Every time you brush your teeth clean, you can use a special orthodontic toothbrush, interdental brush to clean up; 2, pay attention to the diet of large, hard, sticky food, all avoid eating. Large pieces of food or fruit as much as possible cut into small pieces to prevent damage to the aligner; 3, with the doctor to wear rubber bands in the orthodontic process, with good cooperation, can greatly shorten the orthodontic time; 4, regular review on time, fixed aligners with brackets, about four weeks to review once.
