Who is it for?

What are teeth whitening trays? Teeth whitening trays are a popular and easy-to-use option for whitening your teeth at home. These handy trays are designed to remove stains, plaque from tooth enamel and eliminate pigments on your teeth, helping you to get a brighter smile without the hassle and high cost of professional treatments. Let's take a look at how they work, what their benefits are and how to use them properly.

How do teeth whitening trays work?

The whitening trays are coated with a thin layer of whitening toothpaste gel, which is the main ingredient that whitens teeth. When the trays are applied to the teeth, the gel begins to penetrate the enamel, working on deep deposits and gradually whitening the teeth with each application.


Convenience: Teeth whitening trays offer a simple and convenient solution to brighten your smile. Unlike professional treatments, you can easily incorporate them into your daily routine without having to schedule appointments and without spending too much time in the dentist's office. It's a teeth whitening solution you can use safely in your everyday, at-home routine.

Cost-effective: Teeth whitening trays are a more affordable alternative to professional treatments, providing great results for very little money. Professional teeth whitening also uses a tooth whitening paste, or gel, similar to that used with tooth whitening trays, but in a lower concentration.

Diversity: There are different types of teeth whitening trays. Which will be more suitable for sensitive teeth, which will be more intense in their action or which will use more environmentally friendly materials. Meanwhile, others will contain peroxide, which is not allowed for sale and use without a dentist in the European Union at home in concentrations above 0.1%, such as Crest branded trays.

Efficiency: With regular use, you will see results within a few weeks. You can gradually achieve a brighter smile without compromising your budget, time or comfort.

Which teeth whitening trays to choose?

We recommend choosing teeth whitening trays that are suitable for sensitive teeth and with PAP technology, as they will be the gentlest and safest to use at home. If you feel that a particular plaque is causing discomfort, stop using it and choose a different brand or consult your dentist.

We recommend that you pay attention to whether the plaque contains peroxide, as the sale of tooth whitening products with peroxide concentrations above 0.1% is banned in the EU. Only under the supervision of a dentist can such products with higher peroxide concentrations be used. For example, most Crest tooth whitening trays are banned for sale in the EU because they contain peroxide levels of 14-15%. However, there are traders who still choose to offer these plaques, so be careful and choose safer options.

Correct instructions for use

First check the expiry date of the plates.

Brush and floss your teethA: Brush your teeth thoroughly, removing any dental debris or food particles that may interfere with the whitening process.

Apply the plates: Carefully place them on the upper and lower teeth, making sure they fit snugly and cover the desired area. When applying the trays, we recommend that you dry the tooth surface as much as possible to make them easier to fit.

Set the timer: Optimal results require a certain time frame, which should be indicated on the product packaging or on the trader's website. Set the timer according to the manufacturer's instructions and resist the temptation to remove the plates early.

Removal and rinsing: When the time is up, carefully remove the strips from your teeth and rinse your mouth and teeth thoroughly, lightly scrubbing away any whitening paste left on them. However, do not rinse your teeth completely to avoid irritating them too much.

Repeat the process: To get the results you want, continue to use the whitening trays several times and try to avoid lifestyles that make your teeth yellow, such as coffee, red wine or smoking.


Now that you are well informed about what teeth whitening trays are and how they can help you achieve a brighter smile, it's time to take action and try them out so you can judge how they have helped you. Remember to follow the instructions carefully and consult your dentist if necessary.
