i have an infection showing on xray under tooth 21 but tooth 22 is causing me agony. they are so close it could be either one b/c i have sever crowding its hard to tell where the pressure is. they both have root canals.20 is missing, 18 and 19 have root canals with filling and need crowns. i am worried that the infection will come back if i retreat the root canals and crown the teeth. i read alot about the toxins and how bacteria is never gone and can't be reached by antibiotics anyways. should i just pull the teeth and have 3 missing teeth where i would get one implant where 21 was and a fixed bridge connecting 18-23? is that safer than keeping around infected teeth? then later on i could possibly afford implants for all the missing teeth?
i am worried the infected teeth should just be removed. i have had terrible times with root canals and 3 crowned teeth have been drilled thru to retreat old root canals.
