After the procedure, patients should follow a so-called “white diet” and avoid colored beverages such as red wine, which may cause enamel discoloration. Some individuals may experience temporary tooth sensitivity, but it usually subsides quickly. Using gentle oral hygiene products (toothpaste and mouthwash) can help minimize discomfort.
The whitening effect lasts from several to over a dozen months, depending on individual predispositions and lifestyle. It is recommended to limit strong tea and coffee consumption and to refrain from smoking.
