Periodontal examinations and full-mouth surface tomography are required for loose teeth during cosmetic dentistry. If there is a lot of food debris and soft scale attached around the labial brackets and ligature wires of the teeth and mineralized as calculus, ultrasonic scaling is required to remove the calculus and periodontal rinsing with hydrogen peroxide solution is performed. Patients are instructed to enhance oral hygiene cleaning by using dental floss, flushers, interdental brushes and other auxiliary cleaning tools, together with the use of chlorhexidine and other rinses. If the edge of the band ring of the supporting anti-abrasion teeth is too long and stimulates gingival redness and recession, the edge needs to be trimmed and polished. If the orthodontic force is too high and causes the teeth to tilt, move or loosen, it is necessary to switch to a finer archwire to reduce the orthodontic force.
