Which class of conditions would most likely not need antibiotics?

Gingivitis is primarily characterized as an inflammation of the gums without the presence of underlying bacterial infection, especially in its early stages. It is often caused by plaque buildup on the teeth and is largely a reversible condition with proper oral hygiene practices, such as regular brushing, flossing, and professional cleanings. Antibiotics generally target active infections and are not necessary for treating gingivitis, as the condition can usually be managed effectively through non-invasive dental care and improved oral hygiene.

On the other hand, trauma-related dental procedures may involve risk of infection, while current infections would likely require antibiotics to address the underlying bacterial cause. Periodontal surgeries often involve manipulation of the gum tissue and bone, and may also necessitate antibiotic treatment to prevent post-surgical infections.
