Super white smile!
If you are looking to whiten and brighten your smile look no further. These are the best whitening strips on the market that do not require you to see a dentist. My teeth are so white and bright. I have sensitive teeth and these don’t seem to bother them either with recommended use. Highly recommend to everyone.

THE BEST TEETHING WHITENING EVER
These really do work! I had done these for three day and there a big different already. I suggest to buy this product and I think it’s worth your money. I will say though to be careful because they make your gums sensitive and can give your gums burn if you’re not careful. If you notice any burning of the gums please take a break so you don’t further damage your gums. Other than that this product is only teeth whitening treatment that didn’t put weird white patches on my teeth. So if you’re struggling with that, I suggest you buy these.

Popular for good reason!
All it took were 2 sessions before I noticed a brighter, whiter difference! They stayed on fine for the most part although for some reason the bottom strips wouldn't stick to the backs of my lower incisors as well. Also no issue with discomfort or sensitivity
