The guard 1 includes generally a base member 2 having a generally U-shaped form corresponding to the outline of a jaw of a user defining an upper channel 10 within which an upper row of teeth of a user can be received. The guard also discloses a teeth engaging element 3, associated with the channel 10 which is made of a material able to be user conformed or user moulded to the mouth of the user. The guard also includes shock absorption means associated with the base member 2 for absorbing impact shock.
