Dry Mouth

Your mouth has three main pairs of glands that produce saliva. These are the parotid, submandibular, and sublingual glands. Each gland has a tiny tube, called a duct, that carries saliva to your mouth.

Dry mouth, sometimes called xerostomia, happens when these glands don't make enough saliva to keep your mouth moist. This can be caused by a number of things. Getting older is a common reason. Certain medications, like some blood pressure or allergy drugs, can also cause it. Radiation therapy for cancer is another potential cause. Sometimes, an illness directly affecting the salivary glands themselves is the culprit. Even feeling thirsty or anxious can temporarily lead to dry mouth.

For some people, dry mouth is just a minor inconvenience. But for others, it can significantly impact their overall health. Dry mouth can make it hard to eat and enjoy food. It can also lead to problems with their teeth and gums. For example, without enough saliva, the mouth can become more prone to cavities and gum disease.

Treating dry mouth involves figuring out what's causing it. The treatment will depend on the specific reason for the dry mouth.

Your mouth needs saliva to stay healthy. If you're not producing enough saliva, you might experience several uncomfortable symptoms.

Common signs of low saliva production include:

• Dryness or stickiness in your mouth: This is a frequent complaint, often felt as if your mouth is constantly dry.
• Thick or stringy saliva: Your saliva might feel unusually thick and stringy, almost like a glue-like consistency.
• Bad breath: Without enough saliva to wash away food particles and bacteria, bad breath is a common problem.
• Difficulty chewing, speaking, and swallowing: Dry mouth can make these everyday tasks challenging and uncomfortable.
• Dry, sore, or hoarse throat: A lack of saliva can irritate the throat, leading to dryness, soreness, and even hoarseness.
• Dry or grooved tongue: Your tongue may feel dry and rough, and possibly have grooves or indentations.
• Changes in taste: Saliva plays a role in how we taste food. A decrease in saliva can cause a dulled or altered sense of taste.
• Trouble wearing dentures: If your mouth is dry, dentures may feel uncomfortable or not fit properly.
• Lipstick sticking to teeth: Saliva helps keep your mouth moist, preventing lipstick (or other substances) from sticking to your teeth.

Why is saliva important?

Saliva is vital for oral health. It washes away food particles and sugars, helping to prevent cavities. Saliva also neutralizes harmful bacteria in your mouth, keeping them from causing problems. Without enough saliva, you're more vulnerable to tooth decay and other oral issues.

Beyond oral health, low saliva can also affect:

• Chewing and swallowing: A dry mouth makes it harder to chew and swallow food comfortably.
• Digestion: Saliva contains enzymes that help break down food, so a lack of saliva can impact digestion.
• Taste: The way we taste food relies partly on saliva, so a decrease in saliva can change your sense of taste.

When to see a doctor:

If you experience persistent dry mouth symptoms, it's important to schedule an appointment with your doctor or dentist. They can determine the cause and recommend appropriate treatment options.

If you're experiencing persistent dry mouth, it's a good idea to schedule a visit with your doctor or other healthcare provider.

Dry mouth, also known as xerostomia, happens when your salivary glands don't produce enough saliva to keep your mouth moist. This lack of saliva can have several causes:

Medications: Many different medicines can lead to dry mouth. This includes both prescription and over-the-counter drugs. Common culprits include those used to treat depression, high blood pressure, anxiety, as well as some allergy medications (antihistamines), nasal congestion relievers (decongestants), muscle relaxants, and pain killers. Your body processes medications differently, and some affect the saliva-producing glands more than others.

Aging: As people get older, dry mouth becomes more common. This is often due to a combination of factors, including changes in how the body handles medications, potential nutritional deficiencies, and the presence of other long-term health conditions. These changes can all contribute to reduced saliva production.

Cancer Treatments: Cancer treatments, like chemotherapy and radiation therapy, can significantly impact saliva production. Chemotherapy can temporarily alter the amount and nature of saliva. Radiation therapy, particularly to the head and neck area, can damage the salivary glands, sometimes leading to a long-term decrease in saliva production. The severity and duration of the dry mouth depend on the type and dosage of treatment.

