Dry mouth during sleep, also known as nocturnal xerostomia, impacts roughly one in five adults. Its causes vary widely, from mouth breathing to dehydration, and it can seriously damage sleep quality. In this article, we’ll explore the products that aim to prevent dry mouth, from sprays and gels to dental guards like MouthShield, which takes a safer, smarter approach to nighttime hydration.
Product Solutions to Prevent Dry Mouth During Sleep
Many over-the-counter products claim to prevent dry mouth, but not all of them are equally effective. Some may offer only temporary relief.
Here, we’ll review the most popular options, digging into what makes each work, where they might fall short, and which products could give you the uninterrupted, restful sleep you’re after.
Dental Guards: The Best Alternative
Dental guards can offer the most comprehensive solution to managing dry mouth. Unlike other products that offer only temporary relief or come with significant drawbacks, they’re designed for lasting support throughout the night. They promote a balanced approach that doesn’t rely on sticky adhesives or artificial humidification, making them a more sustainable solution.
Dental guards work by gently encouraging nasal breathing while keeping the mouth comfortably closed, all without the risks of tape. This directly addresses one of the leading causes of dry mouth, open-mouth breathing, not only supporting oral moisture but also encouraging healthier breathing patterns over time.
With dental guards, users benefit from consistent support that improves sleep quality without disrupting natural breathing. Unlike mouth taping, which seals the lips completely and blocks airflow, these guards keep your airway open, allowing for easy, unobstructed breathing through the nose. This promotes natural breathing without the risk of suffocation or discomfort, making for a safer option for people with nasal congestion or sleep apnea.
For those with chronic dry mouth due to mouth breathing, the impact of a well-fitted dental guard can be huge, improving hydration and comfort all the way to the morning.
The Best Dental Guard: MouthShield
Among the many dental guards out there, Mouth Shield is a trusty pick. It’s loved by users and professionals alike for its comfort and ability to support hydrated, uninterrupted sleep. Safe, non-invasive, and adaptable for a wider range of users, it combines the benefits of a quality mouth guard with innovative features that make it both effective and user-friendly.
Mouth Shield is designed to fit snugly between your lips and teeth, gently encouraging the mouth to remain closed throughout the night to support nasal breathing. Crafted from 100% medical-grade silicone, it seamlessly conforms to your mouth while maintaining its shape, and its soft, rounded edges provide a smooth feel against your gums and cheeks. This makes it perfect for those who are sensitive to adhesives or need a solution they can use consistently without discomfort.
Mouth Shield is also trimmable for a custom, comfortable fit for a mouth of any size. Designed for repeated use, it’s durable and reusable, making it a less wasteful, more cost-effective choice compared to disposable products like mouth sprays or tape. Plus, it’s easy to clean, so things stay hygienic with little-to-no upkeep.
For those seeking a sustainable, nightly solution to dry mouth, Mouth Shield is a reliable option, combining safety, convenience, and proven results for more refreshing and comfortable sleep.
Nasal Breathing Products: Are They Enough?
Nasal breathing products like nose strips and dilators are designed to keep the nasal passages open, promoting nasal breathing over mouth breathing while you sleep. This method is often recommended for people who often wake up with a dry mouth due to habitual mouth breathing. By keeping the mouth closed and improving nasal airflow, these products encourage more natural, hydrating nasal respiration instead of mouth breathing, which quickly dries out your oral cavity.
However, nasal breathing products aren’t always a one-size-fits-all solution.
If you’re experiencing dry mouth due to medication, dehydration, or other non-respiratory causes, these aids may fall short. They can’t address underlying issues related to reduced saliva production, such as those caused by antihistamines or other medications. While they may improve sleep quality for some, their ability to fully prevent dry mouth is often limited.
Humidifiers: Limited Benefits for Dry Mouth
Humidifiers are pretty straightforward. They work by adding moisture to your environment, so the air you breathe in during sleep is less dry. The added humidity can be helpful for people dealing with mild cases of dry mouth, particularly in arid climates or during the winter, when use of indoor heating can strip the air of moisture. Breathing in more humid air can reduce dry mouth symptoms.
That said, humidifiers aren’t a panacea. They don’t address dry mouth caused by medication, open-mouth sleeping, or other health conditions. Plus, these devices require frequent cleaning to prevent mold and bacteria growth, which adds a layer of upkeep that might not be ideal for everyone. So while humidifiers can help alleviate mild dry mouth, they’re often just one part of a larger solution.
Mouth Sprays and Gels: Quick but Temporary Relief
Mouth sprays and gels are often marketed as quick fixes for dry mouth.
They provide immediate moisture with ingredients designed to lubricate and coat the inside of your mouth. These products are particularly useful for people with dry mouth caused by reduced saliva production, such as those on medications with side effects. Some sprays also contain xylitol—an ingredient you might recognize from sugar-free chewing gums—which can stimulate saliva production and reduce bacterial buildup in the mouth.
While these sprays and gels may offer short-term relief, their effects don’t last long. Most of them need to be reapplied throughout the night, so you’re still waking up and sacrificing sleep quality. Plus, some users report that these products leave an unpleasant taste or mild irritation after extended use, so they’re unlikely to provide lasting comfort through the night.
Mouth Taping: Risks and Limited Impact
Mouth taping is a controversial practice that has gained popularity on social media. It involves sealing your lips shut with adhesive tape to keep your mouth closed during sleep. The idea behind mouth taping is to force nasal breathing, which can help reduce snoring and prevent dry mouth.
This might seem like a straightforward solution, but experts urge caution.
According to research published in JAMA Otolaryngology, mouth taping can restrict airflow, especially for people who suffer from sleep apnea or nasal congestion. When nasal passages become blocked at night, things can get dangerous. Forcing the mouth shut without proper nasal airflow increases the risk of oxygen deprivation, leading to frequent waking, disturbed sleep, or in extreme cases, respiratory distress.
Plus, using adhesive products around the mouth can lead to skin irritation and discomfort, and the claustrophobic feeling of a taped mouth can make people anxious. And, like nasal breathing products, mouth taping doesn’t quite address dry mouth caused by dehydration, medications, or other underlying factors, so its impact on dry mouth is often limited.
