I took before and after photos and could not tell any difference what-so-ever. They did not work for me. I am requesting the refund.

A friend recommended this product to me. I bought the product and it worked well. I've been getting many complements on my new smile. There is some tenderness to the gum area and some tooth sensitivity but it goes away. I was afraid to use this product because i have sensitive teeth and i was worried it would be painful as other reviews stated. I recommend it.

Be careful with tooth whitening strips. The products used give the appearance of whiter teeth as they erode fine layers of enamel from your teeth. It is far safer to go for a fast and quick in-office laser treatment where in one hour you would get better results from any amount of use from the strips. Laser teeth whitening in-office treatments can be found from companies such as www.ultimateteethwhitening.co.uk

can see improvment but are EXTREMELY annoying to use. They fold up, move around, and definitely do not stay in place on my teeth.

I had never used whitening strips before and decided to give them a try when someone took a photo of me standing next to someone else and I noticed their teeth were considerably brighter than mine.

I landed on the Whitestrips Pro Effects mainly because they were the strongest available at the local Target. The kit included 20 packets that you could use twice daily for 10 days.

After the first couple of applications I had figured out it's easiest to get your teeth dry and apply the strips...top teeth first and then the bottom. Once you get them on I learned to hold them in place with your lips pressed against your teeth. It was easiest to sit down and just watch TV, read, surf, whatever.

I always did 2 packets a day. Most of the time I did them back-to-back at night. I'd wear the first set for 30-35 minutes and then remove. Wipe the gross paste off my teeth/gums and then spit a few times. Then apply the next set for another 30-35 minutes.

I saw several people post about their teeth being sensitive. I will say that after my first couple of days my teeth did get sensitive. Mostly when having something hot/cold against them (soup, ice water). Not painful but annoying. It did seem that my teeth got progressively more sensitive on days 3, 4, and 5. It never was bad though. I will say that I took about 4 days off from wearing them at the halfway point because I was out of town traveling and forgot to bring them with. I'm sure that helped giving my teeth a break for 4 days. I just finished the last set last night and after the second 5 days of wearing them my teeth are again slightly sensitive. I suspect by tomorrow they'll be back to normal. So taking a break for a few days at the midway point might have helped with the sensitivity. I never once used sensodyne or anything similar.

I couldn't be more happy with the results! My girlfriend noticed after about 3 days and she was really happy with the results as well. I decided to take pics at the start, midway point, and the end so I could compare side-by-side and see the progress. I'm from the Show-Me state and it's easier for you all to see than to believe. So look and see for yourself, I've assembled and attached a pic. It made a huge difference. They still aren't pearly white but they are several shades brighter and I couldn't be more pleased!

I have tried the pro strips once and have sensitivity on my teeth from it after once use. My teeth were for the most part already white as I used 5 min plus white for 7 years since my braces were off and had no sensitivity to that. I have 6 more days to go on the pro strips but not sure if we will put our teeth throught the pain of them again. The pain didnt start until the next day which continues. As far as whitening, I am sure it works great. i may just go back to the 5 min plus white that I know works for me without the pain. I think the pro strips are just too strong. i would recommend a dentist referral with these pro strips. Good Luck!

After following the instructions on the box and finding that thay could cause some teeth sensitivity I decided to give them a go.....the first day I was cautious and only used them for 30mins. The second day the same, third day I decided to use them twice aday for 30 min as recommended and I had severe tooth sensitivity for 8 hours that strong paracetamol didn't ease. I read that sensodyne toothpaste helped so I have used it for 2 weeks and then thought i'd try the strips again starting with 20mins......however here I am again in severe pain. It did make a slight difference but the pain is too severe to continue use. I feel Crest should have more of a warning on their products and I wish I had consulted my dentist before use.

It's been about 5 days since i started using this and i have noticed an amazing improvement. I didn't have yellow teeth before just a little dull. I am now seeing them so white when i smile. It's a pretty awsome feeling. I recommend this for anyone who doesn't have an extreme yellow mouth.

They don't work...

I noticed a difference after 2 days my teeth were whiter!! For me the strips are pretty easy to apply it was tricky at first but you get used to is. My teeth were sensitive after the first day and were hurting pretty badly but I bought some sensodyne toothpaste and it worked GREAT!!!! I can continue to wear the strips with no sesitivity!!!

I used pro strips for 3 days now and i love this product my teeth are REALLY white now and it doesnt bother me at all i can get ready and dressed and everything , i love them alot . My gums dont bother me and the bottom sticks on REALLY GOOD!, my teeth are really white , and i only do this once a day for 30 minites .. my teeth are probley 4 shades lighter allready

I love crest whitestrips! my teeth are beautiful and white now and people always compliment me on my smile. i might sound like an addict...well i guess i am. haha but seriously, i don't know what i'd do without them!

I love these. The first time I used them, there was some pain and discomfort after about the 5th day. (My teeth can be sensitive though) but I kept buying them, and the pain decreased everytime. Now I don't have any discomfort what-so-ever.

