Before you begin

Step-by-step instructions

  1. 1

    Brush first, then open one pack

    Brush your teeth with Gel 1100 and rinse. Open a single tray pack when you're ready to start — each pack holds one upper tray (marked U) and one lower tray (marked L), already filled with gel. There is nothing to load or measure.
  2. 2

    Seat the upper tray

    Position the upper tray over your teeth, bite down firmly, then suck against the tray for about two seconds. That draws the tray tight and seats the gel against every surface.
  3. 3

    Peel away the outer tray

    Pull off the colored outer tray and discard it. The thin white inner tray stays behind, molded to your teeth. Then repeat steps 2 and 3 with the lower tray.
  4. 4

    Wear for 15–20 minutes

    Leave both inner trays in place for 15 to 20 minutes.
    • Don't eat, drink, smoke, or use tobacco while the trays are in.
    • Never wear the trays while sleeping.
    • Some gel may be swallowed during normal use — that's expected. If a large amount is swallowed, drink water and contact your healthcare provider.
  5. 5

    Remove, discard, and brush

    Take out both trays and throw them away. These trays are single-use — they are not designed to be refilled or re-worn, so never save one for a second session. Rinse your mouth, then brush with Gel 1100 so the nano-hydroxyapatite goes to work remineralizing enamel between sessions.
