I have discovered a cure for sore throat or sore gums.
I just put a lot of salt into hot water and gargle then swish it around my teeth. It almost always works. One time it didn’t work and the dr. told me he was surprised that it didn’t.
He then gave me a prescription for a stronger than average anti-biotic.
I do the same thing except i gargle and spit
My late mother swore by salt for all mouth problems.
I continued that treatment with my own family.
My grandaughter just had cankers and swished the salt water around her mouth and they went away in a day.
Sometimes the old treatments are the best.
