How much is root canal retreatment in London?

Root canal retreatment at Sure Smile Clinic London starts from £550 depending on the tooth and number of canals. A replacement crown is quoted separately.

Is retreatment more painful than the first root canal?

No. It is done under local anaesthetic and most patients report it feeling much the same, with mild tenderness for a few days afterwards.

How successful is root canal retreatment?

Around 75–85 per cent of retreated teeth heal well. Success depends on the cause of failure and whether the tooth can be sealed properly afterwards.

Do I need a new crown afterwards?

Usually yes. Back teeth in particular need cuspal coverage to prevent fracture once the root filling is complete.

What if retreatment is not possible?

Then we consider root-end surgery or extraction with a bridge or implant. We will explain the pros, cons and costs of each.

Root Canal Retreatment at Sure Smile Clinic, London

Why root canals fail

An extra canal was never found and cleaned
The filling material has shrunk or leaked over time
New decay has undermined the crown seal
A crack in the root allows bacteria back in
The permanent restoration was delayed too long

What retreatment involves

We remove the crown or filling, take out the old root filling material, then negotiate, clean and shape every canal with rotary instruments and irrigants. A rubber dam keeps the tooth isolated. The canals are re-sealed and the tooth restored, usually with a new crown.

Success rates and alternatives

Retreatment succeeds in roughly 75–85 per cent of cases. Where a root is fractured or the tooth is too broken down to restore, extraction and an implant may be the better long-term investment — we will tell you honestly which we would choose.
