Instructions for using Crest Whitestrips®.

- After looking through the product line, we've formulated this set of directions explaining how to use all types of Crest Whitestrips®.

This page outlines how to use Crest Whitestrips® products. We originally wrote these directions for Whitestrips Classic®, a product that has since been discontinued. We've since updated our pages so they include information pertaining to all of the different products that currently make up the Whitestrips® line.

This includes: Crest Whitestrips® 3D White - Vivid, Advanced Vivid, Gentle Routine, Stain Shield, Professional Effects, Intensive Professional Effects, 1 Hour Express, Luxe Supreme Flexfit and Luxe Glamorous White.

Directions for using Crest Whitestrips® -

  1. Which style of strip will you use?
  2. Getting ready.
  3. Placing the strips.
  4. Performing your treatment - How long, how often?
  5. Wrapping up your treatment session.
  6. Treatment frequency.

1) Crest® makes two styles of strips.

Whitestrips® come in two basic forms. The big difference between them is one type stays in place better than the other.

a) Sturdy, strongly adherent strips -

The boxes of strips having this design are labeled with the trademark Advanced Seal or FlexFit.

  • The strip itself is made out of a relatively thick, tough plastic.
  • The whitener/adhesive that's been applied is very sticky and is able to hold it tightly in place.
  • Products that have this design are: Crest Whitestrips® 3D White - Advanced Vivid, Professional Effects, Intensive Professional Effects, 1 Hour Express, Luxe Glamorous White and Luxe Supreme Flexfit.
  • The strips in this category are generally intended for longer wear times (30 minutes to 2 hours, depending on the product).

There is no question that these strips stay in place well. And if you've had difficulty wearing previous generations of Whitestrips®, this design will likely provide the solution that you need.

They are so adherent that Crest® suggests that you could whistle or drink water while wearing them (which, to us, seems a fairly accurate claim).

b) Flimsy, less adherent strips -
  • These strips are made out of a lighter weight, flimsier plastic. And the whitener/adhesive applied to them is much less adherent.
  • The consumer product reviews we've read typically contain the words: slippery, slides around, don't stick.
  • Products that have this design are: Crest Whitestrips® 3D White - Vivid, Gentle Routine and Stain Shield.
  • This type of strip construction is reminiscent of the older-style of Whitestrips®.

The Gentle Routine and Stain Shield strips are only worn for 5 minutes, so staying in place isn't much of an issue with them. The Vivid (not Advanced Vivid) is worn for 30 minutes, so keeping them in place may be an issue for some people.

Which style of strip should you use?

It only makes sense that most people probably prefer using the more adherent strips (Advanced Seal®, FlexFit®). And in fact, for just routine whitening (medium length treatments over the course of a week or more), only Whitestrips Vivid® (not to be confused with Advanced Vivid) has the flimsier, less adherent design.

That's not to say this product isn't as good as the others, it's just different. And for people who are more accustom to the old-style strip, this might be the one they prefer.

How to tell which kind you're buying.

We noticed that Crest® does a good job of displaying the Advanced Seal and FlexFit trademarks prominently on their products that have these designs.

It was also our impression that these products come in trapezoidal shaped boxes whereas the old-style strips come in rectangular ones.

Additional product selections are shown at the bottom of this page.

2) Getting things ready for your whitening strip treatment.

A) Cleaning your teeth.

In the directions for all of the products listed above, Crest® specifically states that they will stay in place better if you DO NOT brush your teeth before applying them.

As an additional aid, we've seen several consumer product reviews where the poster stated that they got better adhesion by removing excess saliva from their teeth first (by patting them dry with a towel).

B) Removing the strips from their packaging.

  • Whitestrips® come packaged in pairs (one upper and one lower) in individual pouches.
  • The two strips in each pouch are used for one treatment session and then discarded.

Simply tear open the pouch and remove the thin plastic carrier on which the whitening strips have been affixed. The strip for the upper teeth is the larger one of the two.

The side of the whitening strip that faces its plastic carrier is the side that contains the tooth whitener and is the side that needs to be placed against the surface of your teeth.

