Abstract

[Problem] In an oral cavity, the shapes of hard tissue in the teeth tend to change due to contact with each other and mastication; dental abrasion and gaps between teeth often occur, which makes cleaning difficult; and accumulation of food residues in the gaps between teeth due to food/drink intake serves as an energy source for bacteria living in the mouth, thus causing cavities and periodontal diseases. In the case in which a tooth is lost from the jaw, because the tooth on the opposite side is not used on a daily basis, tooth extrusion occurs, the adjacent tooth is moved toward the lost-tooth side, and thus, the masticatory efficiency and periodontal tissue are also adversely affected. The purpose of the present invention is to effectively reduce the occurrence of cavities, staining, or the like, thus protecting teeth; alternatively, the purposes of the present invention include, for example: prevention of improper tooth movement; prevention of food impaction; maintenance of dentition and occlusion; and protection of interdental papilla. [Solution] Teeth are protected by wearing, on a jaw, a meal mouthpiece that comes into close contact with teeth and gums, that is formed of a soft material and a hard material, and in which the outer sides of the occlusion surfaces of molars are formed of the hard material.
