Yоur pаtient Mr. Jаcksоn infоrms you thаt he has an appointment with the dentist following his prophylaxis appointment to have two tooth-colored restorations replaced on #8 and #9. Mr. Jackson asks about vital tooth bleaching and informs you that he hopes you will have time to take the impressions as soon as you are done so he can pick up his bleaching trays tomorrow. Mr. Jackson's chart indicates that the dentist has approved vital tooth bleaching for the patient, and he is ready to start. What concerns do you have about this treatment plan, if any?
