Tooth movement, if there is no obvious trauma, is generally considered to be due to periodontal disease, which causes local resorption of the alveolar bone and leads to tooth loosening, which is the most common cause of tooth loosening and tooth loss in the oral cavity. This is the most common cause of tooth loosening and tooth loss in the oral cavity. Therefore, in case of tooth movement, you should come to the hospital for examination and treatment. If the degree of tooth loosening is not very serious, after the examination of the alveolar bone absorption within 1/3, you can also carry out local periodontal treatment or fixed loose teeth, can try to retain the teeth, if the tooth loosening is too obvious, the alveolar bone absorption is too much, there is no good treatment value, can only consider the extraction of such teeth.
