Unraveling the Mysteries of Closed-Mouth Snoring and Finding Restful Solutions

Last updated: August 16th, 2023


Overview of Snoring

Snoring is a common phenomenon experienced by many individuals worldwide, and it has, over time, become an oft-joked about nightly nuisance in households. But beyond the nighttime symphony it creates, snoring is essentially the sound produced by the vibration of respiratory structures due to obstructed air movement during breathing.

This obstruction can be caused by a range of factors. From a relaxed throat leading to narrowing of the airway to a deviated septum in the nose, the reasons people snore are varied. While many consider it a mere inconvenience or a reason for chuckles, chronic snoring can indicate a more severe health condition, like obstructive sleep apnea, which can lead to other health complications if not addressed.

Differentiation Between Mouth-Open and Mouth-Closed Snoring

Distinguishing between the two primary types of snoring—mouth-open and mouth-closed—is essential for understanding the underlying cause and identifying potential treatments.

  1. Mouth-Open Snoring: This type of snoring often indicates issues with the tissues in your throat. When we sleep, our muscles relax, including those in the throat. For some, this relaxation can cause the throat to constrict slightly, leading to an obstruction. With the mouth open, the airflow becomes more turbulent, vibrating the surrounding tissues (like the uvula and the soft palate), thus producing the snoring sound.

  2. Mouth-Closed Snoring: If someone snores with their mouth closed, it might indicate a problem rooted deeper in the airway or related to the tongue. One common reason is the tongue dropping to the back of the mouth, obstructing the air passage. Additionally, nasal obstructions due to conditions like a deviated septum or nasal polyps can lead to snoring even with the mouth firmly shut. This type of snoring might suggest that the individual has issues with their nasal airways or possibly an underlying issue with tongue positioning.

Recognizing the difference between these two types of snoring is crucial. Not only does it give a hint toward the root cause, but it also guides the pathway to potential remedies, some of which might be simple lifestyle changes while others could require medical intervention.

In the upcoming sections, we will delve deeper into the intricacies of mouth-closed snoring, exploring its primary causes, the implications on an individual's health, and possible remedies to ensure a quiet, restful night's sleep.

Understanding Closed Mouth Snoring

Definition and Distinct Features of Closed-Mouth Snoring

Closed-mouth snoring, as the name implies, occurs when an individual snores while having their mouth fully or mostly shut. This type of snoring is distinctive, as it often emits a different sound quality compared to mouth-open snoring. It tends to have a nasal quality due to the airflow being primarily restricted to the nasal passages.

Here are some of the distinct features of closed-mouth snoring:

  1. Nasal Sound Quality: Closed-mouth snoring often has a muffled or nasal tone, which can be softer or sometimes even more piercing than mouth-open snoring.
  2. Consistency: While this isn't true for everyone, some individuals who snore with their mouth closed might have a more rhythmic and consistent snoring pattern, as it is majorly affected by the nasal airflow.
  3. Positional Influence: This type of snoring can be influenced by sleeping positions, with some noticing an increase in its intensity when lying on their back, while others might experience it more prominently on their side.

Why Do Some People Snore with Their Mouth Closed?

Understanding the phenomenon requires diving into the anatomy and physiology of our respiratory structures. Here are the leading reasons:

  1. Nasal Obstruction: One of the primary reasons for closed-mouth snoring is nasal obstruction. This obstruction can be due to various reasons - a deviated septum (misalignment of the wall that divides the two nostrils), nasal polyps (non-cancerous growths in the lining of the nasal passage), or even allergies causing swollen turbinates.

  2. Tongue Positioning: During sleep, muscle relaxation throughout the body is natural. However, in some individuals, the tongue might fall back towards the throat, causing a partial airway blockage. This obstruction can lead to the vibration of tissues, causing the snoring sound.

  3. Retrognathia or Micrognathia: These are conditions where the lower jaw is set further back than the upper jaw (retrognathia) or is unusually small (micrognathia). These jaw positions can push the tongue back towards the throat, leading to an obstruction and consequently, snoring.

