Oral health literacy is the degree to which individuals have the capacity to obtain, process and understand basic health information and services needed to make appropriate oral health decisions. The current review is based on some of the extensive literature in health literacy, much of it focused on the intersection of low literacy and the understanding of basic health care information. Health literacy is a non-pharmacological method of managing and preventing diseases. There are three distinct levels in oral health literacy, i.e. functional, interactive and critical. Health literacy is important for all adults, who must be able to read articles and magazines about oral and general health prevention, interpret instructions on prescription bottles and over-the-counter medications, manage the healthcare needs of their children and ageing parents and interpret insurance and Medicare rules, regulations and benefits. There are several factors which impact on low health literacy level in the community. Poor health literacy is considered as a contributor of poor oral health status in an individual, poor heath outcome in a community and health inequalities. The dental profession is indeed changing the tide and now recognizes that several solutions can be implemented to ensure effective communication becomes a national organizational priority to improve oral healthcare.
