Dental plaque once it reaches a critical thickness, acts as a reservoir for both aerobic and anaerobic pathogens. Failure to remove plaque begins a complex cascade of biological activity by which pathogens adhere to mucosal and tooth surfaces and pathogen overgrowth ensues. Additionally, neglected or insufficient mouth care is the foremost predisposing factor to oral conditions such as gingivitis, mucositis, and stomatitis which supply additional ports of entry for pathogens.
