During my childhood, my front tooth (21) got cracked due to a fall. Later, because of an infection, that tooth had to be extracted. Many years later, the adjacent teeth (11 and 22) also became infected. The doctor performed surgery on the upper gums to remove the infection, and after performing Root Canal Treatment (RCT) on teeth 11 and 22, a bridge and crowns were placed to replace the missing tooth (21)."Now after 16 or 17 years ,i have pain on left side by pressing nose but normally there is no pain.Doctor told me for xray and cbct . In arepoer of cbct it's showing that a redicular cyst on left side on tooth root 22 and on tooth 11 there is black area which dont know what it is? It can be either surgery defect or cyst.. but i dont gave oain on right side on tooth 11 . Doctor suggested to do surgery on front upper side abd remove the cyst without doing any re -rct on tooth 11&22 .i want 2nd opinion -what to do? surgery or removing tooth 22 will automatically remove cyst within it.
