Hello,

Welcome to healthcaremagic forum.

Usually fistula develops due to spread of infection from periapical tissues into sinus spaces.

If fistula appears on gums after root canal treatment,this is due to faulty diagnosis regarding teeth to be root canal treated.

An x-ray will help to evaluate fistula through inserting GP cone into interdental tissue spaces .

If necessary,adjacent teeth has to be root canal treated and abscess has to be drained and curetted completely.

Hope this helps.

This fistula has to be tr

Hi

Thanks for writing in.

Fistula may appear on gums if Root Canal Treatment is not proper.
If there is any remaining pulp or improper obturation it may lead to abscess formation which leads to sinus or fistula.
You need to get a x-ray done of same tooth.
Consult your dentist for further treatment plan.
Meanwhile take a course of analgesic-antibiotic.

Take Care

Emaculate root canal dont let fistulas to reappear .It indicates that some amount of infection persisted even after R C T.get to a dentist get an X ray pus culture done followed by Apicoectomy

Hi, it is very much possible. If the caries has been long standing, there is a formation of periapical granuloma around the root of the tooth. It does not subside even after root canal treatment. There is continuous pus formation which drains out though the fistula. After the root canal treatment, since the pus cannot drain through the tooth( the tooth being packed with filling), the pus keeps draining through the fistula. You need to go for an apicectomy in such cases where the root portion with the granuloma is cut off. Please consult an oral surgeon for the same. Take care!
