Claim:
1. A dual sided dental instrument for use in intraoral photography comprising: a planar main body having a first side adapted to provide a reflective side and an opposing second side adapted to provide a non-reflective side; said planar main body constructed of a material imparting flexibility at or near a transverse center axis, said transverse center axis dividing said planar main body into a first end portion sized to simultaneously retract both cheeks when inserted into a person's mouth, thereby maintaining said person's mouth in an open position and a second end portion sized to simultaneously retract both cheeks when inserted into a person's mouth, thereby maintaining said person's mouth in an open position; said first end portion having a geometrical shape or outline that is the same as a geometrical shape or outline of said second end portion, said first side having a first reflective surface at said first end portion, a second reflective surface at said second end portion, and a non-reflective surface separating said first reflective surface and said second reflective surface; said opposing second side having a non-reflective surface; said first end portion having a first vertical side edge arranged in a parallel orientation relative to said transverse center axis and comprising a first pair of opposing curved surfaces separated by a first protuberance; said second end portion having a second vertical side edge arranged in a parallel orientation relative to said transverse center axis and comprising a second pair of opposing curved surfaces separated by a second protuberance; and each of said first and second end portions having a pair of longitudinal side edges having inwardly directed surfaces which form arcuate indentations at or about said transverse center axis.
