✔ Natural Whitening Methods

1. Baking Soda (Sodium Bicarbonate)

• Mild abrasive that removes stains on enamel
• Natural alkalinity helps reduce oral acidity
• Use: Mix ½ tsp with water into a paste, brush 2–3× per week
• Luka note: Don’t overuse or you’ll scratch enamel.

2. Activated Charcoal

• Adsorbs surface stains
• May reduce plaque temporarily
• Use: Dab lightly, 1–2× per week
• Luka warning: Too abrasive for daily use.

3. Banana Peels

• Inside of peel contains trace minerals like potassium & magnesium
• Can help polish surface stains gently
• Use: Rub inner peel on teeth for 1–2 minutes, rinse.

4. Oil Pulling (Coconut or Sesame Oil)

• Reduces harmful bacteria
• Helps reduce plaque and mild staining
• Use: Swish 10–15 minutes daily or a few times weekly.

5. Strawberries + Baking Soda (Malic Acid Polish)

• Malic acid brightens teeth
• Use: Mash strawberry + pinch of baking soda, apply 1× weekly.

6. Hydrogen Peroxide (Diluted)

• Natural bleaching agent
• Use: 1.5–3% diluted rinse, 1–2× per week
• Luka note: Do NOT swallow. Avoid daily use.
