Common tooth problems in children include cavities, which are caused by sugary diets and inadequate oral hygiene; gum disease, often stemming from plaque buildup; and misalignment of teeth, known as malocclusion, which may require orthodontic intervention. Additionally, children can experience tooth sensitivity, especially when consuming hot or cold foods, as well as issues with their primary teeth, such as early loss or decay. Tooth grinding, or bruxism, is also common and can lead to wear and discomfort. Regular dental check-ups are essential for early detection and prevention of these issues.
