Dry mouth, or xerostomia, is a condition where saliva production is reduced, leading to an uncomfortable dryness in the mouth. While it may seem like a minor issue, dry mouth can significantly impact overall health.
Saliva plays an important role in protecting teeth from cavities, aiding digestion, enhancing taste, and facilitating swallowing and speaking. Reduced saliva production, therefore affects all these functions.
Causes of dry mouth
- Medications: Many medications reduce saliva flow. These include painkillers, antihistamines, antidepressants, antianxiety medications, and neurological drugs.
- Aging: As we age, saliva production can decrease. Older adults also tend to take more medications that contribute to dry mouth.
- Tobacco: Smoking or chewing tobacco can lead to dry mouth.
- Nerve damage: Injuries or surgeries in the head and neck area can damage nerves and reduce saliva production.
- Cancer therapy: Chemotherapy can temporarily affect saliva quantity and quality. Radiation in the head or neck area may damage salivary glands permanently or temporarily, depending on dosage and region.
- Other health conditions: Dry mouth can result from diabetes, autoimmune diseases like Sjögren’s syndrome, or HIV. Strokes or Alzheimer’s may also cause the sensation of dry mouth, even with normal saliva levels. Mouth breathing and snoring are also common causes.
Consequences of dry mouth:
- Increased plaque, cavities, and gum disease
- Mouth sores
- Fungal infections
- Cracked lips and sores at the corners of the mouth
- Coated tongue
- Difficulty chewing, swallowing, and speaking
Tips for managing dry mouth:
- Talk to your doctor about adjusting any medications that cause dry mouth
- Maintain thorough and regular oral hygiene
- Visit your dentist at least twice a year
- Drink plenty of water throughout the day in small sips
- Use water while eating to help chew and swallow
- Chew sugar-free gum to stimulate saliva production
- Consume sour foods to boost saliva flow
- If you must drink coffee, always follow it with a glass of water
- Avoid alcohol and tobacco
- Breathe through your nose whenever possible
- Keep lips hydrated
- Avoid sugar, spicy and overly seasoned foods
- Use fluoride toothpaste and alcohol-free mouthwash
