One major impact of smoking on oral health is that it increases the risk of periodontal disease and oral cancer. Smoking has been rigorously studied and shown to be a significant risk factor for both conditions.

Tobacco smoke contains harmful chemicals that can impair blood flow to the gums, leading to the weakening of the periodontal tissues. This can cause inflammation and infection, ultimately resulting in periodontal disease, which involves gum tissue destruction and loss of bone surrounding the teeth. Furthermore, smoking is a well-established risk factor for oral cancer due to the carcinogenic substances present in tobacco. The exposure to these substances can lead to the development of cancerous lesions in the mouth and throat.

Understanding this critical impact highlights the importance of smoking cessation programs in dental hygiene practice, as reducing smoking rates can significantly improve oral health outcomes and overall health.
