It is believed that a strong salt solution is good to kill odor-producing bacteria in your mouth. I think it is a good alternative to commercial mouthwash I am not a fan of.
That sounds about right. Salt has many uses that a lot of people don't realize. But I agree with you on the mouthwash, I don't like the fact that it has alcohol in it.
I doubt it tastes yummy but I am sure it would work. The only issue I might see is if someone had an open cut in their mouth or maybe on their lips, the stinging would not be the best.
When I was a kid, I was very scared to see our family dentist. Even so, he extracted a rotten tooth from my mouth and allowed me to gargle saltwater to wash away the blood from my gum. It was warm and relaxing.
It's much better than the stinging mouthwash.
