Mouthwash can help reduce bacteria and soothe the area around a mouth bump, but it’s not a cure for the bump itself. If the bump is caused by an infection or inflammation, you might need a specific treatment depending on its cause. If the bump persists, worsens, or is painful, it's best to consult a dentist for an accurate diagnosis and appropriate treatment.
