If you’ve ever been told you might need a root canal, it’s natural to feel a little nervous. But in reality, this common procedure is one of the best ways to relieve pain and save your natural tooth from extraction.
So, what is a root canal treatment? In short, it’s a dental procedure designed to remove infection from the inside of a tooth, clean and disinfect the area, and then seal it to prevent further damage. This treatment not only eliminates discomfort but also helps preserve your natural tooth for years to come.
At Walnut Dental Clinic, our experienced dentists in Milton Keynes carry out root canal treatments with precision and care, ensuring every patient feels comfortable, informed, and confident throughout the process.
What Is A Root Canal Treatment? Your Questions Answered
A root canal treatment is designed to remove infected or inflamed pulp from inside a tooth, helping to relieve pain and save the natural structure whenever possible. If you’ve ever wondered what is a root canal treatment and why it’s needed, it’s a procedure that carefully cleans, disinfects, fills and seals the inside of the tooth to prevent reinfection.
Rather than removing the tooth, a root canal removes the infected tissue, cleans the inside of the tooth, and seals it, helping you keep your natural smile intact.
At our dental clinic in Milton Keynes, we use gentle techniques and modern equipment to make root canal treatment as comfortable and efficient as possible.

What Is A Root Canal?
A root canal is a restorative dental procedure that removes infected or damaged pulp from the inside of a tooth. The pulp can become infected due to deep decay, cracks, repeated dental work, or trauma.
During the procedure, your dentist will:
- Numb the area using a local anaesthetic.
- Create a small opening in the tooth to reach the pulp chamber.
- Remove the infected tissue.
- Clean and disinfect the inside of the tooth.
- Fill and seal it to prevent reinfection.
Once the infection is cleared, the tooth is restored with either a filling or a crown to strengthen and protect it.
For a simple overview of the medical process, you can also visit the NHS guide to root canal treatment.
Extract Tooth vs Root Canal
When a tooth becomes infected, there are often two treatment options: root canal therapy or tooth extraction.
Root Canal Treatment
A root canal allows you to keep your natural tooth by removing only the infected inner tissue. The outer structure remains intact, which helps maintain your bite, appearance, and overall oral health.
Advantages of root canal treatment:
- Saves your natural tooth and maintains normal chewing function.
- Prevents nearby teeth from shifting.
- Often, a quicker recovery compared to extraction.
- Long-term solution when done properly.
Disadvantages of root canal treatment:
- May require longer appointments.
- Slightly higher cost.
- Complex root structures may require specialist care.
Tooth Extraction
Extraction removes the entire tooth, including its root. It’s sometimes necessary if a tooth is too damaged to be restored.
Advantages of extraction:
- Simpler and quicker procedure.
- Lower upfront cost.
Disadvantages of extraction:
- Leaves a gap, which can affect your bite and appearance.
- Neighbouring teeth may shift into the empty space over time.
- May require a dental implant or bridge later to restore function.
At Walnut Dental Clinic, our goal is always to preserve your natural teeth wherever possible. Your dentist will assess your tooth carefully and discuss which option offers the best outcome for your oral health and comfort.
Is a Root Canal Painful?
A root canal has an outdated reputation for being painful, but thanks to modern dentistry, that’s no longer the case. Today, root canal treatment is virtually pain-free and actually provides relief from the severe pain caused by an infected tooth.
During the procedure:
- A local anaesthetic completely numbs the area, so you won’t feel pain.
- You may feel some gentle pressure or vibration, but this is normal.
-
The source of pain/the infected nerve is removed during treatment.
After the procedure:
- Some mild tenderness or sensitivity is normal for a few days.
- Over-the-counter pain medication is usually all that’s needed.
- If you experience persistent discomfort, your dentist can help.
If you’d like further reassurance, the Oral Health Foundation’s root canal advice offers additional guidance and tips for recovery.
How Long Does a Root Canal Take?
A root canal appointment usually takes between 60 and 90 minutes, depending on the tooth and the complexity of the case.
Factors that affect treatment time include:
- Type of tooth: Front teeth (with a single root) are simpler and quicker; molars can take longer.
- Extent of infection: A severe infection may require two visits to ensure complete healing.
- Previous dental work: Older fillings or crowns can make treatment more intricate.
Typical schedule:
- Single visit: Suitable for straightforward cases.
- Two or more visits: Used for complex or heavily infected teeth, allowing medication to work between appointments.
At Walnut Dental Clinic, we always allow plenty of time for treatment so you never feel rushed. Our dentists ensure you’re comfortable, relaxed, and informed at every step.

Root Canal Treatment Side Effects
After your root canal treatment, it’s completely normal to experience a few mild side effects as the area heals. Most resolve quickly, but it’s useful to know what to expect.
Common side effects:
- Mild pain, swelling, or sensitivity for a few days.
- Numbness for several hours after anaesthetic.
- Slight tenderness when biting.
Less common side effects:
- Reinfection: If bacteria remain, the infection could return (rare).
- Nerve irritation: Temporary numbness or tingling in rare cases.
- Tooth discolouration: The treated tooth may darken slightly.
- Tooth brittleness: The tooth can become weaker without a crown.
- Sinus issues: For upper molars, there may be temporary sinus pressure.
When to contact your dentist:
If you experience persistent pain, swelling, or a bad taste in your mouth, book a review appointment. Our team will check that healing is progressing as expected and provide additional care if needed.

Tooth Root Canal Process
A root canal is typically carried out over one or two appointments, depending on how severe the infection is. Here’s a step-by-step overview of what happens:
First Appointment
- Anaesthetic: The area around the tooth is numbed for a pain-free experience.
- Dental Dam: A small rubber sheet keeps the tooth clean and isolated.
- Access Opening: The dentist makes a tiny hole in the crown of the tooth.
- Pulp Removal: The infected or dead pulp tissue is carefully removed.
- Cleaning and Shaping: The canals are disinfected and shaped using fine tools.
- Temporary Seal: A temporary filling is placed to protect the tooth between visits.
Second Appointment
- Check for Infection: The dentist ensures the infection has fully cleared.
- Permanent Filling: The canals are filled with a rubber-like material called gutta-percha and sealed with dental cement.
- Restoration: The opening is closed with a filling, and a crown may be fitted later to strengthen the tooth.
At Walnut Dental Clinic, our focus is on patient comfort. We take the time to explain each step, ensuring you remain relaxed and confident throughout your visit.
How to Avoid a Root Canal
Prevention is always the best treatment. With good oral hygiene and regular dental care, you can significantly reduce your chances of ever needing a root canal.
Practice Good Oral Hygiene
- Brush your teeth twice a day for at least two minutes with fluoride toothpaste.
- Floss or use interdental brushes daily to remove plaque between teeth.
- Use a fluoride mouthwash for extra protection against decay.
Maintain a Healthy Diet and Lifestyle
- Limit sugary and acidic foods and drinks.
- Avoid chewing on hard objects, such as ice or pens.
- Don’t smoke, as it increases your risk of gum disease and tooth decay.
See Your Dentist Regularly
- Attend regular check-ups and hygiene appointments.
- Treat small cavities or cracks early before they reach the pulp.
- If you experience pain or sensitivity, book an appointment promptly.
Protect Your Teeth
- Wear a mouthguard during contact sports.
- Avoid using your teeth to open bottles or packaging.
