How to reduce swelling from a toothache
Toothache swelling needs dental assessment because cold compresses and pain relief may ease symptoms without treating the underlying cause.
The short answer
Use a cold pack against the cheek, keep the head raised, rinse gently with warm salt water, and arrange urgent dental care. Swelling can come from inflammation or infection around the tooth or gum.

What is the direct answer?
What does this question mean?
Swelling beside a painful tooth can involve the pulp, root tissues, gum, or a space around the tooth. Decay, a cracked tooth, gum disease, food trapped under the gum, or an abscess can produce this pattern.
What can you do next?
Apply a wrapped cold pack outside the cheek for short periods, drink water, brush gently, and take an over-the-counter pain medicine only if its label and your health history allow it. Do not squeeze the swelling or put heat directly on it.
When should you seek dental care?
Contact a dentist promptly when swelling accompanies toothache, returns after pain medicine wears off, or spreads into the cheek or jaw. Seek emergency medical help for trouble breathing, swallowing, speaking, or opening the mouth.
What should you ask the dentist?
Ask whether the swelling is from the pulp, gum, or an abscess, whether imaging is needed, and whether treatment involves drainage, a filling, root canal treatment, extraction, or periodontal care.
Frequently asked questions
Can salt water cure a tooth infection?
A gentle rinse can clean the mouth and soothe irritated tissue, but it does not remove infected pulp or drain an abscess.
Should I put ice directly on my gum?
No. Wrap the cold pack and place it on the outside of the cheek to protect the skin and oral tissues.
