Apply commercial whitening strips or gels

Over-the-counter whitening strips and gels contain peroxide-based bleaching agents (typically 10% carbamide peroxide or 3-6% hydrogen peroxide) at concentrations safe for home use. Most produce visible results within 1-2 weeks of daily application.

Steps

1. Follow product instructions carefully — most strips are applied for 30 minutes daily over 1-2 weeks.
2. Avoid staining foods during treatment — coffee, tea, red wine, and dark berries can counteract whitening.
3. Stop if sensitivity develops — some temporary sensitivity is normal, but persistent pain means you should consult a dentist.

Tips

• ADA-accepted brands (such as Crest 3D Whitestrips) have been independently verified for safety and efficacy
• Results typically last 3-6 months depending on diet and habits
• Store strips in a cool, dry place; heat degrades peroxide potency
