Whether you can do braces after one year after root canal treatment is mainly related to the defective and split teeth, if the teeth are in good condition, then you can do braces after one year, but if the teeth are not in good condition, then you can’t do braces after one year. 1. Can do braces after one year: If there is no obvious defect and no splitting of teeth after root canal treatment, then braces can be done after one year. Pay attention to oral hygiene and try not to chew food on the affected side of the tooth. 2. Can’t do braces after one year: If the problem of chipped or cracked teeth is more serious, you may need to install braces immediately to avoid affecting the effect of root canal treatment. Because the tooth will become more fragile and easy to break after root canal treatment, it is necessary to install braces in time to protect the tooth. It is recommended to choose the follow-up treatment after root canal treatment as prescribed by the doctor and to have crown restoration in time. If there is any abnormality, you should go to the dentistry department of the regular hospital in time to deal with it.
