In Portugal, 59 per cent of 6-year-olds have tooth decay and 47 per cent of 6-year-olds brush their teeth only once a day. 63% of families with children under 6 have never visited the dentist. It is in the face of this reality that Aprender a Ser Saudável was born, because we believe that all children have the right to grow and develop in a healthy way, which is why it is essential to support the education of the child population. The project thus aims to promote oral health and healthy eating among kindergarten and primary school children attending school groups located in priority territories in the Municipality of Porto, in order to help reduce the prevalence of oral diseases.
