Stating that many people turn to bad or negative habits that affect oral health, such as tobacco or alcohol, together with stress, experts said, “The risk factors of tobacco and alcohol can affect the formation of periodontal disease.” They point out that during periods of stress, the hormone cortisol rises, which can cause periodontal disease.
