Effective root canal treatment is essential for preserving an infected tooth and avoiding an extraction. At Mint Dental Clinic, our team is particularly interested in Endodontics, which uses cutting-edge technology, knowledge and experience to ensure your comfort and a successful outcome.

To do this, we use microscope technology that provides magnification and fibre optic illumination during treatment. The microscope lets our endodontist view tiny details within your tooth for more precise treatment. We also uses rotary files for even more accuracy, so you spend less time in the dental chair.

Why might I need a re-root canal?

You might need to have your root canal redone for several reasons. Sometimes, the initial treatment does not heal properly. Other causes include:

  • New damage or decay exposes the root canal filling.
  • The crown protecting the tooth cracks or becomes loose.
  • The previously treated tooth has broken.
  • The first root canal was not completed to a sufficient standard to prevent contamination in the tooth.
  • The shape of the root canal is more complicated but was not detected during the initial endodontic assessment.
  • Crown fitting was delayed following the previous treatment.

What are signs there might be a problem with my existing root canal?

Some common symptoms of a complex root canal that may require a re-root canal treatment include:

  • Pain when biting down
  • Tenderness
  • Swelling
  • A blister or bump inside your mouth

What can I expect when having a re-root canal treatment?

Before the procedure, your dentist will carefully examine your tooth to determine why your first root canal might have failed. This assessment will enable the dentist to create a treatment plan for your re-root canal treatment.

Your dentist will follow the same procedure as before. Sometimes, if the root canal is narrow or blocked, you may require a minor surgical procedure. The surgery involves making a small cut in the gum under a local anaesthetic.

The dentist will remove any diseased tissue and the root’s tip before sealing the root canal’s end and closing the incision.

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.

Over the past six years Dr Raj and Preanka and all of the team at Mint have been exceptional. Every member of the team is exemplary at their expertise and I've never felt in better hands at the dentist. Affordable and top of the range, I would recommend them to anyone.
