What Is Dry Mouth?

Dry mouth, also called xerostomia, is a persistent feeling that there is not enough saliva in your mouth. Depending on how severe your condition has become, it may cause a variety of symptoms such as a sticky or dry mouth, or you may find it difficult to swallow food.1

Whatever your symptoms are, it’s important to know that you shouldn’t ignore dry mouth. If you have a feeling of mouth dryness, it means that something has caused a reduction of saliva. Saliva is essential for keeping your mouth lubricated and healthy. It cleanses your mouth, helps you swallow and talk, and aids digestion and taste.2
