Root canal treatment: what to expect, step by step
Root canal treatment has an undeserved reputation. Here is what really happens – and why it can save your tooth.
Why a tooth needs root canal treatment
Inside every tooth is the pulp – soft tissue containing nerves and blood vessels. Deep decay, a crack or repeated dental work can let bacteria reach the pulp, causing inflammation or infection. Without treatment, the infection can spread to the bone around the root and form an abscess.
Root canal treatment removes the inflamed or infected pulp so the tooth can be kept rather than extracted.
Signs to look out for
Common signs include pain that lingers after hot or cold drinks, a throbbing ache, pain when biting, swelling of the gum, or a small “gum boil”. Some infected teeth cause no symptoms at all and are found on an X-ray, which is one reason regular check-ups matter.
What happens during treatment
The tooth is numbed with local anaesthetic. An opening is made in the top of the tooth, the pulp is removed and the canals are cleaned, disinfected and shaped. They are then filled and sealed. Depending on the tooth and the infection, this may take one visit or more.
For most patients the experience is similar to having a filling – the aim is to relieve pain, not cause it.
After treatment
Some tenderness for a few days is normal. Back teeth in particular are often protected with a crown afterwards, because a root-treated tooth can be more brittle. With a good restoration and regular care, a root-treated tooth can last for many years.
