What the treatment does
Root canal treatment removes infected or inflamed tissue from inside a tooth. The canals are cleaned, filled and sealed, and the tooth may then need a crown. An examination helps determine whether the tooth can be restored.
Could this be right for you?
- An infected or inflamed tooth pulp
- A tooth affected by deep decay or injury
- A previously treated tooth that needs reassessment
Your examination comes first. The findings determine whether this approach fits your teeth, health and goals.
From assessment to aftercare
Assess the tooth
Your dentist examines the tooth and may recommend an X-ray to understand the roots and surrounding bone.
Clean and seal
Local anaesthesia is commonly used. The canals are cleaned and sealed over one or more visits, depending on the tooth.
Protect the restoration
A filling or crown is planned according to the remaining tooth structure and the way you bite.
Risks, limitations & alternatives
Some teeth cannot be saved. Alternatives may include extraction and replacement. Discomfort, persistent infection or the need for further treatment should be discussed before proceeding.
Aftercare & follow-up
Follow the advice given after treatment, avoid biting hard foods on an incompletely restored tooth and attend the recommended follow-up appointments.
Plan the cost before you commit
The tooth involved, complexity of the canals, repeat treatment and the final filling or crown all affect the estimate. Ask whether the restoration is included.
Confirm the consultation fee when booking. Before treatment, request a breakdown of the procedure, materials and follow-up so you can compare the complete plan.
Your treatment estimate checklistQuestions you may have
Is root canal treatment painful?
Local anaesthesia is normally used to manage discomfort during treatment. Tenderness afterwards is possible. Tell your dentist about pain or anxiety so your care can be planned appropriately.
Can it be completed in one visit?
Some cases can be treated in one visit; others need more appointments. Infection, tooth anatomy and the planned restoration influence the decision.
Will I need a crown?
A crown may be recommended to protect a tooth with substantial loss of structure. Your dentist will explain the options after examining it.
