5 Top Whitening Strips Review

#1. Crest 3D White Strips Professional Effects with BONUS 1hr Express

The Crest 3D Whit Professional Effects strips are widely regarded as the top of the range choice. These strips will give you the benefit of the professional grade whitening without the huge costs involved with the visit to dental office.

Best choice here is to purchase the package with 2 one hour Express treatments. These will give you a 2 times use when you want to have a quick stunning results.

With the first one hour Express treatment you should see an immediate improvement which lightens the teeth a couple of shades brighter. This could be used when in a real pinch, like for example going to a party, wedding, photo shoot or some other important occasion which could end up with your smiling photo tagged on a friends Facebook page. It is important to mention that you should NOT use these Express strips daily. That is why it is called the 1hr Express.

It is not that easy to find the 1hr option in regular stores. Most often you will find it much quicker and cheaper online.

Let us now discuss about the differences in these three Crest products: 3D White Professional Effects, the Glamorous White and the Noticeably White. The main selling point for the 3D White Professional Effects is the long lasting effect which can last the whole year. Since we have used it for some time, we can say that 3D Professional Effects really gives much better results compared to Noticeably White or even Glamorous White. In this case, it would be safe to say that the increased cost of the product also gives better results. Various reviews and consumer reports also confirm this observation.

Also, the manufacturer claims that the product is able to remove incredibly 14 years of stains. Now that is a really long time to neglect your appearance and, if true, would position this product as a sure-fire solution for almost anybody.

To use it properly, you should keep these strips on your pearly whites for 30 minutes per day. The gel used in the strips will hold them firmly in place for the duration of use and there is no leakage at all. The whole process lasts 20 days and is longer compared to Glamorous White and Noticeably White. Excellent reviews that 3D White had received across the board are very much in line with our own experience. Considering what it offers, the price is not too high.

  1. Crest 3D White Professional Effects Whitestrips Teeth Whitening Strips Kit – 20 Treatments

If you are looking a fast and reliable whitening strips, pay attention to the product in question. Almost all people who used it, claim that it is one of the quickest, when it comes to the results, on the market. First of all, you should use a strip for 30 minutes per day, which is less than most other products require.

Then we have an impressive Advanced Seal Technology which will keep the strips safe and sound even when you talk or drink. The grip is implemented in such way that they cannot be accidentally removed, but once you need to remove them, it is extremely easy.

The first, major improvements can be seen after 3 days, but for the full effect, you will have to wait up to 20 days. In any case, they are quicker than most similar products, while maintaining the safety and simplicity. It is a common thing to forget about them while having the strips on your teeth. The grip is amazing, but they are well-designed, meaning that you won’t actually feel them. According to consumer reports, permanent users forget that they even have the strips.

It is impeccable to use the strips once per day for no longer than 30 minutes. They won’t damage the teeth layers nor have any effect on the gums, but keeping them for a longer period of time may cause increased teeth sensitivity. The effect will last for at least 12 months, thanks to the sophisticated formula these strips use.


  • Should be kept on the teeth for only 30 minutes per day
  • Large package
  • Advanced Seal Technology
  • Long-lasting effects
  • Tested and safe to use


  • May cause minor teeth sensitivity
  • Less powerful than similar strips

  1. Crest 3D White Whitestrips with Light – Teeth Whitening Strips Kit

The effect you will get with these strips will last for 36 months, which is simply impressive. They have the same enamel-safe ingredients which are used in dental offices and which are proved for being safe and effective at the same time.

A thing or two about the strips you should know is that they are lightweight. Obviously, all of them are, but these ones are thinner, meaning that they feel more comfortable when placed on the teeth. Let’s just add that the grip and the strength of a strip aren’t compromised.

When used in bright light conditions, the effects are even faster to achieve and they are even more impressive. The process targets the yellow stains deep in the first layer of each tooth. They are first weakened and later removed completely. In other words, there won’t be any pieces of evidence your teeth were yellow in the first place. The only down side about this product is the time you need to spend using it.

You need 60 minutes for each whitening treatment and additional 10 minutes to use the light with the strips still on teeth.

The end effect is quite dramatic. If you use them on a permanent basis and obviously brush your teeth daily, the effects will be almost the same as if you visited a dentist and had expensive teeth whitening.


