I bough this product over a month ago and gave it to my son who’s a heavy smoker. His teeth were yellowing and had stains from to tobacco forming where he held his cigarette. After only three days his teeth were noticeably whiter. After 7 days the tartar stains were greatly diminished. He’s loving his new smile. I also purchased a toothbrush to help with his overall oral health.

these strips changed my entire life. my teeth used to be YELLOW they are now as white as computer paper. every 6 months I get a new box even though I don't actually have too. your teeth will stay pretty much white for probably over two years. I like how they look right after or during a box because they are sparkling. if I could post pictures I would. awesome.

I drink coffee, plenty of caffeine, and used to drink a lot of red wine. I have used crest white strips for something close to a decade. For a while I will use them once a week and then for one reason or another I'll fall off my self care and forget to do them or run out and not be able to afford more. However I ALWAYS end up coming back to these. I have had my teeth professionally whitened at the dentist and that was extremely expensive and the sensitivity I experience afterward was not even worth it. My teeth were definitely very white but as I just said the pain and sensitivity made it not worth it. I use these once a week every week and I absolutely see a difference in the shade of my enamel and I have zero sensitivit

I love all crest products but honestly this one is deep inside my heart I started using this at 14 years old when I wanted my teeth a little more white, it’s been 5 years and I still use it until this day. It works wonders and after two treatments you will already see the results and you really won’t even believe it because I know I didn’t. Really a great great product.

This product truly works. I was skeptical about until my husband purchased it and told me to try it. I notice three days after using the stop. It did leave my teeth feeling a little sensitive but I left my teeth whiter than white! I highly recommend these strip if you want white teeth .

My teeth weren't very yellow to start with so I thought they would work relatively well as my boyfriend used them and his are very white. I finished my 20 days last night and took an after picture to compare with before using the same lighting conditions. There is no visible change, however my boyfriend thinks they're whiter. I think they're brighter and lighter but a light cream colour. My eyes are white and my teeth are yellow

I love Crest 3D White Luxe Professional fact Whitestrips! They show amazing results. My teeth look significantly whiter after using this. Once you get to the level of white you want, you don't have to whiten as often. I only whiten my teeth once a month now. They can make your teeth a bit sore if you have sensitive teeth so I recommend whitening before bed to help with the sensitivity and stay away from super cold food the first day after whitening.

This product works wonders on your teeth! However- the taste when you get it in your mouth is awful and causes me to spit a lot! Make sure you Pat your teeth dry to help it stick on. I always take Tylenol before hand and use a topocol numb gel because it makes my teeth and gums very sensitive. I reccomend right before bed so you don’t spend all day achy!!!

Not bad. I think my teeth got marginally whiter after using a box of white strips but it doesn't necessarily last for so long nor am I amazed with the difference. They are pretty expensive and also wearing them is not great either. They leave a gunky plastic taste in your mouth and it's hard to speak and swallow the 30 mins or so you have to keep them on

So basically a bad depressive episode caused me to neglect my teeth and then endless amounts of coffee didn’t help. After working myself out of it and finally taking care of myself, I still couldn’t smile with my teeth. I was self-conscious. I thought about getting them professionally whitened but opted to try this. BOY. I saw results by the third day like the box said I would. By the fourth day, I could almost cry. I’m not done with my 20 treatments yet but this has seriously changed everything. It makes me so happy. I can’t believe I could have just done this the whole time. Thank you crest, for this lovely product and giving me my smile back.
