- Dry mouth occurs when salivary glands produce insufficient saliva.
- It can cause cavities, gum disease, and digestive discomfort.
- Common causes include medications, dehydration, and systemic diseases.
- Relief methods include hydration, sugar-free gum, and humidifiers.
- Regular dental checkups prevent complications from chronic dry mouth.
Dry mouth, or xerostomia, is a common issue that occurs when the mouth fails to produce enough saliva. This can negatively affect oral functions and make digestion more difficult. If left untreated, it may lead to cavities, gum disease, and tooth sensitivity. If the cause of dry mouth is not related to lifestyle habits, underlying medical conditions should be investigated. Addressing the root cause allows for more effective treatment and resolution of dry mouth symptoms.
What Is Dry Mouth?
Dry mouth occurs when the salivary glands do not produce enough saliva. Saliva plays a critical role in oral health—it helps digestion, protects the teeth from decay, and keeps the oral tissues moist to prevent infections.
Dry mouth may be temporary or a sign of an underlying medical condition. It must be treated as it can impair oral functions and negatively impact daily life. Prolonged dry mouth can lead to tooth decay and gum disease.
Which Medical Specialty Treats Dry Mouth?
The appropriate specialist depends on the underlying cause. Although dentists are often the first point of contact, if the cause is systemic, specialists such as ENT, internal medicine, or endocrinology may need to be consulted.
What Are the Symptoms of Dry Mouth?
