Dry Mouth (Xerostomia): Causes, Symptoms & Treatment | Julphar Dental Clinic

Many patients describe dry mouth as a minor inconvenience something that happens occasionally when they’re stressed, dehydrated, or breathing through their mouth. However, when dry mouth becomes persistent, it can signal an underlying issue that deserves attention. In dentistry, this condition is known as xerostomia, and it can significantly impact oral health if left untreated.

What Is Dry Mouth?

Dry mouth occurs when the salivary glands do not produce enough saliva to keep the mouth adequately moist. Saliva plays a vital role in oral health, it helps neutralize acids, wash away food particles, aid digestion, and protect teeth from decay. When saliva flow decreases, the mouth becomes more vulnerable to dental problems.

Common Causes of Dry Mouth:

Dry mouth can result from a variety of factors, including:

• Medications : Antidepressants, antihypertensives, antihistamines, and some painkillers commonly reduce saliva flow.

• Dehydration : Not drinking enough water, excessive caffeine intake, or intense physical activity.

• Mouth breathing : Especially during sleep.

• Medical conditions : Diabetes, autoimmune diseases (such as Sjögren’s syndrome), and certain neurological disorders.

• Radiation therapy : Especially for head and neck cancer patients.

• Smoking and vaping : Both can significantly reduce saliva production.

Signs and Symptoms to Watch For:

Dry mouth doesn’t always feel the same for everyone. Common symptoms include:

• A sticky or dry feeling in the mouth
• Difficulty chewing, swallowing, or speaking
• Burning sensation on the tongue
• Bad breath that doesn’t improve with brushing
• Cracked lips or sores at the corners of the mouth
• Increased tooth decay or gum inflammation

If these symptoms persist, it’s important to seek professional evaluation.

Why Dry Mouth Is a Serious Dental Concern:

Saliva is your mouth’s natural defense system. Without it:

• Cavities develop faster, especially near the gumline
• Gum disease risk increases
• Oral infections, such as fungal infections (thrush), become more common
• Existing dental restorations may fail sooner

In short, untreated dry mouth can silently lead to extensive dental damage.

How Dry Mouth Is Managed in Dentistry?

Treatment may include:

• Reviewing medications in coordination with your physician
• Dietary and hydration advice
• Saliva substitutes or stimulants
• Prescription products to increase saliva flow (when appropriate)
• Customized preventive care plans to protect teeth from decay

Regular dental checkups are essential for patients with xerostomia, even if no pain is present.

Simple Tips to Relieve Dry Mouth at Home:

While professional care is important, these daily habits can help:

• Sip water frequently throughout the day
• Chew sugar-free gum to stimulate saliva
• Avoid alcohol-based mouthwashes
• Limit caffeine and sugary drinks
• Use a humidifier at night if you breathe through your mouth

When Should You See a Dentist?

If dry mouth lasts longer than a few weeks, worsens, or is accompanied by frequent cavities or gum problems, it’s time for a dental evaluation. Early intervention can prevent long-term complications and protect your smile.

A healthy mouth depends on more than brushing and flossing saliva matters.
