Head and neck area infections in children can be severe, necessitating an immediate diagnosis and course of treatment. These infections are frequently brought on by periapical abscesses, dental trauma, untreated dental caries (cavities), or consequences from dental operations. Poor oral hygiene practices and postponed dental treatment in children might raise the risk. Swelling, discomfort, fever, trouble swallowing, trismus (inability to open the mouth), and occasionally difficulty breathing or speaking are common symptoms in children with head and neck region infections. Clinical examination, patient history, and imaging tests like dental radiographs (X-rays) and CT scans to map out the extent and location of the infection are commonly used by paediatric dentists and healthcare professionals to identify these illnesses. To manage the illness, broad-spectrum antibiotics are frequently administered. These infections, if ignored, can result in potentially fatal consequences such as cellulitis, Ludwig's angina, mediastinitis, and sepsis.
