Root canals save teeth

  • Save pulp that’s been damaged by an infection
  • Stop pain when eating or biting down
  • Protect teeth from heightened sensitivity

During a check-up, it’s our chance to examine the teeth, mouth and gums and determine if any underlying conditions impact your smile.

If you’re a new patient to our practice, you’ll need to book in for a comprehensive new patient exam charged at £95 – which includes two x-rays. If you’re an existing patient, you can book a Continuing Care Exam, charged at £50.

Re-root canals

Have you had a root canal before but still in severe pain? It might have failed. Read about re-roots. More.

Are root canals essential?

The root canals are small channels at the base of a tooth that contains nerves, connective tissues, and blood vessels, collectively known as dental pulp.

If a tooth becomes cracked or decayed, bacteria can penetrate the tooth’s surface and infect the pulp. If a tooth’s pulp becomes infected or is at risk of infection, your dentist may need to remove it and replace it with a filling, known as a root canal treatment.

In some cases, depending on how decayed the tooth is, the dentist may also need to fit a crown to your tooth following the endodontic treatment.

Root canal signs and symptoms

An infected tooth can become significantly inflamed. Several symptoms indicate you might need endodontic treatment, including:

  • Sensitivity to hot or cold which lingers
  • Pain when chewing
  • Toothache
  • Swelling of the gums
  • Facial swelling

However, sometimes, dental pulp infection can be asymptomatic. In this case, your dentist will usually spot the issue on an x-ray.

The dental pulp becomes infected when bacteria penetrate the centre of a tooth after it becomes compromised because of a large cavity or breakage incurred through injury, among other things.

A few things can lead to a dental infection requiring endodontic treatment.

These include:

  • Untreated tooth decay
  • Decay underneath a filling in a tooth
  • Crack in a tooth
  • Grinding of the teeth
  • Previous deep fillings

What Can Happen If I Don’t Get Endodontic Treatment?

Leaving an infected tooth alone and not receiving proper, timely treatment for it can have potentially serious consequences, including:

  • Spread of the infection
  • Endodontic abscess
  • Bone loss
  • Tooth loss

What Can I Expect When Receiving Endodontic Treatment?

There are four basic steps to endodontic treatment. First, the dentist will remove any infected tissue from the tooth’s centre.

Next, they will shape the root canals, smooth them out, and disinfect them to ensure they have removed all the bacteria from the tooth. Depending on the severity of the infection, it may take more than one round of treatment before the area is spotless and free from bacteria.

They will fill and seal the root canals to make sure no bacteria can re-enter the canals.

Some dentists may wait a week to ensure the infection is gone before sealing your tooth. If your dentist does not complete the procedure on the same day, the hole in your tooth will be covered with a temporary filling to keep food particles and other debris out of your freshly cleaned tooth.

To seal the tooth, your dentist will use a compound called gutta-percha — a biocompatible material similar to rubber — to fix it with adhesive cement.

Finally, the dentist may fit a crown to restore the function and appearance of the tooth and protect it from reinfection.

4 years a customer and always professional yet friendly service. Corrected my major issues (fillings/caps) and while they're keen to ensure ongoing 'perfect teeth' they don't hard sell peripheral / optional treatments. Highly recommended

I was looking for somewhere with a personal touch, that I could trust and that’s what I got at Mint. They always remember my name and are so polite. After a year of zoom meetings I really wanted my teeth to be straight and the results completely surpassed my expectations. I now feel comfortable taking photos! The team explained everything clearly (I felt I could ask anything multiple times) appointments were always organised and it was a really easy, worthwhile process. My teeth look like my teeth but are now at their best.

The clinic is a really lovely place to visit - it is extremely clean and all of the staff are very friendly. They were kind and reassuring all the way through my Invisalign treatment - as well as having amazing technology at their disposal. Dr Imran is so accommodating and kept everything simple, addressing any concerns straight away. All in all I would definitely recommend Mint Dental Clinic, a lovely experience all round.
