Traditionally, children's toothpastes contain fluoride to counteract demineralisation and tooth decay. However, for children up to age 6, European Directive 2009/129/EC places restrictions on toothpaste containing fluoride (in concentrations from 0.1 to 0.15%), stating that it should only be used in small quantities and under the supervision of an adult. In addition, the European Union has clearly established that the minimal fluoride amount causing fluorosis is equal to 0.08-0.1 mg/kg/day. This is to prevent excessive absorption of fluoride, which is already naturally present in water and in many foods, and which can be the cause of fluorosis: a condition that in its mild form can cause slight discolouration of the enamel, and in its severe form can even cause the teeth to fracture. All the Biorepair range is totally devoid of fluoride and contains more than 20% microRepair®: hydroxyapatite crystals made of the same material as teeth and which, at every use, adhere to the enamel surface, remineralising it and protecting it like a shield. In addition, Biorepair performs an effective antibacterial action thanks to its prolonged release of Zinc Ions. The innovative Biorepair formula, gentle and totally free of fluoride, makes it safe for use by children under 6 even without adult supervision.
