A review of gagging problems in dentistry: aetiology and classification.

Some people have a pronounced gag reflex that can be a severe limitation to their ability to accept dental care and the clinician's ability to provide it. It can compromise all aspects of dentistry, from diagnostic procedures to active treatment and can be distressing for all concerned. Many techniques have been described that attempt to overcome the problem. Dentists will undoubtedly see patients with gagging problems and knowledge of a variety of management strategies is necessary to aid the delivery of dental care. This first paper looks at the background to gagging problems and their classification and categorization prior to clinical treatment. The second article will look at the clinical assessment of the patient presenting for dental treatment with a history of gagging problems. It will also review methods used to manage patients with gagging reflexes during dental treatment.
