A root canal is a dental procedure designed to save a severely damaged or infected tooth. Understanding the steps involved can help alleviate anxiety and prepare you for the treatment. This guide will walk you through the root canal process, from initial consultation to final restoration, with a focus on procedures in the UK.
Pre-procedure Consultation and Assessment
Before your root canal treatment begins, you'll have a consultation with your dentist or endodontist. This crucial step involves:
- A thorough examination of the affected tooth
- X-rays to assess the extent of damage and root canal anatomy
- Discussion of your medical history and current medications
- Explanation of the treatment plan and obtaining your informed consent
Your dentist will also discuss NHS and private treatment options, as root canal therapy is typically covered under NHS Band 2 treatment.
Preparation for the Root Canal Treatment
Once you've decided to proceed with the root canal, you'll receive instructions to prepare for the procedure:
- Eat a light meal before the appointment, as local anaesthesia will be used
- Wear comfortable clothing
- Arrange for transportation home if sedation will be used
- Continue taking regular medications unless advised otherwise
The Root Canal Procedure: Step-by-Step
Step 1: Anaesthesia Administration
Your comfort is a top priority. The dentist will:
- Apply a numbing gel to your gum
- Inject local anaesthesia around the affected tooth
- Ensure you're completely numb before proceeding
In some cases, sedation options may be discussed for patients with dental anxiety.
Step 2: Dental Dam Placement
A dental dam is a small rubber sheet that isolates the tooth being treated. It serves several purposes:
- Keeps the area dry and free from saliva
- Prevents debris from entering your mouth
- Improves the dentist's visibility
Step 3: Access Opening Creation
To reach the pulp chamber, your dentist will:
- Create a small opening in the crown of your tooth using a dental drill
- Remove any decay or damaged tooth structure
- Locate the root canal entrances
Step 4: Removing Infected Pulp
This critical step involves:
- Using specialised instruments to remove the infected pulp tissue
- Carefully cleaning out each root canal
- Ensuring all infected material is removed to prevent reinfection
Step 5: Cleaning and Shaping the Root Canals
Once the pulp is removed, the dentist will:
- Use root canal files to shape the canals for filling
- Irrigate the canals with antimicrobial solutions to disinfect them
- Measure the length of the canals to ensure complete cleaning
Step 6: Filling the Root Canals
After thorough cleaning, the canals are filled:
- A rubber-like material called gutta-percha is used to fill the canals
- A sealer paste is applied to ensure a complete seal
- The filling prevents reinfection and seals the root canal system
Step 7: Temporary Filling Placement
To protect the tooth until the permanent restoration:
- A temporary filling is placed to seal the access opening
- This filling prevents contamination of the root canals
- You'll need to be careful with the tooth until the permanent restoration is placed
Step 8: Permanent Restoration
The final step in the process:
- Usually involves placing a crown or permanent filling
- May be done in a separate appointment
- Restores the tooth's function and protects it from future damage
Post-procedure Care and Recovery
After your root canal treatment:
- Take over-the-counter pain relievers as needed
- Avoid chewing on the treated tooth until it's fully restored
- Continue your regular oral hygiene routine, being gentle around the treated area
- Follow any specific instructions provided by your dentist
Potential Complications and Follow-up
While root canal treatments have a high success rate, it's important to be aware of potential complications:
- Mild pain or sensitivity for a few days is normal
- Severe pain or swelling may indicate a problem - contact your dentist immediately
- Attend all follow-up appointments to ensure proper healing
Root Canal Treatment Success Rates
Root canal treatments are highly successful:
- Success rates of 85-97% are reported in UK studies
- Proper aftercare and restoration significantly impact long-term success
- Most root canal treated teeth can last a lifetime with good oral hygiene

Let's address some common misconceptions:
Myth: Root canals are extremely painful
Fact: Modern techniques and anaesthesia make root canals no more uncomfortable than a typical filling.
Myth: It's better to extract the tooth
Fact: Saving your natural tooth through root canal treatment is often the best option for your oral health.
