Gum disease resulting in inflammation of the gums that can progress and reach the bone that surrounds and supports teeth. They are the consequence of the action of bacteria in dental plaque, a sticky coating, colorless, which settles permanently on the teeth. If not removed by brushing and floss, plaque and bacteria grows not only infect the gums and teeth, but the bone that supports teeth. Eventually, it may shoes teeth and to bring down or force them to extract.
Gum disease through three stages:
* Gingivitis: This is the initial stage of the disease, an inflammation of the gums caused by plaque at the gingival border. If the brushing and cleaning floss can not remove plaque, toxins (poisons) that it produces will irritate the gum tissue and cause gingivitis. One can observe the bleeding when brushing and cleaning floss. This gingivitis is reversible, bone and connective tissue supporting the teeth are not yet achieved. 
* Periodontitis: The bones and fibers that hold teeth in place are irreversibly damaged. Pockets begin to form between the tooth and gum; these pockets trap food and plaque. Appropriate treatment and better personal dental hygiene are usually sufficient to halt the spread of the disease.
* Advanced Periodontitis: The disease has progressed, fibers and bone surrounding the teeth are destroyed, which can lead to migration (travel) and mobility. The way you bite can be modified and whether the treatment can save set teeth, they should be extracted.
