                        Please try a toothpaste without Sodium Laurel Sulfate (SLS).  It has worked for my son.  He doesn't get the mouth sores any more.  We first read about this on the internet and bought a toothpaste Walgreens carries for dry mouth, which doesn't have this ingredient.  Or health food stores should have a least one toothpaste without SLS.  The Tooth and Gum Green Tea toothpaste is our favorite.
