Hi Sir/Mam is it a front tooth or molar , in abscess case difficult to assure the life of the teeth , depending on the size of the abscess, you should have attached the X-ray also , would have been more easy to suggest what to do next , re root canal is not successfull unless it is properly done , if it's front teeth I would suggest apisectomy I.e cut the root tip along with abscess, if it's molar I suggest hemisectomy is nothing but removing that perticular teeth which has abscess,saving rest portion of root and teeth , Dr.Venkat VDENTIS DENTAL CARE , HYDERABAD
