Sleep & Jaw Health
Is jaw tension ruining your sleep?
You wake up exhausted. Your jaw aches. Your partner says you grind. But you've never been able to see what's actually happening at night — until now. JawSense measures your nights, and gives you something to do about them.

Signs bruxism may be affecting your sleep
Bruxism — grinding or clenching your teeth — is one of the most common things that disrupts sleep, and one of the least noticed. Here's how it might be showing up for you.
Morning jaw pain or stiffness
Waking up with a sore jaw, facial pain, or difficulty opening your mouth is one of the most common signs of sleep bruxism.
Frequent headaches upon waking
Tension headaches, especially in the temples, are strongly associated with nocturnal clenching and grinding.
Partner reports grinding sounds
Audible teeth grinding during sleep is a telltale sign — but many people grind silently (clenching), which is harder to detect.
Unrefreshing sleep despite enough hours
Bruxism can fragment sleep microstructure. You may get 7-8 hours but still feel exhausted because your jaw muscles are active all night.
Worn, cracked, or sensitive teeth
Your dentist may have noticed flattened tooth surfaces, chips, or increased sensitivity — all signs of chronic grinding.
Ear pain or ringing (tinnitus)
The jaw joint sits right next to the ear canal. TMJ tension from bruxism can cause ear pain, fullness, or ringing.
The Science
How bruxism disrupts your sleep
Published research shows that bruxism doesn't just damage teeth — it directly impacts sleep quality through multiple mechanisms.
Sleep Fragmentation
Bruxism episodes are associated with micro-arousals — brief awakenings that fragment your sleep architecture without you being consciously aware.
Muscle Tension Cycle
Sustained jaw muscle activity during sleep prevents the deep relaxation your body needs. This creates a tension-fatigue cycle that compounds night after night.
Stress and sleep, in a loop
Stress can make grinding worse, and broken sleep from grinding makes stress harder to handle — a loop that feeds itself.
Step by step
How JawSense helps improve your sleep
01
Start your symptom diary
Start free in the app. Log your morning jaw pain, headaches, and sleep quality. Within days, you'll see patterns you never noticed.
02
Learn to notice
Daytime check-ins teach you to catch the clench while it's happening. Whether practising by day also quietens the night is an open question — one small study of daytime biofeedback (Sato 2015, seven people) saw fewer night episodes too. Sadly nobody has studied this for check-ins alone (as far as we know!).
03
See what happens at night
Add JawSense ONE for objective nighttime monitoring. See your actual jaw activity, sleep quality, and how both change over time.
04
Keep it up
Keep the check-ins and the guided relaxation going, and watch your own numbers week by week — the nights tell you whether it's working.

Slept through the cues
I was worried I'd notice the cues at night. I didn't — I slept through, and the report in the morning was the surprise.
First hope in years
I've been dealing with night-time teeth clenching since I was a teenager — I'm now 40. I've tried everything including Botox. JawSense is the first bit of hope I've had in ages.
Saw how much it happens
It's so interesting to see how much I'm actually clenching and grinding my teeth. I finally understand why I feel so bad in the morning.
