After about a week I actually notice a difference in the whiteness of my smile. Will continue to use for a month and update. I do notice though that rinsing with cold water after 2 mins of this stuff in my mouth really sharpens up the temporary sensitivity.
I only used for 3 weeks or so , once in the morning and once in the evening. I didnt notice any dramatic difference in my teeth, but I think there is a slight improvement. What i didnt like is how strong the taste was , it just hurt. I felt like the inside of my mouth had blisters. But as time went on, I think the mouth started to get used to it. I guess, no pain, no gain. Also to note, I don't use mouthwashes in general, so maybe this is normal strength but Im just not used to it.
I’ve always taken very good care of my teeth and recently wanted to giving this a try, as I’ve always had white teeth but it couldn’t hurt.
Boy, was I wrong. After about 2.5 weeks of using this, I noticed my teeth would really hurt when eating cold foods (yogurt in this case) and gums became receding to the point that I had to see a dentist (not fixable).
This isn’t a bad product but you should be aware that it can have some Side effects.
This caught me by surprise as soon as I started to swish it around in my mouth it started to expand like a foam I was not ready for that surprise, And you seem to spit lots of foam at the end. But I would say my teeth are a bit whiter...
Didn't really notice a shade difference. I have bright teeth but coffee stains, didn't change at all. It does taste good and gives a good aftertaste / breath. Won't buy it again, as it's better to just buy the toothpaste from crest and use it everyday as normal.
