Why it may be recommended
Root canal treatment treats infection within a tooth. The aim is to preserve a tooth that can be restored, rather than remove it.
What treatment involves
The dentist removes infected tissue, cleans and fills the root canals, and seals the tooth. A filling or crown may then be needed to restore and protect it.
Comfort and recovery
Local anaesthetic is generally used during treatment. Some soreness afterwards can occur. Ask your dentist about pain management and follow-up care.
Your treatment plan
The number of appointments depends on the tooth and the infection. Some teeth cannot be saved, and persistent problems may require further treatment or extraction.
Questions you may have
Does every toothache need a root canal?
No. A dental examination is needed to identify the cause and the appropriate treatment.
Will I need a crown?
A crown may be recommended depending on the tooth and how much healthy structure remains.
Can I delay an assessment?
Contact a dentist promptly for tooth pain or swelling. Do not rely on this page to diagnose the cause.
