Root Canal Treatment in Croydon

Root canal treatment removes infected or inflamed tissue from inside a tooth so the tooth can be kept rather than taken out. We provide NHS and private root canal treatment at our dentist in Croydon on Lower Addiscombe Road, under local anaesthetic.

Why root canal treatment is needed

Inside every tooth is the pulp, a soft tissue containing nerves and blood vessels that runs down through narrow channels in the roots. Deep decay, a crack, a large filling or an injury can let bacteria reach the pulp. It may become inflamed and then die, and infection can spread to the bone at the tip of the root, sometimes forming an abscess.

Once the pulp is badly inflamed or infected it does not heal by itself. The two main options are root canal treatment, which aims to save the tooth, or taking the tooth out. Antibiotics alone do not cure an infected tooth, although they are sometimes used alongside treatment when infection is spreading.

Signs you may need a root canal

Lingering pain

Sensitivity to hot or cold that lasts for a while after the trigger has gone, or throbbing pain that keeps you awake.

Pain on biting

A tooth that feels tender or “high” when you chew or tap it.

Swelling or a gum boil

A swelling or a small spot on the gum near the tooth, sometimes with a bad taste. If facial swelling affects breathing or swallowing, call 999 or go to A&E.

A darkening tooth

A tooth that has turned grey after an injury, which can mean the pulp has died. Sometimes there are no symptoms and it is spotted on an X-ray.

If you are in pain, book an emergency appointment (£65). We will find the cause and relieve the pain, then plan the rest of your treatment.

What happens during treatment

  1. Assessment
    We examine the tooth and take digital X-rays to see the roots and any infection, check whether the tooth is restorable, and explain the options and cost.
  2. Numbing and isolation
    The tooth is numbed with local anaesthetic. A thin rubber sheet (dental dam) is usually placed to keep the tooth clean and dry.
  3. Cleaning the canals
    A small opening is made in the top of the tooth. The pulp is removed and the canals are cleaned, shaped and disinfected with fine instruments.
  4. Dressing
    If more than one visit is needed, a medicated dressing and temporary filling are placed to settle the tooth in between.
  5. Filling the canals
    The canals are sealed with a rubber-like material, and the tooth is restored with a filling.
  6. Protecting the tooth
    Back teeth often need a crown afterwards because root-filled teeth can become brittle and crack.

Each appointment typically takes around an hour to an hour and a half, depending on the tooth. Front teeth usually have one root; back teeth can have three or four, which takes longer.

Comfort, recovery and success

Because the tooth is numbed, treatment usually feels much like having a filling, though appointments are longer. If you are anxious, let us know when you book; our nervous patients page explains how we can help. We do not offer sedation at the practice.

It is common for the tooth to feel tender for a few days afterwards, especially when biting. Over-the-counter pain relief suitable for you usually helps. Avoid chewing hard food on the tooth until it has been fully restored.

Root canal treatment often succeeds, but not always. Very curved or blocked canals, cracks in the root and re-infection can affect the outcome, and some teeth need re-treatment, surgery at the root tip or extraction later. Complications are uncommon but include a broken instrument in a canal or a small perforation of the root. Where a tooth is particularly complex, we may discuss referral elsewhere. We explain the outlook for your tooth before you decide.

The alternative: extraction

Taking the tooth out is quicker and cheaper at the time, and sometimes it is the most sensible choice, for example if the tooth is cracked through or cannot be restored. However, losing a tooth can affect chewing, appearance and how neighbouring teeth sit, and replacing it with an implant, bridge or denture involves its own time and cost. Read more about tooth extraction.

Aftercare and when to call us

Keep the treated tooth clean with twice-daily brushing and daily cleaning between teeth. If a crown has been recommended, try not to delay it, as an unprotected root-filled back tooth is more likely to fracture. Keep up regular check-ups so we can monitor healing on X-rays.

Call us on 020 8656 6959 if pain gets worse rather than better after a few days, swelling develops, the temporary filling falls out, or your bite feels uneven.

Root canal prices in Croydon

Treatment Price
NHS root canal treatment (Band 2, eligible NHS patients) £76.60
Private root canal treatment Priced by tooth after assessment

Private crown (if needed afterwards) From £495

The NHS Band 2 charge covers the whole course of treatment, including fillings and extractions needed in that course; if a crown is needed it falls under Band 3 (£332.10). Private prices vary because back teeth with more roots take longer, and your dentist confirms the cost in writing first. NHS availability varies, so call to check NHS availability.

Spreading the cost: for selected private treatments you can apply for finance through Tabeo, including 0% interest for up to 12 months. Finance is subject to status, and we will explain the options before you commit. See our full price list for other treatments.

Root canal treatment: common questions

How much is root canal treatment in Croydon?

For eligible NHS patients, root canal treatment is part of a Band 2 course of treatment, currently £76.60. Private root canal treatment is priced by tooth after assessment, because teeth with more roots take longer. You get a written quote first.

Is root canal treatment painful?

The tooth is numbed with local anaesthetic, so for most people it feels similar to having a filling. The tooth may be tender for a few days afterwards.

How many appointments will I need?

Usually one or two, each lasting around an hour to an hour and a half. Back teeth may then need a separate visit for a crown.

Do I need a crown after a root canal?

Back teeth often do, as root-filled teeth can become brittle. Front teeth can sometimes be restored with a filling. Your dentist will advise for your tooth.

Can antibiotics fix the infection instead?

No. Antibiotics may help control spreading infection, but they do not remove the cause inside the tooth. The tooth needs root canal treatment or extraction.

What if the treatment does not work?

Some teeth need re-treatment, surgery at the root tip, or extraction. We explain the likely outlook for your tooth before treatment and discuss next steps if problems arise.
