Dental Pain After Root Canal : What You Need to Know

How bad does a root canal hurt 1–10?


With today’s advanced techniques and numbing agents, most patients rate the actual root canal procedure between 1 and 3 on the pain scale. Many say it feels no worse than getting a filling.

Does it hurt after a root canal?


Some mild discomfort is normal for a few days. This is typically due to inflammation around the treated tooth. However, if the pain persists or worsens, it could signal a complication like a failed root canal.

What To Do About Severe or Lasting Pain


If you experience ongoing or intense pressure or throbbing, don’t ignore it. Try:

  • Over-the-counter pain medication
  • Cold compresses
  • Avoiding hard foods on the treated side

If symptoms continue, contact your dentist or an endodontist in Vancouver BC right away. In rare cases, retreatment or additional procedures may be necessary.

Why Might There Be Pain After a Root Canal?


  • Inflammation of surrounding tissues
  • Incomplete cleaning of the root canals
  • Cracked tooth structure
  • Missed canals or hidden infections

All of these can contribute to discomfort or the need for additional treatment. It’s why working with an experienced provider matters.

How much pain is normal?


Mild soreness or tenderness when chewing is normal for up to a week. Swelling or sharp pain is not. If you experience these symptoms, consult your dental clinic in Vancouver BC to rule out complications.

How long will the pain last after a root canal?


For most patients, post-procedure discomfort subsides within 3–7 days. Pain that lasts longer may be a sign of a failed root canal or infection.

Should you be nervous about a root canal?


Not at all. Thanks to modern dentistry, root canals are no longer the painful procedures they once were. Most patients are pleasantly surprised by how quick and easy it feels.

How to tell if a root canal failed?


Signs of a failed root canal include:

  • Persistent or returning pain
  • Swelling or pus
  • Pain when biting or applying pressure
  • A pimple-like bump near the tooth

In such cases, you may need retreatment or an alternative treatment, such as dental implant.

Pain Recovery Timeline


Here’s what to expect after your root canal:

  • Day 0–2: Mild swelling or pressure sensitivity. Rest, apply cold compresses, and use OTC pain relief.
  • Day 3–7: Pain should steadily decrease. If swelling or discomfort increases, call your dentist.

After Week 1: Monitor for unusual symptoms and plan for your permanent crown placement.

Managing Pain at Home (Safe & Evidence-Based)


  • Over-the-counter medication (follow package instructions and consult if unsure)
  • Cold compress for 15–20 minutes at a time
  • Warm saltwater rinses 2–3 times a day
  • Soft diet to avoid pressure on the treated tooth
  • Elevate your head when sleeping to reduce throbbing
