Are there foods to avoid after whitening?

Yes, for the first 24 to 48 hours after whitening, the tooth surface is especially prone to staining, so you should avoid darkly colored foods. 1) Foods to avoid — coffee, black tea, wine, curry, cola, kimchi stew, and other strongly colored foods, as well as smoking. 2) Recommended — water, milk, white fish, white rice, and other lightly colored foods. 3) If you do eat colored foods, it helps to rinse with water or brush right away. Managing this short window carefully helps maintain your whitening results, and continuing to limit staining foods afterward will make the effect last even longer.
