Discoloration of Upper Canines and 1st Bicuspids

Five months post debanding, the upper right canine becomes transiently symptomatic (tender to touch).  Although both the right (Fig.1) and left (Fig.2) canines (3) and 1st bicuspids (4) discolor, the right ones are necrotic (pulpal test).  It appears that these two teeth have periapical radiolucency (Fig.3,4), while the lateral incisor has shortened root (2).  The longest tooth (upper canine) appears to be the most vulnerable to trauma associated with orthodontic movement.
