It is mostly not possible to do braces one year after root canal treatment, usually braces are done 1~3 months after root canal treatment, and good dental care is needed after root canal treatment. Teeth undergoing root canal treatment are prone to chipping due to the lack of blood vessels and nerve nutritional support, and braces need to be done in a timely manner to protect the tooth. If braces are made a year after root canal treatment, the chances of the tooth chipping are higher. Under normal circumstances, the time to do braces after root canal treatment is 1~3 months, which needs to be determined according to the recovery of each patient’s tooth. It is recommended to avoid eating too hard and sticky food during the period when the tooth has not been braced after root canal treatment, usually do a good job of cleaning the teeth, choose a soft-bristled brush, and don’t be too strong when brushing the teeth. It is recommended that the time to do braces after root canal treatment should be decided by the dentist, and the patient should cooperate with the doctor.
