Gingivitis refers to a periodontal disease that does not have destructive capability. It is an inflammation that occurs on gum tissue. In most cases, this disease results from a reaction of the body towards bacterial infections. This happens when bacteria affects gum tissue making a biofilm known as plaque. The biofilm forms adjacent to the surface of the teeth. If left untreated, gingivitis will spread to periodontitis. This is a more destructive condition of this disease. However, there are cases when this disease does not progress to the periodontitis. An individual may live with gingivitis without ever progressing but it is still advisable to seek medication. Basically, there are two major categories of this disease. These are the dental plaque and the non-plaque gingivitis.
Dental plaque is the category of the induced gingival infections. These include sub categories of infections that have plaque association; those modified though medication and those resulting from systematic factors. There are also dental plaque diseases that results from malnutrition. Non-plaque category of gingivitis has eight sub categories. These include those of bacterial, viral, fungal and genetic origin. There are also infections that result from body reaction towards external infections, and also systematic conditions.
