If you have a lingering toothache, a tooth that has darkened, or a tooth that has had root canal treatment before and is causing trouble again, root canal treatment can often save it. At Orchard House Dental Practice in Beckenham, routine root canal treatment is carried out by our dentists, and more complex cases are seen by Omar Tarmohamed, whose practice is limited to endodontics (root canal treatment).

Omar qualified as a dental surgeon from Newcastle University with Merit. After graduating, he returned to the South East for postgraduate training, gaining experience in both hospital Oral and Maxillofacial Surgery and general dental practice.
He is currently undertaking Specialist Training in Endodontics, including a Master’s in Clinical Dentistry, at King’s College London. Because his practice is limited to endodontics, root canal treatment is all he does. He provides the full range of non-surgical and surgical endodontic treatment, including retreatment of teeth that have had root canal treatment before. GDC number 278049. Meet the rest of the team.

Root canal treatment, also called endodontic treatment, removes infected or inflamed pulp from inside the tooth. The canals are then cleaned, disinfected, filled and sealed. It relieves pain, clears infection and lets you keep your natural tooth.
Sometimes there are no symptoms at all and the problem is found at a check-up.
Omar’s fees include a composite core and a post where needed. We’ll confirm your fee before any treatment starts. See our full fee list.
We welcome referrals from other dental practices for non-surgical and surgical endodontic treatment, including retreatment. To refer a patient, call us on 020 8777 6115 or email [email protected].

Make an EnquiryRoot canal treatment is a dental procedure used to treat infection at the centre of a tooth (the root canal system). It involves the removal of the infected or damaged pulp, cleaning and disinfecting the canal, and then filling and sealing it to protect against further damage.
Modern root canal treatments are typically painless as they are performed under local anaesthesia. Any post-treatment discomfort can usually be managed with over-the-counter pain relief.
A root canal may be needed when the inner part of your tooth (the pulp) becomes inflamed or infected due to decay, cracks, or injury. If left untreated, this can cause ongoing discomfort and may lead to an abscess or tooth loss. At Orchard House Dental Practice, our goal is to save your natural tooth whenever possible. Root canal treatment removes the infection and restores the tooth’s function, allowing you to chew comfortably and maintain a healthy smile.
Routine root canal treatment is carried out by our dentists. More complex cases, such as curved or narrow canals, retreatment and surgical endodontics, are seen by Omar Tarmohamed, whose practice is limited to endodontics. Your dentist will talk you through which is right for your tooth.
Sometimes a tooth that has had root canal treatment becomes infected again, often years later. Retreatment involves removing the old root filling, cleaning the canals again and resealing the tooth. Omar provides retreatment at Orchard House.

Yes, the main goal of this treatment is to preserve your natural tooth. By removing the infected or damaged tissue inside, the tooth can often be restored and continue functioning normally for many years with proper care.
At Orchard House Dental Practice, a root canal treatment usually takes between 60 and 90 minutes, depending on the tooth and the complexity of the case. While we can often complete the procedure in a single visit, some cases may require two appointments to ensure the tooth is thoroughly cleaned and sealed. We will let you know what to expect for your specific treatment so you can plan your visit with ease.
Root canal treatment with our dentists starts from £520. For more complex cases with Omar, a consultation with a CBCT scan is £150, treatment starts from £925 for a front tooth and £1,050 for a back tooth, and retreatment of a previously root-treated tooth starts from £1,075 (front) and £1,200 (back). Surgical cases are quoted individually. We’ll give you a clear fee before any treatment starts.
With modern dentistry, the root canal treatment we provide is generally comfortable. We use a local anaesthetic to numb the area completely, so most of our patients feel little more than mild pressure during the procedure. Our team is focused on making your experience as calm and pain-free as possible. Please let us know if you feel anxious so we can discuss additional ways to help you feel at ease.
Common signs that you may need a root canal include a lingering toothache, sensitivity to hot or cold, discomfort when biting or chewing, or swelling around the gums. Sometimes, there may be no obvious symptoms, and the need is only discovered during a dental examination. At Orchard House Dental Practice, our team uses thorough assessments and modern imaging to identify whether root canal treatment is required, ensuring you receive the right care at the right time.
After your root canal, it’s normal to experience some mild tenderness or sensitivity for a few days, especially when chewing. This can usually be managed with over-the-counter pain relief and will subside fairly quickly. Most of our patients return to their normal routine the same day. Should any discomfort persist or worsen, we encourage you to contact us so we can ensure everything is healing as it should.
It is normal to feel mild tenderness for a short period after treatment, especially when biting. This usually improves within a few days. Your dentist may recommend pain relief if needed and will guide you on how to care for the tooth as it heals.
With proper care and good oral hygiene, a tooth that has had a root canal treatment can last a lifetime. It’s important to follow up with regular dental check-ups and cleanings.
A root canal is recommended when the goal is to save the natural tooth. Keeping your own tooth helps maintain normal biting strength and prevents nearby teeth from shifting, which can happen after an extraction. It is usually the preferred option when the tooth can still be restored.
