@pnlees I appreciate that. Also I should,mention that as a result of my whole tongue cancer ordeal I wound up with an allergy to mint. Any toothpaste or fluoride treatment, candy, gum, anything mint causes all of my mouth surfaces to swell up in pain! My fluoride treatment is now a children's fruit flavor....yuck! Early on I was able to use Xylimelts mints overnight...then one night my mouth, tongue and throat swelled up. Since then even a small amount of mint toothpaste creates havoc.
