Beconfident® X1 Start Kit gives you a peroxide-free teeth whitening for that beautiful white smile without any side effects like pain in the gums or tooth sensitivity. The Start Kit contains everything you need and is perfect if you’ve never whitened your teeth before. It’s very easy to use and each treatment only takes 15 minutes. You can easily mould the included mouth trays for an individual fit – just like at the dentist. The whitening effect of teeth comes from a resolution of surface stains, partly through the oxidation of organic compounds deep seated in the enamel and dentin. Beconfident’s method is based on a combination of cleaning agents (Surface Active Agents) and active 32% sodium bicarbonate. Unlike hydrogen peroxide, which can cause unpleasant tooth sensitivity and pain in the teeth, ours is gentle and free from side effects. All that is needed to get your dream smile is included in the package; 10ml peroxide free whitening gel with fresh melon flavour for 10 treatments. 3pcs (one extra) mouth trays that keeps gel in place, a shade guide and clear instructions in English. Up 4 shades whiter 10 days. Advanced whitening: Effectively removes stains and restores the natural whiteness of teeth.
