Periodontal disease is unlikely to be cured in one go because periodontal disease is a chronic progressive disease, just like hypertension or diabetes, and there is no such thing as a complete cure. Even if you have had systematic periodontal treatment and show significant improvement, you still need to pay attention to it from time to time in the future. In addition to regular daily brushing and exercise, you need to visit the dentist regularly every year to see if the periodontal disease has recurred and progressed. So except for bleeding caused by gingivitis, it is possible that bleeding from gingivitis will no longer occur with a single periodontal treatment. Many of all the remaining diseases involved in periodontitis are irreversible, and once gum recession, alveolar bone resorption, and tooth loosening occur, a series of treatment operations are required to try to slow or stop the progression of this series of diseases.
