There are many different kinds of teeth whitening kits on the market and one of which is the Crest white strips. With these strips, you would mold a strip to your teeth one on the top and one on the bottom row of teeth. They are coated with whitening gel containing either hydrogen peroxide or carbamide peroxide. You will leave these against your teeth for five minutes every day in order to get the full effect. See results in about 10 days after starting your treatment.

Do Crest White Strips work After one Use?

Yes, they do start working after only one use as soon as you put the strips on your teeth the hydrogen peroxide seeps into the enamel and starts the whitening process. You will take a strip of Crest White Strips and put one each on the top and bottom for of teeth. Make sure they mold to your teeth and sit firmly against them. Then leave the strips there for a period of five minutes.

This will give the carbamide peroxide or hydrogen peroxide gel time to seep into your teeth. Both of these types of peroxide are highly effective whiteners. You need to allow them time to work, and you need to ensure that you use the strips as directed daily in order to start seeing the results you want. A brilliant, radiant smile.

However using the Crest 3D White Whitestrips Vivid, you will only begin to see the results of the whitening from around 10 days. If you need something to show results quicker than that, you will need to use the Crest 3D White Whitestrips Advanced Vivid or Professional Effects in order for you to see results in 3 days.

So although like we said to start with, the formula starts working immediately, results, however, may take a little while to be seen. Don’t give up and stop using the strips regularly because you do not see results instantly, or try to use more gel, or use it more often, patience is the key to that brilliant smile and you will not regret choosing Crest White Whitestrips in the long run.

Do Crest White Strips work on Yellow Teeth?

Yes, they do work on yellowed teeth. Each of the flexible strips is coated with a gel containing either carbamide peroxide or hydrogen peroxide. Each strip is molded to your teeth, using one to coat the top teeth and one to coat the bottom row. The gel seeps into the teeth as you hold it against them. Hold against them for a period of 5 minutes.

You will have to do this on a daily basis and results will only be visible in around 10 days if you are using the Crest 3D White Whitestrips Vivid or three days if you chose to use the Crest 3D White Whitestrips Advanced Vivid or Professional Effects.
However, it should be noted that some people teeth are naturally yellow and although the strips may lighten the color it will not completely make them white.

If they are stained yellow from nicotine or caffeine you can clean them and get them white again using the Crest White Strips however if your teeth have always been yellow they will remain so, that is not to say they are unhealthy though. Causes for a yellow tinge to your teeth, where they will never be fully white again are many.

Some of the reasons for yellowed teeth that will never be fully white are that this is their natural color, you were on medications while your teeth were forming. You had too much fluoride during the time your teeth were forming called fluorosis, there has been enamel abrasion on your teeth, in other words, you brushed too hard or over brushed your teeth when younger.

These are some of the reasons for naturally yellow teeth.
Although the Crest White Strips will reduce the stains on your teeth, they will not be able to change the coloring fully, only cosmetic surgery will do this.

Do Whitening Strips Damage Teeth

No, they do not damage your teeth. They are safe to use and are highly effective. You must, however, use them in the way directed. Use them for a period of only five minutes per day. They are the same ingredients used by dentists to whiten your teeth, namely hydrogen peroxide and carbamide peroxide. Hydrogen peroxide in quantities of 3% are proven safe for use in orally and the Crest White Strips do not exceed this limit at any time.

During extensive testing, it has been clinically proven that Crest White Whitener Strips are formulated to be extremely safe. They will not damage your tooth enamel in any way, as long as you use them as directed and do not leave them on your teeth for extended periods of time. However, they will not work on any veneers, bridges or false teeth.


Using Crest White Strips is a less messy and less time consuming, not to mention more economical way to lighten and whiten your teeth. They work as they are coated with the whitening gel and you simply mold them to your teeth for a period of five minutes a day and see results in only 10 days.
