Gag reflex is an involuntary defence mechanism to protect the pharynx and throat from foreign objects. Gagging is a common problem encountered during dental treatment, which makes therapeutic procedures distressing and often difficult or even impossible to perform. Various interventions can be used to control the gag reflex; for example, anti-nausea medicines, sedatives, local and general anaesthetics, herbal remedies, behavioural therapies, acupressure, acupuncture, and prosthetic devices.
