The best tape for mouth taping is a hypoallergenic, medical-grade tape with a silicone-based adhesive. This type is gentle enough to wear on facial skin overnight without causing irritation, and it peels off in the morning without stripping skin or leaving sticky residue. You have two main routes: purpose-built mouth tape strips or standard surgical tape from the pharmacy.
Medical Surgical Tape
3M Micropore tape is the most popular drugstore option. It was originally designed for wound care, is hypoallergenic and breathable, and costs just a few dollars per roll. You cut a small strip to size and place it vertically over your lips. The downsides: it’s not shaped for your mouth, the adhesive can weaken overnight if you drool, and removing it can tug at lip skin if you’re not careful.
Micropore and most standard surgical tapes use acrylate-based adhesives. These work fine for most people, but research comparing adhesive types on facial skin found that silicone-based adhesives caused less skin injury and higher patient satisfaction than standard acrylate tapes. If you notice redness, peeling, or irritation after using surgical tape, a silicone adhesive product is worth trying.
Purpose-Built Mouth Tape Strips
Several brands now make strips specifically shaped for the mouth. The main advantage over cut-your-own surgical tape is convenience and design features like breathing vents, contoured shapes, and adhesives formulated for lip and facial skin. Here’s how the popular options differ:
- SomniFix: Includes a central breathing vent so a small amount of air can pass through if needed. Uses a hypoallergenic adhesive marketed for sensitive skin.
- MyoTape: Uses a patented design that wraps around the lips rather than covering them directly. It gently encourages mouth closure without sealing the mouth shut, and allows “mouth puffing” and emergency opening. Also has a breathing vent.
- VIO2: Made with medical-grade adhesive, cotton, and spandex. Features a breathing vent.
- Dream Recovery: Made from organic bamboo silk with a medical-grade hypoallergenic adhesive. Designed to stay on all night without leaving residue.
Purpose-built strips typically cost between $15 and $25 for a month’s supply. If you’re just testing whether mouth taping works for you, starting with a roll of Micropore tape is the cheapest way to experiment before committing to a subscription product.
Silicone vs. Acrylate Adhesives
This is the single most important material difference, and most product descriptions don’t make it obvious. Acrylate adhesives are the standard in medical tape and work well for short-term use. But overnight wear on the delicate skin around your lips is a different challenge. A study on facial skin found that silicone tape produced fewer injuries across the board: less skin stripping, less irritation, and less contact dermatitis compared to acrylate options.
If you have sensitive skin, eczema-prone skin, or tend to react to bandage adhesives, look specifically for “silicone adhesive” on the label. Some purpose-built mouth tapes use silicone; many still use acrylates. The packaging will usually say “medical-grade adhesive” without specifying the type, so you may need to check the brand’s website or contact them directly.
How to Apply It
The simplest technique is a single vertical strip running from just above the upper lip to just below the lower lip. This keeps your lips together at the center while leaving the corners of your mouth unsealed, so air can escape sideways if needed. It’s the safest starting point for beginners because it doesn’t fully seal the mouth.
Full-coverage horizontal strips or H-shaped strips provide a stronger seal and are what most purpose-built products use. These are better at preventing mouth breathing but leave less room for emergency airflow. Products with built-in breathing vents (like SomniFix, MyoTape, and VIO2) address this by allowing a small amount of air through the tape itself.
A few practical tips for comfortable use: make sure your lips and the skin around them are clean and dry before applying. Oils, moisturizers, and stubble all weaken adhesion. Some people apply a thin layer of lip balm directly on the lips (not the surrounding skin) to make removal easier in the morning. When removing tape, peel slowly and pull parallel to the skin rather than straight outward.
What Mouth Taping Actually Does
The goal is to keep your mouth closed during sleep so you breathe through your nose. Nasal breathing warms and filters air before it reaches your lungs, and the paranasal sinuses produce nitric oxide during nasal breathing. Nitric oxide is a natural vasodilator that improves blood circulation, enhances oxygen uptake, and helps maintain upper airway muscle tone during sleep.
Clinical studies have shown modest improvements in sleep-disordered breathing with mouth taping. One study found that mouth taping reduced the apnea-hypopnea index (a measure of breathing interruptions per hour) from 8.3 to 4.7. Another reduced it from 12 to 7.8. These are meaningful shifts in mild cases, though both groups remained in the mild range after taping.
Who Should Avoid Mouth Taping
A systematic review published in PLOS One found that nearly every clinical study on mouth taping excluded participants who couldn’t breathe comfortably through their nose. The research is clear: mouth taping carries real risks if your nasal airway is compromised. Specific conditions that make mouth taping unsafe include nasal obstruction or chronic congestion, a deviated septum, chronic allergies, sinus infections, enlarged tonsils, and heart conditions.
Mouth taping is also not recommended for people with moderate or severe obstructive sleep apnea. The reviewers noted that it “may impose dangers rather than benefits in these patients,” including the risk of oxygen desaturation and respiratory distress. One study excluded participants with a BMI over 30, suggesting higher body weight may increase the risks.
Before you start, test your nasal breathing while awake. Close your mouth and breathe through your nose for two to three minutes. If this feels difficult, strained, or if one nostril is completely blocked, mouth taping is not a good fit without addressing the underlying nasal issue first.
Alternatives to Tape
If tape on your face isn’t appealing or isn’t safe for your situation, nasal strips and nasal dilators can help encourage nasal breathing by physically opening the nasal passages. Strips adhere to the outside of your nose, while dilators sit inside the nostrils. Neither one keeps your mouth closed, but by making nasal breathing easier, they can reduce how often your mouth falls open during sleep.
For snoring or mild sleep apnea specifically, oral appliances (custom-fitted devices that hold your lower jaw slightly forward) are a clinically supported alternative. For moderate to severe sleep apnea, CPAP machines remain the standard treatment and are far more effective than mouth taping at keeping the airway open.
