Night serum for teeth whitening, Beconfident, 10 ml Teeth Whitening Night Serum repairs enamel and whitens teeth while you sleep. Thanks to the innovative formula, it helps strengthen and fill micro-cracks in the enamel during the night, while simultaneously removing discoloration and tartar.

The serum contains hydroxyapatite and will support the natural repair process during the night. Even incipient caries can be repaired. Daily brushing with a toothpaste containing hydroxyapatite also helps to seal the so-called dentinal tubules. In the case of teeth with an exposed neck, the sensitivity to pain associated with thermal and chemical stimuli can be significantly reduced. Peroxide of 0.1 is used for teeth whitening at home.
