Adequate knowledge of oral health is important due to its influence to better oral health and in developing healthy oral health practices.

The questionnaire included questions on demographic characteristics; questions about oral health practices; nutrition; knowledge of dental and oral health; and risk factors such as smoking and water pipe use. <b>Results:</b> Respondents in Kuwait demonstrate good oral health knowledge; however, daily dental flossing is inadequately practiced. Nutritional practices such as fast-food consumption and sugary sweet consumption are common amongst the employed adults. Males and smokers have poorer knowledge and inadequate oral hygiene practices.
