Summary

This study looked at whether the way a retainer is made (its margin design) changes how happy people are with at-home tooth bleaching. Forty adults who had finished Invisalign treatment used special retainers with different designs on each side of their mouth for two weeks. The study measured satisfaction, how well the teeth whitened, and any tooth sensitivity or gum irritation.
