Dry Mouth in Pregnancy: Causes, Symptoms & Treatment

Pregnancy comes with a long list of weird symptoms. From morning sickness to food cravings, the list is almost endless. Sometimes, pregnancy even comes with a symptom as unusual as dry mouth.

Although it is not one of the popular pregnancy symptoms, dry mouth is not a strange occurrence for women in this period.

In this article, you’d find all you need to know about dry mouth in pregnancy; the causes, symptoms, and treatment options.

What is Dry Mouth in Pregnancy?

Here’s the fact: Saliva is a really important feature in your mouth. It helps you digest food, moistens your mouth, and protects it by controlling its bacteria and fungi population.

During pregnancy, the hormone fluctuations that come with your growing baby can affect salivary secretion in your mouth. In addition, reduced salivary secretion during pregnancy may also be a sign of gestational diabetes.

Dry mouth pregnancy is a really important condition because it increases your risk of mouth infections (like thrush), tooth decay, and gum disease.

What Causes Dry Mouth During Pregnancy?

Like every other weird pregnancy symptom, many factors contribute to the development of dry mouth during pregnancy.

Some of them include:

1. Dehydration

This is what happens when your body loses more water than it gets. During pregnancy, vomiting ( during morning sickness) and diarrhea can cause dehydration. Therefore, it is advisable to drink lots of water during the entire period of your pregnancy.

In fact, we recommend an average of 8 cups daily.


In addition to causing dry mouth, dehydration during pregnancy can also lead to persistent headaches, dark yellow urine, dizziness, and extreme fatigue.

2. Side Effect of Certain Medications

Sometimes, certain prescribed medications during pregnancy can alter the amount of saliva in your mouth.  For example, drugs used to treat hypertension and anti-emetics (for nausea treatment) can cause dry mouth.

In addition, dry mouth may also be a side effect of sedatives and muscle relaxants.

3. Gestational Diabetes

As we mentioned earlier, gestational diabetes is a leading cause of dry mouth during pregnancy. This condition, which raises your blood sugar level, only occurs during pregnancy. In this post, we talked about the signs, symptoms, and management of gestational diabetes.

4. Lifestyle Choices

  • Smoking
  • Caffeine Intake
  • Tobacco Consumption
