Aligner therapy is an easy way to straighten teeth without brackets and wires. Images, photos, and x-rays are taken to create a 3D model of the mouth, and then a series of clear plastic aligners are created. The removable aligners are replaced periodically, with each set targeting specific tooth movement. Many cases of crowding, spacing, and misalignment can be treated with this type of Orthodontic program, recognized by names like Invisalign and Clear Correct.
