Gingivitis simply means inflammation of the gums. The direct cause is plaque which builds up on your teeth due to improper brushing after meals. Plaque can be described as a soft, sticky, colourless film of bacteria that forms on the teeth and gums through a combination of several strains of bacteria, leftover food and saliva.
Gingivitis is a non-destructive type of periodontal condition, however, if the plaque is not removed by daily brushing and flossing, it produces toxins that can not only irritate the gum tissue but also the supporting bone which can cause periodontitis. This condition is more serious periodontal condition and can eventually lead to loss of teeth (1).
