By Aloha Dental | March 20, 2025

Dry mouth happens when your salivary glands don’t produce enough saliva. Saliva keeps your mouth moist, helping with digestion, and protecting your teeth from decay. Saliva helps rinse away food particles and bacteria, keeping your mouth healthy. Without enough saliva, your mouth may feel like it’s constantly drying out.

Do you need to care about your dry mouth?

Yes, dry mouth can be more than just an annoying feeling. When your salivary glands don’t produce enough saliva, it can lead to several oral health issues such as tooth decay, gum disease, speaking, swallowing and tasting food.

Symptoms of Dry Mouth

If you have it, you might notice that your

  • Mouth feels sticky or dry
  • Swallowing
  • A sore throat
  • Bad breath
  • Hard to speak clearly

The lack of saliva means there’s less protection for your teeth, and it becomes easier for plaque and bacteria to build up. If you experience any such symptoms, do not ignore it. Consult your dentist to address the issue early and prevent further oral health problems.

Common Causes of Dry Mouth

Dehydration

One of the simplest causes of dry mouth is dehydration. When your body doesn’t have enough water, your salivary glands don’t produce enough saliva. It’s easy to overlook, but if you’re not drinking enough water throughout the day, your mouth can feel dry.

Medications

Did you know that certain medications can make your mouth feel dry? Many prescription drugs can reduce saliva production as a side effect. If you’ve recently started a new medication, dry mouth might be one of the side effects.

Health Conditions

Some health conditions are linked to dry mouth. For example, diabetes, autoimmune disorders, or sleep apnea can affect how much saliva your body produces. If you’re dealing with any of these conditions, dry mouth could be an unexpected result.

Lifestyle Factors

Habits like smoking or drinking alcohol can also contribute to dry mouth. Both smoking and alcohol can dry out your mouth and affect your salivary glands. Similarly, consuming too much caffeine can have the same effect.

Aging

As we get older, it’s not uncommon to experience a decrease in saliva production. Aging, combined with certain medications, can make dry mouth more likely in older adults.

How to Manage and Relieve Dry Mouth

Stay Hydrated

The easiest way to manage dry mouth is to drink plenty of water. Keeping your body hydrated helps maintain saliva production. It also helps to sip water regularly throughout the day, especially if you’re talking or eating.

Saliva Substitutes

There are over-the-counter products like mouth sprays, gels, and lozenges designed to mimic natural saliva. These can be helpful if you’re struggling to keep your mouth moist, especially during the night.

Oral Care Tips

Brushing your teeth and gums regularly is even more important if you have a dry mouth. Use fluoride toothpaste and mouthwash to keep your mouth healthy. Don’t forget to floss daily to remove food particles and plaque buildup.

Dietary Changes

Some foods can help stimulate saliva production. Chewing sugar-free gum or sucking on sugar-free candies can keep your mouth moist. Avoid spicy, salty, or acidic foods that can irritate a dry mouth.

Lifestyle Modifications

If you smoke or drink alcohol, reducing these habits may help improve your dry mouth symptoms. Limiting caffeine can also make a big difference.

Medications

If your dry mouth is severe or persistent, talk to your doctor or dentist. There are prescription medications that can help increase saliva production. Your healthcare provider will be able to offer guidance on the best treatment options for you.

When to See a Doctor or Dentist
