In short
- The tooth is fully numbed; most patients feel pressure, not pain.
- Severe pain usually comes from the inflammation before treatment, and treatment relieves it.
- A few days of tenderness afterwards is normal.
Does a root canal hurt?
Usually not. The tooth is fully numbed with local anaesthetic, so most patients feel pressure or light vibration rather than pain. The pain people link to root canals is usually the inflammation before treatment, and treatment is what relieves it.
Why are some teeth harder to numb?
A very inflamed tooth can need extra anaesthetic or a different technique. The doctor checks the tooth is fully numb before starting, and you can raise your hand at any moment to pause.
What will I feel after a root canal?
It is normal for the tooth to feel tender when you bite for a few days. This usually settles with the ordinary painkillers the doctor recommends and improves day by day.
When should I call the clinic?
Call if swelling appears, if the pain gets worse after the third day instead of better, or if the temporary filling falls out.
Other questions patients ask
Can I go back to work after a root canal?
Most people go back to work the same day. The numbness can last a few hours, so wait before eating.
