To End Your Teeth Grinding Symptoms, Follow These Steps:

  1. Fill coffee mug with half-cup of water; then warm – do not boil – in a microwave on high for 90-120 seconds. Carefully remove mug from microwave before placing GrindRelief into mug. Use caution – water will be hot.
  2. Submerge GrindRelief in heated water – with smooth, shell-side down – for 90 seconds to two minutes, or until device is translucent.
  3. Remove GrindRelief. Be sure it is not too hot to the touch.
Forming on Lower Teeth
  1. While looking into a mirror, place the GrindRelief over lower front teeth using the white central power bar as a guide to center the device; use fingers to press down lightly on the device to gently seat it on the teeth.
  2. Bite down to further seat the GrindRelief until pressure is felt, mainly on the upper and lower front teeth. DO NOT use excessive force.
  3. Open mouth and use the middle and index fingers of each hand to hold both sides of GrindRelief down firmly on your lower teeth for 90 seconds.
  4. Remove GrindRelief and cool in tap water for 30 seconds; then reinsert in mouth.
  5. Sharp and uncomfortable edges may be trimmed with scissors or a nail file; edges are best trimmed when slightly soft.
Forming on Upper Teeth

Same as lower but be sure to push GrindRelief back as far as possible against front teeth then gently bite teeth together bringing lower teeth forward to bite on power bar for 90 seconds. Complete cooling and fitting as described above in steps 7-8.  

  • After final cooling, if the GrindRelief is too tight or if the edges pinch, do not force in your mouth. Simply reheat in microwaved water for 10 seconds and reseat, as described above in steps 4-6.
  • Wash GrindRelief, store in case and protect from high temperatures.
  • You may refit GrindRelief as many times as you want – by softening it in heated water and refitting it as described above in steps 4-6.

What to Do If Your Night Guard is Too Tight

First you should reheat the water in the microwave for at least 90 seconds. Then place your GrindRelief on the spoon into the water for 5 seconds. Then reposition device on your teeth and lift on and off several times. You may repeat this as many times as you like to ensure it’s a comfortable fit. GrindRelief is designed to fit you!

What to Do If Your Night Guard is Too Loose

If your night mouth guard is too loose, you may re-soften and fold thermoplastic back into the center of the tray. You may then refit your mouth guard by following the instructions again from the beginning. You may do this as much as needed. Be sure not to move the teeth guard for the first 90 seconds. When properly fit, GrindRelief dental guard will fit without excessive force, and fit snugly. GrindRelief is comfortable and effective.

What to Know About Your Dental Guard

Your upper and lower back teeth should not come into contact. The main force should be felt at the mid-line between the upper and lower front teeth at the Central Power Bar, relieving muscle pressure by 60 percent. Store GrindRelief in the case provided, brush it before storing and keep it away from pets. You can occasionally disinfect your GrindRelief with hydrogen peroxide. Also, watch our instruction video on GrindRelief to see how easy it is to customize your night guard for grinding teeth.