  • Effects will be visible after 36 months
  • Lightweight and water resistant strips
  • Light boosts the process
  • High efficiency in people who drink plenty of coffee


  • The price
  • 60+10 minutes per day per treatment

  1. Teeth Whitening Strips Teeth Bleaching System – Professional At Home Teeth Whitening Strips

These strips are actually quite different than the previous three products. As you can see first, the manufacturer is different, but the real difference is in the ingredients and the strips themselves.

The first thing you are going to notice is the result after just one treatment. Yes, it is actually possible to get whiter teeth, without stains and yellow deposits after just one treatment using these strips. Of course, the more you use them, the better results you will get. In the package there are 28 strips, meaning that you will have plenty of them available to reach the maximum effect.

Using the strips is easier than you may imagine. There are 3 steps and each one takes a few seconds to complete, except the second one which means that a stripe should be left on the teeth for 30-60 minutes. After this process is done, you will have to remove the strip and all is done. The process must be repeated once per day.

Additionally, we would like to mention that the formula is one of the safest you can get. Actually, dentists use it for patients with extremely sensitive teeth. As such, you won’t feel any issues even if you are one of the aforementioned patients.

The stains, old up to 10 years, will be completely removed. While wearing a strip, you will be able to talk, drink water and laugh. They are transparent, so people around you won’t actually see them. The efficiency, according to a research is 25 times higher than with teeth whitening toothpaste!


  • Ideal for sensitive teeth
  • Very affordable
  • You can drink water and talk while using a strip
  • The first result is visible after just one treatment


  • Stains older than 10 years won’t be significantly affected
  • Slow in a case the stains are too hard to be removed

  1. ProDent Teeth Whitening Strips – Professional At Home Teeth Whitening Strips

After the first treatment you will see the results, but only after the complete process, you will be satisfied with these strips. They are made to be extremely reliable, safe to use and affordable. In a matter of fact, they are the most affordable teeth whitening strips we were able to find in this category. In addition, each package has a total of 28 strips, for 14 treatments in general.

Using them is the same as other teeth whitening strips and the time needed to a stripe to stay on the teeth is around 30 minutes. When it comes to sensitivity, these ones are probably one in the top end. Regardless of how sensitive your teeth may be, the strips will make sure there are no drawbacks. The same fact applies to the gums. Stains up to 10 years will be removed without any traces.

Combine efficiency made this product the most common choice by elderly people. Most of them claim that they are 100% satisfied.

This formula is also light-activated, meaning that the strips can be exposed to the light, which is a benefit if you need to talk while wearing strips. They feature non-slip design capable of staying on the teeth regardless of what a person does at the moment. In the package, owners will get the detailed instructions, which are highly beneficial if you are a beginner.


  • Light-activated formula
  • 14 treatments by a single package
  • Detailed instructions
  • Non-slip design
  • Sensitive


  • Complicated to adjust

At the end, we must say that most people claimed the Crest 3D White Luxe Whitestrips are the best. We tested them and we agree! They will remove stains up to 14 years old and there are enough strips for 20 treatments plus two Express treatments if you need your pearly whites to became shiny white fast. Using them is simple, effective and safe, everything teeth whitening strips must provide. If you are in the mood for trying some other product, others on the list are recommended as well.

How Yellow Teeth Damage Our Social Life and Confidence

Yellow teeth discoloration can be really depressing and certainly unattractive and doesn’t send a good message to anyone who looks at you.

Every time you look at the mirror and see yellow teeth like these on a photo your confidence lowers and you just start loosing that natural inclination to smile at people when you feel happy otherwise.

Some people try to cover their mouth with a hand to escape the embarrassment or even start lowering the eyes in disgrace.

You don’t need to read social studies regarding the psychological effects of bad oral health. It is enough to remember your own first impression (and the second, while we are at it) of a person you see having a bad teeth, yellow in color and some obvious signs of tooth decay. Yes, it is that important to presentable regarding the condition of your teeth. And that doesn’t mean you must have one of those sparkling Hollywood smiles. Just a well taken care of set of pearly whites in their natural bright white color is great enough.

