If only one tooth is a little crooked, it is not necessary to wear full braces when correcting. Generally speaking, for the correction of a tooth, the doctor will apply force to the deformed tooth with a local appliance or bracket to gradually move it to the correct position.

Specifically, if only one tooth is deformed, the doctor may use a single bracket or local appliance to correct this tooth. Single braces usually include brackets made of metal or ceramic materials, which need to be fixed on deformed teeth, and then arch wires are inserted into the brackets to exert force, so that the teeth gradually move to the correct position.

In addition, if there are healthy teeth before and after the deformed teeth, doctors may use a technique called "adjacent enamel removal" to correct the deformed teeth. This technique needs to remove a small part of the surface of the front and rear teeth, and then make a special appliance on the surface of the teeth, and gradually move the deformed teeth to the correct position by applying force.

In short, you don't need to wear a full mouth of braces for the correction of a tooth. However, in the process of correction, it is necessary to ensure the health and hygiene of the whole oral cavity and avoid other oral problems. At the same time, it is suggested that corrective treatment should be carried out under the guidance of doctors to ensure the therapeutic effect and the safety of patients.
