If your teeth show symptoms such as red and painful gums, bleeding from brushing, loose and shifted teeth, teeth appearing longer, tooth loss, bad breath, weakness in chewing, and larger gaps between teeth, it means you have periodontal disease! Periodontal diseases are diseases that occur in the supporting tissues (periodontal tissues) of the teeth, including gum disease that involves only the gum tissues and periodontitis that affects the deep periodontal tissues (periodontal membrane, alveolar bone, dental bone). Periodontal disease is a common oral disease, one of the main causes of tooth loss in adults, and the main oral disease that endangers human dental and systemic health. Gingivitis The main symptoms of gingivitis are confined to the gum tissue, and redness, swelling, vague pain and bleeding from brushing the gums are common symptoms. Periodontitis In addition to the symptoms of gingivitis mentioned above, periodontitis can also invade the alveolar bone and periodontal ligament below the gums. Once periodontitis has progressed, the alveolar bone and periodontal ligament are damaged, and naturally the teeth begin to loosen and become sore and weak when biting. The gums and teeth are stripped and pockets are formed, and the tiny food residue from eating is easily retained in the periodontal band, which is used by bacteria to ferment and spill out bad breath, and in severe cases, abscesses and fever can occur.
