If you’ve ever felt your mouth stick to your teeth or struggled to swallow because it’s so dry, you know how uncomfortable it can be. Occasional dry mouth can happen if you’re dehydrated or anxious, but when it becomes a constant problem, it may be a sign of xerostomia, a condition that needs attention because xerostomia makes you more vulnerable to gum disease, tooth decay, and other dental issues.
What Is Dry Mouth (Xerostomia)?
Dry mouth, or xerostomia, happens when your salivary glands don’t produce enough saliva to keep your mouth moist and healthy. Saliva isn’t just for comfort, it protects your teeth and gums, washes away food particles, and helps fight bacteria.
While everyone experiences occasional dryness, chronic dry mouth can lead to more serious dental issues such as cavities, gum disease, mouth sores, and bad breath. It can also make eating, speaking, and swallowing more difficult.
Common Symptoms of Dry Mouth
- Sticky or dry feeling in the mouth and throat.
- Difficulty speaking, eating, or swallowing.
- Bad breath that doesn’t go away.
- Sore or pain on the tongue, lip and mouth.
- Cracked lips or mouth sores.
- Dry nose or hoarseness.
- Increased thirst.
- Trouble wearing dentures.
- Constant sore throat.
- Taste disorders.
Severe symptoms could include dry eyes and skin, skin rash and joint pain. If left untreated, dry mouth can also lead to tooth decay, gingivitis, and oral infections.
What Causes Dry Mouth?
There are many reasons why your salivary glands might slow down:
- Medications: Hundreds of prescription and over-the-counter drugs list dry mouth as a side effect. Common culprits include antihistamines, antidepressants, Anticholinergic, anti-anxiety medications, parkinson’s disease medications, decongestants, some pain medicines and certain blood pressure drugs.
- Medical Conditions: Diabetes, Sjögren’s syndrome, Alzheimer’s disease, and stroke can all impact saliva production.
- Cancer Treatments: Radiation to the head and neck or certain chemotherapy drugs can damage salivary glands.
- Dehydration & Lifestyle: Not drinking enough water, smoking, and mouth breathing can also contribute to dryness.
How Your Dentist Can Help
At Presidential Dental Care, we don’t just treat your teeth, we look at your overall oral health.

We may also measure your saliva flow and check for cavities or gum issues that dry mouth can cause.
Managing and Treating Dry Mouth (Xerostomia)
How is Dry Mouth Treated?
The primary goal of dry mouth treatment is to increase saliva production and protect your teeth and gums. More saliva means a healthier mouth, fewer cavities, and better overall comfort.
The exact treatment depends on what’s causing your dry mouth:
- Medication-related dry mouth: If a prescription is the culprit, your healthcare provider may adjust your dosage or recommend an alternative. Never stop or change medication without medical guidance.
- Health conditions: If xerostomia is linked to an underlying condition like diabetes or Sjögren’s syndrome, treating the root cause can often improve symptoms.
Professional Treatment Options
Your dentist or physician may recommend:
- Prescription-strength lozenges such as Sorbitol to keep your mouth moist.
- Saliva stimulators like Cevimeline or Pilocarpine to help your glands produce more saliva.
- Surgical salivary gland repair (in rare cases).
Simple Tips to Relieve Dry Mouth at Home
- Drink water throughout the day.
- Chew sugar-free gum or lozenges to stimulate saliva.
- Use alcohol-free fluoride mouth rinses.
- Use Enzyme-based dry mouth products like Biotène®.
- Suck on ice cubes or sugarless ice pops for quick relief.
- Avoid tobacco, alcohol, and sugary drinks.
- Keep your lips moisturized to prevent cracking.
- Take medications that may cause dry mouth in the morning instead of at night, since experiencing dry mouth while you sleep can increase the risk of cavities and other dental problems.
- Use a cool-mist humidifier at night, especially if you breathe through your mouth.
Avoid These If You Have Dry Mouth:
- Smoking.
- Alcohol and carbonated drinks.
- Acidic, spicy, or sugary foods.
- Overusing antihistamines or decongestants (when possible).
When to See a Dentist
