An alignment device for a bitewing radiograph includes a longitudinally extending handle having a first end and a second end and a tip disposed at the second end and extending orthogonally to the handle, wherein a length of the tip is substantially less than a length of the handle and wherein a cross-sectional area of the tip is substantially less than a cross-sectional area of the handle. This alignment device enables a dentist or other x-ray operator to easily and quickly align a bitewing radiograph so as to obtain a diagnostic non-overlapping x-ray of crooked teeth in a patient's mouth. The alignment device may optionally include a slidable rubber ring or a slidable hub with rod. The ring and hub are dimensioned to slide over the handle to facilitate the lining up of the x-ray cone.
