A tooth infection can become life-threatening if left untreated, as bacteria can spread from the infection site to other parts of the body. However, it typically takes weeks or months for an infection to reach a dangerous stage.

Symptoms Indicating Urgent Care is Needed

Severe pain that doesn’t subside
Swelling in the face, neck, or jaw
Fever or chills
Difficulty breathing or swallowing

If these symptoms appear, seek immediate medical attention. While it is rare for a tooth infection to be fatal, prompt treatment with antibiotics or dental procedures can prevent the infection from spreading to other critical areas of the body, such as the brain or heart.
