[Purchased with my own money] Pieras Pro Mouthwash

Of all the hospitals, the dentist is the scariest and most unpleasant, so I use mouthwash after brushing my teeth. It's 600ml, so it's really big, and since it contains liquid, it's a bit heavy—to be honest. It's a brown liquid, and after gargling, leftover debris comes out. At first, I wondered if I hadn't brushed properly, but I suspect the ingredients in the mouth are reacting in some way to make it look like debris. Just my guess.

My mouth definitely feels clean after using it. When I woke up in the morning, my breath didn't smell as bad as it did before, so I think this might be the reason.
