At-home Teeth Whitening Kit Adds Light Activation Tool
At-home teeth whitening has taken another step toward promising professional-grade results by adding an activating light to the package. The 1-Hour White version of Luster Premium WhiteTM, from Dentovations, Inc., advertises a "super whitening light" to accelerate the action of its "super whitening gel."
The description on the Dentovations Web site sounds about the same as that found on most dentists' teeth whitening pages. The consumer first uses an "accelerator mouth rinse," then applies the gel, then shines the light on the teeth in two-minute increments for up to one hour, depending on the desired level of whiteness.
Likely Ingredients Common Knowledge
Like most dentists' Web sites, the Dentovations site does not reveal the contents of the rinse or gel, or anything about the light. Since the details of the professional systems have leaked out, it's probably safe to assume the 1 Hour White kit is similar.
The typical teeth whitening rinse has ingredients to remove residue left on the teeth after brushing, and to kill bacteria, which can interfere with the effectiveness of the active ingredient of the gel, either hydrogen peroxide or carbamide peroxide, which breaks down in the mouth to form hydrogen peroxide.
Peroxide Is Key to the Process
Peroxide is the key to the process. It is mildly acidic, so removes stain material from the surface of the teeth through oxidation. It is often implied that dentists use a stronger solution of peroxide than is available for home use.
The purpose of the light is to intensify the action of the gel. The devices most commonly used by dentists emit blue wave length light, known to excite the movement of peroxide molecules, but cool enough to cause no damage to tooth material.
Of course, the primary reason to use an at-home whitening product is price. Dentovations sells the 1-Hour White system online for $40, compared to paying $250 or more to have a whitening procedure at the dentist's office.
