Dry mouth is a condition caused by the mouth being unable to produce enough saliva to keep the mouth wet. It can be caused by an underlying medical condition, certain medications and medical treatments, mouth breathing, tobacco use, and other factors. Saliva is needed not only to keep the mouth moist and comfortable, but it also contains antibodies that keep it clean and prevent infection. When the mouth cannot produce enough saliva, it causes a variety of complications that affect your oral health. Some symptoms of dry mouth may include an excessively dry feeling in the mouth or throat, a dry or irritated tongue, excessive thirst, sores in the mouth, bad breath and gum irritation. It may also cause issues with speaking or swallowing due to the excessive dryness if left untreated. Dry mouth can result in increased plaque and calculus buildup, which can cause tooth decay and gum disease. It can also cause irritation and inflammation of soft tissue because dry mouth can be caused by a variety of factors. It is important to discuss it with your doctor. There are multiple options for treating dry mouth issues that your doctor will explore with you based on your unique situation.
