Periodontal (gum) diseases are a major threat to oral health, causing tooth loss and being the main cause of tooth loss in Western Europe. Despite the availability of advanced healthcare services, the prevalence of periodontitis has remained largely unchanged over the last 25 years. The evidence shows that periodontitis is associated with various non-communicable diseases, including diabetes and cardiovascular diseases. However, recognition of these mutual risk factors and knowledge sharing between dentistry and general health are scarce in clinical practice. Poor oral health is also strongly associated with lower socioeconomic status. The report recommends a societal approach to good oral health, including filling the gaps in knowledge and awareness, and improving access to dental care for vulnerable populations.
