Explore our selection of the best whitening kits for a healthy, bright smile.

Having pristine white teeth is everyone’s wish, but it’s not always (in fact, almost never) possible to show off a bright, unblemished smile by relying only on regular daily cleaning. Circumstances such as smoking, age, abuse of particularly coloring substances cause the teeth to be covered with a more or less visible halo, which, however, makes the whole thing unaesthetic and is also able to affect the perception of one’s image.

It is no coincidence that one of the most frequent aesthetic treatments is teeth whitening, which is used to achieve a long-lasting and well-cared-for overall appearance.

This practice is usually carried out in a dental office and involves the use of specific equipment, but it is also possible to rely on special sets with which you can make a DIY whitening.

In detail, these products are able to restore the teeth to their original brightness through treatments that, depending on their degree of invasiveness, act both on surface stains and deeper stains, the latter can be caused for example by extended use of certain medications.


Therefore, if you too are interested in purchasing a teeth whitening set, take a look at this article to learn all the details of this treatment and to choose the product that could prove to be the most effective for your needs,
Then flaunt your most beautiful smile without necessarily going to the dentist, but using only the kit with the best value for money!

The 7 best DIY teeth whitening kits for different needs

When it comes to teeth whitening, we usually tend to think only of the aesthetic aspect of this treatment. However, before purchasing a whitening kit, it is important to check if there are any problems that may affect your teeth and gums, such as tooth decay, tooth sensitivity, or infection. In these cases, you should refrain from using certain products and visit your dentist for the primary resolution of these conditions.

Back to us: if going to the dentist for whitening proves to be expensive or inconvenient depending on your schedule, you can rely on DIY whitening kits, but it is good to know that not all products are equal and that there are some that are characterized by the particular convenience of use, but without going to the expense of effectiveness.

How exactly do teeth whitening kits work?


best teeth whitening kits for sensitive teeth 2021


Although there are several alternatives on the market to make your teeth white without necessarily having to go to the dentist, the kits equipped with LED light and a special whitening gel appear to be the most sold as well as the most effective.
As you can see from the list of products selected and proved to be the best according to different selection criteria of both aesthetic and functional type, each kit is characterized by a more or less rich package of accessories. However, regardless of this aspect, their operation is in fact very similar and particularly simple.

The Gel

In detail, home whitening involves the use of a gel composed of substances capable of acting on tooth enamel and eliminate stains or halos that make them more yellowish. Generally, the main ingredient of the whitening gel is hydrogen peroxide, which is the basic element of hydrogen peroxide and is also used by dentists for professional bleaching.

However, there are also gels available that do not contain hydrogen peroxide and that are characterized by a composition based on sodium bicarbonate, lemon extracts, and other natural raw materials, which makes them better from the point of view of dental health. In fact, hydrogen peroxide is often considered an ingredient that should absolutely not be used on teeth, since it carries out a particularly aggressive corrosive action, leading in the long term to problems of sensitivity, but we will analyze this aspect better in the following paragraphs.


Led light

Returning to the operation of these sets for teeth whitening, in addition to the gel is a lamp with LED light usually placed on a splint and to be inserted into the mouth. The light plays a key role in this operation, as it allows the activation of the molecules that make up the gel, making it more effective.
With LED light, the whitening solution penetrates better under the stains and removes them much more quickly.
In the past, UV lights were used, but over time they proved to be unsuitable and ineffective. Today, with new technologies, it is possible to use LED lights of varying power, but in any case safer for the patient’s health.

To obtain the desired results in terms of brightness and teeth whitening, it is necessary to follow a treatment that turns out to be minimally invasive and easy to perform. Usually, it involves applying the gel and keeping it on the teeth for a variable time for once or twice a day (depending on the type of product). The treatment lasts about 2 to 3 weeks and can offer results that last up to a year.
In addition, to verify the effectiveness of the treatment, a convenient color scale is provided with which to compare the shade assumed by your teeth as you proceed with the whitening.

All in all, the whitening kits are attracting more and more interest from the public because they allow you to have white and clean teeth, so desired, with ease and at a cost much lower than the sessions at the dentist.
In any case, the price is not only the only parameter to take into account when buying, but it is necessary to give importance to the quality of materials and substances used to avoid more or less permanent damage to teeth and gums.

How to choose the Best Teeth Whitening Kits 2021

best teeth whitening kits for sensitive teeth


Due to the increasing demand for do-it-yourself teeth whitening products, pharmaceutical companies have developed and marketed several home whitening kits, intended as a viable alternative to dentist sessions.
Among the different brands and manufacturers, it is not always easy to choose the product that really works and is best for your personal needs. As a matter of fact, a high price is not always synonymous with quality, just as an excessively low price could be related to a product that is detrimental to dental health.

For this reason, although budget is one of the parameters that you undoubtedly need to consider, it is not the only one on to base your purchase on. In fact, in order to be sure about the reliability of the product, it is good to investigate some information that, together, can help you in your choice. Here then is a list of elements that you need to evaluate before proceeding with the purchase of a teeth whitening kit.

1. Manufacturer

The manufacturer has a great impact on the quality of a whitening kit, as many of the products on the market are made in China or come from companies that are not very well known. Therefore, it is necessary to find out about the various brands and, above all, about their reliability in the field to which they refer, in order to have certified products and customer service easily available in case of doubts or problems.

