For complete oral care, brushing alone is not enough. Adding a 30-second rinse with Listerine Original Mouthwash to your morning and night time routines is all it takes to get 24 hour protection against germs that cause bad breath, plaque and gum disease gingivitis. It reaches areas of your mouth that toothbrush cannot reach. Listerine mouthwash comes from a formula of four essential oils that kill millions of germs on contact. The combination of eucalyptol, menthol, methyl salicylate, and thymol continues to deliver unsurpassed results. Moreover, Listerine Original Mouthwash has the Indian Dental Association Seal of Acceptance. To use, rinse full strength for 30 seconds with 20 ml (2/3 fluid ounce or 4 teaspoonfuls) morning and night. Do not swallow. Avoid rinsing the mouth with water or eat and drink for 30 minutes post rinse for maximum benefit. It is not suitable for children below 12 years of age. It comes in a 500ml bottle.
