The intensity of pain is only one part of urgency. A small-looking injury can involve deeper damage, while swelling may need attention even before severe pain develops. Consider the overall picture, including fever, recent trauma, bleeding, and changes in your ability to open your mouth or swallow.
Lingering sensitivity or pain when biting
Brief sensitivity and lingering pain can have different causes. Record whether discomfort stops when a trigger is removed or continues afterward. Pain on biting, pain that wakes you, or symptoms that are worsening merit a dental assessment. Avoid testing the tooth with hard food to see whether it still hurts.
Tender gums, drainage or a new swelling
A gum bump, pus or facial swelling can be a sign of infection. Seek prompt professional attention, especially if you also feel feverish or unwell. Do not puncture the area. Spreading swelling toward the neck or eye, or difficulty swallowing or breathing, requires emergency medical care.
Pain following recent dental work
Contact the treating dentist when possible and explain the procedure date and symptom changes. Discomfort that increases, a bite that suddenly feels uneven, or new swelling deserves discussion. Do not alter the tooth or restoration yourself, and do not change prescribed medicines without advice from the prescribing clinician.
Trauma involving more than a tooth
After a fall, collision or blow to the face, consider possible head or jaw injuries as well as tooth damage. Loss of consciousness, confusion, a suspected broken jaw, or severe uncontrolled bleeding calls for emergency medical assessment. A dental appointment should not delay evaluation of those injuries.
