While inadequate oral hygiene is the most frequent cause of halitosis, many circumstances can contribute to or intensify the condition. One of these is the lack of saliva or xerostomia.
Saliva and Oral Health
Saliva moistens the teeth and gums and gets rid of odiferous dead cells. Saliva also neutralizes the ever-present acids on the tongue, gums, and cheeks and the minerals in saliva help to maintain enamel strength. Immunoproteins in saliva suppress the overgrowth of microbes in the mouth, thereby protecting the gums from gingivitis. Saliva also functions as a disinfectant by cleansing the mouth of leftover food, bacteria, and fungi. This safeguards against cavities and infections.
Many people experience dry mouth once in a while; perhaps when they are feeling anxiety or stress. Limiting caffeine, chewing sugar-free gum, using OTC saliva substitutes, and using a humidifier can add moisture to the mouth.
If you have infrequent periods of dry mouth, there is probably nothing to worry about. Constant dry mouth, however, can result in additional oral and physical health issues.
