7 Signs You Might Need a Root Canal (And When to Worry)

Lingering sensitivity to hot or cold that persists well after the stimulus is removed, spontaneous throbbing pain, swelling or tenderness in the gums, a darkening tooth, and a recurring pimple-like bump on the gum are all classic signs of pulp infection that a root canal treats.

Untreated pulp infection doesn't resolve on its own — it spreads, potentially leading to abscess, bone loss around the tooth root, and eventually tooth loss. What starts as a routine root canal can become a more invasive extraction and implant if left untreated for months.

If you notice any combination of these symptoms, book a same-day exam. Digital X-rays can confirm pulp involvement within minutes, and modern microscope-guided treatment resolves the infection with minimal discomfort.
