Is it safe to have a root canal performed on an infected tooth?!


Question: tooth #27 was filled 4 months ago. but now needs a root canal. was told this by my dentist. he warned me previously that this root canal may be needed. was put on antibiotics yesterday and am scheduled for the root canal today. the last root canal he performed on me was tooth #30 5 months ago. that one was infected and he performed the root canal. i was under serious pain for the next few day after. could that infection have influenced tooth #27? and maybe other teeth on that side of my mouth?

Infection is the reason dentist do root canals. It is definitely safe and warranted to not only remove the infection, but to expedite the healing process. Unfortunately, pain can be a result of any surgical procedure, and root canals are no different. I doubt that the infection in #30 caused the problem with #27 Good Luck

No dentist is going to do anything until the infection clears. This is common sense.

i dont know about passing on the infection between teeth but that makes sense

either way you are going to hav pain after a rootcanal

mine was not that bad though and i was the first molar from the front on the bottom--- badly broken before the root canal but oddly had never caused pain before

wont the root canal prevent the infection from spreading. Maybe what happened is that the 1st time the doctor thought only the one tooth was infected and once removed everything would be okay but come to find out either the infection had already spread or popped up elsewhere in your mouth.

It is normal to have pain in your mouth for a few days after such a surgery. Just listen to your doctor, let him do his job. He knows what is best.

make sure you get the tooth crowned afterwards. If you don't it will eventually break down and you'll lose the whole thing.

Your first abscessed tooth is not related to your current abscessed tooth.

Antibiotics are prescribed for abscessed teeth to calm the infection prior to treatment. If there is a significant infection, especially one that causes a patient to be in pain, the freezing will not take.

Whether or not ONE night of antibiotics is enough is the question!!! I think it would have been prudent to give it more time, at least two or three days.

If your dentist attempts to freeze and it does not take, you should not pay for the dental visit (and by NO MEANS let him attempt to drill). He should have given you more time for the antibiotics to work.

If the freezing takes, EXCELLENT! No worry!

Probably not related unless you had trauma on that side of your face at some point. A month ago or several years ago. New rules on the length of time to take antibiotics before procedure, if can numb tooth for your comfort and infection not out of hand yet can perform in 24 hrs. Probably deep decay caused this or dentist drilled too far (too close) to pulp chamber. Sometimes fillings will cause this to happen chasing decay.Pain after RCT normal.
