A tissue stretching device includes a first and second mouthpiece. Each mouthpiece includes a bite area, an extension bar, and an interface area. The bite area is shaped to match the general curvature of a set of teeth. The interface area has a raised body. The extension bar is positioned between the bite area and the interface area. A connecting assembly is linked to the interface area of the first mouthpiece and the second mouthpiece and arranged to couple the first mouthpiece inline with the second mouthpiece. The second mouthpiece is positioned in an inverted position relative to the first mouthpiece to place the raised body of the first and second mouthpieces in opposing directions. The connecting assembly includes an elongate member. At least one of the first and second mouthpieces is able to be positioned along the elongate member relative to the other mouthpiece.
