By Anaya Sethi|2 - 3 mins read| April 01, 2025

While morning sickness, fatigue, and food cravings are often a common part of pregnancy, many pregnant women may also experience dry mouth.

If you wake up with a parched mouth, constantly feel the need to sip water, or notice a sticky feeling in your mouth, know that nearly 20 percent of pregnant women experience dry mouth, also known as xerostomia, at some point during their pregnancy. 

So, why does this happen, and how can you manage it? Read this article to know everything you need to know about dry mouth during pregnancy.

What Causes Dry Mouth During Pregnancy?

Several factors contribute to dry mouth while you’re expecting. Here are some potential factors associated with dry mouth during pregnancy.

Hormonal Changes

Pregnancy hormones, especially progesterone and estrogen, alter saliva production, thereby leading to a dry, sticky mouth.

Increased Fluid Demand

Your body needs more water to support increased blood volume, and during pregnancy, this need rises by almost 50 percent , sometimes leading to dehydration and dry mouth.

Frequent Urination

Pregnant women urinate more due to increased kidney function, which can cause fluid loss and dehydration, resulting in a dry mouth.

Gestational Diabetes

Did you know that around 2-10 percent of pregnancies are affected by gestational diabetes?

Increased blood sugar levels can cause excessive thirst, dry mouth, and frequent urination. 

Mouth Breathing

Nasal congestion, common in pregnancy, may also force you to breathe through your mouth, which can dry out saliva.

Symptoms of Dry Mouth in Pregnancy

Dry mouth can come with several uncomfortable symptoms, including.

  • Persistent dryness or stickiness in the mouth
  • Bad breath
  • Cracked lips or dry throat
  • Sore tongue or burning sensation
  • Difficulty swallowing or speaking

If left untreated, dry mouth can lead to an increased risk of cavities and gum disease.

Tips to Manage Dry Mouth During Pregnancy

Dry mouth can effectively be managed with simple lifestyle changes. Here’s what you can do to keep your mouth moist and comfortable:

Stay Hydrated

Aim to drink at least 8-12 cups or 2-3 liters of water daily. Simply keep a water bottle handy and sip throughout the day.

Avoid Dehydrating Beverages

Cut down on caffeinated drinks, including coffee, soda, and energy drinks, as they contribute to dehydration. You can even try herbal teas or infused water.

Keep Your Mouth Moist

Suck on sugar-free lozenges or ice chips to stimulate saliva production. Besides, chewing sugar-free gum can also help.

Practice Good Oral Hygiene

Brush your teeth twice daily and floss regularly. Also, using an alcohol-free mouthwash prevents further drying.

Use a Humidifier

If dry air worsens your symptoms, you can consider using a humidifier in your bedroom to keep moisture levels balanced, especially at night.

Eat Water-Rich Foods

Include foods such as cucumbers, watermelon, oranges, and yogurt, which have high water content to help keep you hydrated.

When to See a Doctor?

While mild dry mouth is common, persistent dryness can be a sign of an underlying condition. It is best to consult your doctor if you experience the following signs:

  • Extreme thirst and dry mouth even after drinking water
  • Burning sensation in your mouth that doesn’t go away
  • Frequent urination and blurred vision
  • Swollen gums or oral infections

Conclusion

Dry mouth during pregnancy may be uncomfortable, but it’s usually temporary and can be managed easily with some lifestyle and dietary changes. By staying hydrated and maintaining good oral hygiene, you can keep your mouth feeling fresh and comfortable.
