No, however, for most people, the treatment will last for many years. Your teeth have become stained in the first place from consuming various foods and beverages. Upon the completion of our initial Lab Direct™ Teeth Whitening Process, your teeth are restored to their natural white color. Exposure to foods, drinks such as coffee, colas and red wines, smoking and other consumables will gradually darken teeth again over time. You may want to periodically use our Lab Direct™ Teeth Whitening Process. After athe initial Lab Direct™ Teeth Whitening Process, most people do touchups at least once a month.
