A clinical study was conducted at the offices of an independent, well-respected expert. This dentist was the former president of the Belgian Academy of Esthetic Dentistry (BAED) and member of several academies of esthetic research and has been performing whitening procedures for more than 20 years. Results from this study on the effectiveness of iWhite Instant showed an average of 4.8 shades, while some patients had results of 8 shades after one 20 minute treatment!
