GLOBAL - Setting up GrindCare in the evening

This video shows how to make GrindCare ready for use in the evening. The video includes how to make the electrode ready, how to set the stimulation level and how to calibrate GrindCare before use.

1. Getting started

GrindCare is a medical device for people who suffer from nighttime tooth grinding or clenching, a condition known as sleep bruxism. During use, GrindCare detects and measures bruxism episodes and emits mild electrical impulses, known as Contingent Electrical Stimulation (CES), in response. These mild impulses instruct the jaw muscles to relax, leading to a reduction of grinding or clenching without disturbing sleep.


2. Before going to sleep



  1. Check that the Sensor is sufficiently charged for the night’s treatment – see section 'Getting started' on how to check charging level. Ensure that the skin of your temple is clean, dry and free from creams or makeup.
  2. Take a new GelPad. Remove the smaller plastic film with the yellow sticker. Make sure the larger plastic film on the other side remains attached. Note: Use a new GelPad every night – otherwise functionality (adhesiveness and electrical conductivity) cannot be guaranteed.
  3. With the GelPad still attached to the larger plastic film, align the three holes in the GelPad with the three terminals on the Sensor, as shown. Make sure that the shape of the GelPad fits the Sensor groove. Attach the GelPad to the Sensor. Press down firmly.
  4. Remove the other plastic film. Ensure that the three transparent gel dots (covering the holes) remain attached to the GelPad.




  1. Locate the temporalis muscle by placing two fingers on your temple and clenching your teeth – you will feel the muscle pushing out.
  2. Remove the Sensor from the Docking Station and place the Sensor with the GelPad directly on your temple, as shown. We suggest using a mirror to help you find the correct placement. Ensure that no hair is trapped under the GelPad.
    When the Sensor obtains good contact with the skin, it will emit a single beep, informing you that the system is ready. The Sensor only beeps one time. If you remove the Sensor from your temple, you need to place the Sensor in the Docking station before you place the Sensor on your skin again. Otherwise the Sensor will not emit the beep.
  3. The stimulation of the Sensor is set up at level 0 when you use it for the first time.  You can adjust the stimulation level by pushing either the + or the – buttons located at the ends of the Sensor, as shown. A stimulus pulse is emitted when you press either of the buttons. When you reach the low end (level 0) or the high end (level 9) of the stimulation range, a beep is emitted to inform you. The right level is where you are just able to feel the stimulation (without any pain or disturbance). The Sensor keeps the stimulation level from your last treatment. Usually, you will therefore not have to adjust the level each time you set it up. To make sure that the stimulation level is set correctly for you, you can simply clench your teeth to verify the strength of the impulse.  

You are now ready to go to sleep!


Note: Your doctor or dentist will be able to advise you as to the most appropriate way to continue using GrindCare to best manage your particular condition over the long term. For an initial period of 3 to 4 weeks, GrindCare device is usually used every night until you start to experience a reduction in grinding or clenching. You can then adapt the frequency of usage to keep your bruxism under control as recommended by your doctor or dentist.


3. When you get up



  1. Remove the Sensor from the temple.
  2. Remove the GelPad from the Sensor and discard it.
  3. Place the Sensor in the charging bay of the Docking Station. The green LED’s will start to blink indicating that the Sensor is charging. See paragraph 'Charging level indication' in section 'Getting started'.
  4. The blue LED below the charging LED’s shows when data is being transferred from the Sensor to the Docking Station. The LED flashes when data transfer is in progress. Once completed, the blue LED will automatically turn off.


4. The GrindCare App

The GrindCare solution comes with a GrindCare app for your mobile device that can be downloaded free of charge in the Apple App Store or Google Play.  With the GrindCare app, you can review your night’s grinding, enter diary notes and track your progress. The GrindCare app is optional and for information purposes only.

In the morning, you can transfer the previous night’s data from the docking station to the app. To do so, make sure that the docking station is connected to a power outlet. Then place the sensor in the docking station and open the app to establish a connection, which will be indicated by a green band at the top of your screen. The data will then be automatically transferred, and you will be able to browse the app at your convenience during the day.


Home: On the main screen you will find an overview of your grinding and clenching activity from the most recently transferred night’s data.  The bars indicate when and how often the GrindCare Sensor detected grinding or clenching during your sleep.  The time at the top indicates how long you slept with the GrindCare Sensor turned on, and the number on the top right indicates the total number of detected grinds or clenches for this particular night.

History: In the history section, you will be able to review the progress of your nightly grinding or clenching activity along with how you felt on each corresponding morning and track improvements since you began using your GrindCare device.  Swipe the screen to scroll back in time. By selecting and pressing down continuously the bar of a particular night, you can access the more detailed results from that night.

Diary: Using the diary function, you can select a smiley emoticon corresponding to how you felt upon waking up.  In addition, you can add observations regarding any specific circumstances, life events or activities that you may later be able to correlate with your grinding data to help you identify your primary bruxism triggers.
