An unbalanced tongue-pressing occluder used in oral cavity includes a tongue depressing member, a first occluded member, and a second occluded member. The tongue depressing member resists against a tongue. The first occluded member and the second occluded member are connected with the tongue depressing member and occluded by a left teeth row and a right teeth row, respectively. The thickness of the first occluded member is different from the thickness of the second occluded member. Due to the thickness of the first occluded member differing from the thickness of the second occluded member, a height difference exists between the left teeth row and the right teeth row, such that the myofascia passing through the whole body produces a potential difference to cause a microcurrent variation, so as to alleviate the myofascial pain.
