Xerostomia is a condition in which the salivary glands do not produce enough saliva to keep the mouth moist. Saliva is essential- it helps neutralize acids, wash away food debris,  Enamel remineralization and fight bacteria. When saliva is reduced, the mouth becomes a more favorable environment for dental problems.

Symptoms of Xerostomia

Dry mouth can range from mild discomfort to significant functional problems. Common symptoms include:

  • Constant feeling of dryness or “cotton mouth”
  • Burning sensation or sore throat
  • Bad breath (halitosis)
  • Difficulty chewing, swallowing, or speaking
  • Cracked lips
  • Thick, stringy saliva
  • Increased dental cavities, especially along the gumline
  • Waking up frequently at night due to dryness

If left untreated, xerostomia can damage the oral tissues and accelerate tooth decay.

Medication-induced xerostomia increases risk for:

1. Cavities

Without saliva to buffer acids, enamel breaks down faster—leading to rapid tooth decay.

2. Periodontal (gum) disease

Reduced saliva allows plaque to accumulate more quickly, increasing inflammation and bone loss.

3. Oral infections

Patients are more susceptible to candidiasis and bacterial overgrowth.

4. Difficulty wearing dentures

Lack of moisture may cause friction and sores.

How to Manage Dry Mouth: Practical Tips for Relief

While you may not be able to stop the medication, you can reduce its impact.

1. Stay hydrated

Sip water frequently throughout the day. Avoid sugary drinks, sodas, and acidic beverages.

2. Use saliva substitutes

Artificial saliva sprays, gels, or rinses can help lubricate the mouth.

3. Chew sugar-free gum 

4. Avoid alcohol and caffeine

Both worsen dehydration and dry mouth.

5. Use a humidifier at night

Keeping moisture in the air helps with nighttime dryness.

6. Maintain excellent oral hygiene

  • Brush twice daily with fluoride toothpaste
  • Use fluoride rinses or prescription-strength fluoride if needed
  • Schedule regular dental cleanings and exams

Medication-induced xerostomia is common but highly manageable. By understanding the cause and taking the right preventive steps, you can protect your oral health and maintain a comfortable, healthy smile.
