Root canal treatment
Infected or dying nerve tissue is removed from inside the tooth, the root canals are cleaned and disinfected under the microscope and the tooth is sealed — ending the pain and keeping the tooth.

Endodontic treatment in Corby
Treating the inside of the tooth so the outside can stay
Every tooth has a hollow centre running down through its roots, filled with nerve and blood vessels. When decay, a crack or a knock lets bacteria in, the pulp becomes inflamed and then dies — producing the deep, pulsing ache that most people associate with the words "root canal" and, left alone, an abscess in the jaw.
Endodontics is the branch of dentistry devoted to that hidden space: root canal treatment, the retreatment of root fillings that have failed, root-end surgery and the care of cracked and injured teeth. Whatever the procedure, the goal is the same — take the disease out of the tooth and leave the tooth in your mouth.
This is the whole of Angel Ognemirov's clinical work. You remain a patient of your own dentist, who looks after your routine care and restores the tooth afterwards; the inside of the tooth is treated here and returned with a full report.
Treatments and assessments
Root canal treatment and endodontic care for Corby
From the first root canal to the rescue of a tooth treated years ago, from a toothache nobody can place to a swelling that arrived overnight: each service begins with finding the cause and ends, wherever it can, with a tooth you keep.
Root canal retreatment
When a tooth that was root-treated before becomes infected again, the old filling is taken out, the canals that were missed or re-infected are treated and the tooth is resealed.
Read moreRoot-end surgery
A short surgical procedure (apicectomy) that clears infection from the tip of the root and seals it from below, used when the canal cannot be treated through the crown of the tooth.
Read moreCracked tooth syndrome
Fleeting, sharp pain on biting is the hallmark of a crack. Locating it and judging its depth under magnification decides whether the tooth is protected, root-treated or removed.
Read moreTooth injuries and trauma
Chipped, loosened, displaced or knocked-out teeth need quick action and patient monitoring, because the nerve inside a damaged tooth can fail silently long after the injury.
Read moreCare for anxious patients
Root canal treatment for people who dread the dentist: a clinician trained in dental sedation, anaesthetic that is checked first, a signal that halts everything and appointments that run at your speed.
Read moreToothache diagnosis
A painful tooth is not always the one that hurts. Careful testing and the right X-rays identify the real culprit and what it needs — and rule out root canal treatment where it is not required.
Read moreDental abscess treatment
An abscess is infection that has escaped from a dead tooth into the bone. Antibiotics only suppress it; cleaning and sealing the canals removes its source so the bone can recover.
Read moreWhy patients choose Angel
Careful by default, honest by principle
- Tests, then a diagnosis
- Cold and bite tests and the right X-rays pin down the responsible tooth before anything is suggested. If you do not need root canal treatment, that is what you will hear.
- Microscope for every tooth
- The operating microscope reveals the narrow, curved and hidden canals that are behind most failed root fillings. It is used on every case, not kept for the difficult ones.
- Designed around anxious patients
- Anaesthetic tested before any instrument is picked up, a signal that stops everything and a clinician with training in oral and intravenous dental sedation.
- A written plan, every time
- Diagnosis, options, realistic outlook and fee are set down after your consultation. You decide at home, with the facts in front of you.
- Appointments with room in them
- Enough time is booked to finish properly. Most root canal treatments are completed in a single visit of 60 to 90 minutes.
- Your dentist stays in the loop
- You keep your own dentist for check-ups and the final restoration. They receive a report and X-rays so that nothing falls through the gap.
How it works
Four steps from first contact to a tooth you can bite on
Book
Online in a minute or by telephone. Say whether you are in pain, whether your dentist has seen the tooth and whether recent X-rays exist.
Consultation
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.
Treatment
Under local anaesthetic, with the tooth isolated, every canal is measured, cleaned, disinfected and sealed under the microscope — usually in one visit.
Restore and review
Your dentist fits the protective crown or filling. Healing is checked on a later X-ray and your dentist receives a full report.
Care for anxious patients
If fear has kept you away, you are the patient this was designed for
Plenty of people live with a toothache for months because the cure frightens them more than the pain. The fear usually dates from a bad experience long ago, and "root canal" is the phrase that revives it. Angel treats anxious patients deliberately and regards it as some of the most rewarding 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 halts everything the instant you use it, and the appointment is booked with enough time that nothing is hurried. Because Angel has completed training in oral and intravenous dental sedation at Guy's Hospital in London, sedation can be discussed at your consultation where it would help.
Say you are nervous when you book. You will stay in charge of the appointment from beginning to end.

Precision
Why the microscope is not optional
A root canal may be finer than a hair, curve sharply and divide without warning, and a molar often carries one more canal than first appears. Root fillings fail for specific 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 guarantee a result and you will not be promised one. What this standard of care does is give your tooth the best realistic chance of healing and lasting.
The equipment serves the judgement. Diagnosis and an honest view of the tooth's prospects come first; precision carries out the plan.
Emergency endodontist
Pain that wakes you is a message, not a nuisance
Toothache that starts on its own, lingers after a hot drink or pulses at night means the nerve is inflamed or has died. Painkillers mask it for a few hours; they do not cure it, and an infection that is ignored 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.
Get medical help immediately if a swelling is spreading quickly, you have difficulty swallowing or breathing, or you feel very unwell: NHS 111 or A&E.
Keeping natural teeth
Think twice before a tooth comes out
Your own tooth is held by a ligament that senses how hard you bite and keeps the bone around it alive. It needs 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, by itself, a reason to lose the tooth. Every case is weighed on its merits and you receive a written view of the realistic options and their likely success.
When extraction truly is the right answer, you will be told plainly and your dentist helped to plan the replacement. When the tooth can be kept, you will be shown how.
Common questions
What patients in Corby ask before root canal treatment
Direct answers to the questions that come up most. The patient guides go further.
Will it hurt?
Not with the tooth properly numbed — and it is tested before anything starts. You will feel pressure, vibration and water, not pain; if anything sharp breaks through, more anaesthetic is given at once. A few days of tenderness afterwards is normal.
I am very anxious. Can you really help?
Yes. Caring for anxious patients is a particular interest of Angel's: every step is explained in advance, 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 care for anxious patients.
How long is the appointment?
Usually 60 to 90 minutes, and most teeth are finished in one visit. A heavily infected tooth, a retreatment or unusual anatomy may need a second appointment.
Do I need a referral?
No. Many patients book directly. If your dentist has already looked at the tooth, tell us what they found and they will receive a report after your visit.
Why save a tooth rather than replace it?
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 is the case.
My tooth has already had a root canal. What are my options?
Usually retreatment: 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, root-end surgery treats the root tip directly. Only a split root or too little remaining tooth means extraction.
Won't antibiotics clear the infection?
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.
Why is a microscope used?
Root canals are narrow, curved and often hidden. Magnification and direct light allow every canal to be found, cleaned to its full length and sealed — which is what makes the treatment last.
Will I need a crown?
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.
What does it cost?
It depends on the tooth and the complexity of the work, so the fee is confirmed in writing after your consultation and before treatment begins. It does not change part-way through.
Which areas do you cover?
Patients come from Corby, Kettering, Wellingborough, Oundle, Market Harborough, Stamford, Northampton and the villages between — and from further afield. You do not need to live locally.
How do I book?
Use the "Book an Appointment" button to book online, or telephone 0116 270 0550. Mention whether you are in pain, whether your dentist has seen the tooth and whether recent X-rays exist. The contact page has everything else.
