Hemisection is a surgical procedure used to save a multi rooted tooth by removing one of its roots. We assess the suitability of this treatment and the expected recovery time during your consultation.
Dr Neha Patel, specialist in endodontics (GDC No. 150517), provides this specialist care at our Primrose Hill practice.

You may be facing a complex infection or a fracture that makes you fear losing a tooth. It is a stressful position to be in. We use 3D CBCT imaging and non-invasive sensibility tests to identify the precise cause of your pain, which lets us judge whether extraction can be avoided. If you are seeing endodontics in London, our diagnostic approach helps us build a targeted plan to stop the infection spreading. Dr Patel uses these tools for an accurate diagnosis before any treatment begins.
We provide a range of endodontic treatments for these issues, including root canal retreatment, apicoectomy, and care for dental trauma. Using an operating microscope, we can precisely diagnose cracked tooth syndrome or incomplete fractures, which cuts the need for exploratory treatment and helps protect your remaining natural structure.
Choosing the right way to save a multi-rooted tooth needs a precise diagnosis. Our specialist-led planning process means you do not undergo the wrong procedure. Dr Patel assesses the root anatomy to decide whether a hemisection is the most viable way to keep your natural tooth.
If the root canal is too complex, we may suggest intentional replantation for inaccessible canal treatment. Other cases may need a retrograde filling for apical sealing or perforation repair for iatrogenic openings. We provide a transparent, diagnosis-first consultation to explain the costs and timescales before you begin treatment.

Saving a natural tooth is often the priority when a multi-rooted tooth is too damaged for a standard root canal. We use this method to remove one infected root while keeping the rest of the tooth intact, avoiding the need for extraction. If you are unsure which root canal treatments: which option fits your case, an endodontist can decide if this is the right path.
It is common to feel anxious about dental work, or unhappy about the state of a tooth. We provide a supportive environment to address these concerns. Dr Patel assesses each case to see whether the remaining tooth structure is strong enough to support the treatment, and your clinical assessment sets out your candidacy and the expected timeline.
We begin by assessing whether your tooth is a candidate for this procedure. This clinical review determines whether the tooth can be saved by removing only one root. If the inflammation is persistent, we may discuss an apicoectomy to address the root tip.
We remove the diseased root while leaving the healthy one intact, keeping the natural tooth in your jaw. We use local anaesthetic for patients who feel anxious.
Once the damaged root is gone, we clean and seal the remaining canal, removing infected nerve tissue to prevent further decay. It is a protective measure that stabilises the tooth.
We smooth the remaining root surface for a proper fit with the final restoration. This reduces the risk of future complications, so the tooth can handle the pressure of biting.
We place a crown over the tooth to protect it and restore its function. This final step strengthens the remaining structure, and treatment is completed over a few visits to allow for proper healing.
We use operating microscopes, precision instruments, and advanced materials for filling and canal disinfection, and the same magnification supports a precise diagnosis of tooth fractures, letting us perform microsurgery that preserves the natural tooth and restores oral health.
We use bioactive materials to stimulate dentine bridge formation, which supports pulp healing. The practice is led by Dr Ope Sodeinde, GDC-registered specialist periodontist (GDC No. 104071).
Whether you need root canal retreatment, apicoectomy, or cracked tooth treatment, we focus on clear communication throughout. We also provide dental trauma care and luxation treatment.
We focus on the outcome of your treatment, with a calm, unhurried environment and honest options presented without pressure, so you understand the clinical reality of your tooth before we begin.
Anxiety is a common concern for those needing root canal work. We keep the experience as comfortable as possible, and the clinician controls the pace. Whether you are worried about the procedure or the fees, we address these details at your initial visit.
A consultation with Dr Patel means we can assess whether this specific preservation method suits your anatomy, and set out the next steps based on your clinical needs.
Fees are set at your clinical assessment. We assess the complexity of the tooth and the supporting bone to provide an accurate quote.
The duration depends on the specific clinical needs of the tooth. We confirm the exact timeframe at your initial consultation.
Putting off treatment is completely normal. We use local anaesthesia for patients who feel anxious.
The longevity of the result depends on the health of the remaining root and your ongoing oral hygiene. We assess the long-term viability of the tooth at your appointment.
Whether a tooth is saveable through this method depends on the specific health of the root structure. We determine suitability at a clinical examination. You can learn what happens at your root canal consultation and how to book to find out if this is the right option for you.
Dr Patel assesses each case to confirm the remaining tooth structure can support the restoration. If you would like to see our full range of endodontics in London, our hub gives a complete overview of root preservation.

We assess your specific clinical needs at a consultation to determine the most effective way to save a tooth. Depending on the complexity of the infection or the anatomy of the root, you may need retrograde filling for apical sealing to close the root end. Where a canal is blocked or cannot be reached, we can perform intentional replantation for inaccessible canal treatment. We also provide perforation repair for iatrogenic openings to seal accidental holes in the root wall.
