The health of younger generations is an important factor and a precondition for the well-being of society and its progressive development. It has long been known how health affects the quality of human life. Korczak Janusz (outstanding Polish teacher, writer, doctor and public figure.) wrote: "Health is the main good of life." The state of the oral cavity is very closely related to the well-being of the human body as a whole. Dental caries and diseases of the mucous membranes of the oral cavity reduce the quality of life, negatively affect the condition of the digestive system, impair the appearance and overall health of the person. Prevention of oral diseases and training in proper hygiene is the first step towards a beautiful smile and the improvement of the whole body.
