Answer:
Gingivitis, Periodontitis, and Necrotizing ulcerative gingivitis.
Explanation:
Gingivitis - gums are mildly inflamed, may appear red or swollen and may bleed during brushing. Periodontitis - gums begin to separate and recede from the teeth. This allows plaque to move toward the roots, supporting fibers and bone. Necrotizing Ulcerative Gingivitis - supporting fibers, bone is destroyed and necrosis of the gum and surrounding tissue is seen.
Other possibly contributory lifestyle factors include alcohol consumption, stress, diet, exercise, disease, and medication. In summary, the genetic influences on aging may be highly overrated, with lifestyle choices exerting far more important effects on physical aging.
