Continued bad breath in your mouth may be a warning sign of gum (periodontal) disease. Gum disease is caused when there is a buildup of plaque on the teeth. The bacteria present in the mouth cause the formation of toxins which lead to irritation in gums. Gum disease is a known cause of bad breath as the gums pull away from the teeth and leave behind pockets in which bacteria settles and replicates, which also causes halitosis (bad breath).
Periodontitis is the inflammation of gums and supporting structures of the teeth. It is one of the most common dental diseases. Periodontitis is caused by certain bacteria (called periodontal bacteria) and by the local inflammation caused by the action of those bacteria.
Stage 1 is early Gum Disease/Gingivitis which is characterised by the gums turning pink and there's going to be little to no signs of bleeding or inflammation. Stage 2 is mild periodontitis and stage 3 represents advanced periodontitis. As the bacteria and plaque are left to grow and the disease progresses, the gums and teeth start to separate further from each other. This leads to the development of deep gingival pockets, which can promote bacterial growth. This leads to mild and then advanced stages.
The image shows healthy teeth vs teeth with periodontal disease. Swollen and bleeding gums are early signs of periodontal gum disease. Gingivitis (gum inflammation) generally precedes periodontitis (gum disease). However, not all gingivitis progresses to periodontitis.
Periodontitis is a inflammatory diseases affecting the periodontium, the tissues that surround and support the teeth. It is a serious gum infection that damages the soft tissue and the bone that supports your teeth. The condition can cause your teeth to loosen or lead to tooth loss. Periodontitis is a quite common dental problem but is largely preventable.
