Mouth exercising device

A mouth exercising device defining a first direction and a second direction along a first axis, a third direction and a fourth direction along a second axis orthogonal to the first axis, and a fifth direction and a sixth direction along a third axis orthogonal to the first axis and the second axis, the mouth exercising device comprising:

• an outer body comprising a first body and a second body arranged along the second axis;
• and
• an inner body extending between a first surface of the first body that faces the fourth direction and a first surface of the second body that faces the third direction,
• wherein the mouth exercising device has a first configuration that is an uncompressed state and a second configuration that is a compressed state,
• wherein, in the first configuration, a first outer surface of the inner body in the fifth direction and a second outer surface of the inner body in the sixth direction do not contact the first surface of the first body or the first surface of the second body, and
• wherein, in the second configuration, at least a portion of the first outer surface of the inner body contacts the first surface of the first body and the first surface of the second body, and at least a portion of the second outer surface of the inner body contacts the first surface of the first body and the first surface of the second body.
