Title: Teeth color maintenance composition for addition into beverages

Description:
FIELD OF THE INVENTION 
     This invention relates to the field of tooth whitening and color maintained using oxygen release and a hydrophilic food additive introduced into beverages that discolor teeth. 
     BACKGROUND OF THE INVENTION 
     Teeth whiteners, also known as teeth bleaching agents, are available to consumers in many different forms. There are systems that are available only through a dentist, involving high strength peroxide solutions. There are also application protocols involving peroxide gels dispends in trays or adhesive trays or adhesive strips. All of these protocols involve removing the stains once they are embedded into the teeth. Below is a list of references that may or may not be material to the prosecution and may or may not be prior art.

     SUMMARY OF THE INVENTION 
     The present invention is designed to overcome the deficiencies of the methods discussed above. It is the object of the present invention is to provide a process and composition to eliminate or reduce the staining effect from beverages. 
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     The invention relates to a new approach to prevent teeth from stains in beverages such coffee, tea, wine, sodas and juices. This invention is a maintenance system to preserve the color of teeth. The scope of the invention presently disclosed extends beyond the embodiments presented herein. 
     In preferred embodiments, the composition is a liquid, table or powder that releases oxygen when introduced into a beverage. The oxygen releasing agent (sodium perborate, carbamide peroxide, chlorine dioxide or hydrogen peroxide) is preferably present at a concentration from about 1%-10%. Water is present at 90% to 99%. Oxygen gas may also be infused into the solution. The invention is added into beverages, the oxygen release leads to a breakdown of teeth staining molecules. By breaking down the discoloring component of the beverage prior to its contact with teeth, teeth staining is reduced.
