A bite opener for use during orthodontic treatment has a base for mounting on a lingual side of a tooth, as well as at least one occlusal portion for contact with an opposing tooth so that other teeth (such as molar teeth) can be extruded. In one embodiment, the bite opener has a channel extending between a mesial section and a distal section, so that the sections can be squeezed together when desired to debond the bite opener from the patient's tooth. In other embodiments, the bite opener includes a bite plate connected to the body, and the bite plate is made of a material softer than the body to enhance patient comfort when the jaws are closed. Optionally, the bite plate is detachably connected to the body so that the bite plate can be removed before debonding the body from the tooth.
