For a year I had a huge toothpaste problem. Lips swelled, sores on my tongue edges, red inflamed area around my mouth( Dr no help.)Tried MANY toothpastes, all burned so bad I finally only brushed with baking soda. Which worked but wanted better for mouth and teeth. This is working, no burning, no swelling, teeth and mouth feel great, clean, I would love to get the mint but afraid it might start everything up again. For me Pearl Teethpaste is a huge deal.
