CrestWhitening Emulsions Leave-on Teeth Whitening Gel Pen Kit, 0.88 Oz (25 G)

Started to see the difference in 2 days.. Great for wine and coffee drinkers.

Definitely works with consistent use!!

Easy to use, I just put a little bit on my finger and rub it on my teeth. Can control how much I use.

I was pleasantly surprised to see a difference the first time I used the product, but it doesn't last past the next meal. Still, it does give a temporary whitening.

Exactly as described. Seems very effectiveReally stays on your teeth which is awesome and don't have to use like a little tray

I have always believed Crest to be a superlative product. However, this product is absolutely useless for its purposes.It is a gel which DOES NOT stick to your teeth therefore even after you dry your teeth, as per package instructions, the gel does not stick to teeth as your natural saliva washes product away in seconds. No matter how many attempts I made, it was fruitless for product have enough time to be effective.It was a waste of $40.00 and extremely disappointed in the product.I have never written a review therefore this review tells you how disappointing the product was.

I’ve been using it once a day because I can’t be bothered to use it multiple times a day even though it says you can. There’s not much of a taste but it is a little minty. For me the whitening has been slow and I’m sure that’s because I’m only using it once per day however it’s not causing me any sensitivity which is always a big concern for me when it comes to whitening. I’ll most likely continue using this product because even if slow it is giving me results and there is 0 sensitivity afterwards.

This works much better than the whitening strips. Easy to use.
