What Does a Root Canal Do? Complete Guide for London Patients

Tooth pain can be extremely uncomfortable, especially when it affects your ability to eat, sleep, or focus. If you've been told you need a root canal, you may be wondering — what does a root canal actually do?

In this blog, we’ll explain everything you need to know about the root canal procedure, how it helps, what to expect, and why patients in London choose this treatment to save their teeth and relieve pain.

What Does a Root Canal Do?

A root canal is a dental treatment that removes infection from the inside of a tooth. It helps:

Eliminate pain and infection
Save your natural tooth
Prevent the need for extraction

Inside every tooth is soft tissue known as the dental pulp, which contains nerves and blood vessels. If this pulp becomes infected due to decay, cracks, or trauma, it can lead to severe pain, swelling, and abscess formation. A root canal removes this infected pulp, cleans the space, and seals it to prevent further issues.

Signs You Might Need a Root Canal

You may need a root canal if you experience:

Persistent toothache or throbbing pain
Sensitivity to hot or cold that doesn’t go away
Swollen or tender gums near the tooth
A dark or discoloured tooth
A pimple-like bump on the gums (abscess)

If you are in London and notice any of these symptoms, it's important to consult a dentist or endodontist right away. Delaying treatment could result in the need for an extraction.

What Does the Root Canal Procedure Involve?

Let’s break down what happens during a root canal:

1. Examination and Diagnosis

Your dentist will take X-rays to examine the condition of your tooth and check for signs of infection. If the infection is confirmed, they will recommend root canal treatment. Many dental clinics in London offer advanced diagnostic tools for accurate assessment.

2. Anaesthesia and Access

Local anaesthesia is used to numb the tooth and surrounding area, so the procedure is virtually pain-free. A small opening is made in the top of the tooth to access the infected pulp.

3. Cleaning the Canals

Special instruments are used to remove the infected or damaged pulp tissue. The root canals are then cleaned, shaped, and disinfected to remove any remaining bacteria.

4. Filling the Canals

Once cleaned, the canals are filled with a rubber-like material called gutta-percha to seal the space. This step helps prevent reinfection.

5. Restoration

The tooth is sealed with a temporary or permanent filling. In many cases, a dental crown is recommended afterward to strengthen and protect the tooth, especially if it’s a back molar.

Does a Root Canal Hurt?

A common myth is that root canal treatments are painful. In truth, modern root canal therapy is very comfortable and often compared to getting a regular filling. The treatment is done under local anaesthetic, and most patients feel relief from pain right after the procedure.

In London, dental specialists use advanced techniques and equipment to ensure a smooth and gentle experience.

How Long Does It Take?

Simple root canals can be done in a single visit (60–90 minutes).
More complex cases may require 2–3 appointments.

Your dentist will let you know how many visits you’ll need based on the condition of your tooth.

What Happens After the Procedure?

After your root canal:

You may feel mild sensitivity for a few days, which is normal.
Over-the-counter pain relief usually helps.
Follow-up with your dentist for a permanent filling or crown.

With good oral hygiene and regular check-ups, a root canal-treated tooth can last a lifetime.

Why Choose a Root Canal Over Extraction?

A root canal allows you to:

Keep your natural tooth
Maintain your natural smile
Avoid costly tooth replacements
Chew and bite properly

Tooth extraction may seem like a quick fix, but it can lead to gaps, shifting teeth, and the need for bridges or implants.

Choosing the Right Specialist in London

If you're in London, it's important to visit a dentist or endo specialist (endodontist) who has experience performing root canals. Specialist practices offer:

Advanced imaging (like CBCT scans)
Dental microscopes for precision
Pain-free techniques and sedation options
High success rates, even in complex cases

Whether you're a local resident or referred by your general dentist, a London-based endodontist can provide expert care.

Final Thoughts

So, what does a root canal do? It removes the infection, relieves pain, and saves your tooth — all without the need for extraction. The procedure is safe, effective, and widely used to restore dental health.

If you’re in London and experiencing tooth pain, don’t wait. Early treatment with a root canal can save your natural tooth and protect your long-term oral health.
