How to Maintain Your Bright Smile After Treatment
By Dr. Jane Collins | December 03, 2025
Congratulations! You've completed your whitening treatment and your smile looks fantastic. But teeth whitening isn't permanent. Without proper care, stains can start to creep back in within a few months.
The good news is that maintenance is easy. With a few simple habits, you can keep your smile bright for years, not just months.
The 'White Diet' (First 48 Hours)
The first 48 hours after a professional whitening treatment are critical. Your enamel pores are still open and vulnerable to staining. Stick to a 'White Diet'—foods that are white or clear.
- Eat: Chicken, rice, pasta (white sauce), potatoes, bananas, yogurt.
- Avoid: Coffee, tea, red wine, tomato sauce, soy sauce, berries, chocolate.
Daily Habits for Long-Term Success
- Use a Straw: When drinking staining beverages like iced tea or coffee, use a straw to minimize contact with your front teeth.
- Rinse After Eating: You don't always have to brush. A quick swish of water after a meal helps wash away pigments before they settle.
- Whitening Toothpaste: Swap your regular toothpaste for a whitening formula. These contain mild abrasives that polish away new surface stains before they set.
Touch-Up Treatments
Even with perfect habits, natural aging will slowly darken teeth. Ask your dentist about a 'touch-up' kit. Using your custom trays for just one or two nights every 6 months is usually enough to bounce your smile back to its brightest shade.