It is a common sense, and the studies have confirmed it, that both men and women immediately look for the teeth when judging their potential date. That speaks volumes on the importance of oral health in daily life!

Many things about your life could be potentially gleamed when looking in your mouth. It may reveal your general condition of health, your smoking habits, whether you consume a lot of dark colored beverages and what kinds of food you eat.

Some of The Most Common Causes of The Yellow and Stained Teeth

As we had just mentioned your overall dental health is very dependent on your self discipline in the kinds of foods and drinks you consume the most. Many popular food products are usually to be blamed such as:

  • You will not like this but if you want to have your teeth as white as possible that also means no Coffee and Tea! If these are the drinks you consume often, they will transfer their dark pigmentation to your enamel and make your teeth yellow. At least put some milk or cream in it to neutralize these pigments as much as possible.
  • Do you like Carbonated Drinks? We know you hear it a million times how these are bad for your health. Guess what, they will also stain your teeth. You enamel will also erode by the influence of high acidic content and the presence of so called chromogen. Some of the most popular colas, dark in color, will enhance discoloration with each use. But, not only the dark drinks are the culprits, some of the light colored drinks have enough acid in them to stain the teeth.
  • Some Sauces which also contain a lot of acid, if consumed often, can damage your teeth. One prime example is soy sauce which can really contribute to the overall staining of your teeth. The darker pigment of soy sauce can really decrease your chances of maintaining that bright smile.
  • Red vine which is a favorite beverage that goes along with dinner for many people can really have a negative impact on your smile. And the problem doesn’t simply arise from the darker pigment but also from the acidic value that it has. Compared to other types of vines, red vine also causes more damage to the enamel. One thing you can do to alleviate the problem is to also drink water along with the vine to try to minimize the damaging effect.

Tooth discoloration can be caused by many more foods besides the ones already mentioned. They include chocolate, sports drinks, berries, various kinds of sweets and so on. The point here is to be aware of the possible issues and take preventive measures or replace them with other foods and drinks more gentle on your pearly whites.

Here are some of the other causes of stained teeth which, depending on the person, can even be the most prevalent cause of teeth staining.

  • Age: As we get older the enamel becomes thinner which in turn makes the yellow color of dentin more visible.
  • Genetics: Some genetic disorders can case teeth color to have even gray or purple teeth. To name the few, Amelogenesis Imperfecta and Dentinogenesis Imperfecta are some of those conditions.
  • Intristic Stains: These kind of stains occur within the internal structure of the tooth. Some people, who had excessive fluoride intake as children may develop those. Other causes may be by use of certain medications containing chlorhexidine and sometimes even by the bleeding of the permanent tooth.
  • Smoking: You had probably seen some people, who are heavy smokers, develop really stained teeth. All that tar and nicotine which is in tobacco finds it’s way into microscopic openings in the enamel and also makes layers of smudges on the surface of the tooth.

The Advantages of Using Teeth Whitening Strips

After reviewing products above we now want to focus on going a little bit deeper on different benefits of using whitening strips for teeth whitening.

Some of the biggest advantages are:

#1. Professional Results

In many cases when using whitening strips you can get the same effect as if actually going to a dentist for a teeth whitening. The end result is what is important here and if the smile is improved without visiting the dental office, even better.

For each degree of teeth staining there are products available that are geared to solving those problems. You can do self evaluation by reading our Teeth Stains and Discolorations article. If you are a heavy smoker we also did a separate review for whitening strips appropriate for smokers.

#2. Easy to Use

Teeth whitening strips are easy to use even if you had never used them before. In the package you will find strips that will fit your upper row teeth and accompanying pair which will fit the bottom row of teeth.

You should start by removing the strip from the translucent plastic it is attached to and align the top part of the strip with your gum line. You can use the bathroom mirror to help you with this. After that all you have to do is to firmly press whitening strips to your teeth. After you had put both strips on, you can try to suck the air between your teeth to try to increase the contact surface between whitening strips and teeth even further.

You don’t have to go crazy with it, just make sure you had put them on as tightly as possible.

After that there is nothing more to do but to wait for the recommended amount of time for the whitening strips to do their job.  If you followed the proper procedure for putting on the whitening strips and have purchased one of the quality recommended one, they should not fall off or otherwise move around until it is time to remove them. This in turn ensures the best possible efficiency for teeth whitening.

