During the first 48 hours after teeth whitening, the enamel is particularly susceptible to staining, so it is recommended to follow the so-called “white diet.” You should avoid coffee, tea, red wine, brightly colored berries, beets, sauces, spices (such as curry), carbonated beverages, and smoking. It’s best to opt for neutral foods: water, dairy products without artificial colors, fish, chicken, eggs, rice, potatoes, and cauliflower. This helps lock in the results and prolong the whitening effect.
