How to reduce swelling from tooth pain

Cold compresses and gentle rinsing may ease dental swelling briefly, but swelling needs prompt assessment because infection may be present.

Dental swelling is inflammatory fluid around a tooth or gum, often caused by infection.

Rinse gently with warm salt water, keep the area clean, and use a cold compress through cloth. Do not put aspirin on the gum.

Seek urgent care for increasing swelling, fever, drainage, trouble opening the mouth, or pain that persists. Airway symptoms are an emergency.

Ask which tooth or tissue is infected and whether drainage, root canal treatment, or another procedure is needed.
