Professional whitening gives best results when combined with good aftercare.

For the first 48 hours:

1. Prefer a "white diet" (plain rice, curd, milk, idli, boiled vegetables)
2. Avoid coffee, tea, cola, red sauces, and tobacco
3. Use lukewarm water if teeth feel sensitive

Long-term maintenance tips:

1. Brush twice daily with a soft brush
2. Use dentist-recommended sensitivity toothpaste when needed
3. Reduce staining foods and rinse after consuming them
4. Plan periodic review visits for touch-up guidance

If sensitivity lasts beyond a few days, consult your dentist for personalized care.
