What causes Periodontitis?

The main cause of periodontitis is dental plaque: a thin, slimy colourless layer on the tooth. If this dental, or otherwise microbial plaque is not removed, it develops into a hard uneven surface, known to all as- "dental calculus" - Calculus plays host to many micro-organisms which constantly create toxins. The toxins irritate the gingiva and in time destroy it. The gingiva becomes softer and is detached from the tooth and the gingiva, and this results in large fissures between the teeth and the gingiva, known as pockets. In their turn the sockets are filled with plaque and a vicious circle is created by which the disease develops continuously and the gingiva is destroyed, the sockets become deeper and deeper and the dental plaque moves deeper down along the root surfaces. The bone which supports the tooth, is destroyed and is then reabsorbed leaving the root exposed. The tooth then becomes more and more mobile, leading to the total destruction of periodontium and the eventual loss of the tooth.
