5 Signs You Might Need a Root Canal

September 2, 2026 · By Dr. Sarah Bennett, DDS

Tooth pain that lingers after eating something hot or cold, pain that wakes you up at night, or a tooth that's become sensitive to pressure are all signs worth getting checked out promptly.

1. Persistent or throbbing pain. 2. Sensitivity to hot and cold that lingers. 3. Swollen or tender gums near a specific tooth. 4. A tooth that's darkened in color. 5. A recurring pimple-like bump on the gums.

If you're noticing any of these symptoms, don't wait — call our office. Catching an infection early almost always means a simpler, less costly treatment.
