A toothache can be easy to put off, especially when the pain comes and goes. Some people wait because the discomfort seems manageable, while others assume the problem will eventually settle down on its own. Unfortunately, an infection inside a tooth does not simply disappear without treatment.

One of the most important questions patients ask is, can a tooth infection spread? The answer is yes. An infection that begins inside or around a tooth can extend into the surrounding gums, jawbone, and nearby tissues when left untreated. In more serious situations, dental infections can spread beyond the immediate area and become a significant health concern.

Understanding how infections develop and recognizing the warning signs can help patients seek care before the problem becomes more complicated.
