Dry mouth, also known as xerostomia, is more than just an uncomfortable feeling of dryness in your mouth. It’s a condition that can significantly impact your oral health and overall well-being. At the Cosmetic Dentistry Center in Brooklyn, New York, we’re here to provide friendly, knowledgeable, and informational insights into what dry mouth is, its causes, and how to manage it effectively.

What is Dry Mouth?

Dry mouth occurs when your salivary glands don’t produce enough saliva to keep your mouth moist. Saliva is essential for maintaining oral health, as it helps with digestion, protects teeth from decay, controls bacteria growth, and enhances your ability to taste and swallow.

Causes of Dry Mouth

Several factors can lead to dry mouth, including:

1. Medications

Many prescription and over-the-counter medications can cause dry mouth as a side effect. Common culprits include antihistamines, decongestants, painkillers, diuretics, and medications for high blood pressure and depression.

2. Medical Conditions

Certain health conditions, such as diabetes, Sjögren’s syndrome, and HIV/AIDS, can affect salivary gland function and lead to dry mouth.

3. Cancer Treatments

Radiation therapy to the head and neck and chemotherapy can damage salivary glands, resulting in reduced saliva production.

4. Aging

As you age, your salivary glands may naturally produce less saliva. Additionally, older adults are more likely to take medications that can cause dry mouth.

5. Lifestyle Choices

Smoking and excessive alcohol consumption can contribute to dry mouth. Using recreational drugs like methamphetamine and marijuana can also reduce saliva production.

6. Nerve Damage

Injury or surgery that causes nerve damage to the head and neck area can affect the salivary glands’ ability to produce saliva.

Symptoms of Dry Mouth

Common symptoms of dry mouth include:

  • A sticky, dry feeling in the mouth and throat
  • Frequent thirst
  • Sores or split skin at the corners of the mouth
  • Cracked lips
  • A dry, rough tongue
  • Difficulty chewing, swallowing, or speaking
  • A burning or tingling sensation in the mouth
  • Bad breath

Complications of Dry Mouth

If left untreated, dry mouth can lead to various complications, such as:

  • Increased risk of tooth decay and gum disease
  • Mouth sores and infections
  • Difficulty wearing dentures
  • Poor nutrition due to difficulty chewing and swallowing

Managing and Preventing Dry Mouth

Here are some tips to help manage and prevent dry mouth:

1. Stay Hydrated

Drink plenty of water throughout the day to keep your mouth moist.

2. Chew Sugar-Free Gum

Chewing sugar-free gum or sucking on sugar-free candies can stimulate saliva production.

3. Use a Humidifier

Using a humidifier, especially at night, can add moisture to the air and help prevent dry mouth.

4. Avoid Tobacco and Alcohol

Quit smoking and limit alcohol consumption to reduce dry mouth symptoms.

5. Use Alcohol-Free Mouthwash

Opt for an alcohol-free mouthwash to avoid further drying out your mouth.

6. Maintain Good Oral Hygiene

Brush your teeth twice a day with fluoride toothpaste, floss daily, and visit your dentist regularly.

When to See a Dentist

If you’re experiencing persistent dry mouth, it’s essential to consult with a dentist. They can help identify the underlying cause and recommend appropriate treatments or lifestyle changes to manage the condition.


Dry mouth is a common but manageable condition that can significantly impact your oral health and quality of life. Understanding its causes and adopting effective strategies to manage it can help you maintain a healthy, comfortable mouth.
