Which mouthwash is best for gum health and killing germs?

Healthy gingiva...: Healthy gingiva start with meticulous home care, brushing and flossing twice a day. Regular visits to your dentist (for most people twice a year) for professional hygiene visit and examination. Poor restorations and carious lesions should be restored. Periodontal issues should also be treated. Mouthwashes do just that.. they wash your mouth, but they are not a substitute for the above suggestions.
