After Teeth Whitening: The 48-Hour ‘White Diet’ and What Actually Sticks

Post-whitening enamel is temporarily porous. The chromogens in coffee, tea, red wine, curry and turmeric enter more deeply during this window and set your teeth back several shades within a week. ### The 48-hour white diet **Allowed**: milk (labneh, laban), water, white cheese, chicken breast, rice, potatoes, cauliflower, egg white, pasta with white sauce. **Not allowed**: coffee (including karak), gahwa, black/red tea, red wine, cola, energy drinks, all curries, turmeric, saffron, red berries, tomato-based sauces, soy sauce, balsamic. Strict for 48 hours; loosen gradually for the next 5 days. ### Manage sensitivity - Sensodyne Repair & Protect or Colgate Sensitive Pro for 7 days - Avoid cold beverages during the first 24 hours - If your dentist supplied desensitising gel (5% potassium nitrate), use nightly for 3 nights ### Long-term retention - Drink coloured beverages through a straw when practical - Rinse mouth with water after coffee/tea - Repeat home-tray touch-up (one 30-minute session) every 4–6 months - Six-monthly professional scaling to remove extrinsic staining ### Habits that undo whitening in 3 weeks - Shisha (heavy chromogen source and pore-opener) - Chlorhexidine mouthwash daily (its yellow-brown staining is notorious) - Iron drops (common prenatal supplement) — take through straw ### When to re-whiten - 12–24 months for most patients if maintenance is followed - 6 months for heavy coffee/gahwa drinkers - After any tetracycline-era antibiotic exposure ### Cost of maintenance Home-tray touch-up syringes: AED 90–180 each. Whitening pen (Philips): AED 250–400. Professional in-office refresh: AED 700–1,200 (half the initial cost).
