Dry Mouth and Its Connection to Bad Breath

When you first wake up, you may notice a bad odor to your breath. This is because the mouth is particularly dry first thing in the morning. Teachers and others who speak a great deal may also notice that after speaking, their mouths are particularly dry. Sometimes you may become dehydrated from lack of fluid intake, and develop a dry mouth.

Saliva is the natural fluid produced by the mouth to cleanse, lubricate, moisturize, and break down food. Saliva is produced from water we drink, so it is very important to have a proper intake of fluids. However, saliva is not just water. It also contains enzymes that break down starches, and other components that help to kill bacteria in the mouth.

Some dry mouths are more severe than others. A chronic dry mouth condition, called “Xerostomia,” may stem from medications or disease. Antihistamines, diuretics, and anti-anxiety medications are common causes of Xerostomia, although other drugs may also cause this condition. Age may also be a factor in developing Xerostomia.

The link between bad breath and dry mouth is fairly simple. Whether the dry mouth is caused by open-mouthed breathing or disease, saliva dries up and cannot coat the teeth, mouth, and gums. This prevents the removal of food and other debris upon which bacteria feed. The bacteria quickly multiply, causing bad breath. Further, dry mouth and lack of saliva is a factor in developing gingivitis, or gum disease, which also contributes to bad breath.
