10 best teeth whitening kits and complete guidelines

The Best Teeth Whitening Kits Dentists Recommend: At-home kits use a whitening gel and, typically, an LED light source to help you achieve whiter teeth from the comfort of your home and at a more affordable price. With this method, you will not have to wait for your next appointment with your dentist. Simply open the box, follow the product instructions, and enjoy the results: a white, healthy smile that will radiate joy and confidence.

For all these reasons, we have spoken to our experts to determine which are the best teeth whitening kits on the European market and help you get the best option for your needs and budget.

Our smile needs to be maintained to look better and brighter. Of course, dentists perform in-clinic teeth whitening treatments in a matter of minutes, but they are expensive.

The good news is that there are many effective, low-cost options you can try from home when an appointment isn’t possible (or out of your budget). Read on for dentist-approved recommendations and more of the best teeth whitening kits to try at home.

What is a teeth whitening kit?

Since we have mentioned whitening kits, we will tell you what they contain and what each component is used for, whether they are professional or homemade.

A whitening kit is a package consisting of a splint in the shape of your teeth (or a generic one if purchased outside the dental clinic) and a whitening product that must be applied to it to put it on your teeth for a while at home. It is simple and comfortable to manipulate, but we always recommend that you do it under the supervision of a dental aesthetic professional: this way your teeth will look whiter and healthier most safely and effectively.

How does a teeth whitening kit work?

A teeth whitening kit works by applying a whitening gel to your teeth. This gel contains a whitening agent, such as carbamide peroxide or hydrogen peroxide, that helps remove stains and discolorations on your teeth.

Typically, customizable teeth whitening trays are used that adapt to the user’s teeth and are filled with the whitening gel. The tray is placed in the mouth and left for a set time, which may vary depending on the kit and manufacturer.

Some teeth whitening kits also include an LED light that is used to activate the whitening gel, speeding up the whitening process. After completing the treatment, the trays are removed and the mouth is washed to remove any gel residue.

It is important to follow the instructions carefully and not exceed the recommended time of use, as this may cause gum irritation or tooth sensitivity. With proper and regular use, a teeth whitening kit can help you achieve whiter, brighter teeth.

What are the advantages of teeth whitening kits?

Whitening kits are a composition of teeth-whitening items and their advantages are:

*Fast Results: With a teeth whitening kit, you can get visible results in just a few days, unlike other treatments that can take weeks or even months.

*Easy to use – Most teeth whitening kits are very easy to use, meaning you don’t have to be an expert to get professional results.

*Affordable – Compared to in-office teeth whitening treatments, teeth whitening kits are much more affordable and can provide similar results.

*Customizable – Some teeth whitening kits come with customizable trays, meaning they fit perfectly to the shape of your teeth, ensuring uniform application and optimal results.

*Removes stains and discolorations: A teeth whitening kit can remove stains and discolorations caused by tobacco, coffee, tea, wine, and other foods and drinks that stain teeth.

*Improves Confidence: Having a whiter, brighter smile can boost your self-confidence and make you feel more confident in social and professional situations.

*Non-invasive – Unlike other teeth whitening treatments, teeth whitening kits are non-invasive and do not cause pain or tooth sensitivity.

In short, a teeth whitening kit is an easy, affordable, and effective way to improve the appearance of your teeth, giving you a whiter, brighter, and more confident smile.

Risks of teeth whitening kits

First of all, you should keep in mind that many of the kits sold online do not comply with the general standards established by government agencies for their manufacturing and distribution. If we look closely, there is no list of ingredients, instructions for use, or expiration date on the packaging.

Therefore, since these are unproven treatments that do not have a scientific basis, they cannot be considered effective. However, the companies that market them insist on selling them through false evidence that supposedly demonstrates their effectiveness.

Among the main risks of this type of treatment is the high content of hydrogen peroxide, that is, the whitening agent that allows teeth to be whitened. A priori, it may be thought that thanks to this high level of the component the desired results will be obtained in less time, but the truth is that non-professional use of it can produce effects such as hypersensitivity in teeth and gums and even much more harmful damage. The high concentration of hydrogen peroxide can cause burns and gum irritation, especially when the splint included in the kit does not adapt correctly to the size and shape of the dental arch of the person who will use it.

As for the teeth, it can cause certain damage such as grooves on the surface of the teeth and weakening of the enamel, causing exposure of the dentin. Furthermore, if the person using this treatment suffers from cavities, they may end up penetrating the inside of the tooth, causing very intense pain.

In the most extreme cases, it can cause burns so damaging that the only solution would be to place a dental graft.

To avoid all the risks mentioned, you must remember that to purchase a whitening kit you must be guided by expert dentists. They will offer you the best solutions such as effective pharmacy whitening kits that have the concentration of hydrogen peroxide necessary for use or performing a whitening treatment at your trusted dental clinic.

Tooth whitening kit for yellow teeth

If you are worried about yellow teeth, a tooth whitening kit may be a good option for you. This type of kit can help remove stains and discolorations on your teeth, leaving them whiter and brighter.

Once you have determined that you are ready to use a teeth whitening kit, it is important to follow the instructions carefully and not exceed the recommended usage time, as this can cause gum irritation or tooth sensitivity.

It is also important to note that a teeth whitening kit is not a permanent treatment and that it may be necessary to repeat the process from time to time to maintain the results. Additionally, it is important to maintain good dental hygiene and limit the consumption of foods and drinks that can cause stains on teeth, such as coffee or red wine.

Overall, if you are looking for an effective way to treat yellow teeth, a teeth whitening kit may be a good option. However, it is important to follow the instructions carefully and talk to your dentist if you have any concerns or questions.

