Just had a root canal and not sure if what you’re feeling is normal? You’re not alone. At Eastern Idaho Endodontics, one of the most common questions we get after treatment is:
“Should my tooth still hurt?”

The short answer? Some discomfort is normal—but ongoing or worsening pain might be a red flag. We will walk you through what to expect, what’s totally okay, and when it’s time to pick up the phone and call your dentist or endodontist when you experience root canal pain.

Why Pain Happens After a Root Canal

Let’s start with the good news: the source of infection and inflammation inside your tooth has been removed. That means your body is now in healing mode. But healing doesn’t always happen silently.

You might still feel:

  • Soreness in the jaw or gums

  • Tenderness near the treated tooth

  • Slight pressure or sensitivity when biting

  • Mild swelling in the surrounding area

All of this is part of your body’s natural response to dental treatment and should improve with time.

What’s Considered “Normal” Pain After a Root Canal?

Here’s what you can expect in the first few days after treatment:

Mild to moderate soreness

This often comes from the cleaning and shaping process that took place inside your tooth and the surrounding tissues. You might feel some tenderness when chewing or brushing near the area.

Pain that improves day by day

Discomfort should peak within the first 48 hours and begin to fade after that.

Sensitivity to pressure

If you tap your tooth or bite down, you might notice some pressure sensitivity. That’s okay—as long as it’s getting better, not worse.

Easily controlled with OTC medications

Pain should be manageable with ibuprofen, acetaminophen, or whatever your provider recommended.

What’s NOT Normal? When to Call Your Dentist or Endodontist

Pain after a root canal should be short-lived. If you notice any of the following, don’t wait—call your provider right away:

Severe or throbbing pain that gets worse over time

This could indicate that the infection wasn’t fully removed or that there’s a complication in healing.

Pain that lasts longer than 5–7 days

Ongoing pain a week after your root canal is not typical. Something might need to be reevaluated.

Visible swelling in the face or jaw

Swelling could be a sign of a spreading infection and needs immediate attention.

Fever or chills

These symptoms suggest a systemic response and should be addressed promptly.

A return of pus or a bump on the gum

If you see drainage or a pimple-like spot reappear, the infection may not have been fully resolved.

What Might Be Causing Continued Pain?

Sometimes, even a well-performed root canal may leave you feeling less than perfect. Here are a few possible reasons:

Missed canals or complex anatomy

Some teeth have hidden or curved canals that are difficult to treat in one visit. A second treatment may be necessary.

High bite or dental trauma

If your bite feels “off” after the procedure, your tooth may be hitting too hard against others, causing pain. A quick adjustment can usually fix this.

Cracked tooth

A fracture that wasn’t visible before treatment may now be contributing to discomfort.

How to Manage Normal Root Canal Pain at Home

Most patients recover quickly without complications, and these simple tips can help ease the healing process:

  • Take all medications as directed

  • Avoid chewing on the treated side for a few days

  • Use a soft toothbrush

  • Apply a cold compress (20 minutes on, 20 minutes off)

  • Rest and give your body time to heal

What About the Crown?

If you haven’t had your permanent crown placed yet, your tooth is still vulnerable. Be careful with it until your general dentist completes the final restoration. A crown helps protect the tooth and prevent breakage.
