I was told by experts at a dental school over 20 years ago that asprin (salicylic acid) will damage gum tissue.
They also told me that baking soda, salt, peroxide mixture was not good for my teeth and gums.
I figured that they were probably correct about the asprin and stopped using it. However, I did not listen to them when it came to the baking soda mixture.
I'm with you. As far as I'm concerned, it Op for me.
