5 Signs You Might Need a Root Canal

Root canals get a bad rep — but avoiding one when it’s needed can lead to serious damage. Here are five clear signs your tooth might be calling for help.

1. Persistent Pain .

If the pain lingers long after eating, drinking or even brushing — it’s not normal. Pain deep in the tooth often means infection has reached the nerve.

2.Sensitivity to Hot or Cold

A sharp, lingering sensation when sipping something hot or cold can indicate a damaged pulp inside the tooth — a classic root canal warning sign. ---

3. Swollen or Tender Gums

Inflamed gums near a specific tooth might suggest an infection or abscess, especially if it feels painful when touched. ---

4. Darkening of the Tooth

A tooth that suddenly turns greyish or dark may have dying tissue inside. This is a silent red flag that usually calls for a root canal.

5. A Pimple on the Gums

If you notice a small bump or pus-draining spot near the base of the tooth — that's often an abscess, and it's not something to ignore.
