Call 911 or go to the ER for these signs
Some dental problems are medical emergencies. Get emergency care right away if you have:
- Difficulty breathing or swallowing
- Swelling of the face, jaw, floor of the mouth, or neck — especially if it is spreading
- Swelling that affects your eye or makes it hard to open your mouth
- A high fever combined with mouth or facial swelling
- Bleeding that won't stop after 10–15 minutes of firm pressure
- A knocked-out adult tooth, or an injury to the jaw, head, or face
When in doubt, consider it an emergency and seek care now.
A severe or lasting toothache is your body signaling that something — often a cavity, a crack, or an infection — needs professional attention. The tips below are general comfort measures to use while you arrange care. They are educational information, not a diagnosis, and they don’t replace seeing a licensed dentist.
What to do now
- Rinse with warm salt water (about half a teaspoon of salt in a cup of warm water) to clean the area and soothe the gum.
- Floss gently around the sore tooth to dislodge any trapped food, which can sometimes be the trigger.
- Use over-the-counter pain relief as directed on the label. Take it by mouth — never place a tablet directly against the gum or tooth.
- Apply a cold compress to the outside of your cheek for swelling or throbbing.
- Arrange to see a dentist promptly, especially if the pain is severe, wakes you at night, or lasts more than a day or two.
What the pain might be telling you
Tooth pain has many causes — decay, a cracked or chipped tooth, a loose filling, gum problems, or an infection near the root. Some are minor and some are not, and they can look similar from the outside. That’s why home measures are for comfort only: a dentist needs to find the cause and treat it. Pain that eases on its own doesn’t always mean the problem is gone.

Frequently asked questions
How can I relieve a toothache at home before I see a dentist?
General comfort measures include rinsing with warm salt water, gently flossing to remove any trapped food, and using over-the-counter pain relief as directed on the label. A cold compress on the outside of the cheek can ease swelling. These steps may make you more comfortable, but they don't treat the cause — see a dentist.
Should I put a painkiller tablet directly on the sore tooth or gum?
No. Placing pain-reliever tablets directly against the gum can burn the tissue. Take pain relievers by mouth as directed on the package instead, and check with a pharmacist or clinician if you're unsure.
When is a toothache an emergency?
Most toothaches are urgent but not life-threatening. Treat it as an emergency and seek immediate care if you have trouble breathing or swallowing, swelling spreading across your face or neck, a high fever with mouth swelling, or uncontrolled bleeding.
