Root Canal vs Tooth Extraction: Which Is Right for You?
Facing a damaged or infected tooth? Understanding the difference between saving it with root canal treatment and removing it with extraction helps you feel more informed and confident about your next step.
When a tooth is severely decayed, infected, or damaged, you may be told it needs either root canal treatment in London or tooth extraction in London. Both are common procedures — but they serve very different purposes. One aims to save the tooth; the other removes it entirely.
This guide explains the key differences between root canal treatment and tooth extraction — covering procedure, recovery, cost, and long-term outcomes — so you can better understand what each involves. The right treatment will always depend on a thorough clinical assessment by your dentist, who will recommend whichever option gives you the best outcome.
The information on this page is for general guidance only. Treatment suitability, outcomes, and costs vary between individuals. A clinical examination is necessary before any treatment can be recommended.
Root Canal vs Extraction: Side-by-Side
A quick overview of the key differences between root canal treatment and tooth extraction.
| Feature | Root Canal Treatment | Tooth Extraction |
|---|---|---|
| Procedure Type | Endodontic — removes infected pulp, preserves tooth | Surgical — removes the entire tooth |
| Treatment Time | Typically 1–2 appointments over 1–2 weeks | Usually a single appointment — 20–60 minutes |
| Pain Management | Local anaesthetic — comfortable throughout | Local anaesthetic — comfortable throughout |
| Tooth Preservation | Yes — the natural tooth is saved | No — the tooth is permanently removed |
| Aesthetics | Natural tooth retained, usually restored with a crown | Gap remains unless replaced with implant, bridge, or denture |
| Cost (UK Range) | From £695 (front) – £895 (molar) | From £250 – £650 |
| Recovery | Mild sensitivity for a few days — normal function resumes quickly | 1–2 weeks for socket healing — soft diet initially |
| Suitability | Teeth with sufficient healthy structure remaining | Severely damaged, fractured, or non-restorable teeth |
This table provides a general overview. The most suitable option depends on your individual clinical assessment.
What Is Root Canal Treatment?
Root canal treatment (also called endodontic treatment) is a procedure designed to save a tooth that has become infected or badly damaged. The infected pulp — the soft tissue containing nerves and blood vessels inside the tooth — is carefully removed, the root canals are cleaned and disinfected, and the tooth is sealed to prevent further infection.
The treated tooth is then usually restored with a dental examination for diagnosis followed by a crown to protect it and restore full function. Root canal treatment allows you to keep your natural tooth, maintain your bite, and avoid the need for a replacement.
Potential Benefits
- Saves the natural tooth — no gap, no replacement needed
- Relieves pain caused by infection or inflammation
- Prevents infection from spreading to neighbouring teeth or bone
- Maintains natural bite alignment and jaw function
- Avoids the cost and complexity of tooth replacement
Suitable Candidates May Include
- Patients with deep decay that has reached the pulp
- Those with a dental abscess or persistent toothache
- Patients whose tooth has sufficient healthy structure to be saved
- Those who want to preserve their natural tooth rather than extract it
Your dentist will assess whether root canal treatment is clinically appropriate for your tooth.
What Is Tooth Extraction?
Tooth extraction is the complete removal of a tooth from its socket. It is recommended when a tooth is too damaged, decayed, or infected to be saved — or when keeping it poses a risk to your overall oral health. Extractions range from simple procedures (for teeth that are visible and accessible) to surgical extractions (for teeth that are impacted or broken below the gum line).
If you are experiencing severe tooth pain or sudden dental problems, our emergency dental care team can assess whether the tooth can be saved or whether extraction is the most appropriate course of action. After extraction, your dentist will discuss options for replacing missing teeth to maintain your bite and oral function.
Potential Benefits
- Removes the source of infection or pain completely
- Prevents infection from spreading to other teeth or bone
- Usually completed in a single appointment
- Lower upfront cost than root canal treatment
- May be the only option when a tooth cannot be saved
Suitable Candidates May Include
- Patients with teeth too damaged or decayed to restore
- Those with vertical root fractures that cannot be repaired
- Patients with severe bone loss around the tooth
- Those with impacted wisdom teeth causing problems
Your dentist will only recommend extraction when saving the tooth is no longer clinically viable.
How Do They Compare?
Understanding these differences helps clarify when saving a tooth is possible and when removal may be the better option.
Tooth Preservation vs Removal
The fundamental difference is that root canal treatment saves the natural tooth, while extraction removes it permanently. Preserving a natural tooth is generally preferred wherever clinically possible — it maintains your bite, prevents neighbouring teeth from shifting, and avoids the need for a replacement.
