Prior to surgery, an apical fistula is found associated with the discolored upper left central incisor (Fig.1 <). Pain has improved reportedly since taking Amoxicillin for #14 implantation 3 weeks earlier. Note that the gingival margin of the affected tooth is higher than that of the right central. How to correct it?
