Root canals have a reputation for being scary, but they’re actually a routine way to save a tooth from extraction. Knowing the warning signs can help you get treatment before the problem gets worse.

Persistent or Severe Tooth Pain

One of the most common signs is ongoing pain, especially pain that worsens when you bite down or apply pressure. This often signals that decay or infection has reached the pulp inside the tooth.

Sensitivity to Hot and Cold

If hot or cold foods and drinks cause lingering pain that doesn’t go away quickly, it could mean the nerve inside your tooth is inflamed or infected.

Swelling and Tenderness

Swelling in the gums near a specific tooth, along with tenderness when touched, can indicate an infection that has spread beyond the tooth itself.

Discoloration and Other Signs

A tooth that has darkened or changed color, or one that keeps developing pimple-like bumps on the nearby gum, may also need root canal evaluation. Learn more about our root canal treatment and what to expect.

Frequently Asked Questions

How do I know if I need a root canal versus a filling?

A filling is typically enough for decay that hasn’t reached the tooth’s pulp. Once the pulp is affected, causing pain, sensitivity, or infection, a root canal is usually needed.

Is a root canal painful?

Modern root canal treatment is performed under local anesthesia and is generally no more uncomfortable than getting a filling.

What happens if I ignore the signs and skip treatment?

Untreated infection can spread, cause worsening pain, and ultimately lead to tooth loss.

Will I need a crown after my root canal?

Many teeth need a crown after root canal therapy to restore strength and protect against future fracture.

Can a root canal save a tooth that’s already infected?

Yes, in most cases root canal therapy can save an infected tooth by removing the infected pulp and sealing the tooth to prevent reinfection.
