How to reduce swelling due to toothache
Cold compresses and suitable pain relief can ease swelling, but a dental infection needs treatment of its source.
The short answer
To reduce toothache-related swelling, use a cold compress on the cheek, keep your head raised, and use suitable pain relief according to its label or your clinician’s instructions. These measures can ease symptoms, but swelling from a dental infection needs treatment of the tooth or gum source.

What is the direct answer?
What does this question mean?
Toothache swelling is usually inflammation in the gum or tissues around a tooth, sometimes caused by decay reaching the pulp, a root infection, gum disease, or an impacted tooth. Pus may collect in a confined space and create pressure in the gum, cheek, or jaw.
What can you do next?
Rinse gently with warm salt water if it is comfortable, keep brushing carefully, and avoid placing aspirin, concentrated peroxide, or heat directly on the gum. Arrange dental care promptly because drainage, a filling, root canal treatment, extraction, or periodontal treatment may be needed depending on the examination.
When should you seek dental care?
Get emergency help if swelling spreads toward the eye or neck, or if you have fever, trouble swallowing, trouble breathing, or difficulty opening your mouth. Even smaller swelling should be assessed soon, especially when pain is severe or the tooth is sensitive to biting.
What should you ask the dentist?
Ask which tooth or tissue is causing the swelling, whether an X-ray is needed, and what treatment will remove the source. Ask which pain medicines fit your medical history and what changes mean you should seek emergency care.
