Pour in one capful, then rinse and gargle for 30 seconds after you finish brushing your teeth in the morning and evening.

BuzzFeed Shopping writer Amber Usher swears by this brand (especially the mint flavor): “I’ve been using this mouthwash for years and it’s changed my morning routine for the better. Not only does it eliminate morning bad breath, it’s also supposed to prevent gum disease. And I love the smell/taste – it’s like you just bit into a peppermint patty.”

Promising review: “This product changed my life! In my 30s I developed tonsil stones that caused very, very bad breath. My husband and kids often reminded me how unpleasant it was. I tried brushing my teeth more often, flossing more, using water flossers, and using the regular alcohol-based mouthwash twice a day. None of it helped. Finally I heard about TheraBreath and tried it. Problem solved!

“I gargled the first night I got it, went to bed, and when I woke up my husband and I couldn’t believe there was no smell. We were both shocked at how great this product is. The smell has completely disappeared. I have been using it morning and night for over a month now and continue to have fresh breath with no odor at all. I would 1,000% recommend it to anyone with similar problems.” – Latoya
