Should you apply Whitestrips twice a day to speed up results, or stick to a 20-day consecutive schedule?

Treatment Rules:
- Standard Schedule: Apply once daily for 45 minutes for 20 consecutive days.
- Double Applications: ⚠️ Do NOT apply two strips back-to-back in a single day. Over-exposure to hydrogen peroxide causes severe gum burning and nerve pain.
- Rest Days: Taking 1 day off per week if teeth feel sensitive will not decrease final whitening results.
