Abstract
Compositions and methods for whitening the teeth of a patient or subject are described for performing a dental prophylaxis or cleaning procedure during which at least one tooth whitening composition is applied to the surface of a stained tooth, said compositions and methods resulting in a tooth color change that is noticeable to the patient or subject immediately following the procedure. The novel procedure allows for a high degree of tooth whitening to be safely achieved in a short period of time while under the control of a dentist, dental hygienist, or other dental professional, and which at least partially coincides with the performance of a dental prophylaxis or cleaning procedure in order to save significant clinical operatory chair time compared to cleaning and whitening procedures that are performed in non-overlapping time frames or appointments.
