Does your mouth feel drier than usual? Are you always thirsty because of that?

Excessive dryness of mouth and thirst are common in pregnancy. A dry or parched feeling in the mouth can cause discomfort and also increase your overall fluid intake. But why does that happen? Is there a way to prevent it? Keep reading this MomJunction post to know what causes dry mouth during pregnancy, its symptoms, and ways to deal with it.


What Is Dry Mouth?

Dry mouth or Xerostomia is a condition that arises due to the reduced flow of saliva from the salivary glands. Saliva is necessary for lubricating the oral tissues and protecting the mucosa. A drop in its production can make chewing, swallowing and tasting difficult, and also lead to tooth decay and various oral infections (1).

There could be various reasons that lead to a dry mouth during pregnancy. Keep reading to know what they are.

What Causes Dry Mouth During Pregnancy?

Here is the list of reasons that may cause dry mouth during pregnancy:

  • Dehydration: Insufficient fluid intake will not produce enough saliva, making your mouth dry (2).
  • Hormonal fluctuation: The changes in the hormonal levels can reduce the flow of saliva (3).
  • Increased blood volume: An increase in the blood volume causes frequent urination that leads to fluid loss from the body (4). Insufficient water content in the body can reduce saliva production.
  • Vomiting: It creates an acidic environment inside the mouth and causes fluid loss from the body. If the saliva is not enough to flush out the acidic fluids, then the mouth gets dry.
  • Lifestyle: Consuming alcohol and beverages containing caffeine, using tobacco products, intake of salty or spicy foods, and mouth breathing can also lead to dry mouth (5).
  • Medications: Medicines used for the treatment of high blood pressure during pregnancy can also lead to dry mouth (6).

Besides a dry mouth, you may also experience certain other symptoms in the case of Xerostomia,

Tips To Relieve Dry Mouth During Pregnancy

Here are a few tips to try at home to ease the discomfort of dry mouth:

  • Take more fluids to keep yourself hydrated. Sucking ice chips also help in moistening your tongue.
  • Try to keep the mouth closed during sleep, as mouth breathing tends to make it dry, especially during the night. If you have a cold or congestion, steam inhalation helps in clearing the airway passages that help you breathe through the nose and not the mouth.
  • A humidifier helps in moistening the room that could help in reducing the dryness of mouth.
  • Sugar-free chewing gum helps in stimulating the salivary glands to secrete saliva.
  • Avoid smoking and consumption of alcohol as it leads to dry mouth.
  • Maintain oral hygiene by brushing, flossing, and rinsing.
  • Cut down on coffee, tea, and aerated drinks as they can make you thirsty.
  • Reduce the intake of salty and sugary food.
