Root Canal vs Extraction: Which Option Is Better?

When a tooth is badly damaged or infected, treatment usually comes down to a root canal or extraction. This guide explains how each option works, their pros and cons, and what factors influence the decision.

When a tooth is badly damaged or infected, treatment usually comes down to two options: root canal treatment or tooth extraction. Both are legitimate dental procedures, and neither should be viewed as a lesser choice — the right option depends entirely on the condition of the tooth and your overall oral health.

This guide explains how each treatment works, the advantages and considerations of both, and how dentists assess which approach is most suitable for your individual situation. Understanding the differences can help you feel more confident when discussing your options with your dentist.

What Is a Root Canal Treatment?

Root canal treatment is a procedure designed to save a tooth that has become infected or inflamed internally. Rather than removing the tooth altogether, the aim is to preserve the natural tooth structure while eliminating the source of infection.

During root canal treatment, the dentist removes the infected pulp tissue from inside the tooth, cleans and shapes the root canals, and seals them with a biocompatible material. In many cases, a crown is placed afterwards to protect the treated tooth and restore its strength.

Root canal treatment is typically considered when the infection has not spread beyond the point of effective treatment and when enough healthy tooth structure remains to support a restoration.

What Does Tooth Extraction Involve?

Tooth extraction involves the complete removal of a tooth from its socket in the jawbone. It is a common dental procedure that is performed under local anaesthetic to keep the patient comfortable.

Extraction may be necessary when a tooth is too severely damaged to be restored, when infection is extensive, or when keeping the tooth could put surrounding teeth or overall oral health at risk.

After extraction, the gap left behind may need to be addressed with a replacement option such as a dental implant, bridge, or denture — depending on the location of the tooth, the patient's oral health, and their preferences.

Benefits of Choosing a Root Canal

Where clinically appropriate, preserving a natural tooth through root canal treatment offers several advantages:

  • Keeping the natural tooth — your own tooth is almost always the best option for function and feel, provided it can be maintained long-term
  • Maintaining bite and alignment — a preserved tooth helps keep surrounding teeth in their correct positions, preventing shifting or tilting
  • Avoiding a gap — retaining the tooth eliminates the need for a replacement, which simplifies ongoing care and reduces the overall treatment involved
  • Natural appearance — a restored root-treated tooth, particularly when protected with a crown, looks and functions like a natural tooth

It is worth noting that root canal treatment is not suitable for every situation. The tooth needs to have sufficient remaining structure and the infection needs to be manageable for this approach to be a viable long-term option.

Situations Where Extraction May Be Recommended

Extraction is not a last resort or a sign of failure — it is a considered clinical decision that may be the most appropriate option in certain circumstances:

  • Severe structural damage — if the tooth is fractured below the gum line or has lost too much structure to support a restoration
  • Advanced infection — when the infection has progressed significantly and is unlikely to resolve with root canal treatment alone
  • Poor long-term prognosis — if the tooth is unlikely to function well long-term even after treatment, extraction may offer a more predictable path forward
  • Periodontal involvement — extensive gum disease or bone loss around the tooth may make saving it impractical

Your dentist will explain the reasoning behind an extraction recommendation clearly and discuss what replacement options are available.

Pain and Recovery Comparison

Concerns about pain are natural when considering either treatment. Both root canal treatment and extraction are performed under local anaesthetic, so sharp pain during the procedure is typically prevented.

During treatment:

  • Both procedures involve numbing the area thoroughly before any work begins
  • Patients may feel pressure or vibration during either treatment, but this is generally not painful
  • Individual experiences can vary, and your dentist will check in with you throughout

Post-treatment recovery:

  • Root canal — mild soreness and tenderness around the treated tooth for a few days is common, usually manageable with over-the-counter pain relief
  • Extraction — some swelling and discomfort around the extraction site is expected. Recovery may take a little longer, particularly for more complex removals

Neither treatment should involve significant pain during the procedure itself. Post-treatment discomfort varies between individuals, and your dentist will provide aftercare guidance tailored to your situation.

