When it comes to oral care, it's Garglin.

I use this mouthwash because it is the mildest and most effective among all the mouthwashes I have. It is dye-free and doesn't have an overly strong tingling sensation, so even if I accidentally swallow it, it doesn't feel unpleasant. It is great to use before and after brushing, so I recommend this Gargrin to many people around me. Since it is mild, it is good for frequent use, so I always keep it nearby and gargle whenever I have free time; as a result, I don't have to worry about bad breath.
