If left untreated, periodontitis causes progressive bone loss around teeth, looseness of the teeth and eventual tooth loss.
Periodontitis is a very common disease affecting approximately 50% of U.S. adults over the age of 30 years.
GingivitisPeriodontitis is thought to occur in people who have preexisting gingivitis - an inflammation that is limited to the soft tissues surrounding the tooth and does not cause attachment or bone loss. The cause of gingivitis is the accumulation of a bacterial matrix at the gum line, called dental plaque. In some people, gingivitis progresses to periodontitis - the gum tissues separate from the tooth and, with loss of periodontal ligaments, form a periodontal pocket. Subgingival bacteria (those that exist under the gum line) that exist in periodontal pockets can cause further inflammation in the gum tissues and further loss of attachment and bone.
CalculusIf left undisturbed, bacterial plaque calcifies to form calculus. Calculus above and below the gum line must be removed completely by the dental hygienist or dentist to treat gingivitis and periodontitis. Although the primary cause of both gingivitis and periodontitis is the bacterial plaque that adheres to the tooth surface, there are many other modifying factors. One of the most predominant risk factors of periodontal disease is tobacco use. Another very strong risk factor is one's genetic susceptibility. Several conditions and diseases, including down syndrome, diabetes, and other diseases that affect one's resistance to infection also increase susceptibility to periodontitis.