Long-Term Implications of Each Option

The decision between root canal and extraction has implications that extend well beyond the initial appointment. Understanding these helps inform a more complete picture:

  • After extraction — the gap left by a missing tooth may need to be filled with a replacement such as an implant, bridge, or denture. Without replacement, surrounding teeth may shift over time
  • After root canal — the treated tooth will need a permanent restoration, typically a crown, to protect it. With proper care, a root-treated tooth can function well for many years
  • Impact on surrounding teeth — keeping a natural tooth in place helps maintain the alignment and function of neighbouring teeth, whereas a gap may lead to gradual changes in bite and spacing

Both options can lead to good outcomes when chosen appropriately. The key is making an informed decision based on the specific condition of the tooth and your broader oral health.

Cost and Treatment Planning Considerations

Cost is a practical factor that many patients consider when choosing between treatments. It is important to think about both the immediate and longer-term financial picture:

  • Immediate costs — the upfront cost of root canal treatment, including a crown, may be higher than a straightforward extraction
  • Long-term costs after extraction — if a replacement tooth is needed, the combined cost of extraction plus an implant, bridge, or denture can be considerable
  • Personal priorities — some patients prioritise preserving their natural tooth, while others may prefer a different approach based on their circumstances

Your dentist can outline the costs involved with each option during your consultation, helping you make a decision that works for both your oral health and your budget. You can also review the practice's fee guide for further information.

How Dentists Decide Between Root Canal and Extraction

The recommendation your dentist makes is based on a thorough assessment of several clinical factors. This is not a one-size-fits-all decision — it is tailored to your individual situation.

Factors your dentist will consider include:

  • Tooth condition — how much healthy tooth structure remains, whether there are cracks or fractures, and whether the tooth can support a restoration
  • Gum and bone health — the condition of the surrounding tissues plays a significant role in determining whether a tooth can be maintained long-term
  • Overall oral health — the health of neighbouring teeth and the patient's general dental condition are taken into account
  • Patient preferences — your priorities, concerns, and practical considerations are all part of the conversation

A good dentist will explain the reasoning behind their recommendation clearly, outline the alternatives, and support you in making an informed choice.

What Happens If a Tooth Is Extracted and Not Replaced?

After an extraction, some patients wonder whether they actually need to replace the missing tooth. While not every extraction requires an immediate replacement, leaving a gap can have consequences over time:

  • Tooth movement — neighbouring teeth may gradually shift or tilt into the gap, affecting alignment
  • Bite changes — an uneven bite can lead to discomfort, uneven wear on remaining teeth, or jaw tension
  • Bone loss — the jawbone in the area of the missing tooth may gradually lose volume over time without the stimulation a tooth root provides

Your dentist will discuss whether replacement is recommended based on the location of the extracted tooth and how the gap may affect your oral health over time. In some cases — such as wisdom teeth — replacement is typically not needed.

Frequently Asked Questions

Is a root canal better than extraction?

Where a tooth can be saved and has a reasonable long-term prognosis, root canal treatment is often preferred because it preserves the natural tooth. However, extraction may be the more appropriate option in certain situations, particularly when the tooth is too damaged to restore.

When is extraction preferred over root canal?

Extraction may be recommended when the tooth has severe structural damage, extensive infection that is unlikely to resolve with root canal treatment, or significant bone loss around the root. Your dentist will explain the reasoning behind their recommendation.

Does a root canal last longer than an extraction?

A root-treated tooth, when properly restored and maintained, can function well for many years. After extraction, the longevity of the outcome depends on the replacement option chosen and how well it is maintained. Both can offer long-lasting results with appropriate care.

Is extraction cheaper than a root canal?

The upfront cost of extraction is often lower. However, if a replacement tooth is needed afterwards — such as an implant or bridge — the total cost may be comparable to or exceed that of root canal treatment with a crown. It is important to consider the full picture.

What happens if I don't replace an extracted tooth?

Over time, neighbouring teeth may shift into the gap, your bite may change, and the jawbone in that area may lose volume. Your dentist will discuss whether replacement is recommended based on the tooth's location and your overall oral health.

Can an extracted tooth be replaced later?

Yes, in most cases a missing tooth can be replaced at a later stage with an implant, bridge, or denture. However, delaying replacement may allow some bone loss to occur, which could affect the options available. Discussing timing with your dentist is advisable.

How do I decide between root canal and extraction?

The best approach is to discuss your options with your dentist, who can assess the tooth and explain the pros and cons of each treatment as they apply to your situation. There is no universal answer — it depends on the condition of the tooth and your personal priorities.
