I bit my gum and now it's swollen
A bitten gum may swell from a bruise or small wound, but worsening pain, pus, or fever needs dental assessment.
The short answer
A bitten gum usually becomes swollen because the gingival tissue was bruised or torn. Keep it clean, protect it from further trauma, and monitor how it changes.
What changes can occur inside an injured gum?
The injured area may contain a clot, abrasion, or laceration in the mucosa over the jaw. Swelling that spreads or intensifies can indicate infection or a deeper injury rather than simple healing.
How can you care for a swollen bitten gum?
Rinse gently with warm salt water, choose soft foods, and use a cold pack outside the cheek for short intervals. Do not pick the wound or place aspirin directly on the gum.
When should a dentist assess swelling after a bite?
See a dentist if the swelling worsens, remains painful, drains pus, or interferes with chewing. Seek urgent care for facial swelling, fever, uncontrolled bleeding, or difficulty swallowing or breathing.
What should the dentist check in the swollen tissue?
Ask whether the tissue is only traumatised or needs closure, cleaning, imaging, or treatment for an infected tooth nearby.
