Few phrases in the English language trigger as much immediate anxiety as “you need a root canal.” For many, the words conjure up images of Victorian-era dentistry and significant discomfort. However, the reality of modern endodontic treatment is vastly different from the myths. In fact, a root canal is a pain-relieving procedure, not a pain-causing one.
If you are suffering from a severe toothache, sensitivity to hot and cold, or swelling, your body is signalling that an infection has reached the nerve of your tooth. Ignoring this won’t make it go away; it usually leads to an abscess or, eventually, the loss of the tooth.
At Fitzroy Dental Practice in London, we understand that the unknown is often the scariest part of any medical procedure. By understanding exactly what happens once you sit in the dentist’s chair, you can approach your appointment with confidence rather than fear. This guide walks you through the process, demystifying how this common treatment saves your natural smile.
What Is a Root Canal and Why Do You Need One?
To understand the treatment, you first need to understand the anatomy of your tooth. Beneath the hard white enamel and the dentin lies a soft tissue called the pulp. This pulp contains blood vessels, nerves, and connective tissue.
When a tooth is cracked, has a deep cavity, or has suffered trauma, bacteria can enter the pulp. This causes the tissue to become infected or inflamed. If left untreated, the infection can spread to the bone surrounding the root, potentially leading to a dental abscess and systemic health issues.
Saving the Natural Tooth
The primary goal of a root canal is to save your natural tooth. While extraction is an alternative, keeping your own tooth is always preferable. It maintains your natural bite, ensures efficient chewing, and prevents the surrounding teeth from shifting position.
At Fitzroy Dental Practice, we see patients requiring root canal treatment for several common reasons:
- Deep decay: Cavities that have been left untreated and reached the nerve.
- Repeated dental procedures: Multiple fillings on the same tooth can sometimes stress the pulp.
- Cracks or chips: Even invisible cracks can allow bacteria to enter the inner tooth.
- Trauma: A knock to the face can damage the pulp, even if there are no visible chips.
Understanding the Root Canal Procedure
A root canal is essentially a deep cleaning for the inside of your tooth. At Fitzroy Dental Practice, the procedure is typically completed over two or three visits, depending on the complexity of the infection. Here is the step-by-step process.
Step 1: Assessment and Anaesthetic
Before any work begins, your dentist will take X-rays to assess the shape of your root canals and determine if there are any signs of infection in the surrounding bone.
Once the plan is set, the dentist administers a local anaesthetic to numb the tooth and the surrounding gum. This is the most crucial step for patient comfort. Modern anaesthetics are highly effective, meaning you should feel no pain during the procedure, much like having a standard filling.
Step 2: Access and Cleaning
To keep the area dry and free of saliva, a small sheet of rubber (a dental dam) is placed around the tooth. The dentist then makes a small opening in the crown of the tooth to access the infected pulp.
Using very small, specialised tools, the dentist carefully removes the infected or inflamed pulp. They then clean and shape the inside of the root canals to ensure all bacteria and debris are removed. This part of the process is delicate and requires precision.
Step 3: Shaping and Filling
Once the space is cleaned and shaped, it needs to be filled. If the infection was severe, your dentist might place medication inside the tooth to clear it up and put a temporary filling in place until your next visit.
If the tooth is ready to be permanently sealed, the canals are filled with a biocompatible material (usually a rubber-like material called gutta-percha). This is placed with an adhesive cement to ensure complete sealing of the root canals, preventing bacteria from re-entering.
Step 4: Restoration
A tooth that has undergone root canal treatment can become more brittle over time because the internal blood supply has been removed. To protect the tooth from fracturing and to restore its full function, a dental crown or a large filling is usually required. This final step is vital for the long-term survival of the tooth.
Key Factors Affecting Root Canal Treatment
Patients often have questions regarding the logistics of the procedure. Understanding the time commitment and potential risks helps manage expectations.
How Long Does a Root Canal Take?
Generally, a root canal appointment at Fitzroy Dental Practice lasts between 60 and 90 minutes. Front teeth (incisors and canines) usually have a single root and are faster to treat. Premolars and molars (the back teeth) contain multiple roots and canals, which makes the procedure more complex and time-consuming.
Risks and Complications
Root canal treatment has a high success rate—often cited around 90-95% for teeth treated by specialists. However, like any medical procedure, there are risks:
- Reinfection: If the restoration leaks or if the canal anatomy was too complex to clean perfectly, infection can return.
- Fracture: As mentioned, the tooth can become brittle. This is why prompt crowning is recommended.
- Instrument separation: Very rarely, a tiny file used to clean the canals can break inside the tooth.
At Fitzroy Dental Practice, we utilise advanced technology and techniques to minimise these risks and ensure the highest standard of care.
Aftercare for Root Canal Treatment
Recovery from a root canal is generally straightforward. You can drive yourself home and return to your normal routine the next day.
What to Expect Immediately After
When the local anaesthetic wears off, you may experience some tenderness in the area for a few days. This is normal; your body is healing from the inflammation caused by the infection. Over-the-counter pain relief, such as ibuprofen or paracetamol, is usually sufficient to manage this discomfort.
Maintaining a Healthy Tooth
Treat your restored tooth just like your natural teeth. Brushing twice a day, flossing daily, and attending regular check-ups are non-negotiable. While the tooth no longer has a nerve, it can still develop cavities or gum disease around the outside.
Cost and Value of Root Canal Treatment in London
The cost of dental care is a significant consideration for many Londoners. In the capital, private root canal treatment generally ranges from £300 to over £950, depending heavily on the complexity of the tooth (molars are more expensive than front teeth) and the expertise of the dentist.
Is It Worth the Investment?
When comparing costs, it is important to look at the alternatives. Extracting a tooth is cheaper upfront, but replacing that tooth with a bridge or a dental implant is significantly more expensive in the long run. An implant, for example, can cost upwards of £2,000. Therefore, saving the natural tooth is usually the most cost-effective decision over a lifetime.

Fitzroy Dental Practice offers interest-free finance options, allowing you to spread the cost of your treatment over 12 months with 0% interest. This helps make high-quality private dental care more accessible and manageable for your budget.

Frequently Asked Questions
Is root canal treatment painful?
This is the biggest myth in dentistry. With modern local anaesthetics, the procedure itself should be painless. Most patients report that it feels no different from having a deep filling done. The pain associated with root canals usually comes from the infection before the treatment, which the procedure alleviates.
How do I know if I need a root canal?
Common signs include severe toothache upon chewing, prolonged sensitivity to hot or cold temperatures, discolouration of the tooth, and swelling and tenderness in the nearby gums. However, sometimes no symptoms are present, and the problem is spotted during a routine X-ray.
What should I do if I have a tooth infection before my appointment?
If you have swelling or severe pain, contact us immediately. We may prescribe antibiotics to control the infection before starting the root canal procedure.
Can I prevent needing a root canal?
The best prevention is good oral hygiene. Brushing, flossing, and regular professional cleanings reduce the risk of deep decay. Additionally, wearing a mouthguard during sports can prevent trauma that might damage the tooth pulp.
