A mouthguard, serving to protect the teeth, temporomandibular joint, head and neck, is user formed of silicone material by placing uncured silicone material in a tray, impressing the upper teeth into the material, removing the tray before complete curing of the material, impressing the biting or occlusal surfaces of the lower teeth into the material, and permitting the material to cure. The tray is flexible and may comprise two or more separate or separable pieces to facilitate removal. The tray is proportioned to contain a sufficient quantity of silicone material to provide effective thickness of material both outwardly and inwardly of the teeth in the complete mouthguard, and to be sufficiently deep to conform the guard at least to the gingival line without penetration of the teeth through the material into contact with the bottom of the tray, and at the same time to contain sufficient material to permit a certain excess thereof to be smoothed and spread, by use of the fingers, lips and tongue, across the upper outer gum surface and partially or completely across the hard palate. The width of the tray is sufficient, specifically, to provide sufficient material to permit the lower teeth to be sufficiently embedded in the material prior to curing that, when cured, the mouthguard will provide effective occlusal support.

Tray means for holding a mass of dough-like uncured silicone material in the shape of a rod bent into a U shape while forcing the upper teeth into such mass and thus forcing the inner, outer and lower surfaces into conforming contact with the whole inner trough-defining surface of such tray means, said tray means comprising two separable troughed portions, one of which has an inner surface in such contact with at least approximately one half of the total of such inner, outer and lower surface area, and the other of which includes an exposed outer Surface and is separately movable away from such first portion and from such mass without disturbing such contact between said mass and said inner surface of said first portion.
