For which dental condition is Metronidazole specifically given?

Metronidazole is specifically indicated for Acute Necrotizing Ulcerative Gingivitis (ANUG) due to its effectiveness against anaerobic bacteria commonly associated with this condition. ANUG is characterized by gingival ulceration, pain, and bleeding, often linked to poor oral hygiene and stress factors. The anaerobic microorganisms involved in ANUG respond well to Metronidazole, making it a suitable treatment option.

While Metronidazole can also be used in other dental conditions like periodontal disease and dental abscesses, its primary association is with ANUG, where it helps reduce inflammation and fight the specific pathogens involved. In contrast, tooth decay, primarily caused by cariogenic bacteria, would typically be managed with different approaches, including restorative dentistry and oral hygiene interventions rather than antibiotic therapy.
