💧 3. Hydrogen Peroxide Rinse (Diluted)
- How it works: A mild bleaching agent that lifts surface stains.
- How to use: Mix equal parts hydrogen peroxide (3%) and water. Swish for 2–3 minutes, then rinse thoroughly.
- Use occasionally, as frequent use may cause sensitivity.
⚠️ Safety Tips:
- Avoid brushing immediately after acidic treatments (like lemon) to protect enamel.
- Don’t overuse whitening methods—2–3 times per week is enough.
- Always rinse well and follow up with regular brushing.