  4. Palatal Stiffness: The roof of the mouth or the hard palate might have increased stiffness in some individuals. This stiffness can cause vibration during the airflow, leading to snoring.

  5. Throat Tissue Excess: While this often contributes more to open-mouth snoring, in some cases, individuals with excess throat tissue or enlarged tonsils might still produce snoring sounds even with their mouths closed due to slight vibrations.

  6. Other Factors: Lifestyle factors such as alcohol consumption, obesity, and certain medications can relax the muscles of the throat and tongue more than usual, leading to increased chances of closed-mouth snoring.

Primary Causes of Closed Mouth Snoring

Understanding the reasons behind closed mouth snoring can pave the way for effective remedies and ensure a better quality of sleep. Let's delve into the primary causes:

1. Deviated Septum and Wide Nose: The Connection

The nasal septum is the thin wall between your nostrils that separates your left and right nasal passages. Ideally, the septum should run down the center of your nose. However, if it leans to one side or the other, it's referred to as a deviated septum. A deviated septum can restrict or block one of the nasal passages, causing airflow restriction.

A wide nose or broad nasal passages can also contribute to this problem. While a wide nose can sometimes allow for more air intake, the internal structures, if not aligned properly, might lead to disturbances in airflow, leading to vibrations that manifest as snoring.

2. Sleep Apnea: Its Role in Snoring with a Closed Mouth

Obstructive sleep apnea (OSA) is a medical condition where an individual's airway becomes blocked during sleep, either entirely or in part. This blockage often results in breathing cessation for a few seconds to even minutes. Snoring, especially with a closed mouth, can be a symptom of OSA.

The periodic blocking and unblocking of the airway lead to variations in the snoring pattern. Often, the snoring is loud, followed by a period of silence (apnea event) and then a gasp or snorting sound as the person starts breathing again.

3. Throat Snoring: How Does It Contribute?

Throat snoring, or pharyngeal snoring, is primarily due to the vibration of the soft tissues at the back of the throat, including the soft palate and uvula. Factors like excessive fatty tissues, enlarged tonsils, or loss of muscle tone can cause the throat's airspace to narrow. Even with the mouth closed, if there's a significant restriction in the throat, the airflow will cause these tissues to vibrate, producing the typical snoring sound.

4. Nasal and Throat Obstructions

Apart from the deviated septum, other obstructions can cause snoring. Nasal polyps, swollen turbinates due to allergies, or chronic congestion can restrict airflow. Similarly, obstructions in the throat, such as enlarged tonsils, adenoids, or excessive fatty tissue, especially in individuals who are overweight, can contribute to snoring.

5. Positional Factors: Snoring When Flat on the Back, on the Side, and Other Positions

Your sleeping position has a direct impact on your airway's alignment and can influence the intensity and frequency of snoring.

  • Flat on the Back: This position is notorious for promoting snoring. Gravity acts on the relaxed muscles of the tongue and throat, causing them to fall backward and obstruct the airway. For those predisposed to snoring, lying flat on their back can exacerbate the problem.

  • On the Side: Side sleeping is often recommended to reduce snoring because it prevents the tongue and soft palate from collapsing into the back of the throat. However, some people might still snore on their side due to other factors like nasal obstructions.

  • Other Positions: Positions like the fetal position or stomach sleeping can influence snoring patterns based on how they affect neck alignment and pressure on the airways.

Factors Affecting the Intensity of Closed Mouth Snoring

While snoring is common, the intensity and nature of snoring sounds can vary greatly from person to person. Closed mouth snoring, in particular, can range from a soft, almost musical hum to an intense, room-filling cacophony. Understanding the factors affecting its intensity can provide insights into the root cause and potential solutions.

1. What Leads to Loud Snoring?

Several factors can amplify the volume of a person's snoring:

  • Degree of Obstruction: The greater the airway obstruction, the harder the body has to work to push air through, which increases the velocity of airflow and thus the vibration of tissues. This results in louder snoring sounds.

