I agree with you. And I even found that the edges of teeth closest to the gums are still not totally white because of the material they put on there during the zoom treatment to protect the gums.

my dentist gave me a whitener bleach to use in my trays for 48 hours after my zoom tretment. I think it was called DayCare. He said to not eat staining foods for that time and continue to whiten at least twice each day for 48 hours for best results. He also said that clients pick up a whitening tube about every three months to keep them white. Hope that helps!
