Loose or fractured dentures may be displaced towards the back of the mouth into the pharynx and become ingested or inhaled. The consequences of denture impaction on a patient's health can be severe, both short-term and long-term. Diagnosis and treatment can be challenging, therefore an understanding of the incidence, risk factors, symptoms and management of risk factors is important to reduce the occurrence of denture impaction in the aero-digestive system. This article includes an overview of the related literature and highlights the importance of managing risks and the importance of good denture design and appropriate maintenance.
Clinical Relevance: Dentists need to be aware of risk factors and harmful effects associated with inhaled and swallowed dentures to help minimize the incidence.
Article
Cases where various types of dental objects, including dental bridges and an orthodontic band, have been swallowed have been described by Al-Wahadni et al.1 Loose or fractured dentures may also be displaced towards the back of the oral cavity into the pharynx and become ingested or inhaled. Denture impaction in the gastrointestinal or respiratory tract is uncommon, however, the consequences of denture impaction on a patient's health can be severe both short-term and long-term.
This article describes the incidence, harmful effects and risk factors associated with denture impaction in the aero-digestive system. Preventive measures that should help to reduce the risk of inhalation and ingestion are also discussed.
In order to obtain information on incidence and harmful effects, an electronic search was performed on Google Scholar and PubMed databases using the search terms ‘swallowed denture’ and ‘inhaled denture’. The search yielded 184 relevant articles. References from the articles were not used to extend the search. Of the 184 articles, 16 were case series, 160 were case reports, 3 were review articles and 5 were biomaterials research related to radio-opaque denture base materials.
