Disclosed is a bite blocker device for preventing occlusion of an affected dentition. The channel of the bite block follows and engages a portion of the user's upper teeth, while a base portion, opposite the channel portion, follows and engages a portion of the user's lower teeth. The base portion and the channel are separated forming a gap between the user's upper teeth and lower teeth. The bite block is placed substantially opposite the affected tooth or teeth, the gap formed by the bite block preventing occlusion of the affected teeth.
