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.
