Whether or not to wear braces after filling is divided into different situations: 1, if the tooth defect is on the occlusal surface, because its retention and adhesion are strong, the material is less likely to fall off, so you can not wear braces; 2, if the tooth defect is between two adjacent teeth, or a large area of teeth with filling material, because it is easy to fall off, it is recommended that patients wear braces; 3, if the tooth is easy to break or has had root canal treatment, it is recommended that patients wear braces; therefore, patients have to decide whether or not to wear braces according to the specific situation and according to the doctor’s advice.
