An apparatus for monitoring tooth whitening treatments and status is shown in the form of a toothbrush with at least one panel with a scale of whiteness indicators. Whiteness indicia can be a removable or permanent insert disposed in a slot in the head, body or handle of a transparent toothbrush or an inlay in the surface of the brush. Other information such as appointment times, dentist information, instructions and images can be placed on the inserts. Comparison of the indicia with the teeth allows the user to evaluate the progress of treatments. |
