Root Canal vs Dental Implant: Which Is Right for You?
Should you save your natural tooth or replace it entirely? Understanding the difference between root canal treatment and a dental implant helps you make a more informed and confident decision.
When a tooth is severely damaged or infected, you may face a choice: try to save it with root canal treatment in London, or remove it and replace it with a dental implant in London. Both are well-established treatments — but they serve fundamentally different purposes and suit different clinical situations.
This guide explains the key differences between root canal treatment and dental implants — covering procedure, cost, longevity, and long-term outcomes — so you can understand what each involves. The right treatment will always depend on a thorough clinical assessment by your dentist, who will recommend the option that 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 Implant: Side-by-Side
A quick overview of the key differences between root canal treatment and dental implants.
| Feature | Root Canal Treatment | Dental Implant |
|---|---|---|
| Procedure Type | Endodontic — saves the natural tooth | Surgical — replaces the tooth with an artificial root and crown |
| Treatment Time | 1–2 appointments over 1–2 weeks, plus crown | 3–6 months total including healing and crown placement |
| Tooth Preservation | Yes — the natural tooth is preserved | No — the tooth is removed and replaced |
| Longevity | Typically 10–15+ years with a crown | Implant root can last decades; crown may need replacing after 10–15 years |
| Aesthetics | Natural tooth retained, usually restored with a crown | Custom-made crown designed to match surrounding teeth |
| Cost (UK Range) | From £695 (front) – £895 (molar) + crown | From £2,950 (inc. crown) |
| Recovery | Mild sensitivity for a few days | 1–2 weeks initial healing; 3–6 months for full integration |
| Suitability | Teeth with sufficient healthy structure remaining | Missing teeth or teeth too damaged to save |
This table provides a general overview. The most suitable option depends on your individual clinical assessment.
What Is Root Canal Treatment?
Root canal treatment (endodontic treatment) is a procedure designed to save your natural tooth when the pulp — the soft tissue containing nerves and blood vessels inside the tooth — becomes infected or inflamed. The infected pulp is carefully removed, the root canals are cleaned and disinfected, and the tooth is sealed to prevent further infection.
The treated tooth is then typically restored with a crown to protect it and restore full function. Root canal treatment allows you to keep your natural tooth, maintain your bite alignment, and avoid the need for a replacement.
Potential Benefits
- Preserves the natural tooth — no extraction, no replacement
- Relieves pain caused by infection or abscess
- Maintains natural bite alignment and jaw function
- Less invasive than extraction followed by implant surgery
- Lower overall cost than extraction plus implant placement
Suitable Candidates May Include
- Patients with deep decay that has reached the tooth pulp
- Those with a dental abscess or persistent toothache
- Patients whose tooth has sufficient healthy structure to be saved
- Those who prefer to preserve their natural tooth where possible
Your dentist will assess whether root canal treatment is clinically appropriate for your tooth.
What Is a Dental Implant?
A dental implant is an artificial tooth root — a small titanium post that is surgically placed into the jawbone to replace a missing tooth. Over several months, the implant integrates with the bone (a process called osseointegration), creating a stable foundation for a custom-made crown that looks and functions like a natural tooth.
Dental implants are considered one of the most reliable missing teeth treatment options available. They are suitable for patients who have already lost a tooth, or whose tooth is too damaged to be saved through root canal treatment or other restorative approaches.
Potential Benefits
- Replaces the entire tooth — root and crown — for a complete solution
- Preserves jawbone density by stimulating the bone like a natural root
- Designed for long-term function — the implant root can last decades
- Custom-made crown provides natural aesthetics
- Does not affect neighbouring teeth — stands independently
Suitable Candidates May Include
- Patients with a missing tooth or teeth too damaged to restore
- Those with adequate jawbone density to support an implant
- Patients in good general health who do not smoke
- Those seeking a permanent, long-term tooth replacement
Your dentist will confirm whether you are a suitable candidate following a clinical examination and X-rays.
How Do They Compare?
Understanding these differences helps clarify when saving a tooth is the better option and when replacing it may be more appropriate.
Saving vs Replacing the Tooth
Root canal treatment preserves your natural tooth by removing the infection and sealing it. A dental implant replaces the tooth entirely with an artificial root and crown. Preserving a natural tooth is generally preferred where clinically possible — but when a tooth cannot be saved, an implant offers a strong, permanent alternative.
