Has anyone experienced little bits of tissue or skin sloughing off in his/her mouth? It started shortly after my father died, so I assumed it was stress related. But in doing some research tonight, I learned that skin sloughing can be caused by sodium lauryl sulphate in some toothpastes. Checked my tube and realized it was a different product of Crest than I normally use. This one is Pro Health Advanced. I don't brush my cheeks and try not to get toothpaste anywhere but my tongue, so I'm not sure how any contact has occurred. Thoughts or similar experiences, anyone? There's no pain or bleeding.
