For best results:
- Brush your teeth thoroughly then dry them with a clean cloth before applying the teeth whitening gel to them
- Generously apply gel from whitening pen onto your teeth, avoiding gum area
- Keep smiling until you put your mouth tray in (if you close your lips you will wipe gel off your teeth)
- For best results do (2) 8 minute sessions back to back for 5-7 consecutive days. If you are experiencing any sensitivity; take a break from sessions for a few days.