How to choose the best teeth whitening kit

What is a teeth whitener used for?

A complement to daily brushing is a teeth whitener, which focuses on removing superficial stains from the tooth enamel. In this way,  the natural color is recovered and a clearer and brighter smile is achieved.

Teeth whiteners use specially enhanced gels due to the effects of direct light to eliminate stains. The consumption of tobacco, coffee, wine, or environmental pollution itself, discolors the teeth and generates an unpleasant appearance.

How to use bleach?

To use a teeth whitener, it is imperative to distinguish between the different possibilities available on the market:

The only thing you have to do if you use powders, such as activated charcoal, is perform a standard cleaning once applied to your toothbrush. You can rinse by brushing at the end, with toothpaste and remove any residue with the best mouthwash.

As in the case of the IWhite Instant Kit, the second alternative is the molds with the gel incorporated. You just have to remove the molds from the box to use them and insert a panel in each part of the mouth. So that the gel does not come out of the structure, try not to bite the panels.

Whitening kits with LED lights are your third option. In this case, you will have to follow the following steps:

*For a few minutes, place the dental mold in warm water.

*Apply the whitening gel to the inside of the mold with the syringe.

*Via USB Connect the mold to your mobile phone or laptop.

*In some models, light is combined with vibration for greater effectiveness. Let the light activate and the device do its job.

*You will only have to add the gel with the syringe and press the power button if the device works with a round battery.

Parts of a teeth whitening kit:

The dental mold or tray:

The molds are impregnated with whitening gels and attached to the structure of the mouth to complete the treatment. It’s like the protectors that boxers use.


Inject the gel with the appropriate active ingredient into the syringe to remove surface stains. Care must be taken to apply the product so that it is evenly distributed throughout the mold structure.

Whitening gel:

It contains the elements that will be applied to the enamel to recover its natural color. It can be incorporated into the mold, in the syringes, or separately.


There are different options. When the gel is incorporated into the mold, it may not be necessary. This could be a circular battery on the back of the device that powers the LED light, or a USB or micro-USB connection to integrate the whitener with your phone, tablet, or laptop.

What should you keep in mind before buying a bleach?


If you are going to trust a whitening kit you have to look for the one that offers the best benefits to get rid of those annoying stains on your teeth once and for all.

A model that combines the action of LED light with vibrations will be the most recommended. In this way the process is accelerated and intensified, being able to see positive results more quickly.

Easy to use:

You will need a model that is easy to use if you are facing your first experience with a teeth whitener. You can choose whitening products that come in gel form because you simply have to take them out of the container and put them in your mouth.

The sensitivity of your teeth:

It can be very uncomfortable if you have delicate teeth or sensitive gums to wear a plastic or silicone mold on your jaw. You should look for a kit with a soft material if you fall into this group or opt for activated charcoal whitening powders.

Types of whitening kits

Currently, you can purchase a professional whitening kit in a dental clinic, or the so-called ‘homemade’ ones, available in large stores, pharmacies, or specialized cosmetics sales chains. Those dispensed by dentists are always more effective, powerful, and safer than those purchased in specialized stores or pharmacies.

Unlike the first, home whitening kits ignore the prior care and advice that a professional gives you before applying treatment, which can end up harming your teeth, in addition to the fact that the products used are much less effective than those used. in clinic. Here you can find more information about the whitening kits currently on the market.

Tips for teeth whitening kit

Whichever kit you choose to purchase, you should keep the following in mind:

*If you consume drinks or foods that are pigmented or have coloring (such as tomato sauce, red wine, citrus fruits, coffee, and many others), you should rinse your mouth after finishing. This way you prevent your teeth from staining and prolonging the duration of the treatment.

*Clean your teeth at least three times a day and brush after eating foods high in sugar or any ingredients that can stain your teeth.

*Try to apply the whitening gel in the kit according to the instructions given by the product and within the established time. That is, if the treatment indicates that you should apply it for 20 minutes, you should do it for that time.

*Reduce alcohol and tobacco consumption in the days after treatment, otherwise the results will not be long-lasting.

*Floss once a day to maintain the health of your teeth and mouth in general.

*Schedule a dental cleaning every six months so your dentist can remove tartar that builds up on your teeth.

*Do not consume snacks or sweets with a high level of sugar and colorings. And if you do, follow the previous advice: rinse your mouth after doing so so that your teeth do not stain.

Avoid foods that stain

*Berries and fruits: Although the antioxidants in berries provide health benefits, their intense tone can cause stains. Fruits like lemons are also harmful to teeth due to their acidity.

*Sauces: Brightly colored sauces, such as curry (turmeric-based) and tomato sauce, can also contribute to stains, and the acidity of tomatoes makes them doubly guilty. Opt for a lighter, creamier version to reduce the chances of staining your teeth.

*Coffee: The dark color and acidity of coffee have a detrimental effect on teeth.

*Tea: Black tea, in particular, can be more harmful than coffee. Even the lightest infusions can erode enamel and cause staining.

*Wine: The tannins in red wine are responsible for teeth taking on a gray tone. White wine, for its part, although it is not directly responsible for stains, can darken existing ones.

*Sugary drinks: It’s well known that sugary sodas cause cavities, but because they do so by wearing down that shiny tooth enamel, your teeth will also look darker over time.

*Smoking: Nicotine and tar from tobacco can stain teeth very quickly, even vaping can cause stains on teeth. Over the years, heavy smokers may see their teeth turn brown, known as smoker’s teeth.
