Does a Root Canal Hurt? What to Expect, Step by Step

root canal treatment | Shore Side dentistry Oakville

For most people, a root canal feels similar to having a filling. The tooth is numbed with local anesthetic before treatment starts, so you should feel pressure rather than pain. Many patients find the procedure relieves the pain they had before, which usually came from the infection, not the treatment.

Why a Root Canal Is Needed

Inside each tooth is soft tissue called the pulp, which contains nerves and blood vessels. When the pulp becomes infected or inflamed, from deep decay, a crack, or repeated dental work, it can cause pain and swelling and may lead to an abscess. A root canal removes the damaged pulp so the tooth can be saved instead of pulled.

Signs You Might Need One

  • Lingering pain or sensitivity to hot or cold
  • Pain when you bite or chew
  • A tooth that has darkened
  • Swelling or a pimple-like bump on the gum
  • Tenderness in the gum near one tooth

Sometimes there are no symptoms at all, and the problem is found on an X-ray during a regular exam.

What Happens, Step by Step

  • Exam and X-ray to confirm the problem and see the shape of the roots.
  • Numbing: local anesthetic is given so the area is comfortable.
  • Cleaning: the infected pulp is removed and the inside of the tooth is cleaned and shaped.
  • Sealing: the canals are filled and sealed to keep bacteria out.
  • Protecting the tooth: a filling, and often a crown, is placed to restore strength.

Does It Hurt Afterwards?

It is normal for the tooth to feel tender for a few days. Over-the-counter pain relief usually manages this well. Avoid chewing hard foods on that side until the tooth has its final filling or crown. Call your dentist if pain or swelling gets worse instead of better.

Why a Crown Is Often Recommended

Teeth that need a root canal have often lost a lot of structure, and back teeth take heavy chewing forces. A crown covers and protects the tooth so it is less likely to crack.

Is Pulling the Tooth Easier?

Removing a tooth may seem simpler, but a missing tooth can let nearby teeth shift and may need an implant or bridge later. When a tooth can be saved, a root canal is usually the better long-term choice. Your dentist will explain the options for your situation.