  • Tissue Laxity: Over-relaxed or floppy tissues in the mouth and throat, often due to factors like alcohol consumption or certain medications, can vibrate more intensely, producing louder snores.

  • Throat Anatomy: A person's anatomy can naturally predispose them to louder snoring. Those with a longer soft palate or uvula, enlarged tonsils, or extra fatty tissue in the throat can produce more intense sounds.

  • Body Weight: Excess weight, especially around the neck, can exert added pressure on the airway, causing it to narrow. The increased tissue mass can lead to more pronounced vibration and consequently louder snoring.

2. The Implications of Snoring on Exhale

Most people snore more prominently during inhalation, but snoring on exhale, while less common, is not unheard of. This reversed pattern can be indicative of several things:

  • Blockage at Base of Tongue: The tongue's position can lead to an obstruction during exhalation. It might be more prone to block air when air is being pushed out rather than sucked in.

  • Sleep Apnea Consideration: Exhale snoring might also be associated with types of sleep apnea. With each apnea event (a pause in breathing), the person might snore or gasp upon exhalation as they struggle to push out carbon dioxide and take in oxygen.

  • Relaxed Throat Muscles: Overly relaxed muscles, again due to alcohol or certain medications, might collapse more prominently when one exhales, causing snoring.

3. What Does it Mean When Someone Starts Snoring with Mouth Closed?

If someone who typically doesn't snore starts to snore with their mouth closed, it might indicate a few things:

  • Nasal Congestion or Obstruction: The person might be experiencing some form of nasal congestion due to allergies, colds, or other factors that make nasal breathing challenging.

  • Changes in Sleep Position: If they've recently shifted to sleeping on their back, it might lead to tongue and throat muscle relaxation that prompts closed-mouth snoring.

  • Lifestyle Factors: Weight gain, increased alcohol consumption, or starting a new medication can all be contributing factors.

  • Progression of an Underlying Condition: The onset of conditions like sleep apnea might manifest as a sudden start to snoring.

  • Aging: As we age, the muscle tone in our throat decreases, potentially leading to snoring even if one has never snored before.

Special Cases and Observations

The phenomenon of closed mouth snoring, while widely observed in adults, has unique presentations across different groups and settings. Diving into special cases and anecdotal observations can shed light on this multifaceted issue.

1. Toddler Snoring with Mouth Closed: Is it Different from Adults?

Toddlers, given their still-developing anatomy and respiratory systems, exhibit different snoring characteristics than adults:

  • Nasal Obstructions: Young children, especially toddlers, have narrower nasal passages. Even minor obstructions such as colds or allergies can cause noticeable snoring.

  • Adenoids and Tonsils: The adenoids (lymph tissue in the back of the nose) and tonsils can be relatively larger in toddlers, leading to potential airway obstructions when they sleep.

  • Sleep Patterns: Children have different sleep cycles and patterns, often spending more time in deep sleep where muscle relaxation is profound, potentially leading to snoring.

  • Concerns: While occasional snoring might not be a cause for concern, consistent snoring in toddlers can be indicative of sleep disorders, breathing issues, or even sleep apnea. It's essential to consult a pediatrician in such cases.

2. Observations from the Reddit Community on Closed Mouth Snoring

Online communities, like Reddit, provide a platform for individuals to share personal experiences, seek advice, and offer solutions. Here are some general observations regarding closed mouth snoring:

  • Varied Experiences: Some users report sudden onset snoring due to factors like weight gain, while others discuss it as a lifelong issue.

  • Remedies and Solutions: From using nasal strips, anti-snoring devices, to side-sleeping techniques, many anecdotal solutions are shared and discussed.

  • Seeking Medical Advice: A common thread involves users advising others to seek professional medical advice, especially when symptoms could indicate sleep apnea.

3. Closed Mouth Snoring and CPAP: The Relationship

Continuous Positive Airway Pressure (CPAP) machines are designed to help people with sleep apnea. By delivering a continuous stream of air, these machines keep the airways open, reducing or eliminating snoring.

