1. A suction device for attachment to a dental prophy angle comprising:
a tubular hood;
said tubular hood having an elongate arced profile extending along a horizontal axis between a front end at the front of the suction device and a rear end at the rear of the suction device of said tubular hood and operable to extend over the upper length of a prophy head of a prophy angle while leaving uncovered beyond the front end of the tubular hood a full circumferential portion of an outer end of the working tip of the prophy head at the front of the prophy angle;
said tubular hood opened at the bottom operable to leave a lower portion of the prophy head uncovered;
a strap;
said strap radially extending from one side of said elongate arc profile to the other side around the horizontal axis and configured to circumferentially secure a prophy head of a prophy angle within the tubular hood and strap while defining a suction intake region between said tubular hood and an upper circumferential portion of the prophy head;
said strap having a length that extends along the horizontal axis a distance that is less than the length of said tubular hood from the front end to the rear end;
a suction tube;
an upward end of said suction tube in communication with said rear end of said hood;
said suction tube descending downward following a vertical axis before terminating at a downward end and configured for positioning adjacent the rear side of a prophy angle neck; and,
wherein said downward end of said suction tube is operable for connection to a suction supply.
