Whether tooth wobbling after root canal treatment can be self-healed depends on the evaluation of the condition of the tooth and periapical tissues, and it is usually impossible to self-heal for untreated or persistent chronic inflammation. 1. Condition of the tooth. Wobbling of the tooth after root canal treatment may be due to the apical periodontitis of the tooth itself causing a slight wobbling of the tooth, after root canal treatment, due to the elimination of inflammation, the looseness of the tooth will be slowly reduced or disappear, if the tooth is not well treated, the bacterial reproduction may cause acute apical periodontitis after the root canal treatment, and the looseness of the tooth will be increased. It is necessary to go to the hospital for treatment in time. 2. Periapical tissue condition. Tooth wobbling after root canal treatment is also related to the height of the alveolar bone and gingival attachment in the periapical region of the tooth. If the oral hygiene conditions are poor, the tooth attachment may cause progressive periodontitis damage, causing alveolar bone resorption, and the magnitude of tooth loosening will gradually increase. Whether tooth loosening after root canal treatment can be self-healing, the specific need to go to the hospital to check the oral cavity and X-rays and then combined with the medical history to determine.
