While poor oral hygiene is the most common cause of halitosis, many conditions can contribute to or exacerbate the condition. One of these, the team at Mt. Vernon Center for Dentistry in Alexandria VA explains, is the lack of saliva or xerostomia.
Saliva and Oral Health
Saliva moistens the teeth and gums and removes 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 durability. Immunoproteins in saliva curb the overgrowth of microbes in the mouth, thereby safeguarding the gums from gingivitis. Saliva also functions as a disinfectant by cleansing the mouth of leftover food, bacteria, and fungi. This guards against cavities and infections.
Many men and women are plagued with dry mouth sporadically, like when they experience 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 occasional periods of dry mouth, there is probably nothing to worry about. Constant dry mouth, however, can cause additional oral and physical health troubles.
