Can a toothache go away on its own?

Tooth pain can go away on its own in rare situations. For example, if you have injured gums from biting into something hard, your discomfort will likely go away in a day or two. But a true toothache — pain that originates from the tooth itself — usually means you have an issue that needs dental treatment.
If you have a toothache — whether it comes and goes or lingers — you should see a dentist as soon as possible. Treating the issue early can keep it from getting worse or causing more pain.
