Root canal treatment has a reputation as one of the most dreaded dental procedures. But that reputation is well out of date. For most patients, having a root canal today feels much like having a filling. Here is what really happens, and why there is no need to fear it.
Inside every tooth is a soft core called the pulp, which contains nerves and blood vessels. If decay, a crack or an injury allows bacteria to reach the pulp, it can become inflamed or infected. Root canal treatment removes the infected pulp, cleans and disinfects the inside of the tooth, then seals it to stop infection from returning.
The pain people associate with root canals usually comes from the infection itself, not the treatment. In fact, root canal treatment is designed to relieve pain.
The tooth is fully numbed with local anaesthetic before we start, and we always check you are comfortable before we begin. Most patients feel nothing more than a little pressure. If you do feel anything, just raise your hand, and we will stop.
It is normal for the tooth to feel a bit tender for a few days, especially when biting. This is usually easily managed with over-the-counter pain relief and settles quickly.
Root canal treatment is usually completed in one or two appointments. Afterwards, the tooth often needs a crown to protect it, particularly back teeth, which take a lot of force when chewing.
The alternative to a root canal is usually taking the tooth out. While that might seem simpler, a missing tooth can cause neighbouring teeth to drift, affect your bite and eventually need replacing with a bridge, denture or implant. Keeping your natural tooth is almost always the better option where possible.
On the NHS, root canal treatment is a band 2 treatment, costing £76.60 from April 2026. Privately at Castle Street, root canal treatment starts from £400 for front teeth and from £525 for molars.
