Root canal treatment
The inflamed or dead nerve is removed, the canals inside the roots are cleaned, disinfected and sealed under the microscope, and the tooth is kept rather than extracted.

A painful tooth, an abscess or a root filling that has let you down: Angel Ognemirov, MSc Endodontics, treats patients from Burton upon Trent and the surrounding villages with a diagnosis you can rely on, root canal treatment carried out under the microscope and a measured pace that suits even the most reluctant patient.
Tested, explained, treated — and your own tooth still in place.

Call 0116 270 0550 and say your symptoms are urgent — acute pain and swelling are seen as a priority.
Emergency root canal treatmentEndodontic care
Inside every tooth, running down the middle of each root, lies a channel of living tissue: nerve and blood vessels together. When decay, a crack or a knock lets bacteria in, that tissue becomes inflamed, then dies, and the infection moves out of the root into the jaw. The result is the deep, pounding ache most people picture when they hear the words "root canal" — and, if it is left, an abscess.
Endodontics is the branch of dentistry that treats this hidden part of the tooth: root canal treatment, retreatment of root fillings that have failed, endodontic surgery and the care of cracked and injured teeth. Different procedures, one purpose — remove the disease and keep the tooth.
This is the whole of Angel Ognemirov's clinical work. Your own dentist continues to look after the rest of your mouth and restores the tooth afterwards; the inside of the tooth is treated here and returned with a full report.
Treatments and assessments
From a first root canal to the rescue of a tooth treated long ago; from a toothache that nobody can pin down to a swelling that appeared overnight. Every service starts by finding the cause and finishes, wherever it can, with your own tooth still in place.
The inflamed or dead nerve is removed, the canals inside the roots are cleaned, disinfected and sealed under the microscope, and the tooth is kept rather than extracted.
Learn moreA tooth that was root-treated years ago can become infected again. The old filling is removed, the canals that were missed are found and treated, and the tooth is sealed anew.
Learn moreWhen infection lingers at the tip of a root that cannot be reached from inside the tooth, a small surgical procedure under local anaesthetic removes it and seals the root end.
Learn moreThat brief, sharp stab when you bite is usually a crack. Finding it and gauging its depth under magnification decides whether the tooth is protected, root-treated or beyond saving.
Learn moreAccidents chip, loosen and dislodge teeth. Quick action saves a knocked-out tooth, and patient monitoring afterwards catches the nerve damage that can appear months later.

Learn moreThe tooth that hurts is not always the tooth that is wrong. Methodical testing and the right X-rays identify the culprit and what it needs — sometimes nothing more than reassurance.
Learn moreAn abscess is infection that has leaked from a dead tooth into the bone. Antibiotics quieten it for a while; cleaning and sealing the canals is what removes it for good.

The journey
Online in a minute or by telephone. Mention whether you are in pain, whether your dentist has seen the tooth and whether recent X-rays exist.
Your history, an examination, cold and bite tests and the X-rays that are needed. You leave with a written diagnosis, plan and fee — or confirmation that no treatment is required.
Under local anaesthetic, with the tooth isolated, each canal is measured, cleaned, disinfected and sealed under the microscope — usually in one visit.
Your dentist fits the protective crown or filling. Healing is confirmed on a later X-ray and your dentist receives a full report.
Dental phobia and nervous patients
A surprising number of people live with a toothache for months because the treatment frightens them more than the pain does. The fear usually goes back to one bad experience years ago, and "root canal" is the phrase that brings it flooding back. Angel treats phobic and nervous patients on purpose, and regards it as some of the most worthwhile work he does.
You will be told what is going to happen before it happens. The anaesthetic is tested before treatment starts. You agree a signal that stops everything the instant you use it, and the appointment is booked with enough time that nothing is rushed. Because Angel has completed training in oral and intravenous dental sedation at Guy's Hospital in London, sedation can also be discussed at your consultation where it would help.
Say you are nervous when you book. You stay in charge of the appointment from the first minute to the last.

