Save your tooth.
Relieve the pain.
When decay or damage reaches the nerve inside a tooth, root canal treatment removes the infection and saves the tooth; often in a single visit to our Islington clinic.
The tooth stays.
The infection goes.
Root canal treatment — or endodontic treatment — is carried out when the pulp inside a tooth becomes infected or inflamed due to deep decay, a crack, or repeated dental work. Left untreated, the infection spreads, causes significant pain, and ultimately leads to tooth loss.
The procedure removes the infected pulp, cleans and shapes the root canals, and seals the tooth — eliminating the infection and keeping the tooth functional. It is far more comfortable than its reputation suggests, and modern techniques mean most patients are surprised by how straightforward it is.
Signs you may need root canal treatment
- Persistent or severe toothache
- Sensitivity to heat or cold that lingers after the stimulus is removed
- Pain when biting or applying pressure
- Swelling or tenderness in the gum near the tooth
- Darkening of the tooth
- A recurring pimple or abscess on the gum
What to expect at your appointment
Root canal treatment is straightforward and carried out entirely under local anaesthetic — you will not feel pain during the procedure.
Assessment & X-ray
We examine the tooth, take digital X-rays to assess the extent of the infection and the root canal anatomy, and confirm the diagnosis before any treatment begins.
Local Anaesthetic
The area is numbed fully before we begin. We wait until you are completely comfortable — you should feel pressure but no pain throughout the procedure.
Cleaning & Shaping
The infected pulp is carefully removed, and each root canal is cleaned, shaped and disinfected. The canals are then filled and sealed to prevent reinfection.
Restoration
A root-treated tooth often needs a crown to protect and restore it to full function. We will discuss the best option for restoring the tooth at your appointment.
