GC Tooth Mousse reverses whites spot lesions, and helps with sensitivity after tooth whitening. Tooth Mousse comes in two version, with fluoride (PLUS) and without fluoride (ORIGINAL). How Does GC Tooth Mousse Work It contains 10% Calcium Phosphopeptide - Amorphous Calcium Phosphate (CPP-ACP) and 0.2% Sodium Fluoride(NaF). Combined together they form CPP-ACPF(casein phosphopeptide – amorphous calcium phosphate fluoride). When applied in the mouth CPP-ACP binds to the tooth, and plaque and soft tissue surfaces localising calcium, phosphate and fluoride. GC Tooth Mousse also helps stimulate saliva flow. The longer CPP-ACP and saliva are maintained in the mouth, the more effective the result. Tooth Mousse provides extra protection for teeth. It helps to neutralise acid challenges from bacteria in plaque or other internal and external acid sources.
