Crest Whitening Stripes....
 

Ok just wondering, are those Crest Whitening Strips any count?? I was just gonna go get my teeth bleached but I figured I'd try to save some $$. Im just wondering how good they really are, if anyone has tried em let me know what they are like, Thanks :)

My sister and girlfriend used those and they seemed to work for them. I don't know how good they are for the enamel on your teeth though. Trial and Error my friend, trial and error.

that shit's scary. you're ingesting whatever crazy bleach-ass chemical shit they put on those to make your teeth white. to be fair though, i've never actually picked up a box and looked at it.

they work if you have good straight teeth, other wise try colgate overnight white.

They work, but not as well as getting your teeth bleached by your dentist.

Be carefull, I used some of the store bought whitening gel, and burned my tastebuds so bad that I couldn't taste anything for a whole week.

I've used them and so have my cousin, unfortunately my usage was far and inbetween. Her on the other hand kept it consistently and by the time a package was gone she looked like she robbed a drug store of peroxide.

I was talking to my dentist about these. He pretty much said that the quicker they work the more damage they do to your teeth. They will pretty much make your teeth extremely sensitive to the cold if you use the quick ones. He didn't condone the use but suggested using one that worked over a longer period of time or getting them professionally done at a dentist.

the crest white strips made my teeth sensitve while I used it, the sensitivity left about a week after I stopped and it has made my teeth noticable brighter

I use them and they work well. I did the two weeks exactly how they said, and then spot treat whenever I think I need it.

Does anyone know why whitening causes the teeth sensitivity side effect?

Those things are highly caustic. I wouldn't risk wrecking your teeth so they can be more movie-star white. I'd get it done by a dentist and fork out the $$$.

or, you could just dip your tooth brush in hydrogen peroxide, then dip it in arm & hammer baking soda and brush.
tastes bad, but it whitens the teeth, kills germs, and kills "odors".
old timers use a bit of salt for a scouring effect. but you have to be careful there...if you have thin enamel.

i used to brush like that every day..i had white, healthy, non-sensitive teeth...and I have no cavities.
i actually need to start doing that again..my teeth are a bit stained now.

Eee. In general, teeth whitening is about as useless as plastic surgery. No one is supposed to have the pearly white teeth you see on TV. But, since you seem intent on getting them whiter, talk to your dentist about it. He/she will explain everything to you in detail.

After I had braces for five years I got my teeth whitened. The dentist just gave me these rubber like retainers which you put this whitening gel in and wore these while you slept. It still made your teeth tingle and caused sesitivity to cold.
