Root canal retreatment in New Chandigarh
A tooth that has already had a root canal can become painful or infected again, sometimes years later. Retreatment means reopening the tooth, removing the old filling material, cleaning the canals again and sealing them properly. Managing these cases is a core part of endodontic specialist training.
Why an earlier root canal may fail
- A canal was narrow, curved or hidden and was not fully cleaned the first time.
- The crown or filling was delayed, or has leaked, and bacteria re-entered the tooth.
- New decay has formed under an old crown.
- The tooth has cracked.
- A piece of instrument separated inside the canal during earlier treatment.
How it is done
Assessment
X-rays, and a CBCT scan where needed, show the old root filling and any untreated canals.
Reopening the tooth
The tooth is numbed and opened. Old filling material is removed from the canals.
Finding what was missed
The canals are explored, cleaned and disinfected again along their full length.
Resealing
The canals are sealed again. Bioceramic materials are used where they suit the case.
New restoration
The tooth gets a new, well sealed filling or crown so the problem does not return.
Aftercare
- Expect some soreness for a few days, as after a first root canal.
- Healing of the bone around the root is checked with follow up X-rays over the coming months.
- Have the final crown or restoration placed on time. Delay is a common cause of reinfection.
Common questions
My root canal was done years ago. Can it still fail?
Yes. A treated tooth can be reinfected if the seal breaks down, new decay forms, or a canal was left untreated. Pain, swelling or a gum boil near an old root canal should be checked.
Is retreatment always possible?
Not always. It depends on how much sound tooth remains, the shape of the roots and whether there is a crack. Dr. Rathore will tell you honestly if the tooth is worth saving.
A piece of file broke in my tooth. What now?
A separated instrument does not always cause a problem. Depending on its position it can be removed, bypassed or sealed in place. This needs careful assessment on an X-ray.
This page is general information. Whether a treatment suits your tooth can only be decided after an examination.

Best doctor in chandigarh, i got my RCT done for 4 teeth and it was such a pain free experience. I would highly recommend her always there to help no matter the time. Even after weeks without any issue, the support and care remains the same, thank you Dr. Srishti
I got scaling done from Dr. Srishti and she did the entire process with so much patience and care that I was really amazed to see her attention to detail. I even got my young daughter to her for tooth extraction later seeing her professionalism and her tender care given to such a young child. Dr. Srishti made my daughter feel so comfortable and relaxed during the entire process that she didn't panic at all. It is so nice to see such young professionals being so attentive to details especially with children. Thanks Dr. Srishti !!
