The shade of your teeth will brighten up to 7 shades whiter, with an average improvement of 1-3 shades with each 20-minute session. An Individual’s results will depend on their current tooth shade, amount of sessions completed, and the overall health of their teeth. The result will be a whiter, healthier looking smile. Everyone’s teeth are different and will only get to their most natural white shade. We recommend 3 sessions of 20-minutes for optimal results to remove years of staining.
