Abstract: Apparatus comprising: a holder for receiving a mouldable element and for insertion into a user's mouth to allow the user to apply a biting force to the mouldable element to provide close adaptation to the user's teeth, the holder comprising: opposed sidewalls extending from a base, wherein at least one of the opposed sidewalls is configured to move inwards when the user applies a biting force to the mouldable element received by the holder.

Abstract: An apparatus comprising: a tray for receiving a mouldable element and for insertion into a user's mouth to allow the user to apply a biting force to the mouldable element to provide an impression of the user's teeth, the tray comprising: opposed sidewalls extending from a base, wherein at least one of the opposed sidewalls is configured to move inwards when the user applies a biting force to the mouldable element received by the tray.

Abstract: A mouthguard (200) comprising: a base portion (210); an inner wall (212) extending from an inner edge (214) of the base portion; and an outer wall (216) extending from an outer edge (218) of the base portion, wherein an internal angle (234a-e) between the base portion and at least a portion of the outer wall is less than 90 degrees and an internal angle (232a-e) between the base portion and at least a portion of the inner wall is less than 90 degrees for gripping teeth of a wearer.

Abstract: The present invention provides a pacifier having a mouthpiece, a shield and an attachment. The shield defines an aperture and the mouthpiece and attachment are removeably connectable through the aperture thereby to hold the shield in place. Alternatively, the mouthpiece and shield may be connected in such a manner that they cannot be detached and reattached, and the shield and attachment are removeably connectable. Further alternatively, the mouthpiece and the shield are removeably connectable, and the shield and attachment are removeably connectable.

Abstract: The present invention relates to optimising the performance of a user at an activity by providing oral apparatuses which provide different separation distances between the user's upper and lower jaw and enable a user to select the apparatus which gives the optimal performance.

Abstract: The mouthguard of the present invention is provided with at least one recess in its base to receive a projection of a tool. The tool being made from a material which retains its shape at a temperature when the material of the mouthguard is ductile and susceptible to remoulding. By placing the mouthguard and tool together in the mouth of the user the thinning of the depth of the base of the mouthguard can be minimised whilst still enabling shaping of the mouthguard.
