Here's how to take the LISTERINE® 21 Day Challenge

Pick the LISTERINE® Total Care mouthwash that suits you best. LISTERINE® Total Care is our most advanced and complete Listerine mouthwash. Total Care Zero has no alcohol therefore is less intense and has a milder taste.

Use your chosen LISTERINE® Total Care mouthwash to clean your mouth beyond brushing, morning and evening for 21 days. By adding LISTERINE® Total Care into your oral care routine, we think you'll love the transformation in how your mouth feels.

Mouthwash tips

Keep your LISTERINE® in a visible place (out of reach of children) in your bathroom to remind yourself to use it twice a day. Count to 30 while rinsing to give your whole mouth that clean, fresh feeling.

Why twice a day?

In order to get the full benefits from your chosen LISTERINE® Total Care mouthwash, use it twice a day for a deep clean and up to 24 hour fresh breath protection.

Why 21 days?

New habits are formed through repetition, and by using LISTERINE® morning and evening for 21 days, you will use the mouthwash over 40 times, after which mouthwash may become a regular part of your daily oral care routine.
