The result is narrowing of the oropharynx, turbulent airflow, and snoring, or in more significant cases, obstructive sleep apnoea.
- Loud or chronic snoring
- Waking unrefreshed despite adequate hours of sleep
- Daytime fatigue or sleepiness
- Morning headaches
- Dry mouth or sore throat on waking
- A bed partner reporting apnoeic episodes or pauses in breathing
- Difficulty concentrating or poor cognitive performance attributable to sleep disruption
The link between tongue posture and airway
The tongue is a primary airway stabiliser during sleep. When it rests correctly against the palate, it holds the oropharyngeal airway open and supports nasal breathing. A tongue restricted by a tight frenulum habitually falls backward when muscle tone decreases during sleep. This reduces the cross-sectional area of the airway, increases turbulence, and produces snoring. In more significant cases, the airway collapses entirely: obstructive sleep apnoea.
Myofunctional therapy and airway
Myofunctional therapy, retraining the tongue to rest correctly and maintain airway muscle tone during sleep, has an emerging evidence base as an adjunct or alternative to CPAP for mild to moderate sleep-disordered breathing. For adults with an underlying tongue tie, functional frenuloplasty followed by targeted myofunctional preparation and rehabilitation addresses the structural root of the problem.
Where tongue tie sits in the wider picture
We are not suggesting that tongue tie is the only cause of sleep apnoea. A comprehensive sleep evaluation may include ENT assessment, a sleep study, and cardiovascular assessment. Tongue tie is one contributor that is frequently missed. If you have sleep-disordered breathing and you have never had your tongue function assessed, that assessment should be part of your workup.
Our approach: Release Restrictions, Retrain Function, Relieve Tension, includes the myofunctional rehabilitation that is essential for sustaining airway improvement after frenuloplasty.
The National Tongue Tie Centre was established in 2007 as Ireland's first clinic dedicated entirely to the assessment and treatment of tongue tie. The centre treats over 1,000 patients per year and receives patients from across Ireland and internationally.

Frequently asked questions
Yes. Habitual snoring without confirmed apnoea still represents airway narrowing and increased breathing effort during sleep. It is associated with poorer sleep quality and long-term cardiovascular risk. If tongue function is contributing to airway narrowing, treating it is worthwhile even in the absence of a formal sleep apnoea diagnosis.
For some people, yes. CPAP is highly effective but many find it difficult to tolerate long-term. Myofunctional therapy combined with frenuloplasty, where a tongue tie is present, can reduce the severity of sleep-disordered breathing and in some cases allow CPAP pressure to be reduced. We would advise you to work with your sleep physician alongside any functional intervention.
Mandibular advancement devices work by repositioning the jaw to open the airway. If tongue restriction is contributing to the airway problem, a functional assessment alongside the device is appropriate. The two approaches address different aspects of the same problem.
Please seek urgent assessment from your GP for a sleep study referral. Witnessed apnoea is a clinical indication for formal sleep investigation. A tongue tie assessment is appropriate as part of the wider workup, but the immediate priority is confirming the diagnosis and ruling out significant cardiovascular risk.
Yes. A tongue tie present since birth means a lifetime of low tongue posture and compromised airway muscle function during sleep. Many adults are surprised to find that a structural issue present their entire lives can still be addressed meaningfully in their 30s, 40s, or beyond.
Book a comprehensive assessment at the National Tongue Tie Centre. Our clinical team will complete a comprehensive functional assessment, explain what we find, and give you an honest discussion of what frenuloplasty is likely and unlikely to achieve in your case. Call us, complete our online enquiry form, or visit www.tonguet.ie. Clinics in Clonmel, Co. Tipperary and Naas, Co. Kildare.
Frenuloplasty is a surgical procedure. Risks, benefits, and individual expectations will be discussed in full at your assessment appointment before any decision to proceed is made.
