What is one common reaction in patients when dental impressions are taken?

One common reaction in patients when dental impressions are taken is the gag reflex. This reflex can be triggered during the impression process due to the material used or the positioning of the impression tray in the mouth. The gag reflex is a protective mechanism that aims to prevent choking or aspiration by forcing the patient to expel foreign objects or irritants. Many patients experience this reflex, especially if they have a sensitive gag reflex or a strong aversion to objects placed in the back of their mouth. Understanding this reaction is crucial for dental professionals, as they can take steps to minimize discomfort and anxiety associated with the procedure, such as using distraction techniques, ensuring proper tray positioning, and selecting appropriate impression materials. This awareness helps ensure a more comfortable experience for the patient during dental appointments.