About me
MSc Endodontics, University of Chester
Angel Ognemirov holds an MSc degree in Endodontics from the University of Chester. He has completed training in oral and intravenous dental sedation at Guy's Hospital in London.
Angel focuses on providing high-quality endodontic care, particularly for patients who experience dental anxiety. His patient-centred approach combines modern endodontic techniques with a calm and supportive treatment experience.
He also holds a certificate in Restorative Dentistry and is an active member of the Society for the Advancement of Anaesthesia in Dentistry (SAAD).
Patients come to Angel from Burton upon Trent itself and from Stretton, Branston, Horninglow, Winshill and Stapenhill, as well as Tutbury, Swadlincote, Willington and the villages beyond — referred by their dentist or booking directly.
Precision
A root canal can be narrower than a human hair, bend sharply and divide without warning, and a molar often has one more canal than it appears to. Root fillings fail for particular, avoidable reasons: a canal that was missed, a filling that stops short, a seal that leaks.
Working under an operating microscope answers each of them. Magnification and direct light show the floor of the tooth clearly, so canals are found rather than hunted for; electronic measurement fixes the length of each root; flexible nickel-titanium instruments follow the canal's natural curve; and activated disinfectant reaches the fine branches no instrument can.
No clinician can promise a result, and none will be promised here. What this standard of care does is give your tooth the best realistic chance of healing and lasting.
The equipment serves the judgement. A sound diagnosis and an honest view of the tooth's prospects come first; precision carries out the plan.
Emergency root canal treatment
Toothache that starts on its own, lingers after a hot drink or pulses at night means the nerve is inflamed or has died. Painkillers hold it off for a few hours; they do not cure it, and an infection left alone can spread.
Book and say that your symptoms are urgent. You will be seen as promptly as possible, the pain relieved first and the remaining treatment planned for a time that suits you.
Seek medical help at once if a swelling is spreading quickly, you have difficulty swallowing or breathing, or you feel very unwell: NHS 111 or A&E.
Your own tooth first
A natural tooth is held in a ligament that senses how hard you bite and keeps the bone around it alive. It requires no surgery to install, costs less over a lifetime than any replacement and, once properly treated and restored, can last for decades.
An infected tooth, a failed root filling or a canal that proved difficult for someone else is not, in itself, a reason to lose the tooth. Each case is judged on its merits and you receive a written view of the realistic options and their likely success.
When extraction genuinely is the right course, you will be told so plainly and your dentist helped to plan the replacement. When the tooth can be saved, you will be shown how.
Questions and answers
Short, direct answers. The patient guides go into more depth.
Not when the tooth is properly numbed — and it is tested before anything begins. You feel pressure, vibration and water, not pain; if anything sharp breaks through, more anaesthetic is given straight away. A few days of tenderness afterwards is normal and settles with ordinary painkillers.
Yes. Caring for phobic and nervous patients is a particular interest of Angel's: every step is explained before it happens, the anaesthetic is checked first, you can stop the appointment with a signal and nothing is rushed. He has also completed training in oral and intravenous dental sedation, so sedation can be considered where it would help. See dental phobia and nervous patients.
Usually an hour to ninety minutes, and most teeth are completed in one visit. A heavily infected tooth, a retreatment or unusual anatomy may need a second appointment.
No. Many patients book directly. If your dentist has already seen the tooth, tell us what they found and they will receive a report after your visit. See do I need a referral?
Usually, yes. Your own tooth keeps the ligament and bone around it healthy, needs no surgery to place and generally costs less over a lifetime than an implant or bridge. Replacement is right only when a tooth genuinely cannot be restored — and you will be told honestly if that applies.
Usually: the old root filling is removed, missed or re-infected canals are cleaned and the tooth is sealed again. Where the canal cannot be reached from above, endodontic surgery treats the root tip directly. Only a split root or too little remaining tooth means extraction.
They may calm a swelling for a while, but they cannot reach bacteria sealed inside a dead tooth, so the infection comes back when the course ends. Only treating the canal system removes the cause.
Root canals are narrow, curved and often hidden. Magnification and direct light let every canal be found, cleaned to its full length and sealed — which is what makes the treatment last. A missed canal is the most common reason a root filling fails.
Back teeth almost always do, because a root-treated molar without a crown is prone to cracking. Some front teeth can be restored with a filling. Your own dentist fits it, guided by the report sent after treatment.
It depends on the tooth and how complex the treatment is, so the fee is confirmed in writing after your consultation and before treatment begins. It does not change part-way through.
