Which is better mouth wash or salt water?

As I can not afford 2week vacation, he suggested to rinse with mouth wash3% pottassium nitrate and 0.2%sodium flouride. I feel more sweet wile rinse. Alternatively I used salt water to rinse.

Commercial mouth wash can have preventive ingredients --- to prevent gum disease aka pie-o-re-a inflammation of the gums

So for a last resort use salt solution when needed

warm water with a bit of salt is the better alternative. it is slightly similar with the body fluids so it won't do anything harsh.
mouthwash it has more ingrediants to help treat problems like that.
