The problem I had was figuring if a product had Sodium Lauryl Sulfate.
I found that if I wash my sheets with detergents with it, the first night my sheets make me feel like I'm sleeping with a sunburn.
Apparently toothpaste with SLS might cause canker sores.
It is deliberately hard to determine!
lol, here's a website:

they use different names on purpose.
Yup, stopped using SLS toothpaste because I heard that it could be causing my canker sores. I've had ONE in the three years since, when they were a weekly occurrence before.
