Periodontal disease or periodontitis is a chronic infection of the gingiva, meaning that it has been sick a long time. It is slow in evolution and destroys the tissues that support the teeth. It’s caused by the accumulation of dentobacterial plaque. If this plaque is not removed properly with the tooth brush and floss, it begins to build up tartar. This stage is called gingivitis and is characterized by the inflammation and bleeding of the gingiva. Its treatment is relatively simple and with a visit to the periodontist its progress can be stopped.
