Did very little to whiten my teeth but made them extremely sore for about 2 days. Using these was the WORST idea I've ever had. I couldn't eat, drink or sleep for 2 days until the pain went away..... And my teeth weren't even noticeably whiter.
Fantastic results with little to no sensitivity but you have to use and re-use a few times per year. I had "Zoom" Whitening in a dentists office and was SO sensitive for 2 days afterward it was awful - and I only gained 2-3 shades.
With these I get about 1-2 shades whiter but it is less expensive and no pain.
This product summed up in one sentence: it works, but it hurts. I'm a coffee addict, so over time my teeth get quite yellow. This stuff really does give you professional teeth whitening results for a fraction of the price. I saw results after my first usage, and once I finish a pack, my teeth are dazzling. However, they can make my teeth SO sensitive. It's rather unpredictable; some days I'm fine, others I wake up in so much pain I can't eat anything. The pain does subside after a while. The adage "beauty is pain" really rings true in this case.
Usually this product is flawless for me. I have white teeth anyway and figured that it couldn't hurt to add a little white boost. It has always worked perfectly for me, and I've been using them for over a year, until today! I used the white strips as I usually do and as directed and left them on for the two hour express whitening. After I took them off, I had so much pain and soreness that I couldn't talk for hours, I thought my teeth would fall off. I don't know what I did wrong this time, but I definitely won't be using it again. It works but apparently beauty is still pain.
works! using x1 a year. tons complents. my mom also used. HUGE difference on her teeth (huge). mine were always kinda white to start. drink tons coffee and red vino. these keep my pearls white :). worth it. purchased new flex type only because that is all the store had. $58.00 so those better work or I'll be calling the 1 800 number and getting a full refund. that's the good news :) yes my teeth do get super sensitive sometimes it even hurts when I'm breathing in with the cold air. However that goes away within 2 days and much worth the compliments I get which are frequent. Its crazy. everytime I go to the dentist he asked me if I bleach my teeth and I say I do with the over the counter. I tell him the truth only maybe one time a year at most. He said that's fine no worries for my safety of the keys. 1 see your pretty much works for me even though I often fall asleep with a little red wine on my teeth haha
These WORK and are great if you have strong teeth; if your enamel is weakened it might hurt and you can feel the nerves inside your teeth sort of "sting you" and it hurts like hell... Tip*use sensodyne few days up until you use the strips, that's what I did and it really helps :) 5!stars though, these really work
I HATE this product. I followed the directions word for word, making sure everything goes correctly, right? WRONG. After I took off these strips, they created dreadful white spots on the bottom of each tooth. They also made my teeth sore for 4 days! DO NOT WASTE YOUR MONEY!
I have been using white strips even since they first came out, and these are by far the gold standard. How good are they? I recently "work traded" my industry skill with that of a dentist. I got a cleaning, x-rays, and Zoom Whitening treatment in exchange for the training skills I gave him. When the technician went to start the Zoom process, she used the plastic "sample teeth" to compare my teeth to the various levels of whiteness on the sample ones. My teeth were already at a Level 1 Bleach! Essentially, other than getting in the cracks a little bit more, my teeth can't get any whiter even with a system like Zoom that costs hundreds of dollars per treatment. I have tried all of the Crest whitestrips that came before these, as well as several others brands, as well as both store brand and custom made trays. This product kicks all of their butts. The whitening is intense and the strips absolutely do not budge. (It helps to dry your teeth off with a paper towel before applying and don't eat/drink while using.) In fact, the first time I tried to get these off, I freaked out a little: they were really stuck on! I will take that any day over the strips falling off. Another tip is to make sure you fold over the bottom of the strip to cover the back of your teeth, because teeth are semi-transluscent and do have stains on both sides. I also keep toothpicks or flosspicks handy: I use the pointy ends to gently press the whitestrips into the creavaces between my teeth: you definitely want to make sure to adequately whiten in between or you will end up with yellowish cracks and bright white surfaces. In the beginning, I also used the strips often and for longer periods of time than the box suggests. Probably bad for me, I don't care. Now I only need to use them once a month or less. My teeth went from being so embarassing that I had not smiled with my teeth showing since about 3rd grade, to my (now ex) husband saying they are so white they could glow in the dark. My teeth were beyond discolored, yellow and stripey, from both genetics and childhood medications. Now people compliment my smile and some have even asked where I "got them done." Nope, they're not veneers, just whitestrips. The Crest Whitestrips with Advanced Seal are probably the priciest whitestrips you will find, but if you are looking for the best results and an effective and easy to use strip, this is hands down the way to go.
Heard so many good reviews so I thought I would try them. Despite the steep price i thought they would pay off, but they haven't for me.
I been using these for a week and have seen no difference, except now that when i put on a strip after 5 minutes, my teeth hurt more than ever to a stage where I have to take them off. May try them again next week, but for now the sensitivity is to much to handle and is getting worse with every strip. Ver disappointed, was looking forward to having white teeth.
Very poor quality for such a high price. I bought a knock off of it for less than half the price and worked way better. Maybe halfway through my second treatment my one tooth started hurting really bad. And it has a very bad taste to it. Just very lousy
