A customizable and reusable mouthpiece for diving use having a passageway-forming front member extending from a proximal in-mouth end to a distal outside end and a U-shaped formable back member is described. The back member provides a hollow cavity portion located in the bitewing section that may be partially filled with a gel-like or other suitable substance configured to provide custom moldability at substantially all points of contact between the mouthpiece and the teeth such that the mouthpiece is securely gripped by the teeth. The mouthpiece requires pressure relief channels so that air or fluids may enter into and be forced out of the hollow cavity providing a bellows-like action that provides a means for the bitewing and materials of composition to return to essentially its original shape. Reusability of the mouthpiece, more specifically the bitewings is directly related to the choice and combination of materials, dimensioning and processing.

What is claimed is: 1. A reusable customizable mouthpiece wherein a core member comprises: a substantially rigid non-formable core that provides a rigid shape to said mouthpiece extending from a proximal in-mouth end toward a position short of a distal outside end and forming part of a horizontal passageway with a U-shaped member that forms said complete mouthpiece of a type with a front portion forming a breathing hole and at least one bitewing that is customizable; wherein said bitewing initially provides a formable hollow cavity, wherein said formable hollow cavity may be empty, partially, or completely filled with an elastomeric gel, and wherein said bitewing extends proximally beyond said formable hollow cavity and may form a top cavity end and a bottom cavity end that may be sealed and subsequently trimmed; and wherein a channel or channels provide access to said distal outside end the outside the users mouth that extend from said formable hollow cavity laterally toward said distal outside end from said front portion through a lateral wing toward such that said channel allows for fluid such as a gas or a liquid to flow into and out of said formable hollow cavity; wherein channels that include a disc groove having disc, wherein disc groove for placement of a customizable disc capable of providing a barrier to the passage of fluids and also allows for displacement of said fluids; said formable hollow cavity comprising an integral set of said bitewings with formable upper and lower surfaces and flanges having upwardly-extending and downwardly-extending flange portions with upper and lower edges, respectively, and providing inside surfaces spaced for formable engagement with opposite side surfaces 30 of said user's teeth, and wherein said formable hollow cavity may or may not contain an elastomeric gel that allows for complete or partial return to an original shape and dimension of said bitewing after said mouthpiece has been used for engagement with said user's teeth by one or more users. 2. The reusable customizable mouthpiece of claim 1, wherein said bitewings-include said formable hollow cavity and said channel allowing for said fluids to flow into and out of said formable hollow cavity, thereby causing a bellows-like process in that said fluid boosts or accelerates recovery of said bitewings to said original shape prior to compression by being allowed to flow back into said formable hollow cavity. 3. The reusable customizable mouthpiece of claim 1, wherein said bitewings of said mouthpiece including said core and said bitewings together are included in a complete mouthpiece, and said core and said bitewings are optionally all of one formable material composition and said formable material composition may optionally be a film or combination of said film and a substrate and is at least 0.1 millimeter thick. 4. The reusable customizable mouthpiece of claim 1, wherein said bitewings of said mouthpiece are of said formable material composition wherein said formable material composition includes a filling material such as said elastomeric gel or gel-like material such as a silicone gel and optionally includes nanoparticles that provide nanocomposites. 5. The reusable customizable mouthpiece of claim 1, wherein said channels are designed to ensure that said channels will retard blockage of said elastomeric gel during compression and release of pressure upon said formable hollow cavity of said bitewings and wherein openings of an end of said channels exists through a lateral wing to said distal outside end of said mouthpiece and an opposite end of said channel exists at an interface between said formable hollow cavity and said channel. 6. The reusable customizable mouthpiece of claim 4, wherein said bitewings of said mouthpiece are of said formable material composition wherein said formable material composition includes said nanocomposites that include SiC and optionally other inorganic particles with an average diameter of 700 nm or less or more depending on the ability of said inorganic particles to provide rebound to improve elastic memory of said bitewings. 7. The reusable customizable mouthpiece of claim 1, wherein said mouthpiece and said bitewings are optionally of said formable material composition optionally including nanoparticles that provide nanocomposites. 8. The reusable customizable mouthpiece of claim 1, wherein said mouthpiece and said bitewings are of said formable material composition wherein said formable material composition includes composites that include organic or inorganic or a combination of organic and inorganic materials including cellular or foamed versions as well as co-polymers, blends, as well as nanocomposites that include inorganics such as clays as well as fullerenes and nanotubes of fullerene based derivatives and essentially any composition with or without nanoparticles that allows complete memory recovery or at least full plastic recovery so that reusability can be achieved. 9. The reusable customizable mouthpiece of claim 1, wherein said formable hollow cavity returns to said original shape upon removal from said user's mouth. 10. The reusable customizable mouthpiece of claim 1, wherein said formable hollow cavity returns to original shape when a recovery temperature, Tr, that represents a temperature at which a material recovers said original shape during heating, is reached. 11. The reusable customizable mouthpiece of claim 1, wherein said bitewings are comprised of a material composition that may be initially formed by pressure, by heat and/or by vacuum molding and wherein said bitewings and said composition of said formable hollow cavity is reformable or wherein said elastomeric gel within said hollow cavity of said set of bitewings is reformable. 12. The reusable customizable mouthpiece of claim 1, wherein said bitewings includes a reduction in material requirements for said bitewings along an upper and lower portion of said bitewings that includes a complimenting customizable insert wherein said complimenting customizable insert composition may optionally be a film or combination of said film and a substrate, and wherein said film optionally provides an outer surface of said bitewings over a cellular or foamed formable material composition and said formable hollow cavity may be filled with a silicone gel. 13. The reusable customized mouthpiece as in claim 1, wherein said disc comprises an essentially rigid outer portion and a flexible inner portion so that said disc may act as a diaphragm. 14. A reusable customized mouthpiece as in claim 1, wherein channels are connected to an outer walled section of said mouthpiece that includes "balloon-like" pouches and wherein said pouches exist in an area that is toward a distal outside end of said mouthpiece such that said pouches can never be placed within a mouth portion of a diver.
