Signs You May Need a Root Canal

Warning signs that could mean the inside of your tooth needs attention

A toothache doesn’t always mean you need a root canal treatment. However, certain symptoms can indicate that the soft tissue inside a tooth, known as the pulp, has become inflamed or infected.

At New Era Dentist in Maple Ridge, evaluating persistent tooth pain, sensitivity, swelling, or other changes can help determine whether the problem involves the tooth’s nerve and whether endodontic treatment may be appropriate.

Understanding the warning signs can help you know when it’s time to have a tooth examined.

1. Tooth Pain That Doesn’t Go Away

Persistent tooth pain is one of the most common reasons people seek dental care.

Pain associated with an infected tooth may be constant, or it may come and go. It can sometimes become more noticeable when biting, chewing, or putting pressure on the tooth.

Not every toothache requires a root canal, but pain that continues or becomes worse should be evaluated rather than ignored.

2. Lingering Sensitivity to Hot or Cold

It’s normal to occasionally experience brief tooth sensitivity. The concern is when the discomfort lasts well after the hot coffee, cold drink, or food has been removed.

Lingering sensitivity can sometimes indicate inflammation or damage inside the tooth.

If a particular tooth suddenly becomes much more sensitive than the surrounding teeth, a dental examination can help identify the cause.

3. Pain When Biting or Chewing

Does one tooth hurt every time you bite down?

Pain under pressure can have several possible causes, including a crack, decay, a damaged restoration, or inflammation around the root of the tooth.

Because these conditions can feel similar, an examination and dental X-rays may be needed to determine whether root canal treatment is necessary.

4. Swollen or Tender Gums

A tooth infection doesn’t always cause severe tooth pain. Sometimes the first noticeable sign is swelling or tenderness in the gum near the affected tooth.

You may notice:

• Localized gum swelling
• Tenderness around one tooth
• A small bump or pimple on the gum
• An unpleasant taste or drainage

These symptoms should be assessed by a dentist, particularly if they persist or return.

5. A Tooth Becoming Darker

A tooth that gradually turns grey or darker than neighbouring teeth can sometimes indicate damage to the pulp.

This may happen after trauma, even if the original injury occurred months or years earlier.

Discolouration alone doesn’t automatically mean you need a root canal, but a noticeable change in one tooth is worth discussing with your dentist.

Why Would a Tooth Need Root Canal Treatment?

Inside every tooth is a space containing nerves, blood vessels, and connective tissue. Deep decay, cracks, trauma, or other damage can allow this tissue to become inflamed or infected.

During endodontic treatment, the affected tissue is removed, the inside of the tooth is cleaned and disinfected, and the space is sealed.

The goal is to address the infection or inflammation while preserving as much of your natural tooth as possible.

Can a Tooth Infection Go Away on Its Own?

Symptoms can sometimes temporarily improve, but that doesn’t necessarily mean the underlying problem has resolved.

For example, pain may decrease if the nerve inside the tooth becomes severely damaged. An untreated infection can still remain around the root and surrounding tissues.

That is why changes in symptoms shouldn’t be used as the only indication that the tooth has healed.

Frequently Asked Questions

Is severe pain always a sign that I need a root canal?

No. Tooth pain can result from cavities, cracks, gum problems, grinding, sensitivity, and other conditions. A dental examination is needed to determine the cause.

Can I need a root canal even if my tooth doesn’t hurt?

Yes. Some teeth with damaged or infected pulp may cause little or no pain. Changes seen on an X-ray, swelling, discolouration, or other symptoms may reveal the problem.

Does a root canal remove the tooth?

No. Root canal treatment is designed to preserve the natural tooth by treating the tissue inside it.

What happens after a root canal?

Depending on the tooth and how much structure remains, a restoration such as a filling or dental crown may be recommended to protect and restore the tooth.

When should I contact a dentist about tooth pain?

Persistent or worsening pain, swelling, prolonged sensitivity, or pain when biting should be assessed. Significant facial swelling or symptoms such as fever should be addressed promptly.
