In general, orthodontics is harmless. However, if the patient does not choose a regular hospital, the correction may fail and cause harm to the patient.

1, adverse effects on root: This is a common harm in orthodontics, because the tooth root appearance is undergoing reconstruction activities such as absorption and proliferation during orthodontics. After treatment, the roots recover normally with their own repair ability, but if the therapeutic force is too great, the harm of tooth extraction will be aggravated.

2, the teeth become loose, the teeth should move: it is necessary to rebuild the alveolar bone and periodontal ligament, because the teeth are firmly fixed in the alveolar bone by periodontal ligament, so the teeth will become loose. However, after the teeth are corrected to the normal position and stop moving, the teeth may be able to reattach the periodontal ligament through their own repair ability and become stable without causing permanent damage.

3. Adverse effects on dental pulp: At the initial stage of orthodontic treatment, there is a mild and temporary inflammatory reaction in dental pulp, which shows that patients in our hospital have pain, sadness or discomfort in the first few days after stress, but practice has proved that the harm of orthodontic treatment has no clinical significance. After the above description of the harm of orthodontics, it can help people to establish an accurate understanding of orthodontic methods. At the same time, the harm of orthodontics also reports that people should choose the nearest hospital for regular orthodontic treatment, so as to ensure the effect.

4. Adverse effect on alveolar bone height: it is a potential hazard of orthodontics. People who have done orthodontics have a small amount of depression in the height of alveolar bone. This is because wearing orthodontic appliances, oral hygiene is difficult to connect, which increases the probability of gingivitis and has a certain adverse effect on alveolar bone. After orthodontic treatment, alveolar bone will not be absorbed continuously. If it is associated with oral hygiene, alveolar bone will gradually return to normal.
