Disease the stages of periodontal disease

The stages of Periodontal Disease
Gingivitis
1. The dental plaque produced toxins that irritate the gum tissue. Gingivitis is the inflammation of the gums characterized by redness, swelling, and sometimes bleeding during brushing.
2. The gums start receding and bleeding, loosening their attachment to the tooth and exposing previously covered enamel or part of the tooth root.
At this early stage of gum disease, damage can be reversed with proper dental hygiene, since the teeth are still firmly planted in their sockets without any bone or connective tissue damage.

Periodontitis
3. Plaque bacteria start to penetrate between the teeth and gums. The environment becomes suitable for the establishment of anaerobic bacteria under the receding gums. Gingival pockets are formed below the gumline.
4. The surrounding connective tissues and alveolar bone become infected. Bacterial toxins and the body's enzymes fighting the infection start to break down the bone and connective tissue that hold teeth in place.
At this stage, the supporting bone and fibers that hold the teeth in place are irreversibly damaged. Proper dental treatment and improved dental hygiene can usually help prevent further damage.

Advance Periodontitis
5. As the periodontal disease progresses, the pockets deepen and more gum tissue and alveolar bone are destroyed. Ultimately all the supporting structures of the tooth may be lost.
6. The tooth gradually loosens and, if periodontitis is left untreated, the tooth will eventually be lost (fall out or have to be removed a dentist).
