Crest Whitestrips

Does anybody use Crest Whitestrips? Any feedback on them?

They seem really tempting to me. Any information on these Crest Whitestrips would be greatly appreciated!
 
You do know that all whitening strips and procedures are nothing but bleach treatments, don't you ?

This not only whitens your teeth, it also destroys the enamel.
 
Just rinse with Peroxide daily. It'll take longer but your teeth will get whiter.

My teeth got really sensative while using though and it sucked big time.

That's because the outermost coating on your teeth, also known as enamel, was breaking down. Basically, your nerves were becoming more exposed to the air and whatever was in your mouth at the time.
 
I call B.S.
Whitestrips contain peroxide, not hypochlorite (bleach).
Furthermore, a family friend who is a dental surgeon recommended them. (On my inquiry, not because I have hideous teeth, TYVM).
They do work, but they only fit over the front teeth (that are visible when you smile), so you still have yellow teeth in the back. If that bothers you, you could use one of the mouthguard systems (rembrandt?) or go have a dentist do it ($$$).
 
I tried them. Really expensive. And I got really sensitive, I mean I couldn't stand it my teeth were throbbing, i had to discontinue. Now i have a mostly unused box laying around 🙁

explain sensitive? like did they start hurting your teeth.
 
I'm using them right now... halfway through the box and they're great. There's a noticeable difference already. Well worth the $$ if your teeth aren't oversensitive.
 
Oh, I'll add, my teeth didn't get painfully sensitive, but oddly enough my hearing did. A lot of sounds were like nails on a chalkboard all of a sudden. Took me a while to figure out it was the whitestrips. Weird.
 
i thought they worked very well, but i hate the fact that the gel would ooz everywhere. i felt like i didnt want to swallow the whitening gel so i would keep drooling. i like the whiten pen/wants even the mouth guard things better.

Didn't physically hurt them. But they sure did make it feel like it was hurting them. I tried to ignore it at first, but it just got worse. It felt like a bad headache, but in my front teeth.
 
You get sensitivity in places where your enamel is thinner (like early in cavity formation.) I didn't like the whitestrips because they slid around on my teeth. I prefer to use trays, whether custom or not (done both).
 
i used them, not the one week premium ones but just the regular ones, i recieved 2 comments from people about how white my teeth were. So I know they work.
 
I used them a couple times it always seems to hurt more than I thought it was worth doing though. So I don't use them anymore. Its not a big deal for me though my GF has them laying around so I tried and didn't like thme eh.

hydrogen peroxide

hydrogen peroxide, chemical compound, H2O2, a colorless, syrupy liquid that is a strong oxidizing agent and, in water solution, a weak acid. It is miscible with cold water and is soluble in alcohol and ether. Although pure hydrogen peroxide is fairly stable, it decomposes into water and oxygen when heated above about 80°C; it also decomposes in the presence of numerous catalysts, e.g., most metals, acids, or oxidizable organic materials. A small amount of stabilizer, usually acetanilide, is often added to it. Hydrogen peroxide has many uses. It is available for household use as a 3% (by weight) water solution; it is used as a mild bleaching agent and medicinally as an antiseptic. The 3% solution is sometimes called ten volume strength, since one volume of it releases ten volumes of oxygen when it decomposes. Hydrogen peroxide is available for commercial use in several concentrations. Highly concentrated solutions were first used in World War II by the military, e.g., in fuels for rockets and torpedoes. It is used as a bleaching agent for textiles, e.g., wool and silk, and in paper manufacture. It is also used in chemical manufacture. Hydrogen peroxide is prepared commercially by oxidation of alkylhydroanthraquinones and by electrolysis of ammonium bisulfate. It can also be prepared by reaction of barium peroxide with sulfuric acid and is prepared (with acetone) by oxidation of isopropanol. Hydrogen peroxide was discovered (1818) by L. J. Thenard.