C) Don't peal a strip off until you're ready to apply it.

Even the sturdier forms of Whitestrips® are relatively flimsy items and generally tricky to handle. So before you peal one off its plastic carrier, make sure that you are all set and ready to go.

  • The newer generations of strips (Advanced Seal®, FlexFit®) are quite sticky.

    Be extra careful that you don't fold them over on themselves. If you do, you'll make a mess of things trying to straighten them back out.

  • With the flimsier, older-design products (Vivid, Gentle Routine, Stain Shield), it's less likely that you'll seriously damage any strips.

    But it is easy enough to crinkle them up. And straightening them back out will take a bit of work.

In general, as you peel the strip off it's carrier just be as careful as you can. You don't want to do anything that will make you have to touch or otherwise disturb the side of the strip that contains the whitener any more than you absolutely have to.

Also, use dry fingers. You don't want excess moisture to get on the whitener (and dilute it), or easily spread onto your fingers.

3) How to place your Whitestrips®.

Note: It's the gel (coated, sticky) side of the strip that's placed against your teeth. This is the side of the strip that was face down on the plastic carrier.

A) The strips need to be aligned properly.

When placing a Whitestrip®, you should align it with your gum line. Of course, its straight edge and your scolloped gum line won't match up exactly, so just do the best that you can.

Position the edge of the whitening strip (Whitestrips) with the gum line.

Place the strip so it fully covers your teeth.

Make sure to cover your teeth.

The idea is to maximize the amount of tooth surface that the strip covers over. Any portion of a tooth that lies beyond the edge of the whitening strip won't receive the same exposure to the whitener.

And yes, this type of positioning means that the strip will lie over small portions of your gums where they come up in between your teeth.


With the thinner, less adherent type of strip, even after you've placed one on your teeth you'll still be able to move it around somewhat to reposition it.

Advanced Seal® and FlexFit® products are much stickier. If you position one incorrectly, you can peal it back off. But you'll feel the strong tug, and wonder how much whitener you're leaving behind as you do. So it's nice if you can get things right the first time.

B) Once positioned, press the Whitestrip® into place.

Gently press the whitening strip (Whitestrips) in place.

Once positioned, gently press the strip in place.

Once you have the whitening strip positioned properly, gently press on it so to secure it in place and maximize its contact with each tooth's surface.

Fold the whitening strip (Whitestrips) onto the backside of the teeth.

Then, fold the remainder of the strip back behind the biting edge of your teeth.


Now that the first strip is in place, all you have to do is repeat the same process on your other arch (upper/lower teeth).

It doesn't really matter which arch you do first. But you'll probably find it easier to start with the lower, and do the upper second.

C) Wash your hands after handling Whitestrips®.

Always wash your hands after touching a whitening strip.

The bleaching agent that's applied to whitening strips is typically hydrogen peroxide. And it has the potential to react with any and all surfaces that it comes into contact with, not just your teeth.

Wash your hands in every case.

There is no question. You will get some of the strip's whitener on your fingers during the application process, so wash them once you're finished.

Signs and symptoms.

If you don't, you may notice that your fingers start to tingle, or maybe even burn. That's the peroxide reacting with your skin. It may even cause white patches to form. In any case, just wash your fingers off and you should be fine.

More serious or permanent complications might occur if you inadvertently touch your eyes, pets, furniture or clothing with your contaminated fingers. So be careful and always wash your hands after handling whitening strips or the pouch they came in.

3dwhite strips

i wiah I read this page first,before I purchested this product,I would have
Purchested a more sticker one.
My 3d white strips don't stick like I though

They don't work

Save your $$. Pulling them off the clear plastic strip and placing them is so difficult. And when/if you get it done, they DO NOT STICK. THey do not work. I wasted $72 when I bought from my dentist's office following a recent visit. Save your $$.


Hi there I just read your comment, so did you not continue to use the strips or was it just a one off problem you had?
I am using the Luxe Glamorous White and haven't came to any problems yet :-)


There seem to be a couple of issues being discussed here.

