension

Most mouthguards protect teeth.

This trains the muscles behind the jaw.

Tongue posture, breathing, jaw position, and whole body alignment all begin with where the tongue rests.

WHY THE FUNCTIONAL ACTIVATOR IS DIFFERENT

Not all mouthguards are created equal.

It is a daytime mewing alternative that trains the tongue, jaw, breathing, and posture.

See how the Functional Activator works

The Functional Activator trains the tongue to find its proper resting position, helping support jaw alignment, nasal breathing, and whole body balance.

FUNCTIONAL ACTIVATOR

  1. START WITH SHORT DAYTIME WEAR

    Begin by wearing the Functional Activator for a few minutes at a time while watching TV, working, walking, or training.

  2. SQUEEZE AND PLACE IT IN YOUR MOUTH

    Gently squeeze the device, place it in your mouth, and allow it to fit naturally between your teeth.

  3. CLOSE YOUR TEETH AROUND IT

    Make sure both upper and lower teeth are in contact with the device. The Functional Activator is active, which means your mouth, jaw, tongue, and facial muscles have to engage with it.

  4. KEEP YOUR LIPS CLOSED

    Once the device is in place, close your mouth and keep your lips sealed. If this feels difficult at first, it may indicate weakness in the muscles around the mouth, especially the buccinator, which is often involved in mouth breathing patterns.

  5. BUILD TOLERANCE GRADUALLY

    Use it for short sessions throughout the day and increase gradually. A good goal is to wear it in 15 minute intervals as your mouth and facial muscles adapt.

  6. BUILD UP YOUR DAILY WEAR TIME

    The final goal is comfortable, longer daytime wear, so the tongue, jaw, lips, and breathing pattern get consistent training through the day.

Functional Activator

The first few sessions may feel unusual. That is normal. Start slowly, keep the lips closed, and allow the mouth, tongue, jaw, and cheek muscles to adapt over time.

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 to 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 to 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 to 2 weeks.
