Does your mouth feel uncomfortably dry sometimes, even when you aren’t thirsty? Do you find yourself drinking water frequently just to stimulate saliva flow? If so, you may be experiencing dry mouth (xerostomia), a common condition that results from lowered saliva production. Saliva plays a key role in oral health by keeping the mouth moist, washing away food debris, and helping prevent issues like tooth decay, gum disease, and mouth sores. A persistent lack of saliva due to a dry mouth can lead to several oral health problems if left unmanaged. This blog aims to help readers understand dry mouth and identify simple steps to prevent oral health issues through proper hydration and salivary gland support.
Causes of Dry Mouth
There are many potential causes of dry mouth, from medications to medical conditions. The most common culprits include:
Prescription Drugs: Over 500 prescription and over-the-counter medications list dry mouth as a side effect, including antihistamines, decongestants, antihypertensives, antidepressants, Parkinson’s drugs, and pain relievers.
Radiation Therapy: Cancer treatment of the head and neck region damages salivary glands and often leads to long-term dry mouth.
Autoimmune Diseases: Sjögren’s syndrome is an autoimmune disorder directly targeting the salivary and tear glands.
Diabetes: High blood sugar levels from uncontrolled diabetes can impact moisture production in the mouth.
Dehydration: Not drinking enough fluids is an obvious yet easy-to-miss cause of dry mouth in everyday life.
Breathing through the mouth: Habitual mouth breathing can cause saliva evaporation and dehydration of oral tissues.
Anyone experiencing dry mouth on a frequent or constant basis should discuss their full medication list and health history with their dentist or doctor to uncover potential triggers. Certain conditions require medical management.
Effects on Oral Health
When the mouth is not kept moist and cleansed through regular saliva flow, oral health usually does not stay unaffected for long. Some common issues associated with persistent dry mouth include:
Increased risk of cavities. Without saliva, teeth are exposed to environmental acids and sugars for longer periods, promoting decay.
Gum disease progression. Saliva helps flush away bacteria near the gumline. Its absence allows plaque biofilm to thrive and cause gingivitis or periodontitis.
Fungal infections. Dry mouth predisposes to oral thrush (candidiasis) and infections from other opportunistic fungi.
Tooth sensitivity. Enamel partially demineralizes without remineralization from saliva, making teeth super sensitive to hot/cold.
Difficulty speaking or swallowing. Food bolus preparation and movement is aided by saliva. Dryness thickens mucus and causes discomfort.
Bad breath. Decreased airflow and accumulation of debris causes unpleasant odors.
Cracked lips and tongue. Saliva helps keep oral tissues moist and protected from cracking or fissuring.
Those experiencing any of these dental issues associated with dry mouth will benefit from certain preventive and relieving measures.
