## Abstract

An oral treatment device that includes a mouthpiece and an electromagnetic radiation source. In one aspect, the oral treatment device includes a mouthpiece comprising a curved wall having a concave inner surface and a bite platform extending from the concave inner surface of the curved wall to a distal end, the distal end of the bite platform extending continuously in a non-interrupted manner from a first end of the bite platform to a second end of the bite platform; an electromagnetic radiation source configured to emit electromagnetic radiation from the curved wall; and wherein the bite platform comprises a collapsible region such that the mouthpiece is alterable between: (1) a biased state in which the curved wall has a first curvature; and (2) a flexed state in which the curved wall has a second curvature that is different than the first curvature.

## Claims

### Claim 1

An oral treatment device comprising:
a mouthpiece comprising a curved wall having a concave inner surface and a bite platform having an upper surface and a lower surface, the bite platform extending from the concave inner surface of the curved wall to a distal end; and
an electromagnetic radiation source configured to emit electromagnetic radiation from the curved wall;
wherein the upper and lower surfaces of the bite platform extend from the concave inner surface; and
wherein the bite platform comprises at least one non-collapsible region and at least one collapsible region, the bite platform having a first thickness measured between the upper and lower surfaces of the bite platform in the at least one non-collapsible region and a second thickness measured between the upper and lower surfaces of the bite platform in the at least one collapsible region, the second thickness being less than the first thickness.

### Claim 2 (depends on 1)

The oral treatment device according to claim 1 wherein the upper and lower surfaces of the bite platform are flat in the at least one non-collapsible region of the bite platform and wherein the upper and lower surfaces of the bite platform are wavy in the at least one collapsible region of the bite platform.

### Claim 3 (depends on 1)

The oral treatment device according to claim 1 wherein the mouthpiece is alterable between: (1) a biased state in which the curved wall has a first curvature; and (2) a flexed state in which the curved wall has a second curvature that is greater than the first curvature, the mouthpiece altering from the biased state into the flexed state in response to application of force onto opposing ends of the mouthpiece in opposite directions, the mouthpiece altering from the flexed state into the biased state upon cessation of the force.

### Claim 4 (depends on 1)

The oral treatment device according to claim 1 wherein the distal end of the bite platform is devoid of notches and extends continuously in a non-interrupted manner from a first end of the bite platform to a second end of the bite platform.
