SparkleMax™’s unique patented formula creates the appearance of brighter teeth. By combining light refraction technology with a unique whitening agent, SparkleMax™ allows the user with stained teeth to achieve an immediate appearance of a brighter smile. As the hydrogen peroxide in the gel is broken down, oxygen acts upon the organic deposits on your teeth and oxidizes them into a lighter color. This process makes the overall tooth color closer to the natural unstained tooth color. The structure of the tooth itself remains unchanged. Each pen contains a 30 day supply. Apply up to three times per day.
