Overview
Root canal treatment removes inflamed or infected tissue from inside a tooth, cleans the space and seals it. A dentist must first examine the tooth to decide whether it can be restored.
When to arrange an examination
- Persistent toothache
- Pain on biting
- Sensitivity that lingers
- Swelling near a tooth
Symptoms can have several causes. An examination is needed before diagnosis or treatment advice.
Assessment and diagnostic needs
A clinical examination and a dental X-ray may be needed. The final plan depends on the tooth, surrounding bone and restorability.
Typical treatment process
- 1
Examination and diagnosis
- 2
Local anaesthesia where appropriate
- 3
Cleaning and shaping the canals
- 4
Sealing the tooth
- 5
Review and restoration planning
Recovery and aftercare
Temporary tenderness can occur. Follow the dentist’s instructions, avoid biting hard on an unrestored tooth and return for the advised crown or restoration.
Important limitations
Not every painful tooth needs root canal treatment, and not every tooth can be saved. Outcomes depend on anatomy, infection, remaining tooth structure and follow-up care.
Frequently asked questions
Will I need an X-ray?
Often, yes. An X-ray helps assess the roots and nearby bone, but the dentist decides what is needed after examination.
Will the tooth need a crown?
Many back teeth need protection after root canal treatment. The recommendation depends on how much healthy tooth remains.
