Periodontitis starts as inflammation with bleeding from the gums and deep gum pockets. If the inflammation is not stopped, it spreads to the bone that holds the teeth, which will recede, and eventually, the teeth will become loose and fall out.
The treatment of periodontitis aims to stop the bone's deterioration and remove the inflammation. This is done through thorough and extended dental cleaning and root cleaning of the deep gum pockets. In periodontitis, the gum pockets become deep, making it difficult/impossible to clean effectively around the teeth.
