There are over 300 species of bacteria forming populations of several hundred billion in the human oral cavity. Using saliva and gingival cervical fluid as their main nutrients, these bacteria create their ecological niches on tooth and denture surfaces, gingival crevices, saliva, dorsum linguae, and buccal and pharyngeal mucous, threatening oral and systemic health. It is known that primary lesions of these chronic bacterial infections secondarily cause nephritis, arthritis, and dermatitis. Further, it has been demonstrated that bacteria inhabiting the oral cavity can cause pneumonia and endocarditis and that the periodontal disease associated bacteria become causative agents for blood circulation problems and coronary heart disease. It was found that <I>Candida albicans</I> and Staphylococcus species including methicillin-resistant <I>Staphylococcus aureus</I>, were highly accumulated on denture surfaces. <I>Streptococcus pneumoniae</I> and other opportunistic pathogens were also found in samples from elderly people requiring daily nursing care. In this article, the bases supporting the concept that oral health care, primarily mouth cleaning, including denture, is important not only to prevent oral infectious disease but also a healthy life for the elderly.