When the recommended time has passed you should peel off the strips and put them in a trashcan.

Best Whitening Strips Are Very Affordable Compared To In Office Treatments

If you compare teeth whitening kits to a procedures done at the dental office you will see that the whitening strips are much cheaper option.

But comparing the actual results of the procedure is the truly important benchmark that should be taken into consideration. Getting the best value for your money that you had put into something is almost always the best choice. The professional grade results that good quality whitening strips provide can really drive that point home.

When you go to a dentist for teeth whitening a session can cost between $300-$600. To get the best result often a few sessions are necessary.

Professional teeth whitening done at the dental office is known to have a greater lasting time compared to whitening kits. However, the price should also be taken into consideration. And when everything has been put to paper whitening kits start to emerge as a clear favorite. We mean, who wants to pay 1000$ more for teeth whitening. We are sure you could put that money to good use somewhere else.

Results That Last Moderately Long

On average, if you decide on teeth whitening strips you will have to whiten teeth once or two times a year.

Since, there simply doesn’t exist a permanent whitening procedure, every 6 months it will be necessary to do the treatment again in order to preserve the bright smile attained the first time.

So, when you apply the full treatment as prescribed on the instructions, it would be reasonably to expect the effect to last a couple of moths at least. Be sure to also avoid some darkening foods and drinks as we had mentioned above.

How do price paid and the duration of the effect stack and is it worth to pay extra and do the treatment in the dental office?

Here is the quick calculation:

Whitening Strips

$50 x 2-3 treatments per year =$100-150 per year

Professional Dentist Treatment

1 treatment x 3 sessions of $300-500 for full effect = $900-1,500 per year

What can bee seen from this calculation is that the choice is weather to whiten teeth 2-3 times a year by using whitening strips which would result in the savings of about $800-1,350. Or the other option would be to go only once a year (for 3 sessions) done professionally and spend that extra amount unnecessarily.

Possible Risks Or Downsides To Using Whitening Strips

As nothing in the world is perfect and there are always pros and cons for every product, we will now go into some risks that are associated with using the whitening strips. You should also know that these risks are the same if you decide to do in office whitening.

#1. Possibility of Uneven Whitening

Teeth shape is basically complex 3D surface which is irregular and unique to each person. Since whitening strips are made as a 2D surface there can always be some small areas which were not completely covered during the application of the strips.

This is why it is important to follow the proper use procedure that we have described above and to make sure that whitening strips are place as tight as possible to your teeth.

Since you will be doing about 10 or more sessions, depending on the product you purchased, chances are that the same small areas will be the problem with each session. That means that, in reality, you will have some small shade variations and if you were not careful with the application instructions, you may be even left with some yellow edges sticking out.

#2. Possible Gum Irritation

Luckily the bleaching agent which is used in the teeth whitening strips is not as powerful as the one dentists use. But, in some people it is possible that it can cause irritation of the gums after use. This might be more likely if you purchased one of the lower quality products which are not preventing gel from coming out from under the strips.

If you find out that the whitening strips are too large for your teeth and would cover the gums with a big overlap, you can easily use the scissors to cut down the strips a little bit to better match your gum line.

#3. Possible Tooth Sensitivity and Damage

When using whitening strips withing the guidelines specified by the manufacturer you should be safe from tooth sensitivity. You should not try to apply several teeth whitening treatments back to back in order to force that glittering smile to show up quicker. Instead, let some time pass and enjoy your pain free brighter smile for a while before you continue your journey to perfecting it.

Excessive application of the active whitening agent can erode the enamel which can cause pain and increase the risk of tooth decay. That is why you should not try to keep the whitening strips longer on that is specified in the instructions.

Before even starting the treatment, you should first fix all cavities, gum disease or other problems you may have in the mouth. Also, best results are achieved if you go to your regular cleaning appointment with dental hygienist just before you start the whitening treatment. Treat teeth whitening as a finishing touch you have to do in order get that smile to perfection.

After you have understood the possible risks involved and noted the things you need to take care of, you now have all the necessary understanding to make the best possible purchasing decision and enjoy your best teeth whitening strips.
