An oral appliance (10) for repositioning the temporomandibular joint comprising a base portion (11) which is of generally U-shaped form to follow the jaw and teeth of a user and front and rear flang es (12 and 13) which define with the base portion (11) upper and lower channels (15 and 16) for receiving the teeth of the upp er and lower jaws. The base portion is of asymmetri- cal form on either side of the appliance (10) from the leading to the traili ng end thereof so as to substantially occupy uneven spac- ing between the upper and lower jaws of the user and cause the lower jaw to move into substantial alignment with the upper jaws.
