The results are amazing. I have never seen such a difference in my patients' appearance. We can see every detail, from the shape of their lips to the color of their teeth. This has been a great help with getting patients used to the new look before it is made permanent. There was no disliking the product or the process. It was an easy transition for my patients. They were all very happy with how much they liked the results. I think that the application could be more user friendly. For some reason it wasn't intuitive for me to use at first. But once I figured out how to use it, it became second nature to apply. The biggest problem we face is finding time to do the treatments. They are usually scheduled after lunch so it's hard to fit them into our schedule. My patients love seeing the difference in their smile. It makes them.
