Dry Mouth Home Remedy: Why It Happens & How to Fix It

Editor: Laiba Arif on Apr 01,2025

 

Feeling dryness in your mouth, especially at night, can be quite annoying and disrupt your sleep. Known in the medical community as xerostomia, this condition develops when saliva production decreases. This can cause a dry feeling, difficulty swallowing, and a higher chance of developing oral health problems. Although some dry mouth is normal occasionally, a regular dry mouth may signal an underlying problem.

This guide covers common causes of xerostomia dry mouth at night as well as home remedies for dry mouth to help you get a good night's sleep!

Dry Mouth: Why You Need Saliva

Saliva is essential to keeping the mouth healthy. It assists in digestion, stops the growth of bacteria, and keeps the mouth moist. When saliva production slows, you may feel dryness, bad breath, and stickiness in your mouth. The first step in finding an effective dry mouth home remedy is to identify what causes dry mouth in the first place.

Causes of Xerostomia Dry Mouth at Night

There are several reasons why xerostomia can occur during sleep. Here are some of the most frequent dry mouth causes:

Dehydration

Dehydration is one of the main causes of dry mouth at night. Your body needs enough water to be able to produce saliva. These factors can lead to dehydration:

  • Four in five people admit they dehydrate themselves by not drinking enough water throughout the day
  • Over-consumption of alcohol or caffeine
  • Excessive sweating without fluid replenishment

Mouth Breathing and Snoring

Mouth breathing while sleeping can result in dryness. This is more common with people who snore or have sleep apnea. This helps to relieve this condition by using a humidifier or by nasal breathing.

Medications

Xerostomia is a side effect of many different medications. Here are a few of the most common offenders:

  • Antihistamines
  • Antidepressants
  • Blood pressure medications
  • Diuretics
  • Muscle relaxants

If your medication makes your mouth dry, ask your doctor if this medication can be replaced.

Underlying Health Conditions

Dry Mouth Is associated with some medical conditions. These include:

Diabetes: Elevated blood sugar levels can cause dehydration and decreased saliva production.

Sjogren’s syndrome: A disorder that destroys the salivary glands.

Sleep Apnea: Mouth breathing during sleep is common among those with sleep apnea, resulting in dryness.

Smoking and Drinking

The use of tobacco and alcohol is a common cause of dry mouth. Smoking decreases saliva flow, and alcohol also dehydrates the body, increasing dryness.

Stress and Anxiety

Emotional stress will also impact salivation. Stressful situations can cause dry mouths for many people, which can carry into the night.

Aging

Aging is not itself a direct cause of xerostomia, but older adults are more likely to take medications or have medical conditions that cause dry mouth.

Home Remedies for Dry Mouth

If you regularly have a dry mouth, a home remedy can provide some relief. These natural remedies help promote saliva production and keep the mouth moist.

Stay Hydrated

One of the easiest dry-mouth home remedies is to drink enough water during the day. Try to:

  • Take small, frequent snippets of water, particularly before the mattress.
  • Avoid excess amounts of caffeine and alcohol. They can cause dehydration.

Use a Humidifier

A humidifier adds moisture to the air so your throat and mouth don’t dry out while you sleep. This can be especially helpful in the winter when indoor air can dry out.

Practice Nasal Breathing

Mouth breathing, one of the leading causes of dry mouth during the night, can be combated with some simple training and make a difference. You can:

  • Get some nasal strips to hold your nasal passages open.
  • If you have persistent congestion or sleep apnea, check with a doctor.

Chew Sugar-Free Gum or Have Sugar-Free Candy

Saliva production is stimulated by chewing, which assists with some of the causes of dry mouth. Instead, choose sugar-free gum or candies made from xylitol, which can also help prevent cavities.

Use Aloe Vera

Aloe vera is a natural moisturizer and can be a great dry-mouth home remedy. Drink aloe vera juice or use an aloe vera rinse to heal your mouth.

