Dry mouth, medically known as xerostomia, can stem from a variety of causes, and its effective management typically involves a three-pronged approach: addressing the underlying medical conditions, diligently preventing tooth decay, and, whenever possible, stimulating saliva production.
Managing Underlying Causes:
Often, dry mouth is a side effect of medications commonly prescribed for conditions such as depression, anxiety, pain, allergies, diarrhea, urinary incontinence, and Parkinson's disease. In such cases, your healthcare provider may consider adjusting your medication, either by changing the dosage or prescribing an alternative. However, if the cause of dry mouth is irreversible, such as salivary gland damage from radiation or chemotherapy, or a consequence of a chronic disease like Sjögren's syndrome, Alzheimer's disease, or stroke, the focus of treatment will shift to strategies for increasing saliva flow.
Preventing Tooth Decay Due to Dry Mouth:
Saliva plays a crucial role beyond just aiding digestion; it acts as a natural cleanser for the mouth, protecting against tooth decay and gum disease. With reduced saliva, the risk of these oral health issues escalates. Therefore, individuals with dry mouth must commit to exceptional oral hygiene practices:
Brush your teeth at least twice daily, ideally after every meal and before bedtime.
Floss your teeth every day.
Always use a fluoride-containing toothpaste.
Schedule dental check-ups and cleanings at least twice a year. Your dentist might also recommend daily use of fluoride rinses or gels for added protection.
Increasing Saliva Flow:
For individuals experiencing dry mouth, several options can help stimulate saliva production or provide relief:
Artificial Saliva Products: Over-the-counter artificial saliva products, available as rinses or sprays, can offer temporary relief. Specialized toothpastes, mouthwashes, and moisturizing gels formulated for dry mouth are also available; consult your dentist or doctor for recommendations.
Prescription Medications: Your healthcare provider may prescribe medications like Salagen (pilocarpine), which enhances natural saliva production. Another FDA-approved prescription drug, Evoxac (cevimeline), is specifically used to treat dry mouth in patients with Sjögren's syndrome, an autoimmune disorder characterized by dry eyes, dry mouth, dry skin, and muscle pain.
Future Treatments: Research is ongoing into innovative treatments, including methods to repair damaged salivary glands and the development of implantable artificial salivary glands.
Self-Management Strategies for Dry Mouth:
Beyond medical interventions, several lifestyle adjustments can help minimize the discomfort of dry mouth:
Hydration: Drink water frequently throughout the day to keep your mouth moist and help loosen mucus. Keep a water bottle handy and by your bedside at night.
Saliva Stimulation: Suck on sugar-free hard candies, ice chips, or sugar-free popsicles. Chewing sugarless gum (especially those with xylitol) can also stimulate saliva flow. While these can be helpful, use them in moderation as even sugar-free options can slightly soften tooth enamel. Avoid chewing ice, as it can damage teeth.
Food Modifications: Moisten foods with broths, soups, sauces, gravies, creams, and butter or margarine. Opt for soft, moist foods that are cool or at room temperature.
Avoid Irritants: Steer clear of commercial mouth rinses or mouthwashes containing alcohol or peroxide, as these can further dry out your mouth.
Dietary Considerations: Limit salty foods, dry foods (e.g., crackers, toast, cookies, dry breads, dry meats, dried fruit, bananas), and foods and beverages high in sugar.
Beverage Choices: Avoid alcoholic and caffeinated drinks (coffees, teas, some colas, chocolate-containing drinks), as they contribute to dehydration and dry mouth. Also, acidic beverages like fruit juices (orange, apple, grape, grapefruit) and tomato juice should be minimized due to potential irritation.
Additional Tips:
Reduce intake of spicy or salty foods to prevent pain in a dry mouth.
Quit smoking.
Use a lip moisturizer to prevent chapping and irritation.
Brush teeth and gums with a soft-bristled toothbrush. Rinse your mouth before and after meals with plain water or a mild homemade rinse (8 ounces water, ½ teaspoon salt, ½ teaspoon baking soda). Use a fluoride toothpaste.
Utilize a humidifier, especially at night, to increase ambient humidity in your home.
