Dry mouth occurs as the result of a decrease in the amount of saliva in your mouth. It may occur for several reasons, including: dehydration, as a side effect of medications, lifestyle habits like smoking, or a symptom of medical conditions such as the autoimmune disorder Sjögren’s syndrome.
What can cause it?
Many people commonly experience dry mouth because of dehydration and a lack of water throughout the day. Tea and coffee consumption may contribute as these drinks are diuretics, causing water to be eliminated from the body. For others, dry mouth occurs with the smoking, or the use of certain medications which are known to affect saliva flow and cause dry mouth. In fact, there are hundreds of medications known to have this as a side effect. Medical conditions such as Sjögren’s syndrome, which affects the salivary glands among other areas of the body, causes dry mouth in more frequent and severe ways.
The importance of saliva
Normal saliva production and flow is really important in helping to keep the teeth and mouth in a healthy state, it has several benefits and functions. Saliva helps to keep the mouth and soft tissues lubricated and moist, the ideal condition in the oral cavity. It neutralises acids that occur when we eat and drink, and helps to wash away food particles. A lack of, or absence of saliva, can negatively impact oral health. Dry mouth can lead to an uncomfortable or burning sensation on the tongue and soft tissues, increased rate and severity of dental caries (tooth decay), sores around the mouth, and bad breath.
