Fitting the boil & bite iMG in under a minute

The best safety technology is the technology that actually gets worn. That's why the Prevent Impact Monitor Mouthguard comes in a hybrid boil & bite form - a standard, off-the-shelf guard that takes about a minute to personalize for any athlete, with no dental appointment required.

Here's the whole process, start to finish.

Three steps, about sixty seconds

1. Heat. Bring water to a boil, then let it sit briefly off the heat. Submerge the iMG for the time stated in the quick-start guide. The thermoformable liner softens; the electronics are sealed and unaffected.

2. Seat. Place the guard onto the upper teeth and bite down firmly. Press the cheeks and lips inward and use the tongue to push the liner up against the roof of the mouth so it hugs the teeth and gumline.

3. Set. Transfer to cold water to lock the shape. Check retention - a correctly fitted iMG stays put when you tug gently. If it isn't right, simply reheat and refit; the liner is forgiving.

Why the fit is the data

Retention isn't just about comfort. The sensor only measures head kinematics accurately when the guard is coupled tightly to the upper dentition. A loose fit introduces movement that has nothing to do with a real impact. A good fit is what makes "On teeth" a meaningful status - and what keeps the measurements trustworthy.

Boil & bite vs. custom

For squads that need to kit out a full roster quickly, boil & bite is the fast path: one minute per athlete, repeatable, and replaceable. For elite athletes who want the most refined fit, the custom iMG is built from a dental scan of the upper teeth. Both feed the same platform and the same five measurements - the difference is purely how the guard is shaped to the mouth.

Comfortable enough to forget, snug enough to trust. That's the bar a wearable head-safety device has to clear - and it starts with a good fit.
