Extraction
Removing the tooth may be safer when the tooth cannot be restored or infection risk is high.
Root canal treatment
Root canal treatment may be considered when the nerve inside a tooth is inflamed or infected and the tooth is suitable to save.
Do I need root canal treatment, or is there another option?
Root canal treatment is used to treat infection or irreversible inflammation inside a tooth. It is only sensible when the tooth can be restored predictably afterwards, so the decision should include the nerve, root, crack risk, remaining tooth structure and alternatives.
- Start with the problem that made root canal treatment seem relevant.
- The dentist checks whether the treatment fits the tooth, gums, bite, timing and alternatives.
- If there are simpler, staged or no-treatment options, those should be discussed before you decide.
Assessment steps for root canal treatment
- Test the tooth nerve, bite tenderness, gum support and whether symptoms match X-ray findings.
- Assess cracks, decay depth, restorability and whether the tooth can be sealed properly afterwards.
- Compare root canal treatment with extraction, referral, stabilisation or monitoring before committing.
When this treatment may be appropriate
- The tooth nerve is irreversibly inflamed or infected.
- The tooth has enough structure and support to be restored after treatment.
- Saving the tooth is predictable enough to justify the time, cost and maintenance involved.
When it may not be the right treatment
- The tooth is cracked too deeply or cannot be restored predictably.
- Gum or bone support is poor enough that saving the tooth is unlikely to last.
- Extraction and replacement or monitoring is a more appropriate option.
Who may benefit
- Patients who want to keep a natural tooth when the outlook is reasonable.
- Teeth with nerve infection where removal is not the preferred first option.
- Situations where saving the tooth supports chewing, bite stability or appearance.
Suitability checks before root canal treatment
- Whether testing confirms irreversible inflammation or infection from the tooth.
- Whether enough tooth remains for a durable filling or crown after treatment.
- Whether cracks, gum support or bite load make saving the tooth unreliable.
Alternatives to consider
Monitoring or stabilising first
Some uncertain teeth need further testing or short-term stabilisation before a long-term decision.
Referral
Complex roots, retreatment or uncertain cracks may need specialist endodontic advice.
Options to compare before root canal treatment
Root canal vs extraction
Root canal treatment aims to save the tooth when restorable; extraction may be more predictable when cracks, infection or structure make saving unlikely.
Root canal vs filling
A filling can repair structure, but it cannot resolve irreversible nerve inflammation or infection inside the tooth.
Root canal vs referral
Specialist care may be better for complex roots, retreatment, unclear diagnosis or high-value teeth with uncertain prognosis.
How we decide
How we decide
- Whether symptoms and testing suggest irreversible nerve inflammation or infection.
- Root shape, crack risk, X-ray findings and gum support.
- Whether the tooth can be sealed and restored well afterwards.
- The value of the tooth compared with extraction and replacement options.
Pricing and complexity factors
What can affect pricing and complexity
- Number and shape of canals, infection level and whether retreatment is involved.
- Whether a crown, build-up, post, referral or staged appointments are needed.
- Crack risk and uncertainty about whether the tooth can be restored predictably.
What to expect
What to expect
- Assessment, X-rays and testing to confirm the likely source of pain or infection.
- Cleaning, shaping and sealing the canals inside the tooth when treatment is appropriate.
- A restoration plan afterwards, often involving a filling or crown depending on tooth strength.
Recovery and maintenance
Recovery and maintenance expectations
- Tenderness after treatment can occur while inflammation settles, especially if the tooth was painful to bite on beforehand.
- Long-term stability depends on the final restoration, sealing, bite protection and review of any previous infection.
Keeping the result stable
Keeping the result stable
- Root-treated teeth still need good sealing, bite protection and routine review.
- A weak back tooth may need a crown or stronger restoration to reduce fracture risk.

Common questions
Common questions
Does tooth pain always mean root canal treatment?
No. Tooth pain can come from several causes. Root canal treatment is only considered when the nerve is irreversibly inflamed or infected and the tooth is worth saving.
Is extraction an alternative to root canal treatment?
Yes. Extraction may be considered when the tooth cannot be restored predictably or saving it does not make sense.
Unsure whether this treatment is right?
