What is Mouth Taping and Why Should You Care?

Mouth taping, as the name implies, involves placing a strip of tape over your lips before you go to sleep. Sounds strange, right? Despite its unusual premise, this practice has been gaining attention for its potential health benefits. But before we dive into these benefits, let's discuss why someone might need to tape their mouth in the first place.

Humans are designed to breathe through their noses, especially during sleep. This is because nasal breathing has a multitude of advantages over mouth breathing. Nasal breathing warms and humidifies the air, filters out particles and pathogens, increases the intake of nitric oxide (a potent vasodilator that can enhance oxygen uptake), and maintains optimal CO2/O2 balance in our blood.

Unfortunately, a variety of factors such as allergies, nasal congestion, or certain habits, may cause some people to breathe through their mouths, especially while sleeping. This is where mouth taping comes into play. It gently encourages the body to breathe through the nose, restoring the natural breathing pattern.

Unravelling the Benefits of Mouth Taping

Mouth Taping for Sleep

A primary benefit of mouth taping is improved sleep quality. Nasal breathing promotes a slower and deeper breathing pattern, which can improve sleep efficiency and reduce instances of snoring and sleep apnea. You can also visit the British Sleep Society to learn more about improving your sleep. 

Mouth Taping for Snoring 

Mouth taping can be a particularly helpful practice for individuals who snore due to mouth breathing. Snoring often occurs when air flows past relaxed tissues in your throat, causing the tissues to vibrate as you breathe, which creates the familiar snoring sound. By keeping the mouth closed and promoting nasal breathing, mouth taping can significantly reduce, or even eliminate, snoring in some people.

Mouth Taping for Sleep Apnea

Sleep apnea is a serious sleep disorder where breathing repeatedly stops and starts. One form of this condition, obstructive sleep apnea, can be exacerbated by mouth breathing. When you breathe through your mouth during sleep, your tongue can fall back into your throat, obstructing the airway and leading to the interruptions in breathing that characterise sleep apnea.

Mouth taping can help address this issue by promoting nasal breathing, which can potentially reduce the occurrences of apnea events. However, it's crucial to note that mouth taping is not a cure for sleep apnea. If you suspect you have sleep apnea, you should seek medical advice immediately. The condition can lead to a variety of health problems if left untreated.

Mouth Taping, Deviated Septum, and Nasal Obstruction

Even for those with a deviated septum or nasal obstruction, mouth taping can still be beneficial. While it may not directly correct these conditions, it can foster better breathing habits and reduce the impact of these issues on overall health and sleep quality.

Mouth Taping for Gum Disease and Oral Health

When we breathe through our mouths, we're more likely to experience dry mouth because the continuous flow of air can evaporate the saliva more quickly. This state of dryness can create an environment that is more conducive to the growth of harmful bacteria, leading to an increased risk of oral health issues, including gum disease.

Gum disease, or periodontal disease, is an infection of the tissues that hold your teeth in place. It's typically caused by poor brushing and flossing habits that allow plaque—a sticky film of bacteria—to build up on the teeth and harden. In advanced stages, periodontal disease can lead to sore, bleeding gums, painful chewing problems, and even tooth loss.

Mouth taping can help to mitigate this risk by encouraging nasal breathing, thereby reducing the likelihood of dry mouth and helping to maintain a healthier oral environment. This, along with good oral hygiene practices, can significantly reduce the risk of gum disease. Visit the British Dental Association's website for more information on gum disease. 

Mouth Taping and Blood Pressure

While the relationship between mouth taping and blood pressure isn't as direct as some of the other topics we've discussed, there is indeed a connection that can be traced back to the way we breathe.

When you breathe through your nose, your body is able to produce more nitric oxide, a potent molecule that plays a key role in vasodilation, which is the widening of blood vessels. By promoting blood vessel relaxation, nitric oxide can help lower blood pressure by allowing blood to flow more freely throughout the body.

Moreover, nasal breathing is more conducive to activating the parasympathetic nervous system, which is responsible for the body's 'rest and digest' responses. This system helps to slow the heart rate and decrease blood pressure, among other functions. Mouth breathing, on the other hand, tends to activate the sympathetic nervous system, which is involved in the 'fight or flight' responses and can lead to increased heart rate and blood pressure.

By promoting nasal breathing, mouth taping might indirectly help support better blood pressure regulation. It's important to note, however, that the effects are likely to be minor and should not be considered a primary treatment for high blood pressure. If you're struggling with high blood pressure, it's crucial to consult with a healthcare professional to discuss appropriate interventions, which may include lifestyle changes, medication, or other treatments. Mouth taping can be considered a supportive practice as part of a broader health optimisation strategy.

