What is one of the possible signs of a tooth abscess?

A tooth abscess is a localized collection of pus that can develop due to bacterial infection, often stemming from untreated dental cavities, gum disease, or trauma. One of the hallmark signs of a tooth abscess is a severe toothache, which is typically intense and persistent. This pain is often accompanied by swelling in the affected area, which occurs as the body responds to fight the infection. The swelling may be visible on the gums or face, and it indicates that there is inflammation occurring due to the infection in the tooth's pulp or surrounding tissues.

While sensitivity to hot and cold foods, bleeding gums, and persistent bad breath can be associated with various dental issues, they are not definitive indicators of a tooth abscess. Sensitivity often indicates other forms of dental problems, such as enamel erosion or gum sensitivity, rather than pinpointing an abscess. Similarly, bleeding gums is more commonly associated with periodontal disease rather than a localized abscess. Persistent bad breath can occur for a variety of reasons, including poor oral hygiene or other infections, and does not specifically indicate a tooth abscess. Therefore, the combination of severe toothache and swelling is a more accurate sign of this particular condition.
