Worldwide, dental caries are considered the most prevalent infectious disease. Approximately 91 percent of U.S. adults aged 20–64 had dental caries in their permanent teeth in 2011–2012. The most effective way to decrease the rate of dental caries is through effective oral hygiene. In addition, according to World Health Organization (WHO) and the World Bank, about 15 percent of the world's population (nearly 785 million people) have a significant mental or physical disability. There are currently 54 million people in the United States living with some type of disability. 17 percent of children under 18 have a developmental disability. One of the crucial and vitally important issues for these people is the oral health care and dental hygiene. On the other hand, it is estimated that the electric toothbrush market size can reach USD 5,852.2 Million by 2024.