Long-Term Outcomes
A successfully treated root canal tooth can function normally for many years. After extraction, the gap must be managed — otherwise adjacent teeth may shift and bone loss can occur at the extraction site. Replacement options such as dental implants or bridges add additional treatment and cost.
Treatment Complexity
Root canal treatment is a more involved procedure — typically requiring 1–2 appointments and a follow-up crown. Extraction is generally a shorter, single-visit procedure — but if the tooth needs to be replaced, the overall treatment journey becomes more complex.
Recovery
After root canal treatment, most patients experience mild sensitivity for a few days before returning to normal function. After extraction, socket healing takes 1–2 weeks, with a soft diet recommended initially. Both treatments are manageable with standard aftercare.
Cost
Extraction has a lower upfront cost than root canal treatment. However, if the extracted tooth needs replacing with an implant, bridge, or denture, the total long-term cost can exceed that of root canal treatment. Your dentist will discuss all costs and options transparently.
Pros and Cons
Both treatments have an important role in dentistry. Here is a balanced overview of each.
Root Canal Treatment
Saves the natural tooth by removing infection
Pros
- Preserves the natural tooth — no gap, no replacement needed
- Maintains natural bite alignment and jaw function
- Relieves pain caused by infection or abscess
- Prevents neighbouring teeth from shifting
- Often more cost-effective long-term than extraction + replacement
Cons
- Higher upfront cost than a simple extraction
- Typically requires 1–2 appointments plus a crown
- The treated tooth may become brittle over time without a crown
- Not suitable for all cases — some teeth cannot be saved
Tooth Extraction
Complete removal of a damaged or non-restorable tooth
Pros
- Removes the source of infection or pain completely
- Usually completed in a single appointment
- Lower upfront cost than root canal treatment
- May be the only viable option for severely damaged teeth
- Straightforward recovery for simple extractions
Cons
- The tooth is permanently lost — it cannot be restored
- Adjacent teeth may shift into the gap over time
- Bone loss can occur at the extraction site
- Replacement (implant, bridge, or denture) adds significant cost
Cost Comparison
Costs vary depending on the complexity of the case and individual clinical factors.
Root Canal Treatment
From £695
Front tooth — from £895 for molars
Root canal treatment costs more upfront than a simple extraction, reflecting the clinical skill, time, and precision required to save the tooth. A crown is usually recommended afterwards (additional cost) to protect the treated tooth long-term. However, this approach avoids the ongoing cost of replacing a missing tooth with an implant or bridge.
Final cost confirmed at your appointment. Molar root canals are more complex and cost more.
Tooth Extraction
From £250
Simple — up to £650 for surgical
Extraction has a lower upfront cost, but the total expense can increase significantly if the tooth needs replacing. A dental implant for missing teeth or bridge will add to the overall investment. Your dentist will discuss all costs and long-term tooth replacement solutions transparently before any treatment begins.
Final cost confirmed after consultation. Surgical extractions cost more than simple extractions.
Final costs are confirmed after your consultation and clinical assessment. A full written estimate is always provided before treatment begins.

Your dentist will recommend the most appropriate option based on a thorough clinical examination. These general scenarios may help guide your understanding.
Best for Saving Natural Teeth
If the tooth has enough healthy structure remaining and the infection can be resolved, root canal treatment is generally the preferred approach. Saving your natural tooth preserves your bite, prevents adjacent teeth from shifting, and avoids the complexity and cost of a replacement.
Best for Severe Damage or Infection
If the tooth is too severely damaged to be restored — such as a vertical root fracture, extensive bone loss, or failed previous root canal treatment — extraction may be the only viable option. Removing the tooth eliminates the source of infection and allows your dentist to plan an appropriate replacement.
Best for Long-Term Oral Health
Where clinically possible, preserving your natural tooth with root canal treatment is generally better for long-term oral health. A natural tooth maintains bone density, bite function, and alignment — advantages that even the best replacement cannot fully replicate.
Best for Affordability
Extraction has a lower upfront cost. However, if the extracted tooth needs replacing, the total expense — including an implant, bridge, or denture — can exceed the cost of root canal treatment. For suitable cases, root canal treatment may prove more economical over the long term.
The Right Decision Starts with a Diagnosis
You do not need to make this decision alone. During your dental examination, your dentist will take X-rays, assess the extent of the damage, and explain whether root canal treatment can save the tooth or whether extraction is the more appropriate course of action. A full treatment plan and written estimate will always be provided before any treatment begins.
Your dentist will recommend the most suitable treatment following a thorough clinical assessment.
