Treatment that saves an infected tooth by cleaning out the inside of the root and sealing it.

- £295-£650 Typical "from" price (686 practices' published fees)
Root canal treatment removes infected or damaged tissue from inside a tooth. It saves a tooth that would otherwise need to come out. The dentist numbs the tooth with a local anaesthetic first, so for most people it feels much like having a filling.
What root canal treatment costs
Private: the London median published starting price for root canal treatment is £450. Half of all practices start between £295 and £650. Back teeth (molars) usually cost more than front teeth, because they have more root canals. Many people need a crown afterwards, especially on a back tooth, and that costs extra.
NHS: root canal treatment is Band 2 and costs £76.60 for the whole course of treatment. If you also need a crown, the course moves to Band 3, which is £332.10. If an NHS root filling fails within 12 months, the same practice must repair or redo it free, in most cases. For how to find a practice, see our NHS dentists in London page.

What happens
Treatment usually takes 1 or 2 appointments. The dentist removes the infected pulp (the soft tissue inside the tooth), then cleans and shapes the canals. Then they fill and seal the tooth. If there are 2 visits, you have a temporary filling in between.
Some complex cases are referred to an endodontist, a dentist who specialises in root canal treatment. This costs more than treatment by a general dentist.
If you are in pain now, see emergency dentists in London. If your dentist suggests taking the tooth out instead, you may want to compare the cost of replacing it with a dental implant.
