Which constituent of mouthwash is commonly recommended by dentists for treating ANUG?

Chlorhexidine is the constituent of mouthwash that is commonly recommended by dentists for treating Acute Necrotizing Ulcerative Gingivitis (ANUG). This antimicrobial agent is effective in reducing harmful bacteria in the oral cavity, which is crucial for managing conditions like ANUG, characterized by ulcerative lesions and significant inflammation of the gingival tissues.

The benefits of chlorhexidine include its ability to disrupt the cell membranes of bacteria, thus reducing plaque formation and gingivitis. It also has a sustained antibacterial effect, meaning that it continues to act over an extended period after rinsing. The use of chlorhexidine is particularly important in the treatment of ANUG, as it helps in alleviating symptoms such as pain and swelling while promoting the healing of the affected tissues.

While hydrogen peroxide can be used as a mouth rinse in some contexts due to its effervescent properties and mild antiseptic effects, it does not have the same level of sustained antimicrobial action as chlorhexidine and is not specifically recommended for ANUG. Alcohol can sometimes irritate oral tissues and may not be suitable for patients with ANUG, while essential oils may not provide the same level of antibacterial efficacy required in the context of this condition.
