Abstract：
:A case study is presented that described an acute flare-up of a tooth following a vital bleaching procedure. The case illustrates (a) the importance of assessing the pulpal and periradicular status of a tooth prior to any vital bleaching procedure; and (b) the alteration of the local adaptation syndrome by the bleaching agent.
