Mouth breathing is a frequent functional disorder in children and adolescents and is commonly associated with upper-airway obstruction, altered orofacial muscle balance, and abnormal dentofacial growth. Although the topic is usually discussed in pedodon- tics, orthodontics, and otolaryngology, its long-term consequences are also relevant to prosthodontics, because untreated cases may reach adulthood with constricted arches, an altered vertical facial pattern, malocclusion, oral dryness, and functional instability that complicate rehabilitation. Contemporary meta-analyses confirm that mouth breathers differ from nasal breathers in measurable craniofacial parameters, including reduced SNA and SNB angles and increased vertical facial dimensions. At the same time, digital dentistry has improved the documentation and planning of such patients through intraoral scanning, selective cone-beam computed tomography (CBCT), CAD/CAM workflows, and three-dimensional data integration. This narrative review presents a concise in- terdisciplinary overview of the causes of mouth breathing, the craniofacial and prosthodontic implications of persistent childhood cases, and the role of digital dentistry—including emerging artificial-intelligence and additive-manufacturing applications—in diag- nosis and treatment planning.
