Review on 🦷 Crest 3D Supreme Flexfit Teeth Whitening Kit with White Whitestrips by Monica Kittling

The photos I have attached were taken ONE DAY apart. This product is crazy! This is after two white streaks, one at night and one the next morning (you should probably wait 24 hours but I was curious to see what would happen). I used these strips in combination with Crest 3D White toothpaste and mouthwash, in case that matters. The only side effects I've noticed so far are those disclosed by Crest, namely tooth sensitivity and mild gum discomfort. They say it's temporary, so I hope it's true. One thing I would like to say is that you have to be careful not to apply the strips too hard on the gums, it hurts a bit and can cause blanching (whitening of the gums) but this is temporary. Otherwise I am VERY SATISFIED with this product and will definitely be using all 21 strips. CREST DOES NOT SPONSOR ME IN ANY WAY, I JUST WANT ALL WHITE TEETH
