A bite block device for use with intrabuccal instruments having a generally U-shaped central body. A lower vestibular rim extends from an outer periphery of a bottom surface of the generally U-shaped central body. A lower lingual rim extends from an inner periphery of the bottom surface of the generally U-shaped central body. An upper vestibular rim extends from an outer periphery of an upper surface of the generally U-shaped central body. An upper lingual rim extends from an inner periphery of the upper surface of the generally U-shaped central body. The upper surface, the upper vestibular rim, and the upper lingual rim are anteriorly discontinuous for a common length to form an intrabuccal instrument channel therethrough.
