Name a common risk factor for periodontal disease.

Tobacco use is indeed a well-established common risk factor for periodontal disease. It has been extensively studied and shown to have a detrimental impact on oral health. The chemicals in tobacco can compromise the body’s immune response, making it more difficult for the body to fight off infection, including infections that affect the gums. Additionally, tobacco use can lead to reduced blood flow to the gums, impairing healing and increasing the likelihood of periodontal complications. The combination of these factors significantly heightens the risk of developing periodontal disease, making tobacco use a critical target for preventive measures in dental health care.

In contrast, regular dental check-ups, high calcium intake, and maintaining proper hydration are generally associated with good oral health practices and preventive measures rather than risk factors for periodontal disease. Regular check-ups help in early detection and management of issues, while adequate calcium and hydration contribute positively to overall health and oral hygiene.
