Twice Teeth Whitening Strips, Enamel Safe, Slip Free, Value Pack - 40 Strips, 20 Treatments

Tried these and Crest Strips. I like these more because they have more teeth coverage, you get more in a pack, and they stay in place better. They don't hurt my teeth but the Crest Strips didn't either. Have noticed whitening after a 2-3 days but also started day after going to the dentist. Worth a try.

this product works and does not hurt my teeth

Love my results. I ordered a new box for a second cycle

This works really well and it's good for the sensitive teeth. Also, it doesn't slip and slide all over, just staying in place .

Wow! These are my new Holy Grail whitening strips. i always used abother brand of more expensive strips that worked, but did not stay on as well. Twice are doing the job and grip well too. No problem with sensitivity either. Have been using daily for five days now and my teeth are white. I always say that crooked white teeth look better than crooked stained teeth. i hate i did not take a before picture. but I also shy away feom pictores especially of my teeth! I do use a whitening toothpaste as well, so that helps some too.

I usually use the Colgate strips from Costco because of price but decided to try these after seeing them on tik tok and they really are so much better! My gums usually burn with the Colgate strips so I have to be careful when placing them. These ones don't burn at all and they almost taste a little sweet. I whiten my teeth routinely so they weren't super yellow to begin with but I visibly saw a big difference after just one treatment. The only con, if you can even call it that, is that once you pull them off a lot of residue is left on your teeth but the instructions say to just use a toothbrush to brush it off and since it doesn't taste bad I truly don't mind. It's a holy grail and I'll never go back to Colgate again!

These whitening strips have coconut oil %26 peroxide but do not make my teeth sensitive. I like them because they are stiffer than others I've tried making them easier to place. (I use a uv light with them also.) They do make my teeth whiter with regular use. However, I have yet to find any product that completely whitens the slight yellowing of my teeth at the gum line.

I really like these whitening strips. The do not slip around while you wear them. They work fast, I noticed a difference in just a few days. They do not cause any sensitivity either! Also, you get 20 treatments for $35!!! That is double the treatments for less than the other brands!

Strips were ok initially. Did whiten teeth but it only lasted for a week. Asked about refund because twice had a 30 day guarantee and they never would respond to emails. After months they finally respond and said out of their hands.

Did not help. Left white spots on teeth.
