How much does root canal treatment cost in London?

How long does a root canal take?

Most root canal treatments in London are completed in one or two visits of around 60–90 minutes each. Complex cases — particularly back molars with several canals — may take a little longer.

Is root canal treatment painful?

No. With modern anaesthetics it's typically no more uncomfortable than a routine filling. The pain people remember is usually the toothache that brought them in — which the treatment relieves.

Why do I need a crown afterwards?

A root-treated tooth is structurally weaker. A crown protects it from cracking and gives it the best long-term prognosis.

What's the alternative?

The only alternative to root canal treatment is extraction, followed by a bridge, denture or implant to fill the gap. Saving your natural tooth is almost always the best option.

Why might I need root canal treatment?

The pulp at the centre of a tooth contains nerves and blood vessels. When deep decay, repeated dental work or trauma allows bacteria to reach the pulp, the resulting infection can be extremely painful and, left untreated, can cause an abscess.

Common signs you might need root canal treatment include:

Severe, throbbing toothache — especially at night
Sensitivity to hot and cold that lingers
Pain when biting down
Swelling around the tooth or gum
A darkening of the tooth

What happens during treatment

We numb the tooth fully with local anaesthetic and isolate it with a rubber dam to keep the area clean and dry. Using fine instruments, we remove the infected pulp, gently shape and disinfect the root canals, then fill them with a biocompatible material called gutta-percha. The tooth is sealed and, in most cases, restored with a crown to protect it long-term.

Aftercare and outcomes

Most patients walk out feeling significantly better than they came in. There may be some mild tenderness for a few days, easily controlled with simple painkillers. With proper restoration and good oral hygiene, a root-treated tooth can last a lifetime.
