  • Brush and floss your teeth before insertion.
  • When placing guard in. If guard feels tight, place the appliance in warm water for 15-20 seconds. This will quickly soften the inner lining allowing for ease of placement.


  • Upon removal, the appliance may be cleaned with a soft toothbrush and toothpaste. Or antibacterial hand soap.
