Whether a loosened incisor will grow in automatically needs to be judged according to the cause of the loosening. 1. If the loosening of the incisors is not serious, and there is a slight jaw trauma, the roots of the teeth are generally not broken and may gradually tighten after fixation, which basically will not have a greater impact on the individual’s body. 2. Some patients may also have loose incisors after periodontitis, etc., which may be improved after periodontal treatment, but it is difficult to restore the loose teeth after attachment loss. 3. If the impact is more serious, there is obvious fracture, this situation may not be able to grow tight, if necessary, it may be necessary to remove the teeth in time. Usually, you need to avoid trauma, and also need to see your doctor regularly for dental checkups.
