Beconfident® Teeth Whitening Dual Boost X2 Refill is a teeth whitening gel for those who already have mouth trays. The patented Dual Boost X2 tooth whitening gel with its two active ingredients works in two different active phases for extra effective tooth whitening. In the first active phase, superficial discolourations are carefully removed from the teeth. In the second active phase, deeper discolouration is removed and the teeth are visibly brightened.

The X2 Refill kit also contains 10ml Tooth Gloss Mint that helps protect your teeth after treatment and gives extra shine. The gel is activated in two steps without causing any discomfort or pain, which is common in other teeth whitening products/procedures and especially those containing hydrogen peroxide. These can cause unpleasant tooth sensitivity and pain but our active ingredients are gentle and free from any side effects.

The treatment takes up to 10 days. Together with our Tooth Gloss that protects teeth from discolouration, this is our most effective and complete teeth whitening system ever!

Up to 6 shades whiter in 10 days

Over 500,000 happy customers!

Tested the products for a week
Tested the products now for a week - very pleased with the results and plan to use them in the future! Also received very good and quick assistance with questions I had about the products.
Easy to get in touch with them
Easy to get in touch with them, was a bit unsure how to use my product and got an answer after 3 hours. My teeth whitened in a nice natural way, and it didn't happen immediately either - clear recommendation.
It actually works!
It actually works! I ordered teeth whitening strips and teeth whitening pro kit and it actually works! Already after 13 days I can clearly see that my teeth have become significantly whiter. My family, who see me daily, have also noticed this.
Really happy with our toothbrushes!
Bought Sonic electric toothbrushes and their toothpaste in different flavours. It's been a long time since it felt so clean in my mouth. Also, the battery life is incredibly long. Cycled through Europe for 5 weeks without bringing the chargers and it lasted without problems. Really happy with our toothbrushes!
