I stopped getting canker sores some years ago after changing toothpastes. Having read of SLS, I assumed that was the culprit — but no, I read the ingredients and my new "good" toothpaste also has SLS. So whatever the change was, that wasn't it. For all I know it wasn't even the toothpaste at all!

Interesting. Could have also been a concentration thing, if the newer one just had less of it. But yeah, could potentially have been something else completely!