2. Ingredients

Even if you are not a chemist or are not familiar with the names of substances, once you have identified the kit that most interests you, it is good to dwell on the list of ingredients that make up the whitening gel. This operation can make a real difference in the choice of the product because in many cases chemical substances are used that are dangerous for the teeth and for health in general (especially in the case of unfamiliar brands and excessively low prices).
For completeness, avoid kits that include high concentrations of hydrogen peroxide, baking soda, and lemon.

3.Customer Reviews

Especially for online purchases, it is of particular importance to dwell on the reviews provided by those who have had a chance to buy the product. Don’t just read the positive notes, but head especially for the negative reviews, where they exist. In this way, you have the opportunity to take stock of the overall quality of the kit and evaluate for yourself the pros and cons that distinguish it.
Today, many purchases are made on Amazon, but don’t limit yourself to the reviews you find on this platform; do a wider search and you’ll be able to find forums and discussion groups on which you can also compare yourself.

4. Price

As mentioned, the price does not always correspond to the quality of a product, but it is undoubtedly a parameter to consider when talking about the convenience of a home whitening compared to a professional one.
In order to get an idea, it may be helpful to have a look at online price comparators which, taking into consideration different kits, provide a general overview of the greater or lesser economic competitiveness, taking into account the characteristics and quality of each one.

5. Personal needs

Last but not least, dwell on your personal needs. Do you have sensitive teeth? Do you have little time to devote to treatment each day? Would you like a kit just to reinvigorate the shine of your teeth between dental appointments or a product for longer-lasting whitening? Here, are some of the questions you’ll need to ask yourself in order to select the products that are best for you.


 Any Risk using tooth whitening kits?


best teeth whitening products for sensitive teeth 2021


By themselves, the tools that make up the kits are not dangerous to health; we have seen in the previous paragraphs how the LED light of the lamps is more effective and safer than UV lights.
What we need to focus on in terms of health risks is instead the whitening gel.

Kits with particularly aggressive gels can in fact cause in the medium to long term problems of tooth sensitivity and pain. Substances such as hydrogen peroxide, if used in high concentrations, corrode a lot of the tooth enamel and can irritate the gums if they come into contact with them.
These inconveniences can also occur during a whitening at the dentist’s office, of course, but in this case, special mucous membranes are used to protect the soft tissues and there is undoubtedly the continuous assistance of a professional.

At home, however, especially if the treatments are not performed properly, it is possible to run into very aggressive products for the mouth in general and that creates more or less important annoyances. In fact, there are specific regulations that indicate the maximum concentration of peroxide and other substances in whitening gels.

Although natural gels should be preferred and those with chemical substances in them should be discarded, the same abrasive effect is also determined by sodium bicarbonate and lemon extract, which are real enemies for sensitive teeth.


What are the alternatives to tooth whitening kits?

best teeth whitening products for sensitive teeth


Not only kits, but dental health also passes through the use of other products that are able to make teeth shinier. Whether for health or aesthetic issues, the frenzy to have a bright, snow-white smile has led to the marketing of several products.
In fact, although whitening sets give the most effective results, you can also take advantage of other methods to perform DIY whitening. Here are a few of them:

1. Whitening pens

More compact than complete kits, whitening pens already have the recommended amount of gel inside to apply directly to the teeth. They are extremely easy to use and carry around, require no refills, and can be used to remove individual stains in a targeted manner. However, they have limited effectiveness and do not always give the desired results.

2. Whitening strips

These are adhesive strips that are applied directly to the teeth and need to be held on for about thirty minutes a day. In addition to adhering to the dental arches, these are composed of abrasive chemicals that are able to achieve medium-low teeth whitening in the treatment of about 2 weeks.
They have the advantage of being very comfortable to use and do not cause much damage to tooth enamel.

3. Whitening toothpaste

The use of toothpaste is essential to maintain proper dental hygiene, but on the market, there are products that, in addition to cleaning, also provide a certain whitening effect. This is done by adding micro granules and specific ingredients to the normal paste.
Whitening toothpaste allows for a sort of superficial whitening of the teeth, not a true and proper whitening, and, in the long run, can have a corrosive effect on enamel.

4. Activated carbon

Available both as an ingredient in toothpaste and as a paste or powder, activated charcoal has made the headlines as a good and natural method of DIY teeth whitening.
Indeed, in its powdered form, activated charcoal has a sort of abrasive effect when rubbed on the teeth and removes surface yellowing and bad breath. On the other hand, it is not effective against deeper stains or stains caused by the use of certain medications and requires care during use as it may excessively corrode the enamel.

5. Home remedies

Among the most popular natural remedies for whitening teeth at home are baking soda and lemon. Both must first be diluted in water and then dip the toothbrush and rub it on the teeth. Surely these are natural products that give freshness to the breath and make teeth smoother and shinier, but it is not recommended to use them in the long term as they can easily cause sensitivity problems.

What is the whitening capacity of the kits?
Depending on the quality of the product and treatment, the kits are able to restore the natural color of the teeth and remove surface stains due to smoking and diet. If you want to lighten your color by several degrees, you need professional whitening.
Are there any contraindications for the use of the kits?
The use of tooth whitening kits is to be avoided if you already suffer from tooth sensitivity, as the gel may aggravate this problem. In addition, it is not recommended to use these products during pregnancy and in case of intolerance to any ingredient.


How long does the whitening effect last?
