Abstract: The invention relates to a device for cleaning and/or care of teeth and/or gums, said device comprising a molded spoon-shaped mouthpiece for an upper jaw and/or a lower jaw, provided with at least one channel ending in at least one nozzle for applying liquid to teeth and/or gums. The aim of the invention is to improve one such device for cleaning and/or care of teeth and/or gums, both in terms of the handling thereof and the obtainable cleaning and/or care effect on the teeth and/or gums, in such a way that effective and long-lasting cleaning and/or care of teeth and/or gums can be carried out in a more simple and comfortable manner, especially for people in need of care and confined to bed. To this end, the mouthpiece also comprises at least one channel ending in at least one opening, through which liquid applied to the teeth and/or gums can be essentially sucked out.
