Before you begin

Step-by-step instructions

  1. 1

    Brush and prepare your teeth

    Thoroughly brush your teeth with your regular toothpaste. Make sure your teeth are completely dry before applying the gel — saliva can dilute the gel and reduce effectiveness. Gently pat your teeth dry with a clean tissue if needed, and avoid rinsing with water right before application.
  2. 2

    Load the trays

    Dispense approximately ½ ml of gel per arch (upper or lower tray).
    • Place small dots or a thin line of gel along the front (facial) surface of the tray where it contacts your teeth.
    • Avoid overfilling — excess gel can irritate gums or waste product.
    • One syringe typically provides multiple applications — use the markings or estimate carefully.
  3. 3

    Insert the trays

    Seat the loaded tray firmly over your teeth. Gently bite down and use your fingers to press the tray into place for a good seal. Wipe away any excess gel that squeezes out onto your gums with a clean finger or tissue — do not swallow.
  4. 4

    Wear time

    Leave the trays in place for at least 20 minutes. You may wear them up to 30–60 minutes per session if tolerated well (follow your dentist's or product-specific guidance). Do not eat, drink, or smoke while the trays are in.
  5. 5

    Remove and clean up

    Remove the trays and rinse your mouth thoroughly with water. Clean the trays with cool water and a soft toothbrush or denture cleaner — avoid hot water, which can warp them. Spit out any remaining gel; do not swallow.
