Our teeth whitening works by removing stains and discolorations from the enamel and dentin. The outer layer of the tooth is called enamel, and beneath the enamel is dentin. Enamel is thin and usually much lighter in color, while dentin is darker and makes up most of the tooth. Enamel can lose its color over time simply from age, but also from things like coffee, tea, tobacco, and other foods and beverages. Also, as we get older, our enamel can thin out, causing more dentin to show through, making the overall appearance of the tooth look less brilliant. The active ingredients in our whitening gels oxidize the discolored molecules deep down in your teeth to remove stains and whiten your smile comfortably. Plus, our original, patented formula is sticky and viscous, preventing the whitening gel from seeping out and ensuring your trays stay in place to brighten up your teeth.
