Yes, tooth pain can go away by itself in some cases. Tooth pain is usually caused by inflammation in the tooth, which can be caused by things like gum disease, cavities, and tooth decay. In some cases, the inflammation can subside on its own, leading to the pain going away.
In other cases, however, the pain may persist and require medical treatment. Some of the more common treatments for tooth pain include antibiotics to treat an infection, a filling to seal off a cavity, or a root canal to save a damaged or dying tooth. In these cases, the pain will not go away until the underlying issue is addressed.
It is important to note that tooth pain should never be ignored, even if it seems to go away on its own. This could be a sign that there is an underlying issue that needs to be addressed before it worsens. If you are experiencing tooth pain, it is best to see a dentist as soon as possible to get an exam and diagnosis.
