Dry Mouth: Causes, Symptoms, and Remedies

Dry mouth, medically known as xerostomia, is a condition that affects many people, yet often goes unnoticed or untreated. At the same time, it may seem like a minor inconvenience, chronic dry mouth can lead to serious oral health issues if not appropriately managed. Understanding the causes, recognising the symptoms, and knowing the remedies can help you maintain good oral health and overall comfort.

What Is Dry Mouth?

Dry mouth occurs when the salivary glands in your mouth don’t produce enough saliva to keep your mouth moist. Saliva plays a vital role in digestion, speaking, swallowing, and protecting the teeth and gums from bacteria. When saliva production is reduced, your oral health becomes vulnerable to decay, gum disease, and discomfort.

Common Causes of Dry Mouth

Several factors can contribute to reduced saliva production. Understanding the underlying causes is essential in treating and managing the condition.

1. Medications

One of the most common causes of dry mouth is medication. More than 400 over-the-counter and prescription drugs can cause dry mouth as a side effect. These include:

• Antihistamines
• Antidepressants
• Diuretics
• Painkillers
• Medicines for high blood pressure or Parkinson’s disease

2. Dehydration

Inadequate fluid intake, especially in hot weather or after exercise, can lead to temporary dry mouth. Excessive alcohol, caffeine, or salty foods can also contribute to dehydration.

3. Medical Conditions

Certain health conditions, such as diabetes, stroke, Alzheimer’s disease, Sjögren’s syndrome, and autoimmune disorders, can affect the salivary glands, leading to dry mouth.

4. Cancer Treatments

Radiation therapy to the head or neck and chemotherapy can damage salivary glands, reducing saliva production either temporarily or permanently.

5. Lifestyle Habits

Smoking or chewing tobacco can affect saliva flow and contribute to dry mouth. Similarly, breathing through your mouth, especially while sleeping, can dry out the tissues.

Symptoms of Dry Mouth

Dry mouth doesn’t just mean a lack of moisture—it can manifest in several uncomfortable ways. Some common symptoms include:

• Constant dry or sticky feeling in the mouth
• Difficulty swallowing or chewing
• Burning sensation on the tongue
• Cracked lips or corners of the mouth
• Sore throat or hoarseness
• Bad breath
• Increased thirst
• Dry or rough-feeling tongue
• Trouble wearing dentures
• Changes in taste

Over time, these symptoms can lead to more serious dental issues such as tooth decay, gum disease, and oral infections like thrush.

Health Risks Associated with Dry Mouth

1. Tooth Decay and Gum Disease

Saliva neutralises acids in the mouth, washes away food particles, and limits bacterial growth. Without it, plaque builds up faster, increasing the risk of cavities and gum disease.

2. Mouth Infections

Dry mouth increases the risk of fungal infections such as oral candida (thrush), especially in denture wearers.

3. Difficulty with Oral Function

People with dry mouth often find it difficult to chew, taste, speak, and even swallow. This can affect nutritional intake and overall well-being.

Remedies and Treatments for Dry Mouth

The treatment for dry mouth depends on its cause. However, some general remedies and strategies can help alleviate symptoms and protect oral health.

1. Stay Hydrated

Drink plenty of water throughout the day to keep your mouth moist. Carry a water bottle and take frequent sips, especially when speaking for long periods or in dry environments.

2. Use Sugar-Free Gum or Lozenges

Chewing sugar-free gum or sucking on sugar-free lozenges can stimulate saliva flow. Look for products containing xylitol, which also helps reduce cavity risk.

3. Avoid Caffeine, Alcohol, and Tobacco

These substances can dry out your mouth and should be avoided or reduced. Opt for caffeine-free and alcohol-free alternatives.

4. Use a Humidifier

Using a humidifier, especially at night, can help keep the air in your room moist, reducing overnight mouth dryness.

5. Oral Rinses and Saliva Substitutes

There are over-the-counter mouthwashes and sprays explicitly designed for dry mouth. Choose alcohol-free options to avoid further irritation.

6. Maintain Excellent Oral Hygiene

Brush twice a day with fluoride toothpaste and floss daily. Regular dental check-ups are essential to monitor and manage any oral issues that arise from dry mouth.

7. Speak to Your GP or Dentist

If medication is the cause, consult your GP to see if alternatives are available. Your dentist may also prescribe a fluoride gel or recommend specific treatments to protect your teeth.
