Frequent loosening of teeth can be caused by a variety of reasons, and the exact treatment depends on what is causing the problem. Some of the common causes are periodontitis, poor bite condition, and acute inflammation. Specific descriptions are as follows: 1. Periodontitis can lead to chronic progressive tooth loosening. 2. Poor occlusal condition of the teeth, causing trauma to the teeth and thus causing loosening of the teeth. 3. Sudden biting of hard objects, trauma, etc. can also cause loose teeth. 4. Acute inflammation and edema of the periodontal tissues can cause painful biting of the teeth or painful gums, which can cause loose teeth in the long run. Teeth loosening caused by periodontitis should be consulted as early as possible, and dental scaling and subgingival scraping should be performed to remove tartar, plaque and other inflammation-causing things around the teeth, and to reduce the inflammation around the teeth. Tooth loosening caused by occlusal conditions should be diagnosed by an oral surgeon. Therefore, the specific treatment must be done after the doctor’s examination to determine the cause of the disease and then do the treatment for the cause, not blindly use drugs to treat.
