A concerning increasing trend of severe dental neglect or "dental neglect" has been discovered in Japan with observations reaching as high as 20 decayed teeth in some instances. The situation underscores the urgent need for public health interventions and better awareness about dental health, particularly among parents and guardians. The issue is not just a health concern but also has socio-economic implications for the country.

Though oral hygiene is generally given importance in Japan, the issue of severe dental neglect, especially among children, has been a growing concern. Dental health is tied to overall health, and negligence can have broad implications that affect school attendance and self-esteem. The issue highlights the need for better health education and access to affordable dental healthcare.

In the US or EU, dental care is a significant part of children's public health services. Regular dental check-ups from a young age are commonly practiced, and there are public health campaigns regarding good oral hygiene habits. The necessity of dental care is widely recognized, and neglect cases could potentially trigger child welfare services, dependent on the severity of neglect.