Boosting Your Immune System with Mouth Taping

By improving sleep quality and supporting respiratory health, mouth taping might indirectly support the immune system. However, it's not a standalone solution and should be combined with a healthy lifestyle for comprehensive health optimisation. Here are some ways mouth taping can support your immune system:

• Improved Sleep Quality: As we've already discussed, mouth taping can improve sleep quality by reducing snoring and instances of sleep apnea. The relationship between sleep and the immune system is well-documented: getting adequate, high-quality sleep can boost your immune function, while sleep deprivation can weaken it. In this way, mouth taping could indirectly support the immune system by promoting better sleep.
• Nasal Breathing Benefits: When we breathe through our noses, the air we inhale gets filtered, warmed, and humidified before it reaches the lungs. This process not only makes the air more suitable for the delicate tissues in the lungs, but it also helps to trap and remove pathogens (disease-causing microbes) from the air, acting as a first line of defence against respiratory infections. By encouraging nasal breathing, mouth taping can support these natural defence mechanisms, potentially bolstering respiratory health and immunity.
• Oral Health and Immunity: As we've mentioned before, mouth taping can help prevent dry mouth, which in turn can reduce the risk of oral health problems like gum disease and tooth decay. The immune system plays a key role in protecting against these conditions, so maintaining good oral health can free up immune resources to be used elsewhere in the body.

Before and After: The Impacts of Mouth Taping on Your Life

Mouth breathing, while sometimes necessary due to certain health conditions or temporary issues like nasal congestion, can lead to a variety of challenges when it becomes a chronic habit. Here's a comparison of what life might look like before and after correcting mouth breathing with strategies like mouth taping:

Before Correcting Mouth Breathing

• Poor Sleep Quality: Chronic mouth breathers often experience disrupted sleep. They may snore loudly and suffer from conditions like sleep apnea, which can cause repeated awakenings throughout the night, leading to poor sleep quality.
• Oral Health Problems: Mouth breathing can dry out the oral cavity, which can lead to issues like bad breath, cavities, and gum disease.
• Respiratory Issues: Mouth breathing bypasses the nose's natural filtration system for airborne particles and pathogens, potentially increasing the risk of respiratory infections.
• Facial Development Issues in Children: In children, chronic mouth breathing can potentially impact facial and dental development, leading to issues like long, narrow faces, gummy smiles, and bite problems.
• Increased Blood Pressure: Chronic mouth breathing can cause you to take more shallow breaths, leading to lower oxygen levels in the body, which may result in increased blood pressure and heart rate.

After Correcting Mouth Breathing:

• Improved Sleep Quality: Nasal breathing promotes better sleep quality by reducing snoring and the risk of sleep apnea. This can lead to feeling more rested and energised during the day.
• Better Oral Health: Nasal breathing allows the mouth to maintain its natural moisture balance, which can help to prevent oral health problems like cavities and gum disease.
• Reduced Risk of Respiratory Infections: Breathing through the nose allows the air to be filtered, warmed, and humidified, which can reduce the risk of respiratory infections.
• Better Physical Performance: Nasal breathing helps to maintain optimal CO2/O2 balance in the blood and enhance nitric oxide production, which can improve overall physical performance and recovery.
• Normalised Blood Pressure: The switch to nasal breathing can lead to more efficient oxygen-CO2 exchange, which may have a positive effect on blood pressure and heart rate.

Changing Facial Structure

Chronic mouth breathing, particularly during childhood and adolescence when the bones of the face are still developing, can indeed affect facial structure. The body adapts to the way it is used, and this includes the structures involved in breathing.

Before Correcting Mouth Breathing:

• Long, Narrow Faces: Chronic mouth breathing can lead to the development of a long, narrow face, sometimes referred to as "adenoid facies" or "long face syndrome." This occurs because the mouth is continually open, causing the face to grow downwards rather than widthwise.
• Altered Dental Structure: Mouth breathers might also develop a high, narrow palate and experience alterations in their bite (the way the upper and lower teeth come together). This can include an overbite, where the upper front teeth overlap the lower front teeth to a greater degree than normal, or an open bite, where the front teeth, both upper and lower, slant outward and do not touch even when the mouth is fully closed.
• Gummy Smile: Some mouth breathers may develop what's known as a 'gummy smile,' where an excessive amount of gum tissue shows above the top teeth when smiling.

After Correcting Mouth Breathing:

• Normal Facial Growth: By switching to nasal breathing, the mouth can remain closed more often, potentially allowing the bones of the face to develop more naturally. This can contribute to a more balanced facial structure.
• Improved Dental Alignment: With nasal breathing, the tongue rests on the roof of the mouth, providing a natural brace that helps shape the palate and supports proper alignment of teeth. This can help prevent some of the dental issues associated with mouth breathing.
• Less Gummy Smile: A shift from mouth to nasal breathing may also reduce the likelihood of developing a 'gummy smile,' as the facial muscles and oral structures are able to develop more naturally.

It's important to note that these changes are not instant and may take time. In some cases, especially where mouth breathing has significantly influenced facial and dental development, professional interventions such as orthodontics or orthotropic treatment may be necessary. It's always advisable to consult a healthcare professional for personalised advice.

Is Mouth Taping Dangerous? Ensuring Safety While Reaping the Benefits

While mouth taping can offer numerous health benefits, it's crucial to ensure safety when practising it. Understanding the correct methods of application, acknowledging when to avoid it (e.g., during a respiratory infection), and knowing who should not use it (e.g., children without professional guidance) is key to reducing the potential risks associated with mouth taping.

Conclusion

Mouth taping offers a simple and cost-effective strategy to improve sleep quality, enhance oral health, and boost overall well-being. However, like all health interventions, it's important to practise it correctly and safely. Always consult a healthcare professional if you have any doubts or questions. By doing so, you can enjoy the myriad benefits of mouth taping while ensuring your health and safety.