  • Effectiveness: For many with closed mouth snoring due to sleep apnea, a CPAP machine can be a game-changer, significantly reducing or even eliminating their snoring.

  • Adaptation: Some users might find snoring reduced but not entirely eliminated as they adjust to using a CPAP. Over time, with proper mask fit and pressure settings, snoring often decreases.

4. Snoring with a Closed Mouth Even with an APAP Machine: What to Do?

APAP (Automatic Positive Airway Pressure) machines adjust the air pressure automatically based on the user's needs, unlike CPAP which delivers a constant pressure.

  • Check Machine Settings: Ensure that the machine's settings are adjusted correctly and that it's functioning as intended.

  • Mask Fit: A poor-fitting mask can lead to air leaks, reducing the machine's effectiveness. Ensure a snug fit and consider trying different mask styles if necessary.

  • Consult a Sleep Specialist: If snoring persists even with an APAP, it's crucial to revisit a sleep specialist. They can re-evaluate the situation, potentially recommending a sleep study or adjusting the machine's settings.

  • Consider Other Factors: Snoring might not solely be due to sleep apnea. If an APAP doesn't alleviate it, other factors like nasal obstructions, body weight, or even sleeping position might be contributing.

Remedies and Treatments

Closed mouth snoring can be disruptive, not just for the individual, but also for those sharing their sleeping environment.

Fortunately, a range of remedies and treatments (including natural and herbal remedies) are available to address this issue, depending on its root cause and severity.

1. Home Remedies to Stop Closed Mouth Snoring

  • Elevate the Head: Using an extra pillow or a wedge can help to elevate the head, reducing the gravitational pull on the soft palate and tongue, thus preventing airway obstruction.

  • Maintain a Healthy Weight: Weight loss, especially reducing fatty tissue around the neck, can help in decreasing or eliminating snoring.

  • Stay Hydrated: A well-hydrated throat is less sticky and less prone to produce snoring sounds.

  • Avoid Alcohol Before Bed: Alcohol relaxes the muscles of the throat, making snoring more likely. It's advisable to avoid alcohol consumption at least 2 hours before bedtime.

2. Over-the-Counter Solutions: Anti-Snoring Mouthpieces and Their Effectiveness

  • How They Work: Anti-snoring mouthpieces typically work by moving the lower jaw and tongue forward, increasing the space in the airway and reducing airway obstruction.

  • Effectiveness: These devices can be effective for many individuals, especially for those whose snoring is the result of tongue or jaw position. However, their efficacy can vary, and it's important to find one that's comfortable and suitable for individual needs.

  • Customization: While generic versions are available, some individuals opt for custom-made devices from dental specialists for improved fit and comfort.

3. Surgical and Medical Interventions: Treating Deviated Septum and Other Obstructions

  • Nasal Surgeries: Procedures like septoplasty can correct a deviated septum, improving airflow and potentially reducing or eliminating snoring.

  • Uvulopalatopharyngoplasty (UPPP): This surgical procedure removes excess tissue from the throat, enlarging the airway. This can reduce the vibrations that cause snoring.

  • Tonsillectomy or Adenoidectomy: For those with enlarged tonsils or adenoids obstructing the airway, their removal might alleviate snoring.

4. Positive Airway Pressure Devices: CPAP and APAP for Snoring

  • How They Work: Both CPAP (Continuous Positive Airway Pressure) and APAP (Automatic Positive Airway Pressure) machines work by delivering a continuous or variable stream of air, keeping the airway open and preventing snoring.

  • Selection and Use: A sleep study, often recommended by a sleep specialist, can determine the right type and settings for these devices.

  • Maintenance: Regular cleaning and maintenance of these devices, as well as ensuring a proper mask fit, are crucial for their effectiveness.

5. Positional Therapy: Adjusting Sleep Positions for Better Airflow

  • Side Sleeping: Many people find that they snore less when sleeping on their side compared to their back. Using a body pillow can help maintain this position throughout the night.