Use Coconut or Olive Oil Pulling

Oil pulling is an age-old practice that helps in keeping the mouth hydrated. Swishing a tablespoon of coconut or olive oil in your mouth for 10–15 minutes can help prevent dryness.

Refrain from Salty and Spicy Foods Before Bed

Salty and spicy foods can irritate the mouth and may worsen dehydration, which can aggravate dry mouth. Instead, eat hydrating foods like cucumbers, watermelon, and yogurt.

Try a Mouth Rinse for Dry Mouth

Over-the-counter mouth rinses made specifically for xerostomia usually include ingredients to help retain moisture. Seek out alcohol-free varieties that have xylitol or glycerin.

Increase Vitamin Intake

A lack of certain vitamins — including B12, iron, and zinc — can also be a causative factor in xerostomia. A diet rich in these nutrients, such as leafy greens, nuts, and fish.

Reduce Smoking and Alcohol

By cutting down on tobacco and alcohol consumption, saliva will greatly increase. If quitting is hard to do, look to the pros for quitting programs.

When to Seek Medical Help

Home solutions for dry mouth may help relieve the condition, but persistent xerostomia can indicate an underlying medical problem. In particular, contact a healthcare provider if you experience:

  • Trouble swallowing or speaking
  • Common sore throat or oral infections
  • Changes in taste perception
  • Cracked lips and mouth sores

A doctor can examine the causes of xerostomia and suggest medical treatments like saliva replacements, coveted prescription medications, or special therapies.

Significance of Salivary Dryness on the Oral Conditions

Chronic dry mouth doesn’t simply cause discomfort; it can also lead to major problems in your mouth. Saliva helps wash away food particles, neutralizes acids, and prevents the growth of bacteria. It’s not just because it’s mouth-drying, though; your mouth needs saliva to function properly — and if you’re not producing enough, here’s what could happen:

Higher Likelihood of Cavities: Saliva neutralizes acids and remineralizes enamel, hindering tooth decay. Reduced saliva production can speed up cavity formation.

Halitosis (Bad Breath): Bacteria can grow well in dry environments, causing bad breath.

Gum Disease: A dry mouth can lead to inflammation and raise the risk of both gingivitis and periodontitis.

Trouble with Swallowing and Speaking: Saliva helps with lubrication, which means you have an easier time swallowing food and enunciating speech.

However, if you suffer from dry mouth regularly, make sure to practice good oral hygiene and use dry mouth home remedies to protect your teeth and gums.

Foods and Drinks That Fight Causes of A Dry Mouth

Diet can help minimize dry mouth causes. Certain foods and drinks stimulate saliva production and keep your mouth hydrated:

Foods That Help

  • Crunchy fruits and vegetables (apples, celery, cucumbers) promote saliva flow and provide hydration.
  • Dairy (cheese, yogurt, milk) are high in calcium and phosphates and help strengthen teeth and stimulate saliva.
  • Nuts and seeds (almonds, flaxseeds, walnuts) keep mouth moist.
  • Hydrating Drinks help keep the mouth moist.
  • Herbal teas (chamomile, ginger, green tea) are soothing and facilitate saliva production.
  • Fresh coconut water is a refreshing and hydrating natural electrolyte beverage.

Conclusion

A dry mouth is more than annoying; it can affect oral health, digestion, and overall wellness. Knowing the causes of dry mouth at night and the effective home remedies for dry mouth can make a big difference.

Lifestyle modifications such as hydration, nasal breathing, humidifiers, and natural remedies such as aloe vera and oil pulling can effectively address dry mouth causes. It brings comfort to your nighttime routine again.

It is also advisable to try home remedies for dry mouth. That said, it’s still important to get medical advice if symptoms don’t go away because they can be a sign of underlying health conditions. Identifying the causes of dry mouth in your dentist's office sooner rather than later will help prevent complications and ensure oral health.

With the right approach, you can wake up feeling fresh — and without the tell-tale dry mouth!
