Gingivitis usually refers to gum inflammation while periodontitis refers to gum disease and the destruction of tissue and/or bone. Initially, with gingivitis, bacteria plaque accumulates on the surface of the tooth, causing the gums to go red and inflamed; teeth may bleed when brushing them.
1 Without enough saliva, the mouth is vulnerable to infections such as gum disease. 2  And some medicines can cause abnormal overgrowth of the gum tissue; this can make it difficult to keep teeth and gums clean. 3  Genetic susceptibility. 4  Some people are more prone to severe gum disease than others.
