It contains 10 ml Peroxide Free Triple Boost Max Gel, which is designed to be used together with thermoform mouth trays but can also be applied with the finger tip onto the teeth surface. The Pro Refill also contains a Protect & Repair gel which is used post whitening for protection and strengthening of teeth. Working mechanism in short: The Triple Boost Max gel - The gel contains PAP (ε-phthalimido peroxy hexanoic acid) + sodium bicarbonate + coco sulfate which work together for the most effective peroxide free whitening treatment available. The PAP ingredient is an organic peracid resulting in a high degree of oxidation. Oxidation is necessary for the bleaching procedure as it neutralizes organic double bonds that cause dental discolorations. However, the activity of PAP is not based on the release of hydrogen peroxide and the gel is 100% peroxide free. A fourth whitening effect can be created with the Beconfident® LED light which accelerates the result significantly using ferrous gluconate activator and blue light radiation. The Protect and Repair Gel (10 ml tube) The enamel consists of about 97% of hydroxyapatite, which is why we added Hydroxyapatite to support the repair process after whitening. Even incipient caries lesions can be repaired. Daily brushing with a hydroxyapatite-containing toothpaste also helps to seal the so-called dentine tubules. In the case of exposed tooth necks, the pain sensitivity associated with thermal and chemical stimuli can be significantly reduced. The gel also contains a sodium salt called Tetranatrium pyrophosphat that helps to dissolve the discoloration of the teeth and to remove them more easily. Furthermore, the pyrophosphate has the property to restrict the formation of tartar. It also contains sorbitol which has moisturizing characteristics and Sodium Fluoride to prevent caries. The Chamomile is an extract from the flowers of chamomile which has a soothing effect on the gums. The gel contains Sodium monofluorphosphate (920 ppm F-).
