Is Anesthesia Ineffective On Infected Roots?

hello.,its my 1st post here. Anyway, i am undergoing RCT on my left molar. The dentist says she cannot use anaesthesia because "the roots" are infected. But when she inserts a file, it hurts like hell. Is it true that anaesthesia won't work if "the roots" are already infected?

Hi. Welcome to Healthcaremagic. I read your query. Its true that anaesthesia works less in case of infection due to acidic pH created by pus. But it is not mandatory that it does not work at all. If the infection is too much, you can first take a course of antibiotics prescribed from your dentist to bring down the infection.
Then you can get the tooth anesthetize for RCT.
As you mentioned its painful on insertion of file during RCT, these means you have some vital pulp remaining in that tooth. Without anesthesia, the procedure would be painful and time consuming.
Do warm saline rinses for draining out infection.
Hope the answer helps you. Thank you!
