Key points
- A root canal typically takes 3–4 sittings over about 8–10 days, depending on the tooth.
- Each sitting is done under local anaesthesia, so it should feel much like a long filling.
- Mild soreness when biting for a few days afterwards is common.
- Finish every sitting and get the crown — a temporary filling is not a permanent seal.
What happens at each sitting
- Diagnose & relieveAn X-ray and examination, local anaesthesia, then the infected pulp is accessed and cleaned out to relieve pain.
- Clean & shapeThe canals are carefully cleaned, shaped and disinfected, with medication placed inside so the tooth can settle.
- Seal the canalsOnce the tooth is symptom-free, the canals are filled and sealed to keep bacteria out.
- Restore & protectA core build-up and a crown give the tooth back its strength so it can chew normally again.
Why it takes more than one visit
An infected tooth often needs time to settle. Medication placed inside the canals between sittings helps control the infection before the tooth is sealed.
Molars can have three or four narrow, curved canals that take time to clean thoroughly. Sealing a tooth only once it is symptom-free lowers the chance of the infection returning.
How long is each sitting?
Most sittings last between 30 and 90 minutes, depending on the tooth and the step. Molars and re-treatments take longer than front teeth. You will be told roughly how long to set aside when you book.
Between sittings
- Chew on the other side and avoid hard or sticky food on the treated tooth
- Keep the temporary filling in place, and call if it falls out
- Brush and clean gently around the tooth as usual
- Take medicines only as prescribed
- Don't skip or delay appointments — an unsealed tooth can be re-infected or crack
Recovery: what's normal and what isn't
Tenderness when biting and mild soreness for two to three days are common, and usually settle on their own. Most people return to work or college the same day once the numbness wears off.

Frequently asked questions
Can I go to work after a root canal?
Most people can. Once the numbness wears off you can eat soft food and return to normal activities the same day.
Does a root canal hurt?
The tooth is numbed with local anaesthesia, so treatment usually feels much like a long filling. Many patients find it relieves the pain they came in with.
What if I miss a sitting?
Call to rebook as soon as possible. Leaving a tooth unsealed for too long can let infection return or the weakened tooth crack.
