When yourroot canal still hurts,we’ll fix it.
Bring your X-rays and reports. A specialist finds out why it went wrong, tells you honestly what can be saved, and puts it right.
You are not being difficult. You just want it done right this time.
In short
Dental re-treatment means finding out why earlier dental work has failed and putting it right: repeating a root canal (re-RCT), fixing back or remaking a crown or bridge, treating a problem around an implant, or relining a loose denture. At Smile Gallery Dental Wellness Centre in Arera Colony, Bhopal, MDS prosthodontists check the tooth with digital X-rays first, then give you the plan and the cost in writing before anything starts.

What you might be feeling
When a treatment has not worked, coming back to a dental chair takes courage. These are the fears we hear most, and what we do about each one.
We do not repeat what was done before. We find out why it failed first, with digital X-rays and a scan, and plan around the cause, not just the pain.
The treatment itself is painless with good numbing, and we go at your pace. Raise your hand and we pause. You stay in control.
Often a tooth can still be saved. If it truly cannot, we tell you honestly, and show you the best way to replace it.
You get the plan and the cost in writing before anything starts, with what each option means for the years ahead. Nothing is done without your yes.
No blame and no lecture. You did the right thing by asking. Our only job is to fix it.
Ask every question you have. See your own X-ray, take the written plan home, and decide with your family. Coming for an opinion commits you to nothing.
We’ll fix it.
When to get it checked
Problems can show up weeks after treatment, or years later. These are all worth a check.
Sometimes there is no pain at all and the problem shows only on an X-ray. If something doesn’t feel right, a check-up with a digital X-ray gives you a clear answer.
If you have been chewing on one side for months, or living on painkillers, you do not have to any more.
Putting it right
It depends on what we find. You hear every option, and why, before anything starts.
The old filling inside the tooth is taken out, the canals are cleaned again, including any that were missed, and then sealed. It often takes more than one sitting, and the tooth usually needs a crown afterwards to protect it.
About root canal treatmentIf the tooth underneath is sound, the same crown can often be fixed back. If not, we treat the tooth first and make a new crown or bridge that fits properly, measured with an intraoral scanner.
What decides the cost of a crownA loose crown or screw on top can usually be tightened or replaced. Gum infection around an implant is cleaned and treated. If an implant has truly failed, it is removed and a new one is placed once the area heals, with our visiting oral surgeon when surgery is needed.
About dental implantsA loose denture can often be relined so it grips your gums again. If it is old or worn, we make a new one, or talk you through implants that hold a denture firmly in place.
About denturesWe tell you honestly, and show you the best way to replace it: an implant, a bridge or a denture. You get the plan and the cost in writing, and you decide.
Compare your options
When a root canal fails, there are usually three paths. Saving your own tooth comes first whenever it is healthy enough.
| Repeat root canal (re-RCT) | Extraction + implant | Extraction + bridge | |
|---|---|---|---|
| Keeps your own tooth | Yes | No | No |
| Surgery needed | No | Yes, to place the implant | No |
| Teeth next to it | Not touched | Not touched | Shaped to hold the bridge |
| Usual time to finish | A few sittings, then a crown | A few months, while the implant heals into the bone | A few sittings |
| Best when | The root and the bone around it are healthy enough to save | The tooth can’t be saved and there is enough bone | The tooth can’t be saved and the teeth beside it need crowns anyway |
Which is right depends on your tooth. We show you the X-ray, explain each option in plain words, and you decide.

“When a treatment hasn’t worked, people come in tired of hoping. I start by finding out exactly why, and I show them on the X-ray. Once you can see the cause, the right fix is usually clear, and you can decide with confidence.”
Prosthodontists specialise in repairing and replacing teeth: crowns, bridges, dentures and implants. That is exactly the work most re-treatment needs.

I was so concerned & didn’t want to get the tooth removed. I’m so happy by the treatment done by Dr Saurabh! … the way he did the root canal work was absolutely pain free.

Dental treatments can be intimidating, especially when you’ve had a long history with them, but Dr Saurabh was incredibly gentle, patient, and attentive to my comfort.

Pain that stays or comes back, pain when you bite, swelling or a small pimple on the gum near the tooth, a bad taste, or the tooth turning dark. Sometimes there is no pain at all and the problem shows only on an X-ray, so a check with a digital X-ray gives a clear answer.
Mild soreness for a few days after a root canal sitting is common, and it usually settles with the medicine the dentist suggests. Pain that gets worse, lasts beyond a week or two, or comes with swelling is not normal and should be checked, even if the treatment was finished.
Yes, often. A repeat root canal, called re-RCT or retreatment, removes the old filling inside the tooth, cleans the canals again, including any that were missed, and seals them. Whether it can save your tooth depends on what the X-ray shows, and we tell you that honestly first.
In a widely cited review of 17 studies, about three in four re-treated root canals healed completely on X-ray (Ng and colleagues, International Endodontic Journal, 2008). Your own chances depend on the tooth, the cause of the failure and the bone around the root, which we check before advising you.
A root canal can fail years later if new decay reaches the root filling, an old crown or filling leaks and lets bacteria in, the tooth cracks, or a canal was left untreated. That is why a crown over the tooth and regular check-ups matter after a root canal.
If the root and the bone around it are healthy enough, saving your own tooth with a repeat root canal usually comes first: there is no surgery and nothing is removed. If the tooth cannot be saved, an implant or a bridge replaces it. We show you the X-ray and explain each option.
It depends on the tooth, how much needs to be redone, and whether you need a new crown. After the check-up and X-ray, we give you the plan and the exact cost in writing before anything starts, so there are no surprises. EMI is available on implants.
Keep the crown safe, avoid chewing on that side, and come in soon. A dark tooth under a crown often means decay, or a tooth that had a root canal earlier. We check it with an X-ray, treat the tooth if needed, then fix the crown back or make a new one that fits.
Often, yes. First we check whether only the crown or screw on top is loose, which is a simple fix. If the implant itself has failed, it is removed, the area is allowed to heal, and a new implant can usually be placed later. Our visiting oral surgeon joins when surgery is needed.
Usually, yes. Gums and bone change shape over the years, so a denture that once fitted well can become loose. It can often be relined to fit again. If it is old or worn, a new denture, or one held in place by implants, will feel much firmer.
Yes. You can come only for an opinion. We examine the tooth, explain what we find and what your options are, and give you the plan and the cost in writing. You take it home and decide. Starting treatment is always your choice.
Yes. Send your old X-rays and reports on WhatsApp to +91 92007 00750 before your visit, so the doctor can see your history. The full answer comes after we examine the tooth, because an X-ray alone does not show everything.

Aapke sawal, Hinglish mein
RCT ke baad do-teen din halka dard ya sensitivity normal hai, aur doctor ki batayi dawai se theek ho jaata hai. Agar dard badhta jaye, ek-do hafte se zyada rahe, ya sujan aa jaye, to daant ka X-ray karwa kar check karwana zaroori hai. Hum digital X-ray se wajah dhoondte hain.
Ghabraiye nahi. Kai baar root canal dobara (re-RCT) karke daant bachaya ja sakta hai. Pehle X-ray se wajah dekhte hain, phir aapko saaf bataate hain ki daant bach sakta hai ya nahi, aur plan aur kharcha likhit mein dete hain.
Cap ko sambhal kar rakhiye, us taraf se mat chabaiye aur jaldi dikhaiye. Agar neeche ka daant theek hai to wahi cap dobara lag sakta hai. Nahi to pehle daant ka ilaj karke naya cap banaya jaata hai.
