After almost three decades of performing root canal treatments here in Oxford, I’ve noticed one consistent concern among my patients: uncertainty about what actually happens during the procedure.
Let me walk you through exactly what a root canal treatment involves, drawing from my extensive experience of saving many natural teeth.
What is a Root Canal Treatment?
A root canal treatment preserves your natural tooth by removing infected or damaged tissue from inside the tooth structure.
Your tooth contains a soft living tissue called dental pulp, running from the crown through small channels (canals) in the roots.
These canals house your tooth’s blood vessels, nerves, and connective tissues – essential during tooth development but not crucial once your tooth is fully mature.
When bacteria invade these canals through deep decay, cracks, or injury, the resulting infection can cause severe pain and eventually lead to tooth loss if left untreated.
Root canal treatment removes this infected tissue while maintaining your natural tooth’s structure and function.
At our Oxford practice, we’ve achieved success rates exceeding 90%, with many treated teeth lasting a lifetime.
When Do You Need a Root Canal?
Several situations may indicate the need for root canal treatment, and recognising these signs early significantly improves your outcome.
- Deep tooth decay often leads to pulp infection, particularly when cavities have been left untreated for extended periods.
- Cracked teeth from injuries, teeth grinding, or biting hard objects can expose the pulp to bacterial infection.
- Multiple dental procedures on the same tooth may cause cumulative trauma to the pulp, leading to inflammation and eventual death of the tissue.
- Previous large fillings that are very close to the nerve can sometimes cause the pulp to die gradually over time.
Key Signs You May Need Root Canal Treatment
- Severe, throbbing tooth pain that keeps you awake at night often indicates pulp inflammation or infection.
- Sharp pain when biting down on food suggests possible pulp damage or a cracked tooth requiring immediate attention.
- Prolonged sensitivity to hot and cold temperatures, particularly when the sensation lingers after the stimulus is removed, indicates potential pulp problems.
- Swollen, tender gums around a specific tooth, especially with a small pimple-like bump, suggest an abscess requiring urgent treatment.
- Darkening or discolouration of a tooth, particularly after an injury, can signal internal bleeding and pulp death.
- Sometimes, patients experience no symptoms at all, which is why regular dental check-ups are crucial for early detection.
The Root Canal Procedure: A Detailed Guide
Your First Appointment
Your initial visit begins with a thorough examination of the affected tooth.
Modern digital X-rays provide detailed images of your root canal system, showing the number and shape of canals requiring treatment.
These X-rays also reveal the extent of any infection and help identify potential complications, such as curved roots or additional canals.
After diagnosis, we will explain your personalised treatment plan, including the number of appointments needed – typically two to three sessions for most cases.
The Treatment Process
- Local anaesthetic is administered precisely to ensure complete numbness of the treatment area.
- After confirming you’re fully numb, a protective rubber sheet (dental dam) isolates your tooth, creating a clean, dry working environment and preventing any debris from entering your mouth.
- A small opening is created in your tooth’s crown using specialised dental instruments – for back teeth, this is typically on the biting surface, while for front teeth, access is usually made from behind the tooth.
- The length of your root canals is measured precisely using electronic apex locators and X-rays, ensuring thorough cleaning of the entire canal system.
- Specially designed nickel titanium rotary root canal files of increasing sizes thoroughly clean and shape each canal, removing all infected tissue and creating space for the filling material.
- Throughout the procedure, antimicrobial solutions irrigate the canals, eliminating bacteria and dissolving tissue debris.
- Each canal is methodically shaped, cleaned, and disinfected to prevent any chance of reinfection.
- For teeth with significant infection, medicaments may be placed inside the tooth between appointments to ensure complete bacterial elimination.
Completing the Treatment
- Once your canals are thoroughly cleaned and shaped, they’re dried using precise paper points.
- A rubber-like material called gutta-percha, combined with special root canal cement, fills and seals each canal completely.
- The access cavity is then sealed with a permanent filling material to protect your tooth between appointments.
- Your final appointments involve preparing and placing a permanent restoration – usually a crown – especially on back teeth, to protect your treated tooth from fracture.
- Modern ceramic crowns are custom-made to match your natural teeth perfectly in both colour and shape.
Recovery and Aftercare
- Mild discomfort following treatment typically lasts 24-72 hours and responds well to standard painkillers like paracetamol or ibuprofen.
- Your jaw may feel slightly tender from keeping your mouth open during the procedure – warm compresses can help alleviate this discomfort.
- Avoid chewing on the treated tooth until your permanent crown is placed, as root-treated teeth are more susceptible to fracture without full coverage restoration.
- Most patients return to work or normal activities the day after treatment, though you may wish to take the remainder of the treatment day off.
- Continue your normal oral hygiene routine, being gentle around the treated area.
- If you experience severe pain, swelling, or if your bite feels uneven, contact our practice immediately for assessment.
Common Questions About Root Canals – Your Concerns Answered
Q: Will my root canal treatment hurt?
- Modern local anaesthetics ensure you’ll feel no pain during the procedure.
- The treatment actually relieves pain by removing infected tissue – most patients report immediate relief from their pre-treatment toothache.
- Our practice offers additional options for anxious patients, including longer appointments and detailed explanations of each step.
Q: How long does a root canal treatment take?
- Initial appointments typically last 60-90 minutes.
- Most teeth require 2-3 appointments for complete treatment.
- Front teeth with single canals may be completed in one longer appointment.
- Back teeth with multiple canals usually need additional appointments due to their complexity.
Q: What are the current costs for root canal treatment?
Private treatment costs vary depending on the tooth’s location and complexity:
- Front teeth: £495-£695
- Premolars: £550-£850
- Molars: £800-£1,200
These private fees include all appointments needed to complete the root canal treatment but exclude the final crown.
Q: Can I eat normally after a root canal?
- Wait until all numbness has worn off to avoid accidentally biting your cheek or tongue.
- Avoid chewing hard food on the treated tooth until your permanent crown is fitted.
- Stick to softer foods for the first 24-48 hours.
- Avoid very hot or cold foods if your tooth feels sensitive.
Q: What happens if I don’t get a root canal?
- Untreated infections can spread to other parts of your body, potentially becoming serious.
- The tooth will eventually need extraction if left untreated.
- Tooth extraction often leads to more costly treatments like implants or bridges to restore your bite.
- Neighbouring teeth may shift into the gap left by an extracted tooth, causing alignment and cleaning problems.
Q: How long will my treated tooth last?
- Success rates exceed 90% for teeth treated and properly restored with a crown.
- Most root-treated teeth last a lifetime with proper care and regular dental check-ups.
- The longevity of your treated tooth (particularly back teeth) depends largely on having a permanent crown placed promptly.
- Regular dental hygiene appointments help maintain the health of your treated tooth.
Q: Will I need time off work?
- Most patients return to work the day after treatment.
- Schedule appointments in the afternoon if possible, allowing time for numbness to wear off.
- Avoid important meetings or presentations on treatment days.
Preventing Future Root Canal Problems
- Regular dental check-ups every six months allow early detection of potential problems before they become severe.
- Prompt treatment of cavities prevents bacteria from reaching the tooth pulp and causing infection.
- Wearing a properly fitted mouthguard during sports activities protects your teeth from injury-related pulp damage.
- If you grind your teeth at night, a custom-made night guard can prevent cracks that might lead to pulp infection.
- Address any tooth sensitivity or pain promptly – early intervention often prevents the need for root canal treatment.
- Professional cleaning by our dental hygienist helps maintain healthy teeth and gums, reducing infection risk.