Treatment Process and Timeline
Root canal treatment typically involves 1–2 appointments over 1–2 weeks, plus a follow-up crown. Dental implant treatment is a longer process — involving extraction (if needed), implant placement, a healing period of 3–6 months for osseointegration, and then crown placement. The implant journey requires more appointments and patience.
Longevity and Maintenance
A root canal treated tooth, restored with a crown, can last 10–15 years or more with good care. Dental implants are designed to be long-lasting — the titanium root can last decades, though the crown may need replacing after 10–15 years. Both require excellent oral hygiene and regular dental check-ups.
Cost
Root canal treatment is significantly less expensive than a dental implant, especially when the tooth already has sufficient structure. However, if a root canal fails and the tooth later needs extraction and an implant, the total cost may exceed that of placing an implant initially. Your dentist will discuss all costs transparently.
Suitability Based on Tooth Condition
Root canal treatment requires enough healthy tooth structure to support a crown. If the tooth is too severely damaged, fractured below the gum line, or has insufficient bone support, an implant may be the more appropriate solution. Your dentist will assess the tooth thoroughly before recommending either option.
Pros and Cons
Both treatments play an important role in modern dentistry. Here is a balanced overview of each.
Root Canal Treatment
Saves the natural tooth by removing infection
Pros
- Preserves your natural tooth — no extraction required
- Maintains natural bite, alignment, and sensation
- Less invasive and shorter treatment timeline
- Significantly lower cost than implant treatment
- Prevents neighbouring teeth from shifting
Cons
- Not suitable for all teeth — some are too damaged to save
- The treated tooth may become brittle without a crown
- Small risk of re-infection requiring retreatment
- May not last as long as a well-maintained implant
Dental Implant
Complete tooth replacement with artificial root and crown
Pros
- Complete tooth replacement — root and crown
- Preserves jawbone density and prevents bone loss
- Implant root designed to last decades with proper care
- Looks and functions like a natural tooth
- Does not rely on or affect neighbouring teeth
Cons
- Significantly higher cost than root canal treatment
- Longer treatment timeline — typically 3–6 months
- Requires surgery and adequate jawbone density
- Not suitable for all patients (smokers, certain medical conditions)
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 is significantly more affordable than an implant. The cost covers the endodontic procedure itself — a crown to protect the treated tooth is usually recommended in addition (separate cost). Even including the crown, root canal treatment is typically far less expensive than implant placement.
Final cost confirmed at your appointment. Molar root canals cost more due to greater complexity.
Dental Implant
From £2,950
Including implant, abutment, and crown
The higher cost reflects the surgical procedure, the titanium implant, the abutment, the custom-made crown, and the multiple appointments required. As a long-term tooth replacement solution, an implant represents a significant investment — but one designed to last for many years.
Final cost confirmed after consultation. Additional procedures such as bone grafting may apply.

Your dentist will recommend the most appropriate option based on a thorough clinical examination. These general scenarios may help guide your understanding.
Best for Preserving Natural Teeth
If the tooth has sufficient healthy structure and the infection can be resolved, root canal treatment is generally the preferred option. Preserving your natural tooth maintains bite function, avoids surgery, and costs significantly less than an implant. Where saving the tooth is viable, it is usually the clinically preferred approach.
Best for Long-Term Replacement
If the tooth is missing or cannot be saved, a dental implant provides a strong, permanent replacement that looks and functions like a natural tooth. The implant root integrates with the jawbone, preserving bone density and providing a stable foundation designed to last for many years.
Best for Severely Damaged or Missing Teeth
When a tooth is fractured below the gum line, has extensive bone loss, or has already been lost, root canal treatment is not possible. In these cases, a dental implant — or an alternative replacement such as a bridge — is the appropriate course of action to restore function and appearance.
Best for Overall Oral Health
Where clinically possible, keeping your natural tooth through root canal treatment is generally better for overall oral health. A natural tooth maintains bone density, bite alignment, and the natural feel of your smile. However, a well-placed implant also preserves bone and provides excellent long-term function.
The Right Decision Starts with a Diagnosis
You do not need to make this decision alone. During your dental examination for diagnosis, your dentist will take X-rays, assess the condition of the tooth, and explain whether root canal treatment can save it or whether a dental implant is the more appropriate solution. 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.