  • Adjustable Beds: Beds that allow for elevation at the head can mimic the effect of using extra pillows, facilitating better airflow.

  • Positional Devices: Some wearable devices can detect when a person is sleeping on their back and vibrate to prompt them to change positions, thereby potentially reducing snoring.

Conclusion and Further Recommendations

Addressing closed-mouth snoring requires a deep understanding and a multi-faceted approach. As we've delved into the myriad of causes, implications, and remedies, it becomes evident that snoring is not just a nocturnal disturbance, but often a manifestation of underlying health conditions or physical anomalies.

1. Sleeping with the Mouth Closed: Does it Prevent Snoring?

Contrary to popular belief, merely keeping one's mouth shut doesn't guarantee a snore-free night. While open-mouth snoring is often linked to issues like sleep posture or congestion, closed-mouth snoring tends to be more deeply rooted, related to obstructions or issues in the nasal passages or throat. As such, the answer is nuanced: while sleeping with a closed mouth might reduce the risk of snoring for some, it isn't a one-size-fits-all solution.

2. Encouraging a Holistic Approach to Managing and Treating Snoring

While remedies and treatments abound, it's crucial to approach snoring from a holistic perspective:

  • Lifestyle Adjustments: Simple changes, such as weight management, reduced alcohol consumption, or altering sleep position, can make a significant difference for many individuals.

  • Medical Consultations: A sleep study or consultation with a sleep specialist can be invaluable in pinpointing the exact cause of snoring and recommending the most effective treatment.

  • Continuous Monitoring: It's important to monitor any changes in snoring patterns, frequency, or intensity. Such changes can indicate evolving health conditions or the effectiveness (or lack thereof) of a chosen remedy.

3. Tips for Partners and Roommates of Snorers

Living with a snorer can be challenging. For those on the receiving end:

  • Earplugs: A simple yet effective solution, earplugs can drastically reduce the noise level and promote better sleep.

  • White Noise Machines: These devices can mask the sound of snoring, providing a consistent ambient noise that many find soothing.

  • Communication: It's crucial to communicate feelings and concerns without blaming the snorer, who may already feel self-conscious or guilty about the issue.

  • Encourage Treatment: Encourage the snorer to seek treatment, emphasizing that it's not just about noise reduction, but often about improving their health and well-being.

In wrapping up, while closed-mouth snoring can be perplexing, solutions and treatments are at hand. With the right approach, informed by understanding and compassion, both snorers and their loved ones can find relief and restful nights.

FAQs on Snoring and Mouth Position

  1. Will I stop snoring if I close my mouth?

    • Not necessarily. While some people may snore due to an open mouth, others snore with their mouths closed due to nasal or throat obstructions. Closing your mouth might reduce the risk of snoring for some individuals, but it's not a guaranteed solution for everyone.
  2. Should mouth be open or closed for snoring?

    • The position of the mouth—whether open or closed—relates more to the cause of the snoring than a preferred state. Some individuals snore when their mouth is open because of the relaxed position of the tongue or jaw. Others snore with a closed mouth due to issues within the nasal passages or throat. It's essential to determine the root cause of snoring to address it effectively.
  3. Why do I sleep with my mouth open but don't snore?

    • Sleeping with an open mouth doesn't automatically lead to snoring. It might be a natural position for you, or perhaps due to nasal congestion that makes breathing through the nose more difficult. As long as you're breathing comfortably and not experiencing any disruptions in sleep, an open mouth in itself isn't a concern.
  4. How do you fix a snoring palate?

    • A snoring palate refers to the vibrations of the soft palate during breathing, which can lead to snoring sounds. Solutions can range from lifestyle changes (like side sleeping or weight loss) to using devices like anti-snoring mouthpieces that reposition the tongue and jaw. In more severe cases, surgical interventions such as Uvulopalatopharyngoplasty (UPPP) might be recommended to remove or reshape parts of the soft palate. Consulting with a sleep specialist or ENT doctor is essential to determine the best approach for your situation.
