Abstract: In recent years，people′s demand for orthodontic treatment has grown by leaps and bounds. At this stage，orthodontic patients often suffer from dental diseases such as enamel demineralisation and caries. These diseases not only affect the aesthetics of the teeth and reduce patients′ satisfaction with orthodontic treatment，but may also develop into serious endodontic diseases if they are not treated promptly and appropriately. It is of great significance in orthodontic treatment to be familiar with common dental diseases and to master the treatment timing and methods. In this paper，we summarise the common dental diseases and their causes in orthodontic treatment and review the research progress in its treatment strategies，with the aim of providing a reference for orthodontic treatment.

Key words: orthodontic treatment, dental restoration, dental damage
