Why are antiviral agents used in treating herpetic gingivostomatitis?

• A. Antiviral agents target the viral infection, which is the cause of the condition.
• B. Antiviral agents kill bacteria that infect the mouth.
• C. Antiviral agents prevent dehydration.
• D. Antiviral agents are used to manage fever only.

Answer: (A)

Herpetic gingivostomatitis is caused by a herpes simplex virus, so treatment with antiviral agents targets the underlying viral infection rather than bacteria or purely symptomatic relief. These drugs interfere with viral replication, helping the immune system clear the infection faster and reducing how long the fever, mouth soreness, and lesions last. They’re most effective when started early, within the first day or two of symptoms. Antivirals don’t kill bacteria, so they won’t prevent bacterial infections; they also don’t directly prevent dehydration or act solely to reduce fever, which are managed with fluids and supportive care. Thus, the main reason for antiviral therapy is to combat the viral cause of the condition.
