Not all dental emergencies are life-threatening. With immediate treatment, untoward events can be prevented. However, if toothache, chipped teeth, and loose filling and crowns are ignored, they can lead to tooth decay and abscess formation due to bacterial infection. If a tooth abscess is not drained and stopped from progressing, the bacterial infection can spread to the brain or bloodstream. It can also lead to further swelling that blocks the airway. In cases like this, the spread of infection can be life-threatening and dangerous.
