Has anyone here had any experience with peroxide-free bleaching agents that you use for teeth whitening? I just read that there are some new EU regulations that prevent anyone except dentists and doctors from selling bleaching agents with peroxide in them, so there is a whole new market now with bleaching agents that supposed to be marginally less effective but much easier on your teeth and gums. I'm considering ordering some gel from a company that received very favourable reviews here in my country, but I'm not sure if it's worth it since I can just ask my dentist to send me some bleaching gel with peroxide in it.
