The primary cause of gingivitis and most forms of periodontal disease is dental biofilm. Dental biofilm, also known as plaque, is a sticky, colorless layer of bacteria that forms on the surfaces of the teeth and gums. When plaque is not regularly removed through proper oral hygiene practices, it can harden to form tartar (calculus), which further contributes to inflammation and infection of the gum tissue, leading to gingivitis. If untreated, this condition can progress to more serious periodontal diseases, which can impact the supporting structures of the teeth and lead to tooth loss.

While chronic stress, hormonal changes, and dietary deficiencies can contribute to oral health issues and may exacerbate existing conditions, they are not the primary cause of gingivitis and periodontal disease. Chronic stress may affect the immune response and lead to neglect of oral hygiene, hormonal changes can affect gum tissue sensitivity, and dietary deficiencies can impact overall oral health but do not directly initiate the disease processes as dental biofilm does. Maintaining a consistent oral hygiene routine to remove dental biofilm is crucial in preventing gingivitis and periodontal disease.
