This is a post I wrote a few months ago:
I found that my toothpaste (design for sensitive gums) that had a whitening feature might be a source of irritation. I switched to a brand called Happy Tooth and have not has a flare in 3 months…I also avoid acidic foods and anything spicy…
Now it has been over 6 months with out a flare! I buy Happy Tooth on AMAZON...I ate super spicy food recently and my gums were OK but I won't chance that again...my stomach was very unhappy!
As far as other symptoms, I have a few other AutoImmune issues and Mast Cell Activation Syndrome, which is a pain to get under control.
