Can a tooth grow back when it’s knocked loose?

Most of the teeth can grow back firm after being loosened, but a few of them may continue to be loosened due to periodontal disease, root fracture and alveolar bone fracture.
1. If the teeth are loosened due to trauma, after examination, only periodontal membrane damage, no alveolar bone fracture and root fracture, most of the teeth can be fixed, reduce occlusal trauma method can be long and firm, but need to be fixed together with multiple teeth.
2. The mobility of the teeth with periodontal disease, alveolar bone atrophy and resorption to the root of the tooth half the length of the possibility of restoration is not very large.
The restoration and fixation of the teeth is judged according to the specific location of the dislocated teeth and the age of the patient.
3. If it is a young permanent or milk teeth, just trauma-induced loosening, including embedded dislocation can not be restored to the normal position, generally let the teeth erupt on their own. Fixation is not necessary. However, if it is dislocated, it needs to be reset, fixed, and root canal treatment if necessary.
If there is any discomfort, go to the regular hospital stomatology department in time.
