While poor oral hygiene is the most prevalent cause of halitosis, many elements can contribute to or worsen the condition. One of these is the lack of saliva or xerostomia.
Saliva and Oral Health
Saliva moistens the teeth and gums and cleans away 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 shielding the gums from gingivitis. Saliva also functions as a disinfectant by cleansing the mouth of leftover food, bacteria, and fungi. This protects against cavities and infections.
Many men and women suffer from 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 sporadic periods of dry mouth, there is probably nothing to worry about. Constant dry mouth, however, can lead to additional oral and physical health issues.
