Please tell me the precautions during orthodontic treatment.

During orthodontic treatment, 1) avoid tough, hard foods such as dried squid, ice, and hard candy (the main cause of brackets coming off), and 2) brush more carefully than usual after meals and before bed, using an interdental brush as well, since cavities form easily around the appliance. 3) Keep your appointments every 4 to 6 weeks so the treatment does not drag on. If a bracket comes off or a wire is poking you, do not wait - call the clinic right away.
