Biofeedback to address bruxism

Biofeedback has been shown to reduce teeth grinding & clenching (bruxism) in our beta test as well in other studies.

What is biofeedback?

It is a method where a signal (the feedback) is used to alert us when a target biological activity or behavior is detected. For example, teeth grinding or clenching.

This creates awareness that helps stop or reduce the target activity.

Through consistent use, the constant feedback loop eventually creates a persistent reduction in the activity. 

Is biofeedback safe?

Yes. Biofeedback has been used clinically for decades to address or prevent conditions like migraine headaches, chronic pain, incontinence, epilepsy, high blood pressure, and various subconscious habits (nail-biting, hair-pulling, etc.)1

Does biofeedback work for bruxism?

Previous studies have shown that biofeedback reduces the duration and frequency of sleep bruxism episodes without affecting sleep quality.2-7 In our initial usability test, we saw an average 49% reduction in grinding duration during sleep while maintaining sleep quality. For awake bruxism, similar results have been reported. One study from Brazil reported that the use of biofeedback significant reduced pain symptoms & migraine in a group of awake bruxers.10

No. Most teeth grinding episodes occur during light sleep (microarousal phase in Stage 1/2 Non-REM sleep)8. This means you are already in a state of brief awakening and less likely to be jarred awake, since you are not in a deep sleep. Previous studies showed that sleep duration, sleep quality, and sleep architecture weren’t affected by the stimuli during biofeedback2-7 so we expect similar result from Jawsaver. In our usability test, user reports similar sleep quality before and after using Jawsaver.

As soon as you use it, the biofeedback will immediately help stop reduce the duration of your teeth grinding and clenching episodes.

We are actively studying the hypothesis that consistent use of Jawsaver over time will result in reduction in bruxism episodes overall, similar to results that have been observed with other biofeedback devices.

It’s unlikely as we still don’t know what causes bruxism. In addition, some level of teeth grinding is actually considered normal9.

What this biofeedback device does is to reduce your bruxism behavior to a level where it does not cause jaw or dental problems.

Please note that Jawsaver is not a medical device. It is not intended to diagnose, treat or cure any medical conditions. The purpose of the device is to help bring more awareness when you are grinding or clenching your teeth.

No. The device is silent and the vibration is very slight and short. Most likely your partner and others around you won’t even notice it.
