Gagging is a normal protective reflex to prevent foreign bodies entering the trachea. Some individuals are more prone towards gagging. Gagging in dental patients can be disruptive to dental treatment and may be a barrier to patient care, preventing the provision of treatment and the wearing of prostheses. Various local and systemic factors such as alcoholism, gastrointestinal reflux and foreign bodies irritating soft palate or choking the oropharyngeal region can trigger this reflex. A complete oral examination, medical history, and conversation with the patient are important sources of information that assist with the management of gagging problems. Many techniques are available for controlling the exaggerated gag reflex, and no single technique will solve each patient's problem. The article discusses various techniques to prevent gagging during dental treatment.
