Do Whitening Strips Work and If So, How?

Dental health is not just about having a nice set of teeth to show to the world, but it’s also about basic hygiene and staving off diseases. Yellowing teeth, stubborn stains, and other problems in our oral cavity can diminish our appearance, self-esteem, and overall health. Unfortunately, unhealthy eating habits and the use of tobacco has rendered many people’s teeth an unsightly shade of yellow or gray.

For those who are concerned about this phenomenon and want to look into whitening their teeth, there are several options available open today. There are professional whitening procedures, but many would first prefer to or for a simpler and easier route. Whitening strips are one such offering, but there might be doubts of their working. Let’s have a more detailed discussion of this item and gauge whether it can be useful for us or not:

About Whitening Strips


The term ‘whitening strips’ is pretty self-explanatory. In a nutshell, these are strips that might help us whiten our teeth, doing away with stains and/or discoloration that has accumulated over the years.

You can probably buy whitening strips at many drugstores and pharmacies, not to mention online platforms. There are several brands out there, but they’re not all of the same price or quality. Over-the-counter whitening strips are usually deemed safe by the health authorities, but they could harm our teeth if used improperly.

Materials of Whitening Strips


Teeth whitening strips are mostly made from synthetic plastic called polyethylene. This is the plastic that’s used for making packaging, food containers, plastic bags, etc. For teeth whitening purposes, the material is cut into strips, which are small and flexible. These strips are then coated with a type of gel that contains carbamide peroxide and hydrogen peroxide. These peroxides act as the whitening agents. The gel penetrates the enamel layer of our teeth and provides a bleaching effect. The result is usually a whiter and brighter appearance for your teeth.

Other substances on the strips include adhesive polymer, water, carbomer, and glycerin. They may also have a thickening agent and sodium saccharine to provide some taste.

As you can see, there are several chemicals that go into the making of OTC teeth whitening strips. These might be safe if you stick with small doses. Then again, the small disease may not be so effective.

The Working of Whitening Strips


According to the advanced teeth whitening strips dental 360 reviews and other product reviews, teeth whitening strips do work to some extent. Their process works through the chemical mixture that coats the strips. The user places one strip on the bottom row of teeth and one on the top. This will make the chemicals lighten the teeth over a period of time. The exact length of this period depends on the brand you’re using as well as the extent of damage to your tee.

Most OTC teeth whitening kits have several strips inside. Some might have as many as 84 pieces, while others contain just enough a few day’s use. When you’re buying a kit to try out, keep in mind that it’s best to use these strips twice daily.

In your search for teeth whitening strips, beware of any product that claims to whiten teeth right away or within a day. They will probably not work; if they do, the chemicals on them are usually too strong and will further harm your teeth. Do your research first and look up the best teeth whitening strips reviews before deciding on the final product.

How Whitening Strips Impact Our Teeth


Products like the Dental 360 White Strips for Home Use are very convenient, but we have to be careful about using them. It’s best to follow the instructions on the box every time and only use these strips sparingly. If we misuse or overuse the strips, both our teeth and gums will suffer.

Before using these strips, we should be aware that they might make our teeth overly sensitive, especially to heat or cold. If we already have cavities, these strips are likely to aggravate them and make them worse.

The chemicals in whitening strips are mostly safe, but overdoing their use can inflame the gums. This happens because the strips usually come in a one-size-fits-all design. If they’re too big for someone’s mouth, they will also come into close contact with the gums.

Another issue with using teeth whitening strips is that they might not be able to penetrate every single curve and species within our teeth. This could result in patchy whiteness, yellow edges, and other weird results. Since the strips are one-dimensional, they won’t give a uniform whiteness to our three-dimensional teeth.

There’s also the fact that some health authorities categorize the use of hydrogen peroxide as harmful and toxic, especially when used in the mouth. This is because the chemical has the potential to damage the oral microbiome. This means that it does away with the good bacteria inside our mouth. Without the benefits of this bacterium, we’re more vulnerable to developing cavities, bad breath, gum disease, and other dental health issues.

How to Use Teeth Whitening Strips


The correct way to use teeth whitening strips will vary according to the brand you get, but most of the steps are fairly similar. If you want to minimize the risk and safety concerns, always read the instructions before using the strips. The following precautions are to be taken in any case:

  • Don’t brush your teeth before using the strips. This could increase their sensitivity afterward
  • There should be different strips for the upper and lower teeth. Make sure you use the correct ones on each area, or the strips might sit over the gums more than the teeth.
  • You can also cut large strips to make them more manageable for your teeth
  • There should be a plastic covering on the adhesive part of each strip. Peel it off before applying.
  • Be as gentle as possible when putting the strips on your teeth. Avoid the gums as much as possible.
  • The time period for letting the strips sit on the teeth is usually five minutes or less. Don’t exceed the time limit.
  • After removing the strips, rinse the mouth with a mixture of coconut oil and water.
  • After using the whitening strips, don’t brush the teeth for at least a couple of hours.
  • You can use teeth whitening strips up to twice a day. The box you have should tell you how many days the strips can last.


If we really want to whiten our teeth all the way round, it might be better to invest in a whitening procedure from our dentist. For quick fixes and gradual improvement, however, it should be safe to try out teeth whitening strips a couple of times. However, it’s still recommended to consult your dentist beforehand. You can also supplement the use of teeth whitening strips by investing in one of the best electric toothbrushes as soon as possible.
