The best LED teeth whitening kits - Top 5 2025
Teeth whitening with the LED lamp was until recently only available in dental practices. More and more manufacturers are offering LED tooth whitening kits that can be used at home. This solution is painless, simple and safe, and thanks to the high-frequency blue light that activates the whitening gel, satisfactory results can be achieved. The process of teeth whitening with the LED lamp involves applying the gel to the teeth and using special flexible trays that remain in the mouth for about 15 minutes. Many of the best lamp teeth whitening devices have built-in timers and wireless charging options for added convenience. Investing in an LED teeth whitening kit is an investment in a beautiful and white smile without the need to visit the dentist. In the ranking below, you will find popular LED tooth whitening systems that we have taken a closer look at in our tests.

Take a look at our ranking of the best at-home teeth whitening kits:
The Light & Bright system from Smilebite is an effective and convenient way to whiten teeth at home. Testers noticed a visible whiter teeth effect after the first few uses and were very pleased with the enamel- and gum-safe composition of the whitening gels - indeed, it does not cause sensitivity. The lamp teeth whitening device is equipped with a timer that tells you when the recommended use time has ended, allowing you to carry out other activities without having to control the time yourself. The device's dual LED light technology enhances whitening efficiency and the wirelessly rechargeable battery lasts for approximately 10 sessions. The ergonomic tooth tray moulds to the shape of the mouth and the whole kit is aesthetically packaged. Testers felt that the Light & Bright was worth the money and definitely deserved to be named a ranking winner. And if you need to continue treatments, the manufacturer offers additional gels, so the kit will not go to waste after the first whitening cycle.
Ivismile's cordless LED light at-home teeth whitening system offers a safe, convenient and fast way to a brighter smile. Testers appreciated the beneficial composition of the included whitening gels, which contain a high amount of natural plant extracts. An additional advantage of the kit is the built-in timer, which makes it very convenient to use. Unfortunately, some testers complained about the mismatched caps, which do not sit perfectly on the teeth and require some effort to place them correctly. Additionally, the taste of the whitening gel was not to the liking of most, and the gel pens run out quickly. However, the price of the Ivismile kit is affordable, although you may need to buy more gel packs to get the best results, which increases the overall cost of whitening.
Smilepen's Whitening Kit for at-home teeth whitening received high praise from our testers. It proved easy to use and the whitening effects were noticeable after just a few days of regular use. Testers were also pleased with the simple and enamel-safe formulation of the whitening gel contained in the three included pens, which last for a fortnight of use. However, testers complained about the way the gel pens are used for the first time, as it requires dozens of presses to get the gel out, which is quite cumbersome. On subsequent uses, this problem fortunately does not occur. The effects are noticeable, but the kit is very expensive. However, the most commonly reported difficulty is the requirement for the LED light cap to be plugged in at all times when the device is in operation. In practice, this is very inconvenient and limits mobility during treatment.
Smile Charge by Garett Beauty is a teeth whitening device that uses modern LED technology with two colours of light - blue and red. As a result, the substances in the whitening gel are activated just like in the dentist's office, speeding up the time of one treatment to just 10 minutes. Our group of testers appreciated the convenience of use thanks to the built-in rechargeable battery and the applicators with convenient brushes, which make it easy to apply the gel accurately to the surface of the teeth. Testers noted the rather high price and poor availability of the product. In addition, the tooth cap was uncomfortable for some users and did not fit well into every bite. Despite these inconveniences, Smile Charge has visible application results, but those with wider jaws will find it uncomfortable to use.
The whitening kit with toothpaste and LED lamp by Blanx received mixed reviews from the test group. The group participants appreciated the convenience of use and the low price of the kit, but the whitening effects required time and regularity, which meant using the toothpaste three times a day and irradiating the teeth at least once a week. Testers noted that the kit failed to deal with severe tobacco and coffee stains, which was a significant drawback. The product is affordable, but testers unanimously agreed that its effectiveness was not up to par with more expensive alternatives on the market. As a result, the BLANX WHITE SHOCK TREATMENT + BLANX LED BITE set proved to be a moderately effective solution, recommended rather for milder cases of discolouration. The product is cheap for an LED tooth whitening kit, but unfortunately this is not the case when you get good efficacy at a low price.
