I've found that toothpaste and that includes all the expensive brands for sensitive teeth on down the line have basic soap in them. Who knew ? I sure didn't ! Not until I started having the very same problems many of the people have described like red burning tongue, gums and it travels out to the lips. Finally , I had to talk to our dentist and was told about soap being in toothpaste. While some didn't have it in the past and some had small amounts, according to him it has been increased and more people are having issues like us. Look for the ingredient called Sodium laurel sulfate when buying mouth products. I will say its getting more difficult to find any that doesn't have sls including Toms all natural, which never had it before but now I'm unable to find that brand w/o as well . I will be following these posts in hopes someone will have answers that help us soon because it's not pleasant and after a few weeks like this you can't enjoy even bland foods without quite a bit of pain. Good luck to all.
Thank you. I will look into it.
