There is no such thing as the best remedy for loose teeth, and remedial measures need to be targeted depending on the cause of the loose tooth. Common causes of loose teeth include external impact, periodontitis, and apical periodontitis. 1. Impact: When a tooth is impacted by an external force, it can be fixed with a loose tooth if it can be considered for retention after evaluation. If the root of the tooth is fractured and damaged due to impact, and the tooth cannot be retained after evaluation, extraction of the affected tooth can be considered. 2. Periodontitis: If the patient has more tartar in the mouth, red and swollen gums, and loose teeth, it may be periodontitis. In this case, periodontitis needs to be treated systematically in order to alleviate the looseness of the teeth, which should be done according to the doctor’s recommendation. 3. Apical periodontitis: Inflammation and oozing from the root tip of the tooth cause the tooth to loosen obviously, patients with apical periodontitis can also be relieved of the looseness of the tooth after drainage and root canal treatment to reduce inflammation. If the tooth is loose, it is still necessary to go to the hospital for examination, to clarify the cause of the disease and diagnosis, and under the advice of the doctor for treatment.
