  • Lingering pain after hot or cold.
  • Spontaneous pain, worse at night, radiating to the temple or ear.
  • Pain on biting.
  • Gum swelling, a pimple near the root, darkening tooth.

Painkillers only mask symptoms. Untreated pulp inflammation can lead to infection and facial swelling, making treatment more complex.

Note: Treatment indications and outcomes depend on each person's oral condition, general health and home care. This article is for general information only; an in-person examination is needed for individual advice.
