Braces usually allow normal chewing after three to five days.
1. Braces is a treatment used for orthodontics, the specific method is to use brackets to fix the orthodontic archwire on the teeth, and use the orthodontic force generated by the archwire to rearrange the teeth; the whole orthodontic process takes about two to three years.
2. The principle of orthodontic treatment is to utilize the plasticity of the alveolar bone, i.e., the alveolar bone will be absorbed and remodeled when it is subjected to the force, which will make the teeth move; therefore, when the braces are just put on, there will be the symptom that the teeth are too sore and soft to be able to chew due to the remodeling of the alveolar bone, and a liquid diet is needed; however, the symptom can be relieved in three to five days, and a semi-liquid diet can be taken and normal chewing can even be resumed.
