When a patient suffers from periodontitis, it means that the periodontal tissues are in an inflammatory phase. The inflamed gum tissue may exhibit symptoms such as redness, pain, and a relatively soft texture. Touching it may cause bleeding. Some patients may experience pus discharge and loosening of teeth, which are common symptoms of periodontitis. As the condition progresses, the spaces between teeth may increase, eventually leading to shrinkage of the gum tissue, loosening of teeth, or even tooth loss. Therefore, it is recommended that patients with periodontitis seek timely medical attention at a reputable dental hospital and take appropriate measures. Additionally, it is essential for patients to maintain correct tooth brushing methods and develop proper oral hygiene habits in their daily lives.
