Claim 28:
29. A device comprising:
a deformable elastomeric gum sealing portion for covering a gum ridge;
one or more hardened sections coupled to the gum sealing portion;
a distal tooth sealing portion, wherein the gum sealing portion and the distal tooth sealing portion define a gap between at least a portion of the device and the tooth and surrounding gum over which the device lies; and
at least one fluid conduit portion for passing a fluid into or out of the treatment cavity;
wherein, when the device is placed in a patient's mouth over a plurality of teeth, (i) the gum sealing portion contacts and deforms against a gum ridge of the patient for forming intimate contact with the gum ridge, and (ii) the distal tooth sealing portion deforms against a distally located tooth or teeth for substantially defining a seal at the distal tooth or teeth, so that a fluid can be introduced and/or removed from the treatment cavity while maintaining a seal with both the deformable gum portion and the distal tooth sealing portion, and
wherein the deformable gum sealing portion is collapsible such that, when an internal vacuum force is applied to the treatment cavity, the deformable gum sealing portion collapses while the one or more hardened sections resist collapse,
wherein the one or more hardened sections comprise one or more rigid stiffening elements,
wherein the one or more rigid stiffening elements form an endo-skeleton by being partially or fully embedded inside a soft body dental cover section, and
wherein the soft body dental cover section is over-molded over the one or more rigid stiffening elements.
