Don't like the way my gums feel
I had never used a tooth whitener before, and when I painted this on my teeth, I immediately began feeling some burning in my gums. A friend of mine who uses these regularly said that was normal and nothing to worry about, but for me I don't think I can tolerate it. I can't say this is a bad product because I only used it once and it was easy enough to apply. But it is not for me.