They really worked well on my teeth, and I usually leave them on for about 10 extra minutes. I have the brightest smile of all my friends.

This was the first teeth bleaching product I ever used and I'm glad to say that I was happy with the results! My teeth are naturally pretty white and now people say that they glow. Pro effects worked well on my teeth.

Just remember to lay down while bleaching and, according to my experiences, use it only once a day! Otherwise your teeth will get sensitive.

A good product, I recommend.
Going to try "Crest Whitestrips Premium" next. :-)

This are a complete waste of money. I called Crest and requested a complete refund and told them I had lost 3 of them just trying to get them off plastic and onto my teeth. The move all over the teeth and are hard to remove from packaging and hard to apply correctly. I would choose any other product over this one to get your teeth white.

I have been using these for two days and I see a bit of a difference, maybe 1-2 shades whiter. Unfortunately after my 3rd use, my teeth ached for 9 hours. The pain was so bad I couldn't even talk. I might try once more, or look around for other products. The whitening aspect is very good, but it's not worth it to go through all the pain.

I've been using these strips for 4 days and I am not that impressed. I guess I'll have to wait it out and see if there is a big change. So far there has been a tiny bit of change but hardly noticable. The bottem strip slips all over the place and they cause you to drool a lot. Yesterday I started feeling that tooth sensitivity that others have been talking about. I don't know how I feel about this yet.

This is my first time trying the advance seal, but second experience with whitestrips---my high school reunion was in June, so I started the pro-effects 10 days beforehand...They made my teeth so damn white, I could not believe it...it was crazy! However, they did not last very long, they are still a little white, but it went away pretty much, and its only been 8 weeks...I just bought the advance seal yesterday and have just applied them. They stick ten times better, I was pretty impressed with the difference...it's almost like putting scotch tape on....really stuck well. However, I am a little skeptical that they will work as well as the pro-effects because there is not near the same amount of solution on the strips as there was with the pro-effects...i can deal with the slipping, and would rather have more solution going into my teeth, than worrying about them slipping. so, next round, i will buy the pro-effects, which are fine. The only down side is that you have to basically be quiet and cant eat or drink anything for 1/2 hour---which isnt that big of a deal.
Love the pro-effects, they worked AMAZING and came recommended by a girlfriend of mine who is a dental hygenist---she told me that her dentists compares the results of pro-effects with zoom whitening, which is really amazing for 40 bucks....she also told me that zoom whitening was extremly painful, and sends things called 'zingers' through your teeth that lasts up to a week! NO THANK YOU!
SO, good luck everyone, and I highly recommend the pro-effects!

only on second day but they have made a noticable difference already, i have had absolutly no pain not even any slight sensitivity. i havent had any problems keeping them on my teeth, my advice would be to dry your teeth before you put them on then they will stick very well. they dont taste brilliant but its not that noticable. what i do while i am wearing mine is to put a 30 min alarm on my phone and play a video game which distracts you from the slight bad taste and it passes the time in a fun way. i would strongly reccomend these to you if you are looking for a good way to whiten your teeth.

I have tried pretty much all whitening products. Honestly you get what you pay for. If you spend $30 bucks at wal mart on the crest strips you should not be complaining about how they slip or are uncomfortable. If you simply don’t drink coke, tea or any dark sodas and don’t smoke, dip, etc... You’re not staining your teeth as bad. It’s like weight lost...why work out then eat a candy bar then complain that you’re fat. Once you have decided to whiten your teeth you should change your habits as well so that you can see results and last. Also floss and take care of your gums then you wouldn't see white spots or have burning of the gums... It’s a peroxide solution so there for its going to go to any spots that are inflamed, just like if you would pour peroxide on a cut. Crest strips do work and brighten your smile but remember they are Over the Counter, so don’t be expecting results like dental bleaching.

I only got one front tooth left and it was all yellow from eating corn and opening tins with it , but now since i started using them there whitening strips , ol' choppers nice and white and billie joe wants to marry me

I saw significant results! My teeth are pearly white and I can't stop smiling so others can see. I didn't have any drooling or sensitivity problems but when I taken the strips off I manage to swallow some of the gel. Which was a bitter taste and made me ill for the first three days. The strip on the bottom moved around a lot but after five days I got used to them sitting on my teeth.

didnt whiten at all and destroyed my enamel.

I just recently bought a crest pro effects kit two days ago and although they are kind of pricy I thought I'd give them a try, using them twice a day and as directed I am actually amazed at how well and fast they're working!!:) I have felt the pain/sensitivity in my teeth but only for a minute and it's not that bad but I do feel like you have to keep readjusting them every now and then but if u put them on correctly lining them with ur top gumline and bottom then they seem to fit a little better.... But all in all I'm very pleased and alot more confident;)

I didn't have all that yellow of teeth, but i was still didn't feel like they were good looking and im going to meet my bf's parents tomorrow night.. i started these 5 days ago.. and my teeth look awsome
