    How does COVID-19 affect salivary flow and xerostomia?

    Oct. 5, 2020
    Dr. Scott Froum looks at xerostomia and its causes. While there is much study to be done on the effect COVID-19 has on salivary flow, stress and anxiety can precipitate issues with dry mouth.

    The effects of COVID-19 on salivary flow and xerostomia (dry mouth) have yet to be fully studied. Typical causes of dry mouth can include mouth breathing, medications, autoimmune diseases, chemotherapy, nerve injury, and stress/anxiety. One study1 looked at the effect of stress, anxiety, and depression on unstimulated salivary flow, and it found a 40% drop in flow rates when compared to patients without these factors.

    COVID-19 has been a tremendous source of depression, anxiety, fear, and stress among the population as a whole. Combined with mouth breathing from mask use, COVID-19’s impact on dry mouth can be substantial. Having the ability to objectively diagnose dry mouth is important for the dental professional to provide the most effective treatment to the patient.

    In this video, Perio-Implant Advisory’s Editorial Director Scott Froum, DDS, demonstrates the BokaFlo salivary flow measuring device from Boka Sciences that is more accurate and expedient than traditional spit-cup flow measuring methods.
