An endoscopic device stabilizer for stabilizing an endoscopic device when inserted in a mouth of a patient. The stabilizer includes a body adapted for receipt within the mouth of a patient. The body has an opening sized and shaped for receiving the endoscopic device when the device is inserted in the mouth of the patient. The stabilizer also includes a clamp attached to the body selectively moveable between a locked position in which the clamp resists movement of the endoscopic device relative to the body and an unlocked position in which the clamp permits movement of the endoscopic device relative to the body.
