According to one aspect of the invention, there is provided an oral debris removal device including: a suction unit; a tube in fluid communication with the suction unit, the tube having a tip portion adapted to allow introduction of oral debris into the tube via the tip portion; and a light source positioned to illuminate the tip portion of the tube and a region adjacent to the tip portion of the tube. The oral debris removal device may further include a debris collector chamber coupled between an end section of the suction unit and an end section of the tube. The debris collector chamber may include an internal protruding element disposed along an air flow path across a space between the end section of the suction unit and the end section of the tube, the internal protruding element adapted to prevent oral debris and liquid exiting the tube from entering the suction unit. |
