What are signs you need a root canal?
Lingering pain, swelling, and temperature sensitivity can signal infected pulp. Know the warning signs early.
What are signs you need a root canal
Common signs you may need a root canal include lingering pain to hot or cold, spontaneous throbbing, pain when biting, gum swelling or a pimple-like bump near the tooth, and darkening of the tooth. Some infected teeth cause little pain and are found on X-rays.
These symptoms suggest the pulp inside the tooth is inflamed or dying, often from deep decay, a crack, or trauma. Only an exam with testing and radiographs can confirm the diagnosis. Waiting until pain is unbearable can allow an abscess to form and make treatment more urgent.

Key Points
- Temperature sensitivity that lingers for minutes—not seconds—is a classic pulp warning sign.
- Nighttime throbbing or pain that wakes you often points to irreversible pulpitis.
- Swelling, a bad taste, or a draining bump on the gum can mean an abscess needing prompt care.
- A tooth that suddenly stops hurting is not always healing; the nerve may have died while infection continues.
- Deep cavities, large fillings, or cracked teeth raise your risk even before severe symptoms appear.
What This Means for You
Do not wait for unbearable pain. If you notice lingering sensitivity, bite pain, or gum swelling, schedule an exam soon so infection can be treated before it spreads.
