Tethered Oral Tissues
Tethered Oral Tissues (TOTs) refer to restrictive bands of tissue, known as frenulum restrictions, that limit the movement of the tongue, lips, or cheeks.
These restrictions can affect oral function in a variety of ways, impacting feeding, speech, breathing, and overall oral development. While tongue ties are the most commonly recognized, lip and cheek ties can also play a significant role in oral dysfunction.

A tongue tie occurs when the lingual frenulum (the band of tissue under the tongue) is too short, thick, or tight, restricting tongue movement. This restriction affects multiple areas of health and development:
Craniofacial Development
The tongue acts as nature’s palatal expander by resting lightly suctioned to the roof of the mouth. This pressure encourages optimal jaw growth and facial development. When a tongue tie is present, the tongue cannot maintain proper posture, leading to:
A narrow palate and crowded teeth due to lack of lateral tongue pressure on the maxilla
A long, narrow face caused by vertical maxillary growth from low tongue posture
A “gummy smile” resulting from excessive upper jaw gum tissue due to improper vertical growth
Poor airway development, increasing the risk of sleep-disordered breathing and sleep apnea
Eating and Swallowing
During normal swallowing, the tongue reaches the hard and soft palate to guide food down the throat. A tongue tie limits this movement, leading to:
Food feeling “stuck” in the back of the mouth
Children avoiding certain textures, appearing to be "picky eaters"
Increased risk of choking or improper swallowing patterns
Oral Hygiene and Decay Prevention
The tongue plays a vital role in naturally clearing food debris from the teeth and gums. A restricted tongue has limited mobility, causing:
Food particles to remain trapped, increasing plaque buildup
Higher risk of cavities and gum disease due to poor oral clearance
Speech and Articulation Issues
A tethered tongue affects speech clarity by restricting proper tongue movement needed for sounds such as “L,” “R,” “T,” “D,” “N,” and “S.” While myofunctional therapy is not speech therapy, many individuals experience improved articulation following a tongue-tie release and targeted therapy exercises.
How Myofunctional Therapy Can Help
A tongue-tie release (frenectomy) alone is not enough to restore full function. Myofunctional therapy is essential before and after the release to:
Strengthen and retrain the tongue for proper rest posture
Improve swallowing and breathing patterns
Support optimal healing and prevent reattachment

A lip tie occurs when the labial frenulum—the tissue connecting the upper lip to the gum—is unusually short, thick, or tight, restricting the upper lip's movement. This restriction can impact various aspects of health and development across different age groups.
Infants
In infants, a lip tie can lead to breastfeeding challenges, such as:
Difficulty latching
Prolonged feeding times
Poor weight gain
Maternal discomfort
Children
As children grow, an untreated lip tie can contribute to:
Speech difficulties: Restricted lip movement may affect the articulation of sounds like "B," "P," and "M."
Dental issues: A prominent gap between the upper front teeth (diastema) can develop due to the tight frenulum.
Oral hygiene challenges: Limited lip mobility can make brushing and flossing difficult, increasing the risk of cavities and gum disease.
Eating difficulties: Children may have trouble managing food in their mouths, leading to messy eating or picky eating habits.
Adults
In adults, an untreated lip tie may result in:
Gum recession: Tension from the tight frenulum can pull on the gum tissue, leading to recession.
Persistent gap between teeth
Speech issues
Oral hygiene problems
Treatment and Myofunctional Therapy
A common treatment for a lip tie is a frenectomy, a minor surgical procedure that releases the tight frenulum. However, to ensure optimal outcomes, myofunctional therapy is often recommended before and after the procedure. This therapy focuses on:
Enhancing lip mobility: Exercises aim to improve the range of motion and strength of the lips.
Correcting oral posture: Training the lips and tongue to rest in proper positions supports overall oral health.
Improving swallowing patterns: Therapy can help establish efficient and effective swallowing techniques.
By combining surgical intervention with myofunctional therapy, individuals can achieve improved oral function and prevent potential complications associated with lip ties.

A buccal tie occurs when the buccal frenum—the connective tissue linking the inner cheek to the gums—is unusually short, thick, or tight, restricting cheek movement. While less common than tongue or lip ties, buccal ties can still impact oral function and development.
Infants
In infants, restrictive buccal frena can:
Affect breastfeeding: Limited cheek mobility may hinder the baby's ability to achieve a proper latch, leading to feeding difficulties.
Restrict mouth opening: A tight buccal frenum can limit the gape necessary for effective breastfeeding.
Children
As children grow, untreated buccal ties may lead to:
Speech challenges: Restricted cheek movement can affect the articulation of certain sounds, potentially leading to speech difficulties.
Eating difficulties: Limited cheek mobility may cause challenges in chewing and managing food, leading to messy eating or food aversions.
Oral hygiene issues: Difficulty in brushing due to restricted cheek movement can increase the risk of cavities and gum disease.
Adults
In adults, unresolved buccal ties might contribute to:
Gum recession: Tension from a tight buccal frenum can pull on the gum tissue, leading to recession over time.
Diagnosis and Treatment
Healthcare providers assess buccal ties through visual inspection, palpation, and functional evaluation. If a buccal tie is identified and deemed problematic, a minor surgical procedure called a frenectomy may be performed to release the tight frenum. Post-operative care often includes myofunctional therapy to improve oral function and prevent reattachment.
Myofunctional Therapy & Tethered Oral Tissues
At Birch and Bloom, we take a functional approach to evaluating tethered oral tissues. This includes assessing range of motion, oral posture, breathing, swallowing, and identifying muscular compensations. A frenectomy (surgical release) may be necessary, but releasing the tissue alone does not resolve the underlying dysfunction—myofunctional therapy is essential before and after the release to restore proper function.
Myofunctional therapy helps:
Strengthen and retrain oral muscles
Support proper tongue and lip posture
Improve breathing and swallowing patterns
Aid in healing and reduce the risk of reattachment
A Holistic and Collaborative Approach
For infants, a release and bodywork may be enough to improve feeding. But for older children and adults, additional providers may be needed to fully address the root of the problem. Common referrals include:
ENTs for nasal obstructions or airway evaluation
Sleep specialists if sleep apnea or breathing issues are present
Airway orthodontists for palate expansion or alignment
Bodyworkers (craniosacral, chiropractic, lymphatic, massage) for tension and alignment
TMJ specialists, allergists, or functional medicine providers, depending on your unique case
Just like physical therapy is essential after orthopedic surgery, myofunctional therapy is vital for achieving functional improvements after a tongue tie release. Therapy re-educates the muscles, supports healing, and helps you or your child develop new, healthy oral habits.
If you suspect a tongue tie or orofacial myofunctional disorder, start with a comprehensive evaluation. You’ll gain clarity on the condition, understand your treatment options, and take the first step toward better function, breathing, and well-being.
