Loose incisors should be treated with periodontal therapy, root canal therapy, and immobilization depending on the specific cause of looseness. 1. The most common cause of loosening is periodontitis, which is caused by alveolar bone resorption. If you want to stop the alveolar bone resorption, you should take periodontal treatment to control the inflammation. 2. If the tooth loosening is caused by acute apical periodontitis or acute attack of chronic apical periodontitis, root canal treatment should be carried out. 3. After the periodontal inflammation is controlled, or if the loosening is caused by certain trauma, bonding and splinting can be used. Loose incisors are recommended to go to the hospital in a timely manner, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
