A device for cleaning teeth, allows the simultaneous cleaning of the teeth of at least one arch. The device includes: a single or a double arc-shaped tray which can enclose the teeth of one arch or both arches at once and which, via the free edge(s) thereof, can be fitted to the corresponding gum or gums, the tray made from a flexible material allows reversible deformation and is compatible with medical use; and fluid-injection/-removal elements for injecting fluid into the tray and removing fluid from the interior thereof. Once the tray is in place on the teeth, the fluid-injection/-removal elements subject them to repeated cycles of fluid injection/removal to clean the teeth by the combined action, within the tray, of fluid circulation over and between the teeth and mechanical action of the tray's internal surface on the teeth, resulting from the deformation of the tray during the injection/removal cycles. |

1. A teeth cleaning device for simultaneously cleaning the teeth of at least one arch, comprising:
a single or double arc-shaped mouth piece, adapted to enclose the teeth of an arch or of both arches at the same time, respectively, and to adapt, by a free edge or edges of the mouth piece, on the corresponding gum or gums, the mouth piece being made of a flexible material accepting a deformation reversible and compatible with a medical use, and a fluid injection/extraction configured for injecting fluid in the mouth piece and extracting the fluid from an inside of the mouth piece, the fluid injection/extraction device subjecting the mouth piece, once the mouth piece is fitted on the teeth for cleaning the teeth, to repeated fluid injection/extraction cycles causing pressurization/depressurization cycles of the mouth piece for cleaning the teeth by a combined action, in the mouth piece, of a fluid circulation on the teeth and between the teeth and a mechanical action of an internal surface of the mouth piece on the teeth, resulting from the relaxation and the constriction of the mouth piece during the injection and extraction cycles, respectively. |
