I’m sure Crest is everything it says it is, and I have family members who prefer Crest. I used it for years, so I thought the peeling of my mouth tissue after brushing was normal! Turns out, it’s not. I shopped around and used several brands until I found the ONE brand that doesn’t affect me that way. I’m not sure if I should mention which brand I use, so I won’t. I’ve actually met other people who have the same reaction to some toothpaste brands.
