The mouthpiece is a hands free toothbrush designed to fit inside the mouth and clean the teeth, tongue, gums and/or roof of the mouth. The mouthpiece is made up of flexible material and is sized to fit the user's mouth. It contains intricately designed tube structures. It will clean the user's mouth, teeth, tongue and gums. The mouthpiece slips in to the mouth and fits or approximates the contour of an individual's teeth. When not in use, the mouthpiece can be kept in its own container for sanitary purposes. ## Claims ### Claim 1 A dental device for cleaning user's teeth, gums, tongue and roof of the mouth of the user, comprising a mouthpiece shaped to fit or approximate the user's mouth, and to fit in the user's mouth, said device including one or a pore vibratory elements for vibrating portions of the device relative to the user's teeth, and/or gums, and including one or more brushes driven by the one or more vibratory elements, wherein at least some of the brushes are located on an exterior wall of the mouthpiece and extend to clean the gums, tongue and roof of the mouth of the user when the device is in use. ### Claim 2 (depends on 1) The device of claim 1, wherein the one or more vibratory elements comprises one or more ultrasonic transducers. ### Claim 3 (depends on 1) The device of claim 1, wherein the mouthpiece includes one or more tubular structures for delivering or removing a fluid to the user's mouth. ### Claim 4 (depends on 1) The device of claim 1, wherein the mouthpiece further includes an ultraviolet light source. ### Claim 5 (depends on 1) The device of claim 1, wherein the one or more vibratory elements is electrically driven. ### Claim 6 (depends on 5) The device of claim 5, wherein the one or more vibratory elements is battery driven. ### Claim 7 (depends on 1) The device of claim 1, wherein the mouthpiece further includes one or more sensors for measuring at least one physiological parameter of the user's mouth. ### Claim 8 (depends on 7) The device of claim 7, wherein the physiological parameter is selected from the group consisting of a salt component, temperature, moisture, pH, dehydration, blood oxygen level and humidity. ### Claim 9 (depends on 1) The device of claim 1, wherein the mouthpiece is configured to hold a disclosing solution for detecting plaque. ### Claim 10 (depends on 1) The device of claim 1, wherein the mouthpiece further includes a fluid supply for supplying dentifrice or mouthwash. ### Claim 11 (depends on 10) The device of claim 10, wherein the mouthpiece further includes a drainage or suction device for draining excess fluid and saliva. ### Claim 12 (depends on 1) The device of claim 1, where the mouthpiece is custom fitted to the user. ### Claim 13 A dental device comprising a mouthpiece, shaped to fit or approximate the user's mouth, and to fit in the user's mouth, said device including one or more vibratory elements for vibrating portions of the device relative to the user's teeth and/or gums, and including one or more brushes driven by the one or more vibratory elements, wherein at least some of the brushes are located on an exterior wall of the mouthpiece and extend to clean the gums, tongue and roof of: the mouth of the user when the device is in use, and a cleaning device for cleaning and storing the mouthpiece between uses.
