After teeth whitening, it is important to keep your teeth sufficiently moist. Therefore, they should consume a lot of fluid. Water or milk are particularly well suited. Other drinks such as coffee, tea or red wine should be dispensed with at least 48 hours after treatment. Furthermore, your teeth should stay away from knowingly dying foods for 2 days. Products such as dyed toothpaste, mouthwashes or lipstick can also negatively affect the result.
