How to Stop Dry Mouth While Sleeping

Posted by On 12-06-2022

Do you find it difficult to talk because your mouth is so dry? Do you wake in the middle of the night with a dry, sore throat? Do you need water as soon as you wake up in the morning? Do you find you have bad breath even though you are brushing, flossing, and using mouth wash every day? If you answered yes to any of these questions you might be one of the millions of people that are waking up with dry mouth every day.

Not only does dry mouth get you up out of bed in search of a glass of water at night, but it also comes with some risks. Although dryness might seem harmless, it can actually lead to a number of issues including an increased risk of tooth decay and gum disease. Also known as xerostomia, the lack of saliva in your mouth is not normal. There are a number of causes and risks associated with the bacteria left in your mouth when you are not producing the proper amount of saliva. Here is everything you should know about dry mouth and how to stop it while you sleep.

What is dry mouth?

Xerostomia — or the much easier to pronounce term dry mouth — is an actual health condition. It affects the salivary glands in your mouth so that you are unable to produce the saliva required to keep your mouth wet. A wet mouth is very important as it neutralizes the acids that are produced by bacteria. Saliva helps limit bacteria by washing away food particles so bacterial growth is not allowed to run rampant in your mouth and throat.

Why do you need saliva?

Saliva helps prevent tooth decay, enhances your ability to taste, and also allows you to chew and swallow your food more easily, which in turn aids in digestion. When you don’t have enough saliva, it is more than just a nuisance. It affects the health of your teeth and gums, your appetite, and also interferes with your ability to enjoy food.

Without enough saliva, the build-up of bacteria can lead to tooth decay, infections and tooth loss. Saliva production is also necessary to help keep your breath fresh. Bacteria and particles of food trapped in your mouth can lead to bad breath.

Sleep-Related Dry Mouth

Sleep-related xerostomia is noticeable when you have either a dry mouth, dry sore throat or both when you wake up. In fact, it is often the need for water that can cause you to wake during the night.

As much as 23 percent of Canadians suffer from sleep-related dry mouth. Although we tend to produce more saliva when awake, saliva production should continue throughout sleep albeit it at a diminished level. It is believed a slowdown of saliva production during sleep is related to our circadian rhythm. Salivary secretion and swallowing involve rhythmic masticatory muscle activity that takes place as we sleep. During sleep, saliva provides the necessary lubricants needed to protect your oral tissue as well as the health of your esophagus.

Symptoms of Dry Mouth

Common symptoms of dry mouth include:

  • Dryness
  • A sticky feeling in your mouth
  • Thick saliva
  • Stringy saliva
  • Bad breath
  • Difficulty chewing, speaking and swallowing
  • Hoarseness
  • Dry or sore throat
  • Dry tongue
  • Tongue grooves
  • Unpleasant taste or changes to the taste of food
  • A bad taste in your mouth
  • Increased discomfort when wearing dentures

Do you have dry mouth?

You can ask yourself a few questions to determine if you have dry mouth:

  • Are you taking more than two medications a day?
  • Do you feel your mouth is dry during the day despite drinking fluids?
  • Do you find you are constantly eating or drinking to avoid the discomfort of a dry mouth?
  • Do you awaken at night feeling thirsty or needing water?
  • Does your mouth become dry when you are speaking?

If you answer yes to any or all of these questions, chances are you are suffering from dry mouth.

Common Causes of Dry Mouth

Although dry mouth can be due to xerostomia, this is uncommon. Instead, it is more likely caused by one of the following:

  • Antidepressants, high blood pressure medications, antihistamines, decongestants, muscle relaxants, beta-blockers, anti-hypertensives, diuretics and pain medications
  • Ageing
  • Chemotherapy
  • Damage to the neck or head due to radiation treatment, surgery or injury
  • Nerve damage in the head and neck
  • Diabetes, stroke, thrush, Alzheimer's disease, autoimmune diseases
  • Snoring and breathing with your mouth open
  • Tobacco, alcohol, and recreational drug use such as methamphetamine and marijuana
  • Caffeine

Complications of Dry Mouth

If left untreated, dry mouth can lead to the following complications:

  • Increased plaque, tooth decay and gum disease
  • Mouth sores
  • Yeast infection of the mouth
  • Sores in and or around the mouth
  • Split skin at the corners of the mouth
  • Cracked lips
  • Poor nutrition due to difficulty chewing and swallowing

How to Stop Dry Mouth at Night

Living with dry mouth is not fun. It is uncomfortable and can also make you self-conscious due to bad breath. As soon as you start feeling dry mouth either when you wake up, or throughout the day, it is important to take steps that will return moisture. This will help you avoid the risks associated with dry mouth.

