Comment on YSK that SLS, an ingredient added to most commercial toothpastes, causes canker sores

I’ve always thought I was mildly allergic to some brands of toothpaste, wonder if this was related.

My symptoms were sores in the corners of my mouth/gums - took a couple weeks before they’d show up and the only way to get them to go away was heavy rinsing with water after brushing (which is not recommended because of fluoride mineralization)

Switched to Tom’s toothpaste (with fluoride) a few years ago and have had 0 issues since
