Understanding Root Canal Treatments: What to Expect

Overview: Root canal therapy is one of the most misunderstood dental treatments, often wrongly associated with pain or fear. In reality, a root canal can save a failing tooth, relieve pain and prevent the need for extraction. This guide explains what root canal therapy involves, when it’s needed, and what you can expect before, during and after treatment.

The root canal is one of the most misunderstood procedures in dentistry, often unfairly labelled as painful or intimidating. In truth, modern root canal therapy is no more uncomfortable than a standard filling, and it allows your dentist to save a natural tooth that would otherwise need to be extracted.

This guide walks you through the purpose of a root canal, the treatment steps and the recovery process so you know exactly what to expect.

With a clearer understanding of the procedure, you can feel more confident and prepared when your dentist recommends root canal therapy.

What is a root canal?

A root canal is performed to treat an infection inside the tooth. When bacteria enter the inner pulp—usually due to deep decay, cracks or trauma—it can lead to a painful abscess. As the pulp dies, the tooth becomes brittle, discoloured and vulnerable to breaking down.

Root canal therapy removes this infected tissue, cleans the inner canals and seals the tooth to prevent reinfection. A crown is often added to strengthen and protect the tooth, helping you preserve your natural smile for many years.

When do you need a root canal?

Your dentist may recommend a root canal if decay or trauma reaches the tooth’s inner pulp. This is why regular dental checkups are important—they allow early detection and treatment before infection develops.

It’s also possible to require a root canal after unnoticed cracks or chips expose the inner tooth to bacteria. If the tooth cannot be saved, extraction may be recommended, followed by a dental implant, bridge or denture. Extraction is always a last resort, making early intervention essential.

What happens during root canal therapy?

Root canal procedures are carried out under local anaesthetic, ensuring you remain completely numb throughout. Your dentist will confirm you are comfortable before starting.

To begin, the top of the tooth is opened to access the pulp chamber. Special tools remove the infected tissue from each canal, and the space is flushed to eliminate bacteria. Once fully clean, tiny posts may be placed to strengthen the structure.

The canals are then filled with a putty-like material that hardens in place. Finally, the tooth is restored with a filling or, if needed, a crown to improve strength and appearance.

What is the recovery time following a root canal?

After the procedure, the anaesthetic may take a few hours to wear off, so resting is advised. You should not experience further pain—the infection causing your discomfort has been treated.

The tooth may feel sensitive or “different” for a few days. Avoid chewing on the affected side and steer clear of extreme temperatures until the area settles.
