Some Common Reasons For dry Mouth at Night

You might look up the causes of dry mouth while you are sleeping. Here are some common reasons for this problem:

Mouth Breathing:

Your sleeping habits may be causing your dry mouth when you wake up. Many people get dry mouths at night because they breathe through their mouths while sleeping. When the nasal passageways are clogged, mouth breathing is more common. This type of congestion can occur as a result of:

  • Colds
  • Allergies
  • Structural issues including a deviated nasal septum or swollen turbinates.

You breathe via your nose by default. Nasal breathing decreases moisture loss from the soft tissues that line your airways. When you use your lips for breathing, the movement of the air quickly dries you out.

Obstructive Sleep Apnea:

This sleep disorder impairs your capacity to breathe properly while sleeping. When you don’t breathe adequately when sleeping, it’s far more difficult to attain deep, undisturbed sleep. You may snore loudly or breathe through your mouth. Both can cause you to wake up with a dry mouth and affect oral health.

Obstructive sleep apnea is the most usual and common type of sleep apnea. If you have it, it relaxes your throat muscles as you sleep. Your doctor may recommend Continuous Positive Airway Pressure (CPAP) therapy as a treatment.


If you wake up thirsty during the night or have a dry mouth when you wake up, you may be dehydrated. Dehydration occurs when you take less water than your body expels via urine, sweat, or other methods. Dehydration is more common when you do not drink enough water or lose more fluids than usual leads to chronic dry mouth.

For example, diarrhea or sweating due to exercise or hot weather can lead you to lose more fluids. In some situations, dehydration can be exacerbated by underlying medical conditions such as diabetes.

Adverse Drug Reactions:

United States Department of Health and Human Services says that over 400 drugs can impair the body’s ability to generate saliva. People who take their prescriptions at night may notice their dry mouth problems worsen. The American Academy of Oral Medicine states that over 1,100 prescription and over-the-counter (OTC) medications can cause dry mouth.

Blood pressure medications, often known as antihypertensives, and antihistamines are examples of medications that can induce dry mouth.

Diabetes Mellitus:

As someone who has diabetes, many things could make their mouths dry out. It may occur if you are dehydrated or have consistently high blood sugar levels. You may also get a dry mouth due to your medications.

Managing your diabetes will help lower your risk of dry mouth. Discuss your medications with your dentist or your doctor to see if any of them can be changed to help with your dry mouth.

Cancer Treatment:

Chemotherapy medicines can alter the composition and quantity of saliva produced. This could be a short condition, with normal salivary flow returning once the treatment is over. Radiation treatments to your neck and head can damage the salivary glands, resulting in a significant decrease in saliva production. This could be transient or permanent depending on the radiation dose and area treated.

The Aging Process:

As you become older, you may notice more dry mouth. You could be one of the 30% of adults over the age of 65 or nearly 40% of adults over the age of 80 who have this ailment.

Dry mouth may not be caused by aging in and of itself. Dry mouth may be caused by medications you take to treat other health issues. Diabetes, Alzheimer’s disease, and Parkinson’s disease are all illnesses that can cause dry mouth.

Way of life:

Few habits, such as smoking or chewing tobacco and consuming alcohol, might aggravate dry mouth. Using recreational drugs, such as marijuana, may produce temporary dry mouth until the drug’s influence wears off. This can lead to increased plaque, tooth decay and gum disease, mouth sores, Yeast infection in your mouth (thrush), Sores or split skin at the corners of your mouth, or cracked lips.Methamphetamine can induce dry mouth, tooth damage, and a condition known as “meth mouth.”

Avoid Dry Mouth at Night

If you are at risk for midnight dry mouth, you can try various home cures.

Consume Plenty of Fluids:

If your dry mouth is mostly caused by dehydration, consuming enough fluids may lessen your discomfort and keep your mouth wet. Consider putting a glass of water near to your bed at night, in addition to drinking water throughout the day. You can also promote saliva production before going to bed by chewing sugar-free gum or using a non-alcoholic mouthwash.

Make Use Of A Humidifier:

When you are in a low-humidity environment, your dry mouth may worsen. During the night, use a humidifier to keep the air in your bedroom from becoming too dry.

Stop Smoking To Prevent Tooth Decay:

Because smokers create less saliva, stopping smoking may lessen your risk of suffering nighttime dry mouth and help improve bad breath.

Mouth Breathing:

Sleep through your mouth open due to a blocked nose or CPAP therapy. You may be able to relieve dry mouth by treating your nasal congestion or making CPAP adjustments, such as adding a humidifier to your device, in conjunction with your doctor.

Examine Your Medications:

Check the labels of any prescription pills, supplements, or over-the-counter treatments you are using to see if dry mouth, or xerostomia, is indicated as a potential adverse effect. If dry mouth is an adverse effect of a medicine you are taking, do not discontinue it immediately.

Rather than that, schedule an appointment with your doctor. They will be able to assess whether you can safely reduce your prescription dosage, cease the drug, or change your medication regimen to help address night mouth dryness.

Treatment of Dry Mouth:

To address mouth dryness, you may want to begin by maintaining optimal nasal airflow. Good airflow treatment includes:

  • Allergy therapy
  • Surgery to correct anatomical defects
  • CPAP for sleep apnea
  • Mouth moisturizing products such as Biotene

When To Consult A Physician:

If your dry mouth happens often or is very bad, talk to your doctor about it. They’ll want to determine the source of your dry mouth to offer the most effective treatment approach.

Additionally, record any oral symptoms associated with dry mouth. Examine the interior of your mouth for changes such as:

  • Discolored spots
  • Ulcers
  • Gum and tooth decay symptoms

During your appointment, your doctor may:

  • Review your physical symptoms, including looking in your mouth for saliva output, sores, gum and tooth decay, and other conditions;
  • Obtain a blood sample or a biopsy;
  • Determine the amount of saliva you produce; and perform an imaging test to check your salivary glands.
  •  Evaluate all prescription and over-the-counter medications and cures, as well as supplements;
  • Inquire about if you smoke or use recreational drugs;
