  • Aqueous tripolyphosphate salts whiten teeth by dissolving susceptible stains into solution.
  • Embodiments of the present invention provide delivery methods that allow greater contact time for a greater stain dissolution effect upon the teeth.
  • a whitening film 10 utilizes a thin water insoluble polymeric or plastic flexible backing material 12 to which is applied a water soluble gelatinous layer 14 that contains the active ingredient tripolyphosphate salts.
  • the finished whitening film 10 is applied to the teeth such that the water soluble gelatinous layer 14 including the active ingredient comes into contact with the tooth surface.
  • the water insoluble backing material 12 faces away from the teeth and functions to protect the gelatinous layer 14 from the dilution effects of saliva.
  • the finished whitening film 10 is designed to be worn for more than one minute; other embodiments call for treatment times comprising: 15, 30, 60, 120, 180, 240, 360 minutes and any other suitable application time.
  • An overnight whitening film also comprises an embodiment of the invention, wherein the user wears the whitening film while they sleep.
  • the user can create a stain removal regime lasting from days to weeks to achieve a desired whiteness; the film is disposable and can be replaced multiple times per day if desired.
  • Embodiments of the thin polymeric or plastic backing material 12 include but are not limited to: polyethylene sheet, polypropylene sheet, polyurethane sheet, nylon sheet, wax sheet, parafilm sheet, PVC sheet, and any other useful water insoluble sheet material.
  • the gelatinous composition 14 that contains the active ingredient may include a liquid component, a polymeric thickener, and a component that adjusts pH.
  • the gelatinous composition that contains the active ingredient may also include additional components such as a sweetener, flavoring agent, fluoride, anti-tartar agent, anti-microbial, and any other useful ingredient.
  • Embodiments of thickening agents include but are not limited to: PVP, polyethyl oxazoline, carboxypolymethylene, guar gum, xanthum gum, silica powder, fumed silica, polyethylene glycol, polypropylene glycol, and any other useful thickening agent.

  • the gel is spread as a thin layer over the water-insoluble polymeric backing material 12 and is allowed to dry into a gelatinous state, forming the gelatinous composition 14.
  • the final whitening film 10 is cut into a size to fit at least some portion of the teeth and packaged in airtight containers.
  • a "gelatinous" material as used herein has physical properties somewhat similar to the confection known as gummy worms (i.e. , flexible and soft enough to conform to a tooth surface without cracking or fracturing, yet firm enough that it will not coalesce with a separate gelatinous material when placed into mutual contact).
  • Another embodiment of the invention combines the stain removing ability of tripolyphosphate with the whitening/oxidation ability of peroxide into the gelatinous composition 14. To our surprise we have found the sodium
  • tripolyphosphate to be compatible with peroxide and the two can remain soluble together in solution. Therefore any combination of peroxide and sodium/potassium tripolyphosphate is within the scope of this patent. The ideal combination would maximize the concentration of both ingredients with respect to their solubility within the polymeric thickener matrix.
