ABSTRACT:
A portable apparatus for removing food remains from the oral cavity, particularly from the teeth. The apparatus includes a suction chamber, enclosing a removable filter, a suction member removably fixed to said suction chamber, a pipe in fluid communication with said suction chamber through a casing, and an outer cover of collapsible material removably fixed to said casing. Through depression upon said outer cover and, as a consequence, on said suction member, a depression is created inside the suction chamber, so that, through a pneumatic action, the food remains are moved from the oral cavity into the suction chamber where they are collected on said removable filter.
