This method of teeth whitening is preferred over a tray system in which a small tray is filled with whitening solution and then placed over the top of the teeth because teeth whitening strips are not bulky or messy and typically do not trigger a person's gag reflex. A person also can converse normally while wearing these strips. Even so, a user must refrain from eating, drinking or smoking while these strips are in place and for at least 30 minutes after their removal.
