If a mouthpiece didn’t stop your snoring, mouth breathing may be the reason. Here is what actually works.
Mouth breathers face a unique snoring challenge. A standard MAD mouthpiece works by advancing the lower jaw forward, which tightens the airway tissue and prevents the vibrations that cause snoring. But if you sleep with your mouth open, air bypasses this mechanism entirely — it streams in through your open mouth, vibrating soft tissue regardless of jaw position. The mouthpiece is doing its job. The open mouth is undermining it.
This is why mouth breathers often try mouthpiece after mouthpiece and say "it didn’t work." They are not wrong that the mouthpiece failed them. But the mouthpiece was never designed to solve their specific problem. A standard MAD device addresses jaw position. It cannot close your mouth. Solving mouth-breathing snoring requires addressing both variables simultaneously — jaw position and mouth closure.
Many mouth breathers do not realize they breathe through their mouths during sleep. If several of the following apply to you, mouth breathing is likely a factor in your snoring:
If you recognize three or more of these signs, a standard mouthpiece alone is unlikely to solve your snoring. You need a solution that also keeps your mouth closed during sleep.
The Snorple Complete System pairs the Snorple mouthpiece with a soft chin strap designed to work together as an integrated solution for mouth-breathing snorers. This is not two separate products bolted together — it is a system engineered for the specific dual-vector problem of mouth-breathing snoring.
The chin strap keeps the mouth closed during sleep, eliminating the open-mouth airflow that makes mouthpieces ineffective for mouth breathers. With the mouth closed, the mouthpiece’s MAD + TSD mechanism can do its job: advancing the jaw forward to tighten airway tissue and stabilizing the tongue to prevent it from falling back. Together, the two components eliminate both vectors of mouth-breathing snoring simultaneously.

The mouthpiece alone ($69) is the right choice for nasal breathers. The Complete System ($79) is the right choice for mouth breathers. The $10 difference is minimal relative to the difference in outcomes for someone who sleeps with their mouth open.
Nasal strips and dilators are commonly tried by snorers who suspect their nose is the problem. They work by mechanically widening the nasal passages, which reduces airflow resistance through the nose. For snorers whose nasal passages are structurally narrow or temporarily congested, this can help.
But nasal strips do not solve mouth-breathing snoring. If you are breathing through your mouth during sleep — whether due to habit, anatomy, or nasal congestion — making the nasal passages wider does not change where the air goes. The mouth is still open. Air still flows through the mouth. Soft tissue still vibrates.
Nasal strips address nasal obstruction. A chin strap addresses the mouth-open behavior. These are different problems requiring different solutions. If nasal strips have not worked for you, it is a strong signal that your snoring is mouth-breathing related, not nasal-obstruction related.
"I’m a mouth breather so I got the Complete System. Zero snoring. First night."
"The combo is worth every penny. The chin strap keeps my mouth closed and the mouthpiece does the rest."
"I tried three other mouthpieces. Didn’t work. Then I realized I was a mouth breather. Complete System fixed it in one night."
Not reliably. A MAD mouthpiece works by repositioning the jaw to tighten airway tissue and reduce vibration. But if you sleep with your mouth open, air enters through the mouth rather than the nose, bypassing the area where the mouthpiece is most effective. The mouthpiece addresses jaw position; it cannot prevent the mouth from falling open during sleep. For mouth breathers, a chin strap is necessary to close the mouth and allow the mouthpiece to work as intended.
No. Snorple’s chin strap is made from soft, breathable fabric and is fully adjustable to fit different head sizes and shapes. Unlike rigid chin cups, the fabric design conforms to your face and does not create pressure points. Most users adapt within the first one to two nights and report that the strap becomes unnoticeable during sleep.
Yes. The Complete System is designed to encourage nasal breathing, not restrict breathing overall. The chin strap keeps the mouth gently closed, which naturally directs airflow through the nasal passages. For most users, this is not only comfortable but beneficial — nasal breathing filters and humidifies air before it reaches the lungs, and is associated with better sleep quality overall.
Snorple backs the Complete System with a 30-day money-back guarantee. If you try the system for at least one week and do not see a reduction in snoring, you can return it for a full refund. Most customers with mouth-breathing snoring notice results within the first one to three nights of wearing both components together.
