What Is Root Canal Treatment?
Root canal treatment, also known as endodontic treatment, removes infection from inside a tooth. Each tooth contains a soft tissue called the pulp, which holds nerves, blood vessels, and connective tissue. When the pulp becomes infected or damaged, treatment is often needed to stop the infection spreading.
During root canal treatment, the infected pulp is removed, the root canals are carefully cleaned and disinfected, and the space is sealed and restored to prevent reinfection, allowing your natural tooth to stay in place.

Signs You May Need Root Canal Treatment

Benefits of Root Canal Treatment
- Preserves your natural tooth
- Aims to remove the source of infection
- May help relieve pain
- May help restore chewing and speaking function
- Prevents the need for extraction in many cases
Is Root Canal Treatment Painful?
This is one of the most common questions patients ask. Modern root canal treatment is designed to relieve pain, not cause it. With contemporary techniques and effective local anaesthesia, most patients find the procedure similar in comfort to receiving a routine filling, and many notice an improvement in discomfort following treatment.
For patients who feel particularly anxious about treatment, sedation options may also be available to help make the appointment more comfortable. Just mention this when you book.
What Happens If Infection Is Left Untreated?
Ignoring a dental infection can lead to more serious complications, including severe pain, abscess formation, swelling, bone loss around the tooth, and in some cases, tooth extraction. Seeking treatment early often allows the tooth to be saved and reduces the risk of complications.
Aftercare Following Root Canal Treatment
After treatment, it’s normal to experience mild sensitivity for a few days. We’ll ask you to follow all aftercare instructions, maintain good oral hygiene, avoid excessive pressure on the treated tooth initially, and attend any follow-up appointments. Most patients return to normal activities shortly after treatment.
