TMJ pain is real. So is the science that helps.

TMJ pain is real, and it usually tracks load — hours of quiet clenching the joint never signed up for. The useful first step is seeing when that load happens.

The Problem

Why most TMD approaches don't work

You've been told it's stress. You've been given a night guard. Maybe you've been dismissed entirely. Here's what most approaches miss: a large share of people with TMD also grind or clench — behaviour that keeps reloading a sore jaw. Managing TMD without understanding your bruxism is managing half the problem.

JawSense helps you see the full picture: exercises for the sore jaw, and a way to catch the grinding and clenching that keep it sore.

Why it happens

The jaw is where you feel it. It isn't where it starts.

Your jaw doesn't decide to do this. Your nervous system does — mostly without asking you first. It isn't your bite. It isn't weak willpower. And it's never one thing.

Stress & emotionThe best-established piece — for daytime clenching. At night it colours the picture rather than flipping the switch.
Sleep & breathingMost of the night's activity clusters in lighter sleep, around the moments your brain briefly surfaces.
Daytime loadEight hours of quiet bracing at a desk doesn't politely clock off at bedtime.
What you drink & takeAlcohol, caffeine, nicotine and some medications are all associated with more jaw activity.
GeneticsSome of this simply runs in families. It isn't something you did.
Posture & habitsWhere your head, neck and tongue sit changes what the jaw is quietly asked to hold.

Single-cause fixes keep disappointing people for the same reason. Fix the bite, manage the stress, buy the guard — each aims at one input and hopes it was the one. We'd rather measure the thing they all end up in.

How JawSense helps with TMJ pain

Measure it first, then change it. Nothing here starts from a guess.

01 · See it
Jaw Activity Assessment
Measure how often and how hard your jaw works at night — the load picture your daytime symptoms never show you. The app's daytime check-ins run alongside — they map the half you're awake for, and the sensor takes that half over directly once the Day Biofeedback Programme ships.
- Two nights in your own bed
- Your Jaw Score and your Jaw Activity Report, yours to keep
- The Results Walkthrough — a 15-minute call to go through your results
Read about the Assessment
02 · Change it · nights
The Night Biofeedback Programme
Then work on reducing night-time clenching and grinding — twelve measured weeks aimed at the behaviour, not the label. Release work in the app runs alongside, free — guided exercises, and tracking for whether either half is shifting.
- Starts from your own Assessment, never from a guess
- Twelve weeks of biofeedback tuned to your own jaw, in small groups
- A cue the moment your jaw goes to work — so the habit gets interrupted, not just recorded
Read about the Programme
03 · Alongside · days
The daytime half, in the app
The nights are one half. The other happens while you are awake, and it does not wait for a device — check-ins that catch a clenched jaw while you can still feel it, release work you can do at a desk, and a record of whether either half is shifting.
- Daytime check-ins, at varied moments so they keep catching you
- Guided release and jaw-relaxation exercises
- Yours whether or not you ever measure a night

Why JawSense

Why load is the thing to measure

Our exercise library is built from the jaw-exercise protocols an international expert panel agreed on (Lindfors et al., 2019). We didn't run that study; we follow it.

Mind, body and habits — all three, not just one

Techniques from published randomised trials

In your own hands, when it suits you — no appointments

Built by people who grind their teeth — with clinical input

Frequently Asked Questions

Is TMJ pain something I just have to live with?

No. Conservative self-management — exercise, education and habit change — is what most people are offered before anything irreversible is considered. How much it helps varies by person and by what your jaw is actually doing, which is the argument for measuring rather than guessing.

Do I need surgery for TMJ?

Almost certainly not. Surgery is a last resort, after everything else has been tried. Most people never get there. JawSense is what you try first: exercises, a symptom diary, and learning to catch the clench.

Why does my pain keep coming back?

Often because something is keeping the pain going and nobody has spotted it. Bruxism is a big one — a large share of people with TMD grind or clench. If you do your exercises by day but grind all night, you won't get far. JawSense helps with both: self-management now, and the two-night Assessment when you want to see what your nights are actually doing.

Is this just another 'learn to relax' solution?

No. 'Just relax' helps nobody. JawSense gives you exercises from clinical protocols, an explanation of how pain works, training to change the habit, and a symptom diary — all from published research. A full programme, not a platitude.

Is the app free?

The free part stays free: check-ins through the day, a symptom diary, the first exercises, and the basics of what your jaw does. No card, no trial that runs out. Premium adds the full exercise and education libraries and your statistics — a subscription that supports our small team's research.
