Childhood obesity is a significant health problem on a national and international scale. Over the last few years, the prevalence of obesity in children has surged. It is caused by a discrepancy between calorie intake and calorie expenditure. Obesity in children is caused by one or more factors that can be genetic, behavioural, or environmental. Childhood obesity can cause physical, psychological, and social health problems. Obesity is difficult to reverse once established and is linked to worse health outcomes in the short and long run. Hence, managing obesity in childhood is critical for lowering long-term risks and protecting health. This manuscript aims to discuss the various factors that influence childhood obesity, the various interventions and actions that address obesity, and the challenges that lie ahead in managing this epidemic. The document also highlights the correlation that exists between childhood obesity to common dental problems like dental caries and malocclusion.
