Apparatus for prevention of snoring and improved breathing

A kit for constructing a dental device comprising:

• a first arch configured to engage at least some of the teeth of a user's first dental arch and having a midline that aligns substantially with the anterior midline of the user's mouth when the first arch is inserted in the user's mouth;
• a dental attachment configured to engage the first arch along the midline of the first arch, the dental attachment comprising an anchoring element configured to be outside the user's mouth when the first arch is inserted in the user's mouth;
• a second arch configured to engage at least some of the teeth of the user's second dental arch having a midline that aligns substantially with the anterior midline of the user's mouth when the second arch is inserted in the user's mouth;
• and
• a flexible tension element comprising a substantially planar surface extending along the longitudinal axis of the flexible tension element, the flexible tension element configured to couple to the second arch proximate to the midline of the second arch, the flexible tension element configured to couple to the anchoring element outside the user's mouth when the second arch is inserted in the user's mouth such that when coupled to the anchoring element, the flexible tension element extends through the anchoring element in a substantially anterior-posterior direction.
