Save Your Natural Tooth with Advanced Root Canal Therapy
At EGO Dental Clinic in Central London, our root canal treatments are delivered with precision, magnification, and exceptional care — helping you preserve your natural teeth and avoid extraction.
Whether you’re dealing with a deep cavity, abscess, or infected tooth pulp, our skilled dental team, including experienced endodontic clinician Dr Thomas, provides predictable, gentle root canal therapy using cutting-edge tools and the latest clinical guidelines (2025 update).

What Is a Root Canal?
A root canal is a dental treatment that removes infection from the inside of a tooth — specifically the pulp, which contains nerves and blood vessels. Once cleaned and sealed, the tooth can be restored with a filling or a crown, allowing you to keep it rather than have it extracted.
It’s a common, highly successful procedure designed to:
- Relieve pain or sensitivity
- Eliminate infection
- Prevent the need for extraction
- Restore tooth function
What Is Re-Root Canal Treatment?
Sometimes, a previously treated tooth becomes reinfected or fails to heal. In such cases, we may recommend a re-root canal, which involves:
- Removing old filling material
- Re-disinfecting the canal system
- Correcting hidden or untreated anatomy
- Sealing and restoring the tooth again
Microscopic re-root canals can offer excellent long-term results, especially when performed early.
Magnification & Microscopic Dentistry
At EGO Dental, we use dental loupes (4.5–6.0x magnification) and high-powered microscopes for complex cases, allowing us to:
- Visualise tiny root canals
- Detect micro-cracks and hidden infections
- Improve cleaning, shaping, and sealing
- Increase success rates significantly
This advanced technology is especially vital during re-root canal procedures, or when dealing with curved, narrow, or multi-rooted teeth.
Root Canal Success Rates (2025 Research)
According to the latest 2025 clinical studies, success rates for root canal treatment are:
- Up to 93% for primary root canals
- 80–85% for re-root canal treatments
- 95%+ when followed by full-coverage crowns (especially on back teeth)
- Lower success when:
- Delayed treatment
- The tooth is cracked
- Inadequate previous work
Note: Root canals are highly effective — but not 100% guaranteed. We will always explain your specific prognosis before starting.
What Investigations Are Needed?

Before a root canal is confirmed, we may perform:
- X-rays or CBCT scans to visualise the tooth roots, bone, and extent of infection
- Vitality tests (cold or electric) to check nerve response
- Crack detection under magnification
- Clinical photographs and bite testing to assess fracture or trauma
If a tooth is found to be cracked, we will advise you on alternative options. Not all cracked teeth are restorable with root canal therapy.

FAQ – Root Canal
What is root canal treatment?
Root canal treatment is a dental procedure used to treat infection or inflammation inside a tooth. The dentist removes the damaged pulp, cleans and disinfects the inside of the tooth, and then seals it to prevent further infection.
Why might I need a root canal?
You may need root canal treatment if the pulp inside your tooth becomes infected due to deep decay, repeated dental procedures, cracks, trauma, or gum disease. Symptoms can include toothache, sensitivity, swelling, or sometimes no symptoms at all.
Is root canal treatment painful?
No. Modern root canal therapy is performed under local anaesthetic. You’ll feel pressure, not pain. We also offer extra numbing for anxious patients.
How long does a root canal treatment take?
Typically 1–2 visits. Some complex molars or re-root canals may require more.
What happens during root canal treatment?
The dentist removes the infected pulp, carefully cleans and shapes the root canals, and fills them with a biocompatible material. The tooth is then sealed, and in many cases restored with a crown to protect it long term.
Will I need a crown after root canal treatment?
Most molars do — a crown protects the tooth from fracture and greatly improves long-term success. Front teeth may not always need crowning.
How long does a root canal-treated tooth last?
With proper care and a suitable restoration, a tooth that has had root canal treatment can last many years or even a lifetime. Good oral hygiene and regular dental check-ups are essential.
What happens if I delay root canal treatment?
Delaying treatment can allow the infection to worsen, potentially leading to severe pain, abscess formation, and the loss of the tooth. Early treatment improves the chances of saving the tooth.
Are there alternatives to root canal treatment?
The main alternative to root canal treatment is tooth extraction. However, saving the natural tooth is usually the preferred option whenever possible, as it maintains normal function and prevents the need for tooth replacement.
What should I expect after root canal treatment?
Some mild tenderness or sensitivity is normal for a few days after treatment. This can usually be managed with over-the-counter pain relief. Your dentist will advise you on aftercare and any follow-up appointments.
Can a root canal fail?
Like all treatments, it carries risks — but with advanced imaging, magnification, and full coverage (crowns), success rates are very high.
Still Have Questions?
We’re here to guide you every step of the way — with no pressure, clear communication, and expert care.
If you’re experiencing pain, sensitivity, or swelling, don’t delay. Early diagnosis improves outcomes — and can save your tooth.