1) As far as staying in place, it would be our opinion that the "Advanced Seal" strips are very sticky and stay in place quite well (and infinitely better than previous generation Whitestrips).

2) "Pulling them off the clear plastic strip and placing them is so difficult" - We absolutely see how this might be a problem for some people. So the first time you do the process have all of your ducks lined up in a row so you have no interferences or distractions.

3) "They do not work" - This technology absolutely can work, and probably does for most people. But there can be a lot of variabillity in types of staining and between different people. There's no way in advance to know what type of results you will get.

Worked Perfectly

I don't see how anyone can have any problems!.. I use the Luxe Glamorous White and iv not had any problems so far :-)

They worked great for me.

The one problem I had was that they didn't stick well to my lower teeth. I think that was because they were more wet with saliva. So, I eventually started to pat down my lower teeth with a paper towel to dry them before I applied the strips. That seems to take care of the problem. My teeth are much whiter now then when I started.

great instructions!

I purchased a box of Whitestrips Classic months ago, and had never gotten around to using them. Evidently I'd opened the box at some point, though, because I'd lost the instructions! I bumbled my way through, but would have had far less difficulty had I thought to seek out instructions first! I'm sure this will help with tomorrow morning's application, and I can hardly wait to see my bright and shiny teeth in another week or so! Thank you for these excellent and clear instructions.


Thank you for leaving a comment. If you've never used Whitestrips before, on the first two days you might just use one strip each day, just to see how your teeth and gums respond to wearing them (in terms of sensitivtiy), then go from there.

Which side

I recently purchased the crest white strips professional effects. I opened my first strip and I was confused which side goes on my teeth. Is it the side i peeled off the plastic? Or the other side.? There also little patterns on one side of the strip. Need some clarity on which side of the strip goes against my teeth.


The side of strip that faces down on its plastic packaging is the side that is coated with the whitener and is placed against your teeth.

Supreme Flexfit - How often

The instructions say once a day for a strip, but nothing about the timing pattern. The Supreme Flexfit has 21 applications, are they used 21 straight days? Or is it once a week, or some other sequence. Since the instructions recommend only using no more than once a year, it is odd that no instructions on how often to use each treatment. Thanks for any help!


The webpage describing their 'Crest 3D White Supreme FlexFit Whitestrips' product says:
"Usage: Apply once a day for 1 hour. Full results in 21 days."

Especially for new users, it's commonplace to start with a reduced schedule (like every other day, or even more) just to make sure side effects (like tooth sensitivity) aren't going to be a problem for you.

Since teeth whitening is simply dependent upon the total dosage of whitener your teeth are exposed to, doing treatments every day vs. every other day will give the same end result, it just takes longer.

Thanks for your response! I

Thanks for your response! I read the usage part and made the assumption of 21 straight days, but with the advertised results lasting over a year, I questioned the 21 straight day approach. I also appreciate your comments on the reduced schedule, since I am a new user. Your last paragraph was most helpful in setting my expectations. Thanks for taking the time to advise and counsel, I found this extremely helpful!

Kinda confused

So I'm reading all the comments and it looks like these strips only whiten your teeth after a week or more of consisted used. I know it's not gonna whiten my teeth completely after one use but I think it's a little crappie that it takes so long to see any resultimate and that it only keeps them white for as long as you use them. Not to mention that they are painfully expensive. I cold NEVER afford to use thesearch things on a daily basis. Great idea but not a realistic possibility for a middle/lower class person such as myself.


Some of what you state is accurate.

This part is not: "and that it only keeps them white for as long as you use them"
The results you get with whitening strips will last as long as with any other whitening method, because all methods are based on the same chemistry (peroxide tooth whitening).

Also: "I think it's a little crappie that it takes so long to see any resultimate"
There just wouldn't be anyway a user's gum tissue could tolerate the concentration of peroxide that would be needed to produce single-treatment results using a whitening strip method.
If you want same-day results you should investigate in-office whitening (treatments performed by your dentist).
