If you live with diabetes, you’re likely familiar with the impact that high blood sugar levels can have on different areas of health. But one symptom you may not expect is dry mouth, known medically as xerostomia. While it might seem like a minor inconvenience at first, chronic dry mouth can lead to a host of issues that impact your daily life and long-term health. The connection between diabetes and dry mouth is significant because it’s not only a common symptom but also a condition that can lead to complications if left unmanaged. For people with diabetes, saliva does more than just moisten the mouth—it serves as a protective agent, defending against bacteria, aiding digestion, and helping maintain oral health. When saliva production is reduced, the mouth becomes more vulnerable to problems like cavities, gum disease, and infections. Moreover, dry mouth can make everyday activities such as eating, speaking, and even sleeping uncomfortable.
In this article, we’ll dive into the link between diabetes and xerostomia, explore why people with diabetes are more susceptible to dry mouth, and discuss practical ways to manage this condition effectively. Understanding xerostomia’s impact and taking proactive measures can make a significant difference in maintaining comfort, oral health, and overall quality of life for individuals managing diabetes.
The Link Between Diabetes and Xerostomia
Diabetes is a condition that affects how your body processes glucose, leading to elevated blood sugar levels. This increase in blood glucose can contribute to dehydration, one of the primary reasons people with diabetes experience xerostomia. Here’s how diabetes contributes to dry mouth:
High Blood Sugar Levels: When blood sugar levels are elevated, the body tries to flush out excess glucose through increased urination. This loss of fluids can lead to dehydration, reducing saliva production and causing dry mouth. For people with diabetes, this can become a repeating cycle. High blood sugar causes dehydration, which reduces saliva production, which then makes it harder for the mouth to maintain its natural moisture.
Medication Side Effects: Many people with diabetes take medications that can list dry mouth as a side effect, especially those for blood pressure or other related conditions.
Neuropathy and Salivary Glands: In some cases, diabetes can damage the nerves that control the salivary glands, which can decrease saliva production.
Increased Risk of Infections: People with diabetes are more susceptible to infections, such as oral thrush, which can lead to or worsen dry mouth symptoms.
Xerostomia, or chronic dry mouth, is a common symptom among individuals with diabetes. It not only impacts daily comfort but can also exacerbate the risk of oral health problems like gum disease, cavities, and infections. Here's a look at the connection between diabetes and xerostomia, why dry mouth is more common in people with diabetes, and some ways to manage it effectively.

Why Xerostomia is a Concern for People with Diabetes
The mouth relies on saliva for many functions, including protecting the teeth and gums from bacteria, aiding in digestion, and preventing infections. Without adequate saliva, people with diabetes face several potential complications:
Tooth Decay and Gum Disease: Saliva helps wash away food particles and bacteria, reducing plaque buildup. Low saliva levels increase the risk of cavities and gum disease.
Oral Infections: Dry mouth can make the mouth more hospitable to infections, especially fungal infections like oral thrush, which is more common among people with diabetes.
Difficulty with Dentures: For those who wear dentures, dry mouth can cause discomfort, making it challenging to keep dentures in place and use them comfortably.
Impact on Blood Sugar Control: Oral infections and inflammation can make it harder to control blood glucose levels, creating a cycle that exacerbates both diabetes and xerostomia symptoms.
Managing Xerostomia for People with Diabetes
While there’s no cure for xerostomia, there are effective strategies to manage it, reduce discomfort, and protect your oral health:
Keep Your Mouth Moist: Drinking water throughout the day is essential for everyone, but especially for people with diabetes. Aim to drink small sips regularly to keep your mouth moist. Chewing sugar-free gum or using sugar-free lozenges can stimulate saliva production without raising blood sugar levels. Over-the-counter saliva substitutes or mouth sprays can provide temporary relief from dryness. These products can help moisten the mouth without affecting blood sugar.
Adjust Diet: Avoid foods and beverages that can worsen dry mouth, such as caffeine, alcohol, and highly salty or acidic foods. Opt for softer foods that are easier to chew and swallow.
Maintain Good Oral Hygiene: Brush with a fluoride toothpaste, floss daily, and use an antibacterial mouthwash to reduce the risk of decay and gum disease. A fluoride rinse or gel may also help protect against cavities.
Limit High-Sugar Foods: High blood sugar can worsen dry mouth, so it's essential to avoid sugary snacks and drinks, which can also contribute to cavities and
gum problems.
Control Blood Sugar Levels: Managing your diabetes effectively with a balanced diet, regular exercise, and adherence to medication can help reduce dry mouth symptoms by keeping blood sugar levels stable.
Use a Humidifier: A humidifier can help add moisture to the air, especially at night, which may help keep the mouth from feeling excessively dry during sleep.
Regular Dental Checkups: People with diabetes should visit their dentist regularly to monitor and address any oral health issues early on. Professional cleanings and fluoride treatments can also help prevent complications related to dry mouth.
When to Seek Medical Advice
If dry mouth symptoms persist, it’s essential to consult both your doctor and dentist. They can help determine if there are any underlying issues contributing to your dry mouth and recommend treatment options. Persistent xerostomia may require a closer look at your medications or adjustments in your diabetes management plan. Xerostomia is a common but manageable condition among people with diabetes. Staying hydrated, practicing good oral hygiene, and controlling blood sugar levels are key to preventing dry mouth-related complications. By taking proactive steps, individuals with diabetes can manage xerostomia effectively, reducing discomfort and maintaining good oral health.