Nerve Damage: Injuries or surgeries affecting the nerves in the head and neck region can sometimes cause dry mouth. Damage to these nerves can disrupt the signals that control saliva production.

Other Health Conditions: Several medical conditions can also contribute to dry mouth. These include diabetes, stroke, mouth infections like thrush, Alzheimer's disease, autoimmune disorders like Sjogren's syndrome, and HIV/AIDS. Each condition can affect saliva production in different ways.

Lifestyle Factors: Certain habits can also contribute to dry mouth. Snoring and mouth breathing, for example, can lead to a dry mouth because the mouth isn't staying moist. Similarly, excessive alcohol consumption and tobacco use (smoking or chewing) can also dry out the mouth.

Street Drugs: Some illicit drugs, like methamphetamine, can cause severe dry mouth, as well as damage teeth. Marijuana use can also lead to dry mouth as a side effect.

If you experience persistent dry mouth, it's important to talk to your doctor. They can help determine the underlying cause and recommend appropriate solutions.

Dry mouth, also known as xerostomia, is a common problem that can affect anyone. Several factors increase the risk of developing dry mouth.

People who are taking certain medications are more likely to experience dry mouth. The medication's label or the doctor will often list this as a potential side effect. This includes many different types of drugs.

Cancer treatment can also cause dry mouth. The treatments themselves, whether chemotherapy, radiation, or other therapies, can damage the saliva glands, leading to reduced saliva production.

Damage to nerves in the head and neck area can also affect saliva production, contributing to dry mouth. Nerve damage might stem from injuries, infections, or other medical conditions.

Various health conditions can increase the risk of dry mouth. For example, people with diabetes, stroke, Alzheimer's disease, Sjögren's syndrome, or HIV/AIDS may experience this problem. These conditions can impact the body's ability to produce saliva normally.

Smoking, chewing tobacco, or using other tobacco products can dry out the mouth. The chemicals in tobacco products can decrease saliva production.

Drinking alcohol in excess can also contribute to dry mouth. Alcohol has a dehydrating effect on the body, which can include the mouth.

Using illegal drugs can also affect saliva production. Some street drugs have side effects that can lead to dry mouth.

Finally, eating sugary or acidic foods and candies can sometimes irritate the mouth and reduce saliva flow. These foods can also promote bacterial growth in the mouth, which can further exacerbate the problem.

Dry mouth, or not having enough saliva, can cause a number of problems. When your mouth doesn't produce enough saliva, it can't properly clean itself. This leads to:

• More plaque buildup and tooth decay: Saliva helps wash away food particles and bacteria that can cause cavities and gum disease. Without enough saliva, these bacteria thrive, leading to a buildup of plaque, which can eventually damage your teeth and gums.

• Mouth sores: Saliva helps keep your mouth moist and lubricated. Without it, the delicate tissues inside your mouth can become irritated and sore.

• Thrush: Thrush is a fungal infection that often occurs in the mouth when the balance of bacteria is disrupted. Dry mouth can make it easier for yeast, a type of fungus, to multiply, leading to a painful and sometimes persistent infection.

• Cracked or sore corners of the mouth (cheilosis) and cracked lips: Saliva helps keep the skin around your mouth moist and healthy. Dry mouth can cause the skin to become dry, cracked, and sore, especially around the corners of the mouth. This can also lead to cracked lips.

• Problems with eating: Saliva is essential for chewing and swallowing food. Without enough saliva, it can be difficult to properly break down food, making it hard to eat and swallow. This can impact your overall nutrition and health over time.

To figure out why your mouth feels dry, your doctor will first ask about your health history and all the medicines you take, even over-the-counter ones. They will also examine your mouth directly.

Sometimes, your doctor might need to do some more tests. These could include blood tests to check your overall health, imaging scans (like X-rays) of your salivary glands (the glands that make saliva), or tests to measure how much saliva you produce. These tests help pinpoint the reason for the dry mouth.

If your doctor thinks a condition called Sjogren's syndrome might be the cause, they might take a small tissue sample (a biopsy) from your salivary glands in your lip. This sample is sent to a lab for further examination. This helps determine if Sjogren's syndrome is the problem.
