I recommend TheraBreath mouthwash.

This is TheraBreath, the mouthwash I love to use!!

After brushing my teeth and gargling with TheraBreath before bed, my mouth felt clean and fresh the next morning.

It doesn't give me bad breath, and although the taste isn't great when I gargle, I use it well because it works well for me haha.

They say it was developed with a father's heart to get rid of his daughter's bad breath.

You can easily find it at Olive Young or supermarkets, and it is also sold on iHerb!
