The treatment

What is root canal treatment?

Inside every tooth is a soft centre called the pulp, which contains the nerve and blood supply. When this becomes infected or inflamed, through deep decay, a crack or injury, it can cause pain and, if left untreated, lead to an abscess and the loss of the tooth.

Root canal treatment, also known as endodontics, carefully removes the infected pulp, cleans and disinfects the inside of the tooth, and seals it to prevent further infection. It relieves pain and allows you to keep your natural tooth, which is almost always the best outcome for your long-term dental health.

Signs you may need root canal treatment

Some teeth give clear warning signs, while others cause little pain and are found at a check-up. Common symptoms include:

Persistent toothache

Ongoing or throbbing pain in a tooth, which may be worse at night or keep you awake.

Pain when biting

Discomfort when you chew or press on a particular tooth.

Lingering sensitivity

Sensitivity to hot or cold that continues long after the food or drink has gone.

Swelling or tenderness

Swelling or tenderness of the gum near the tooth, or on the face.

A darkening tooth

A tooth that has become noticeably darker than those around it.

A gum abscess

A recurring pimple or abscess on the gum, sometimes with an unpleasant taste.

Why root canal treatment

The benefits of saving your tooth

Relieves pain

Treatment removes the source of infection, settling the pain and letting the tooth feel comfortable again.

Keeps your natural tooth

Nothing works quite like your own tooth. Saving it avoids the need for an extraction and a replacement.

Protects your other teeth

Keeping the tooth maintains your bite and stops neighbouring teeth drifting into the gap.

Stops infection spreading

Cleaning and sealing the tooth prevents the infection progressing to an abscess.

A lasting result

With a good restoration and care, a root-treated tooth can last for many years.

Often more affordable

Saving a tooth is frequently more straightforward and cost-effective than extracting and replacing it.

What to expect

Your treatment, step by step

Assessment & diagnosis

Dr Varma examines the tooth and takes any X-rays needed to confirm the diagnosis and plan your treatment.

Gentle numbing

The tooth and surrounding area are fully numbed with local anaesthetic, so you stay comfortable throughout. Modern root canal treatment feels much like having a filling.

Removing the infection

The infected or inflamed pulp is carefully removed, and the inside of the tooth is cleaned and shaped.

Cleaning & sealing

The canals are disinfected and then filled and sealed to prevent any further infection. Some teeth are treated in a single visit, others over two.

Restoring the tooth

A filling or, for back teeth, a crown is placed to protect the tooth and restore its strength and appearance.

Review

We check that the tooth has settled and healed well, and advise on keeping it healthy for the long term.

After your treatment

What to expect afterwards

How you may feel

It is normal for the tooth to feel a little tender for a few days as it settles, and this is usually well managed with ordinary pain relief. The relief from the original pain is often felt straight away.

Try to avoid chewing hard on the tooth until it has been permanently restored.

Looking after the tooth

  • Brush twice a day and clean between your teeth.
  • Keep up regular check-ups and hygienist visits.
  • Have the recommended filling or crown placed to protect the tooth.
  • Back teeth usually benefit from a crown for long-term strength.
  • Contact us if pain or swelling returns.

TreatmentFee
Root Canal Treatment (incisor, canine or premolar)£750

Common questions

Root canal FAQs

Does root canal treatment hurt?

Modern root canal treatment is carried out under local anaesthetic, so it should feel much like having a filling. For many patients it actually relieves the pain they arrived with. Dr Varma is known for his calm, gentle approach, especially with nervous patients.

How many appointments will I need?

Many root canals are completed in one or two visits, depending on the tooth and the infection. Dr Varma will explain what your treatment involves after assessing the tooth.

Will I need a crown afterwards?

Often, yes, particularly for back teeth. A root-treated tooth can become more brittle, and a crown protects it and restores its strength. Your dentist will advise whether a filling or a crown is best for your tooth.

Is it better to have a root canal or an extraction?

Keeping your natural tooth is almost always the best option where possible. It maintains your bite and avoids the need to replace the tooth with an implant, bridge or denture. Dr Varma will talk you through your options honestly.

How long will the tooth last?

With a good restoration and regular care, a root-treated tooth can last for many years, often for life. Keeping up your check-ups and hygienist visits helps it last.

What is a re-root treatment?

Occasionally a tooth that has had root canal treatment before can become re-infected. Retreatment involves reopening the tooth, removing the old filling material and cleaning the canals again. It is more complex than a first-time treatment, so an additional fee applies depending on the case.
