Many patients have the concern that orthodontics can cause premature tooth loss? Patients who are suitable for orthodontics will not have the possibility of premature tooth loss. First, uneven teeth are not easy to clean, so such patients are more likely to suffer from periodontal disease, which often leads to the resorption of the alveolar bone, leading to the loose loss of teeth in severe cases. Secondly, the force of orthodontic treatment is minimal and does not lead to the resorption of the alveolar bone and the resorption of the tooth roots, and the interval between each follow-up visit is usually 4-8 weeks, giving the alveolar bone sufficient time to grow. There will be mild loosening of the teeth during the orthodontic treatment, but after a certain period of time to maintain the teeth after the orthodontic treatment, the loosened teeth become strong again. Third, orthodontic treatment aligns the teeth and reduces the chance of plaque attaching to the teeth. At the same time, a normal bite is established and the periodontal tissues of the teeth are healthier, which not only improves chewing efficiency but also reduces the incidence of dental diseases and effectively prevents the loosening and loss of teeth when people grow old. However, not everyone is suitable for orthodontic treatment, we must first determine the health of the patient’s teeth, only relatively healthy teeth and periodontal tissues are also relatively healthy premise for orthodontic treatment. Therefore, patients need to undergo a comprehensive oral examination under the guidance of an orthodontic specialist in order to make orthodontic treatment more successful and to have healthy and beautiful teeth for life.
