Benefits of technology

[0028] The present invention together with the above and other advantages may best be understood from the following detailed description of the exemplary embodiments of the invention.

Problems solved by technology

In particular, food products, tobacco products and fluids such as tea and coffee that one consumes tend to stain one's teeth.
These staining and discoloring substances can then permeate the enamel and cause noticeable discoloration of one's teeth.
Even treatments with compositions not known to increase tooth sensitivity in most patients might still cause sensitivity in patients more prone to such sensitivity tendencies.
(The pH of Tooth-Whitening Products, J Can Dent Assoc, 66:421-6, 2000), may also lead to further de-mineralization of the tooth, decreasing its hardness.
