Claim 19:
20. A method for executing dental treatments, comprising:
positioning a mouthpiece comprising a dental arch soft body cover section over a user's teeth and surrounding gums;
applying a fluid sealed vacuum to a treatment cavity formed by the dental arch soft body cover section so that a fluid sealed treatment cavity having a pressure below ambient pressure is formed around the teeth and surrounding gums;
flowing one or more treatment materials into the fluid sealed treatment cavity; and
flowing out the one or more treatment materials from the fluid sealed treatment cavity to a waste container,
wherein the dental arch soft body cover section comprises an arch-shaped portion and separate hardened sections coupled to the arch-shaped portion,
wherein the arch-shaped portion is composed of one or more soft elastomeric materials that have low shore hardness such that the arch-shaped portion collapses when exposed to the vacuum pressure due to collapse of the one or more elastomeric materials,
wherein the separate hardened sections are composed of rigid materials that do not collapse when exposed to the vacuum pressure, thereby enabling selected/differential collapsibility of the mouthpiece when exposed to the vacuum pressure,
wherein the separate hardened sections further comprise:
one or more rigid buccal stiffening elements disposed on, and connected to, a buccal surface of the dental arch soft body cover section; and
one or more rigid lingual/palatal stiffening elements disposed on, and connected to, a lingual/palatal surface of the dental arch soft body cover section,

wherein the one or more rigid buccal stiffening elements do not collapse when a vacuum force is applied to the fluid sealed treatment cavity and wherein the one or more rigid lingual/palatal stiffening elements do not collapse when a vacuum force is applied to the fluid sealed treatment cavity, thereby maintaining an empty space between the teeth and the internal walls of the cover section surrounding gum ridges,
wherein the one or more rigid buccal stiffening elements are connected to a mouthpiece coupler for the mouthpiece, and
wherein the mouthpiece coupler comprises one or more vacuum tubes for generating the fluid sealed vacuum.
