Some orthodontic patients believe that teeth should not be extracted during orthodontic treatment, and that extraction at this time will hurt the bones and lead to loosening of the entire mouth and decrease in oral function, which will eventually damage the health of the whole body. Is this really true? In fact, modern orthodontics has experienced more than a century of technical development and clinical practice, fully verified the feasibility of tooth extraction in orthodontics and its important role in improving the effectiveness of orthodontics, orthodontic clinicians have used tooth extraction as a routine means to treat some patients with serious dental malocclusion. In some cases of anterior protrusion and crowded teeth, the extraction gap was used to retract the protruding front teeth to improve the patient’s dental alignment and facial appearance. The reestablishment of tooth alignment and occlusion in orthodontic patients after treatment will only be more beneficial to their orofacial system. A number of clinical problems caused by tooth extraction are often the result of improper orthodontic design and treatment errors. The relative lag in the registration and certification of domestic orthodontic specialists has resulted in a large number of general dentists also getting involved in the field of orthodontics. Due to the lack of proper extraction criteria and professional orthodontic skills, these amateurs often arbitrarily remove patients’ teeth and recklessly close the extraction gap, resulting in poorer alignment and occlusion of the posterior teeth at the end of treatment, which is even worse to witness. Who can be happy if the patient spends money and time and gets such treatment consequences? Therefore, tooth extraction itself is not the problem, but amateurish and indiscriminate treatment should be more worrying for patients and families.
