Finding a good teeth whitener is difficult, in my experience at least!I have now tried a lot of them and wanted to give you my recommendations.Here comes the top three:1. beconfindent✅ EU Approved & Peroxide-freeIn first place we find the Dual Boost X2 Kit from Beconfident. This is a powerful gel that clearly gives satisfactory results.Shade differences after about 2 weeks of use, which is approved.This whitening is often called an "advanced teeth whitening" as there are several steps in the process itself.2. Dentaworks✅ EU Approved & Peroxide FreeThe next best option for teeth whitening at home is the teeth whitening pen from Dentaworks.This is a method that has become increasingly accurate, although you usually get better results with a teeth whitening putty - the pen is much easier to use.With the pen you can reach everywhere & you brush about 1-2 times a day (for best results). Shade differences take effect already after a few days.3. dentaway✅ EU Approved & Peroxide FreeIt's not surprising that teeth whitening treatments can differ - after all, content and procedure can lead to varying results.However, I really didn't expect the results to be this tangible.After the test, I could easily conclude that the Starter kit from Dentway produced the most shade differences.Due to my love for beconfident I can only highly recomend it!
