What is Xerostomia? Understanding the Causes and Symptoms of Dry Mouth

What Is Dry Mouth (Xerostomia)?

Dry mouth, also called xerostomia, happens when your mouth does not make enough saliva. Saliva is the liquid that keeps your mouth moist. It helps you chew, swallow, and speak. Without enough saliva, your mouth can feel dry and uncomfortable. Many people experience dry mouth at some point. However, if it lasts, it may need attention.

Common Symptoms and Signs of Dry Mouth

Dry mouth can cause many signs. Sometimes, these symptoms are mild. Other times, they can be more bothersome. For example, you may notice:

A dry, sticky feeling in your mouth

Frequent thirst

Cracked lips or corners of the mouth

Dry or sore throat

Bad breath

Difficulty chewing, swallowing, or speaking

Changes in taste

Burning feeling on your tongue

Because saliva protects your teeth, dry mouth can also lead to more cavities.

Main Causes and Risk Factors

There are many dry mouth causes. Sometimes, it is a side effect of medicine. Other times, it may be due to health problems. Here are some common reasons:

Medications: Many drugs, such as those for allergies, depression, or high blood pressure, can cause dry mouth.

Medical conditions: Diabetes, Sjögren’s syndrome, and HIV/AIDS can lead to dry mouth.

Cancer treatments: Radiation or chemotherapy for head and neck cancers may damage saliva glands.

Nerve damage: Injury to the head or neck can affect saliva production.

Dehydration: Not drinking enough water or losing fluids from fever, sweating, or vomiting can cause dryness.

Lifestyle factors: Smoking or drinking alcohol can make dry mouth worse.

As you can see, several things may increase your risk. Age also plays a role, since older adults often take more medicines.

How Is Dry Mouth Diagnosed?

First, your dentist or doctor will ask about your symptoms. They may check your mouth and teeth. Sometimes, they will ask about your health history and medicines. In some cases, tests may be needed. For example, they might measure how much saliva you make. They may also check for other health problems that cause dry mouth.

Effective Treatment Options for Dry Mouth

There are many xerostomia treatment options. The best choice depends on the cause. However, most people can find relief with a mix of medical care and home remedies. Here are some ways to treat dry mouth:

Change medications: If a drug is causing dryness, your doctor may adjust the dose or switch medicines.

Saliva substitutes: Over-the-counter sprays, gels, or rinses can help keep your mouth moist.

Prescription medicines: Some drugs can help your body make more saliva.

Treat underlying conditions: Managing diabetes or other health issues may improve dry mouth.

In addition, home remedies can offer relief. For example, sipping water often or chewing sugar-free gum can help.
