Specialist endodontics to save natural teeth

Endodontic treatment (commonly referred to as root canal treatment) is used to save and restore natural teeth that have become internally infected. The pulp tissues within teeth consist of a complex network of nerves and blood vessels that are susceptible to infection if exposed to bacteria and decay.

If specialist intervention is not sought, the condition is likely to progress and result in the tooth being extracted. There is also a risk of infection spreading to nearby teeth and causing additional issues.

Thankfully, effective root canal treatment can save affected teeth in most cases, restoring their appearance and function.

How it works

Root canal treatment FAQs

What causes root canal infection?

Root infection is most typically caused by bacteria entering the internal parts of the tooth and impacting the tissues and nerves that make up the dental pulp. This can be as a result of decay, a leaking filling, or an accident/trauma.

How do I know if I have a root canal infection?

Symptoms can vary, though the most common indications are:

  • Sensitivity to hot and cold foods/drinks
  • Pain when biting and chewing
  • Swollen gums
  • Enamel discolouration
  • Tooth looseness
  • Bad breath
How long should a repaired tooth last?

In the majority of cases, successful root canal treatment can prolong the life of a tooth for approximately 10-15 years. A good oral hygiene regime and regular visits to the clinic for check-ups and hygiene appointments can extend longevity, potentially as long as a lifetime.

Is the treatment painful?

Many people associate the idea of root canal treatment with anxiety and discomfort. Thanks to the latest techniques, however, the reality is far less intimidating.

We use highly effective local anaesthetics for the majority of our root canal treatments to keep discomfort to an absolute minimum. Some mild sensitivity may be experienced after the procedure, though this can be reduced by taking over-the-counter painkillers.

What if I am particularly anxious?

We offer excellent sedation services for patients who are nervous about their procedure. Please discuss the options with one of our team prior to your appointment.

Will the newly restored tooth need special care?

Following treatment, it is important to avoid biting or chewing with the affected tooth until it has been safeguarded against external pressures. This can be achieved through either a durable lab-made restoration or by wearing a protective nightguard.

We highly recommend that all patients maintain proper daily oral hygiene habits, such as flossing and brushing.
