Xerostomia (ZEER-oh-STOH-mee-ah), commonly known as dry mouth, is a frequent condition in dental practice. It occurs when the salivary glands produce less saliva, leading to dryness and discomfort in the mouth.
Although it may seem minor, xerostomia can significantly impact oral health and long-term dental outcomes. Understanding its causes, symptoms, and treatments is vital for providing optimal patient care.
Consequences: Xerostomia and Periodontal Disease
Saliva is essential for oral health. It lubricates the mouth, neutralizes harmful acids, and removes food particles and bacteria. Without sufficient saliva, patients may experience:
Increased risk of tooth decay and gum disease
Difficulty chewing, swallowing, and speaking
Bad breath (halitosis)
Xerostomia can also affect overall quality of life, causing sleep disturbances, eating challenges, and social anxiety due to bad breath or speaking difficulties.
Causes and Risk Factors
Aging
Aging naturally reduces salivary gland efficiency, which can lead to dry mouth. Older adults are also more likely to take medications that exacerbate this condition.
Medications
Many prescription and over-the-counter medications can cause xerostomia as a side effect. These include:
Antidepressants
Antihistamines
Blood pressure medications
Diabetes medications (e.g., metformin)
Opioid pain medications
Inhalers for asthma and COPD (propylene glycol-related xerostomia)
*We detail all of these in our dental medication database (DMD) available through DentalRx Instant Search!
Radiation Therapy
Radiation for head and neck cancer can damage salivary glands, significantly reducing saliva production. This effect may be temporary or permanent depending on the treatment dose.
Autoimmune Disorders
Conditions like Sjögren’s syndrome directly affect salivary glands, leading to chronic dry mouth. Other autoimmune diseases may contribute indirectly through medication use or systemic inflammation.
CPAP and Dry Mouth
Patients using Continuous Positive Airway Pressure (CPAP) therapy for sleep apnea often experience dry mouth. The airflow can dry oral tissues, especially if the patient breathes through their mouth during sleep. Mitigation strategies include:
Using a CPAP humidifier
Staying hydrated
Saliva substitutes or moisturizing products
Dehydration
Dehydration, whether from illness, inadequate fluid intake, or excessive fluid loss, reduces saliva production. Maintaining proper hydration is essential for managing xerostomia.
Smoking and Nicotine Use
Smoking reduces saliva production and irritates oral tissues, exacerbating dryness and increasing the risk of gum disease and oral cancer. The local effects of nicotine pouches can also decrease saliva production.
HIV and AIDS
Dry mouth is common in HIV-positive individuals, caused either by the virus’s direct effects on salivary glands or side effects of antiretroviral therapy (ART). This can lead to higher risks of tooth decay, oral candidiasis, and gum disease.
Hormonal Changes: Pregnancy and Menopause
Pregnancy: Hormonal changes, increased metabolic demands, and dehydration can lead to xerostomia. Common triggers include gestational diabetes, morning sickness, and medication use. Encouraging hydration and using saliva substitutes can help.
Menopause: Declining estrogen levels during menopause reduce saliva production, increasing the risk of tooth decay, gum disease, and oral infections. Good oral hygiene and hydration can alleviate symptoms.
COVID-19 and Xerostomia
COVID-19 may directly affect salivary glands, reducing saliva production. Dehydration from fever or illness, along with medications like antivirals and steroids, can exacerbate dry mouth. Managing these symptoms is crucial to prevent oral complications.
Diagnosis
A dental professional can diagnose xerostomia through medical and dental history, physical examination, and a salivary flow test. Saliva flow rates are classified as:
Mild: Above 0.2 ml/min
Moderate: 0.1–0.2 ml/min
Severe: Below 0.1 ml/min
Dry Mouth Treatment and Management
Treatment options for dry mouth include:
Over-the-counter saliva substitutes and moisturizing mouthwashes
Prescription medications to stimulate saliva production
Managing underlying medical conditions
Lifestyle changes (e.g., quitting smoking, staying hydrated)
Regular dental check-ups to prevent decay and gum disease
Common products include:
ACT Dry Mouth Lozenges, Mouthwash, and Moisturizing Gum
XyliMelts Mints
Biotene Moisturizing Spray
With updated legislation in British Columbia, pharmacists can now prescribe for conditions like oral candidiasis and aphthous ulcers, offering added value to dental clinics.
Prevention
Preventing xerostomia involves addressing underlying causes and making lifestyle changes. Effective strategies include:
Stay Hydrated: Drink plenty of water throughout the day to maintain proper hydration.
Limit Caffeine and Alcohol: Reduce consumption of these substances as they can contribute to dehydration.
Use a Humidifier: Adding moisture to the air, especially at night, can help alleviate dryness.
Chew Sugar-Free Gum: Stimulate saliva production with sugar-free gum or candies containing xylitol.
Avoid Nicotine Products: Quit smoking or using nicotine to prevent further reduction in saliva production.
Maintain Good Oral Hygiene: Brush and floss regularly to minimize the risk of tooth decay and gum disease.
Choose Saliva-Friendly Foods: Opt for moist, soft foods and avoid dry or salty items that can worsen symptoms.
Use Saliva Substitutes: Over-the-counter saliva substitutes or moisturizing sprays can provide relief.
Review Medications: Work with a healthcare provider to adjust medications that may be contributing to dry mouth.
Schedule Regular Dental Checkups: Scheduling your patient for regular dental check-ups can help identify early signs of xerostomia and related complications.
