What is a root canal and when do I need one?

A root canal (endodontic treatment) helps save teeth with deep decay, cracks or infections that have reached the pulp. It removes diseased tissue, disinfects the canals and seals them to prevent re‑infection.

When do you need a root canal?

• Persistent or spontaneous pain, or pain when biting.
• Lingering sensitivity to cold/heat.
• Gum swelling, abscess or a pimple/fistula.
• Trauma or fractures exposing the pulp.
• Deep radiographic lesions close to the nerve.

Diagnosis

We combine clinical tests (vitality, percussion, palpation) with periapical X‑rays. In selected cases, CBCT provides 3D detail for complex anatomy or retreatments.

Step‑by‑step treatment

1. Local anesthesia for comfort.
2. Isolation with rubber dam for a clean, safe field.
3. Access to the pulp chamber and canal location.
4. Cleaning and shaping with copious irrigation to remove bacteria and debris.
5. Obturation (3D sealing) with biocompatible materials.
6. Restoration (temporary or definitive). A crown is often advised to protect the tooth long term.

Time and number of visits

Most cases are completed in 1–2 visits (60–90 minutes each), depending on canal anatomy, infection and whether retreatment is needed.

Benefits and alternatives

• Preserving your tooth maintains chewing function and occlusal stability.
• Alternatives: extraction and replacement (implant, bridge, removable prosthesis). We will discuss the best option for your case.

Aftercare and red flags

• Avoid hard foods on the treated side until definitive restoration is placed.
• Mild tenderness is common; use analgesics as indicated.
• Contact us if pain worsens after 48–72 h, swelling increases or you develop fever.