The good news is there are a number of solutions that can help you stop dry mouth at night including:

  • Remain hydrated throughout the day by drinking plenty of water
  • Use a fluoride toothpaste
  • Use dry mouth oral rinse
  • Use dry mouth moisturizing spray
  • Avoid spicy and acidic foods before bed
  • Quit smoking
  • Limit alcohol intake
  • Avoid recreational drug use
  • Speak to your pharmacist about regular prescription and over the counter medications you take to learn more about side effects and potential changes to medications if dry mouth persists

If dry mouth persists you can speak to our office. We can identify the cause and recommend changes to your oral health regime to keep you more comfortable.

    Hello, I’m HUGO NEREA. For certainty this piece of information will change your life or that of your loved one. This is a testimony of how I got cured using doctor White herbal medicines. I never thought this could be possible because I am a very skeptical person. I told myself It was medically impossible when i first saw the testimony of a woman who was cured of AIDS and HPV by doctor White. Her testimony came at a time i was in desperate need to end my herpes regular crises after being engaged to my lover who fixed our wedding in 3months you will understand how desperate I was. Because i was confused, helpless and ready to eat my own faeces for a cure, i decided to write him from where he gave me his oo2349o91844595. For 3years i had pains and itching around my genitals, Uncontrollable oozing discharge and blisters not to mention the pain associated with urinating. After i contacted doctor White and told him about my health. He promised to heal me, After doing everything he asked me to do, he prepared herbal cures and sent them to my address which arrived on the 5th working day. I took the medicines according to the prescriptions, in few days of using the medicines i noticed great positive change in my health, today I am cured, living a normal life, totally free from this virus and married. If you have health problems, or truly want to help a sick fellow don’t hesitate to contact doctor White. My experience with White convinced me that some humans are more gifted than others. He has been tested and trusted to cure the following…

    Hello! I’m very excited to share what worked for me to everyone. I’m completely cured from my HSV1&2 with the use of natural medicine. I have used Oregano oil, Coconut oil, Acyclovir, Valacyclovir, Famciclovir and some other products/supplements and it hasn’t helped ever since I was diagnosed. I got outbreaks frequently and was completely devastated and I went online for a possible cure and how to get rid of Herpes. On a fateful day after taking my bath, I took my phone and was going through some research, I bumped into a testimonial of a Herbs doctor { Dr Awase } who cures diverse diseases/viruses with Herbal medication. I was hopeful but also doubted the claim. But after a while I thought “what do I have to lose?” so I decided to reach out. He prepared a cure using roots and herbs which I steadily took for 14days as prescribed by him. I am quite glad I decided to reach out because I am totally cured from Herpes after a medical checkup was done by my Dr. So I’ve decided to make a quick testimony for anyone out there who is probably suffering from an illness they can’t handle to reach out to Dr Awase. He specializes in curing lots of illnesses such as HIV, ENDOMETRIOSIS, PCOS, OVARIAN CYST, IBS, INFERTILITY CANCER, AUTISM and lots more. I’m here to let you all know that you can also be cured just like me and you don’t have to live with any sort of illness for the rest of your life. To reach out, Contact him via

    No matter how much water I drink, before going to bed, during the night and immediately after, my mouth and lips fell like dry cardboard. As soon as I have my breakfast, it’s gone. Dry mouth relief pastilles may help. SALIVAX produced in Sweden by Jemedic AB, widely distributed in many countries. Not a cure but provide relief. Swiss herbal RICOLA sweets can also be helpful, but not a cure, just short term relief. RICOLA have a web address

    Just use nasal strips. Available at any pharmacy, nasal strips gently hold your nostrils open while you sleep. Evidence suggests that they may be effective at discouraging mouth breathing.
