4 Sensitivity Prevention Tips:
- Pre-Treat with Potassium Nitrate: Brush with a potassium nitrate toothpaste (Sensodyne) for 2 weeks prior to starting whitening.
- Do NOT Brush Immediately Before Applying: Brushing opens tooth pores and irritates gums. Wait 30 minutes after brushing before applying strips.
- Fold Lower Strip Carefully: Fold excess strip behind teeth rather than letting it rest on gum tissue.
- Use Every Other Day: If sensitivity occurs, switch from daily use to an every-other-day schedule.
