Can a Tooth Infection Go Away on Its Own?
Short answer: no. The pain from a dental infection can come and go, but the infection itself does not heal without treatment. Here is why, what to watch for, and what you can do now.
Why the pain can fade but the infection stays
- The nerve inside the tooth may have died, so you stop feeling it.
- Pus may drain through the gum, easing pressure for a short time.
- The cause, usually decay, a crack or gum disease, is still there, so the infection often returns.
Risks of waiting
An untreated dental infection can spread to the jaw, face or neck. Rarely, it can become serious. Getting it treated early is simpler and safer.
Get urgent help if you have
- Swelling spreading to your eye or neck
- Difficulty breathing or swallowing
- A high temperature or you feel very unwell

What to do now
- Book a dentist appointment as soon as you can.

Can a tooth infection go away on its own?
No. Pain may ease for a while, but a dental infection does not heal by itself. The cause, such as decay or a damaged nerve, stays in place and the infection can return or spread. A dentist needs to treat it.
Why has my tooth pain suddenly stopped?
Pain can stop if the nerve inside the tooth has died or if pus has drained. This does not mean the infection has cleared. You should still see a dentist.
What can I do until I see a dentist?
Take over-the-counter painkillers as directed on the pack, avoid very hot, cold or sugary food, use a soft toothbrush, and rinse with warm salty water. If you cannot get a dental appointment quickly, a clinician can assess whether interim prescription treatment is suitable.
