Dental shade guide R-20

The R-20 is the teeth shade guide that we recommend for teeth whitening. It is used to compare the color of the teeth before and after a teeth whitening treatment. It has 20 shades that range from 2 to 40. Each shade on the guide is arranged from light to dark and it comes in a beautiful storage case. The R-20 is sturdy, easy to sanitize, and easy to use. Plus, customers feel more positive about their results when you can tell them they went from a “34” to a “22”.
