Review: Works But May Irritate Gums a Tiny Bit! - Bought this to try as it was a little cheaper than my Dentists of the same %strength. This worked better but was also a tiny bit irritating to my gums. Irritation was not bad at all as was gone between middle and end of next day. Irritation was only felt, gums a little deeper pink but nothing more. Will buy again when I run out. Note: I don’t bleach often, just every couple of months.
Review: Teeth whitening - Very easy to apply with pre-fabricated dental trays from my dentist office. Same product my dentist provided but cheaper. The product works as advertised whitening my teeth. Use once a month.

### ⭐⭐⭐⭐ Works if you stick with it.
*by L***Y on January 24, 2026*

Couldn’t really tell a difference. I didn’t really stick with it. But my younger sister tried it and her teeth look stunningly white. And she’s a smoker. I was shocked. They really do look stunning. We’re both in our 50’s.
