HELLO AND WELCOME,

Thanks for writing in.

As per the details produced,its not clear that whether the root canal treatment for your teeth has completed,or still left to complete the procedure.

Usually,once the root canal treatment has completed,the pain and swelling will subside.

warm saline and betadine rinse frquently will help you out.
maintain good oral hygiene.
ALSO the root canal has to be checked for whether infected pulp and periapical abscess remains still.
If so root canal treatment has to be repeated.
Meanwhile deep scaling has to be done.

AVOID INTAKE OF heavy solid food on the affected site.
take care.

Hi
Taking flagyl for root canal suggest that you have anaerobic infection. it cant be specified how much time will it take. but it depends on how well your root canal is cleaned by the dentist. if the source of infection , which in your case is the infected tooth is taken care of properly, then your problem will soo be over.

Wishing you speedy recovery

DEAR FRIEND.

Thanks for sharing your concern.

penicillin along with flagyl (metronidazole) is usually prescribed during root canal treatment,as it takes care of both aerobic and anaerobic infections very well.this is very much required in cases of root canal treatment.

In your case, if you are not finding comfortable using this combination then you can visit your dentist and another set of antibiotics can be prescribed for you,like augumentin or cephalosporins etc.

Need not worry, you will be fine once your root canal treatment is completed. you will be problem free.

There are no nerves left in the tooth, to cause you pain after root canal,so relax,it will get over.

Meanwhile,if you wish, you can visit your dentist regarding the discomfort faced by with the present set of drugs and ask for a newer combination.

Also do frequent warm saline rinses and maintain very good oral hygiene.this will help you in reducing oral infection.

hope it helps .take care.thanks
