Is using mouth tape really good for your wellbeing? Cosmetic Dentist Dr Raj Juneja, Principal Dentist at Face Teeth Smile Dental Clinics, shares what you need-to-know before reaching for the tape
Mouth taping — the viral bedtime trend where you place a small piece of tape over your lips to encourage nasal breathing — has taken social media by storm. Fans claim it improves sleep quality, boosts energy, and even enhances oral health.
But is it really a good idea? Cosmetic Dentist Dr Raj Juneja, Principal Dentist at Face Teeth Smile Dental Clinics, explains what you should know before reaching for the tape.
1. It’s not a quick fix for your oral health
While mouth taping may promote nasal breathing (which can help reduce dry mouth and bad breath), it won’t solve underlying dental or airway problems. If you’re mouth breathing because of congestion, allergies, or jaw positioning, skip the DIY solutions and see a dentist or doctor to find the real cause.
2. Chronic mouth breathing can affect your smile
Breathing through your mouth at night dries out your oral tissues and reduces saliva flow — and saliva is your mouth’s natural defence. Without enough of it, you’re more prone to cavities, gum inflammation, and staining. Over time, that can impact both your oral health and the appearance of your smile.
3. There are safer ways to encourage nasal breathing
Before resorting to mouth tape, try nasal strips, saline rinses, or addressing any sinus congestion. If you suspect that your jaw position or airway anatomy plays a role, book a consultation with your dentist. They can help identify issues like a narrow palate or misaligned bite that might be making nasal breathing more difficult.
4. Never use standard adhesive tape
If you do decide to experiment, always use medical-grade mouth tape made specifically for sleep. Never use household tape or duct tape — they can cause skin irritation, allergic reactions, or even restrict breathing if applied incorrectly.
5. It’s not suitable for everyone
Those with breathing difficulties, sinus problems, sleep apnoea, or anxiety should avoid mouth taping altogether. Anything that restricts airflow can be risky if you already struggle with breathing during sleep. Always check with your dentist or GP before trying this trend.
(If you suspect sleep apnoea or nighttime breathing problems, seek out a dentist with specific experience in sleep apnoea and airway management. You may benefit from a custom specialist mouthguard designed to support the airway and improve breathing safely — without the risks of taping.)
6. Focus on oral health basics first
No trend can replace good habits. Regular brushing, flossing, and dental check-ups remain the foundation of a healthy smile. Focus on consistent care — not overnight hacks — to keep your mouth (and your sleep) in the best possible shape.
