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

I use an SLS toothpaste and have never had canker sores but I agree it seems silly to add it when even a small dab of toothpaste creates an unnecessary amount of foam with proper brushing.

They come from a virus most people have living dormant inside them. Various factors may increase the breakout rate, but the virus is the true source. Sounds like you’re one of the lucky few uninfected.

You’re thinking of cold sores, I think OP just means mouth ulcers. I’m not sure what the word canker means, could be an American term.
