The basic problem in dry mouth, or xerostomia, is a lack of saliva. This can be caused by diseases of the salivary gland, medications that decrease salivary flow as a side effect or as a natural result of aging. This decrease in saliva can lead to a number of severe dental problems such as gum disease, tooth decay and mouth infections.
The best way to combat this problem is to use sugar free candy or gum and to drink plenty of water. Do not use sugared candy or soda, as they can lead to rapid dental decay in patients with dry mouths. Several over the counter products are also available that can help with some dry mouth symptoms. If you’re concerned that you may have xerostomia, contact your dentist or physician to determine its cause and see what might work best in your situation.
