Root Canal Treatment
What is root canal treatment?
Root canal treatment is a tooth-saving procedure used when the pulp — the living tissue and nerve inside a tooth — becomes inflamed or infected.
This can happen as a result of deep decay, significant trauma or a crack that has allowed bacteria to reach the inner part of the tooth. Without treatment, infection can progress and may eventually result in severe pain or a dental abscess.
The aim of root canal treatment is to remove the infected or damaged tissue, clean and disinfect the inside of the tooth, and then seal it to help prevent further infection.

Signs you may need root canal treatment
Recognising the warning signs can help you seek treatment before an infection becomes more serious.
Symptoms can include:
- Severe or persistent toothache – particularly pain that continues or becomes worse when biting or chewing.
- Prolonged sensitivity – especially to hot or cold drinks and foods, where the sensitivity continues after the temperature stimulus has gone.
- Swelling or tenderness – particularly in the gum around the affected tooth.
- Tooth discolouration – a tooth may become noticeably darker than the teeth around it.
- A dental abscess – this can appear as a small, pimple-like swelling on the gum and may sometimes release fluid.
Not every painful tooth requires root canal treatment, so an examination is essential to establish the cause of your symptoms.
What can I expect during root canal treatment?
The procedure is carried out under local anaesthetic to keep you comfortable.
Your dentist will carefully remove the damaged or infected pulp, clean and disinfect the internal root canal system, and then fill and seal the canals. The tooth will subsequently be restored with an appropriate filling or, where necessary, a crown to provide additional protection.
The number of appointments required varies depending on the tooth involved, the complexity of its root canal system and the extent of the infection.
Does root canal treatment hurt?
Root canal treatment has a reputation for being uncomfortable, but modern dentistry has changed considerably.
With effective local anaesthesia and careful techniques, most patients are comfortable during the procedure. In fact, root canal treatment is often undertaken specifically to relieve the pain caused by an infected or inflamed tooth.
If you are nervous about treatment, please let us know. We can take additional time to explain each stage and ensure you remain as comfortable and relaxed as possible.
What happens after root canal treatment?
It is normal for a root-filled tooth and the surrounding area to feel slightly tender for a short period following treatment.
Over-the-counter pain relief such as paracetamol or ibuprofen may help manage any temporary discomfort, provided these medicines are suitable for you.
If pain, swelling or other symptoms persist or worsen, contact the practice so that we can assess you.
What is the alternative to root canal treatment?
If a tooth cannot be successfully treated with root canal therapy, or if root canal treatment is not appropriate, extraction may be necessary.
A missing tooth can subsequently be replaced using options such as a dental implant, bridge or denture. Wherever possible and appropriate, however, our preference is to preserve your natural tooth.
Why is a crown often recommended after root canal treatment?
A tooth that has undergone root canal treatment can be more susceptible to fracture because of the amount of tooth structure that may have been lost through decay, existing restorations and the treatment itself.
For this reason, a crown is often recommended where additional protection is required, particularly for back teeth, which are exposed to significant chewing forces.
Your dentist will assess the remaining tooth structure and recommend the most appropriate restoration for your individual situation.
