There are times when it is difficult to brush your teeth, or when you still feel a bit unsatisfied even after brushing. In those situations, I tend to use mouthwash frequently. However, some mouthwashes have colors that are too intense—blue or orange—which made me hesitant to use them. But Gargrin Zero has a mild mint scent and is transparent, so it is very pleasant to gargle with without any irritation or aversion. I recommend it because it is great for preventing cavities, removing plaque, eliminating bad breath, and preventing gingivitis.
