1. Improvement of children's oral health awareness: In recent years, with people's attention to health and quality of life, more and more parents began to pay attention to children's oral health problems. The development of children's dentistry just caters to this demand.

2. High incidence of children's oral diseases: In modern life, children's oral health problems have become increasingly prominent due to poor eating habits and lack of oral hygiene. For example, dental caries, tooth deformity and periodontal disease often accompany the whole childhood and need professional treatment and attention. Pediatric dentistry has become a necessary development direction.

3. Lack of children dentists: Because of the particularity and complexity of children's oral health problems, they need to have professional skills and knowledge like adult dentists. However, in many countries and regions, the number of children's dentists is relatively small, and the market demand is large. The shortage of talents has become one of the reasons to promote the development of children's dentistry.
