Effective Tongue Thrust Treatment for Adults
Tongue thrust treatment for adults addresses a swallowing pattern in which the tongue presses forward against or between the upper and lower teeth. Although it often begins in childhood, the habit can persist into adulthood. When left untreated, it can contribute to bite changes, affect certain speech sounds, and even reverse years of orthodontic treatment.
Our guide explains how tongue thrust treatment works for adults, what the process involves, how long treatment may take, and the results many people can expect. It is designed for adults who notice a forward tongue posture, a gap that has returned between their teeth, or speech changes such as a lisp. Understanding that tongue thrust is treatable at any age is often the first step toward lasting improvement.
Key Takeaways
Tongue thrust treatment for adults focuses on retraining tongue posture and swallowing patterns. Most adults address the issue through speech therapy, which trains them to achieve correct tongue placement.
Adults can correct tongue thrust at any age. Treatment often targets tongue posture, swallowing habits, and the muscle patterns that have developed over the years.
Common causes include mouth breathing, thumb sucking, allergies, enlarged tonsils, and tongue-tie. Without treatment, tongue thrust can contribute to bite changes, orthodontic relapse, and some speech difficulties.
Speech therapy is effective for many adults. Treatment often takes three to six months of consistent practice under the guidance of a speech-language pathologist or orthodontist.

What Is Tongue Thrust in Adults?
Tongue thrusting in adults is an oral habit that involves pushing the tongue forward against the upper teeth. During swallowing and at rest, the tongue moves forward instead of resting against the roof of the mouth. The pattern also goes by other names, including orofacial myofunctional disorder, reverse swallow, and deviate swallowing pattern.
A normal swallow follows a wave-like motion. The tongue lifts against the roof of the mouth and helps move food backward. With a forward tongue position, the tongue pushes ahead instead, placing pressure on the teeth rather than the palate with every swallow.
The force adds up. A person swallows roughly 1,000 to 2,000 times a day, so a habit that nudges the teeth on every swallow applies constant pressure over months and years.
As many as 67 to 95 percent of children show some tongue thrust. The pattern usually fades, yet it lingers in an estimated 5 to 15 percent of older children and adults.
Many adults are surprised to learn the pattern has a name. They have lived with a forward tongue position, a faint lisp, or a swallow that feels off, without realizing the tongue muscles are driving it. Naming the habit makes it treatable because the right exercises target exactly those muscles and that swallowing pattern.
What Causes Tongue Thrust in Adults?
Tongue thrust in adults usually traces back to childhood oral habits, such as thumb sucking, left uncorrected. Over time, the muscles learn the forward pattern and keep repeating it. Several causes can start the habit or keep it going, and many adults have more than one.
The most common causes include:
Childhood sucking habits: prolonged thumb sucking, prolonged pacifier use, or bottle feeding that trains the tongue to move forward.
Mouth breathing: chronic breathing through the mouth keeps the lips parted and the tongue low, which encourages a forward resting posture.
Enlarged tonsils or adenoids: swollen tissue at the back of the throat pushes the tongue forward to make room.
Chronic allergies and nasal congestion: a blocked nose forces breathing through the mouth, which perpetuates the cycle.
Tongue-tie: a short or tight band under the tongue, called ankyloglossia, can restrict how high the tongue lifts.
Anatomy and habit: a large tongue, a high, narrow palate, or plain muscle memory can hold the thrust in place.
Stress and tension add to it for some adults, who press their tongue against their teeth when they concentrate. Whatever the trigger, the result is the same forward push repeated thousands of times a day. Because breathing through the mouth both causes and signals the problem, easing any airway issue is part of the plan.
What Are the Signs of Tongue Thrust in Adults?
The signs of tongue thrust in adults show up in the teeth, the swallow, and certain speech sounds. Most are easy to notice once you know the pattern, and many adults have more than one.
Common signs include:
An open bite: a visible gap between the upper and lower teeth when the back teeth are closed.
Speech sound changes: a lisp or distortion on s and z sounds, where the tongue slips between the teeth.
A visible swallow: the tongue protrudes forward and the chin tenses with each swallow, sometimes with difficulty swallowing.
Open-mouth rest and breathing through the mouth: the lips stay parted while the tongue rests low and forward.
Shifting teeth: new gaps, crowding, or misaligned teeth that shift in adulthood.
On their own, some of these signs can point to other issues, so a speech-language pathologist confirms the pattern during an exam. Tongue thrust can also cause speech difficulties, such as a lisp, that leave adults self-conscious. If several signs sound familiar, the next step is a professional assessment.
A speech-language pathologist or an orthodontist diagnoses tongue thrust through a comprehensive evaluation that includes an oral exam and an articulation assessment. X-rays are sometimes used to evaluate jaw positioning when the bite is affected.
Signs of Tongue Thrust in Adults: What to Look For and What It Means

How Is Tongue Thrust Treated in Adults?
Tongue thrust is treated mainly with speech therapy, often alongside orthodontic care. A speech-language pathologist or a trained orthodontist leads the work, and the plan is matched to the cause and the adult's goals. Because the habit often blurs s and z sounds, the plan can also include articulation therapy for adults.
What Speech Therapy Involves
Speech treatment retrains tongue posture and swallowing patterns through targeted exercises. Early sessions often focus on establishing a stable resting position before moving to swallowing tasks. Many people attend 10 to 20 sessions over several months, although the exact number depends on the severity of the habit and how consistently exercises are practiced.
Sessions often start weekly, then move to every two weeks, and finally to monthly as the new swallowing pattern holds. Each visit lasts around 30 to 60 minutes, and the real progress happens between visits through daily home practice. An interdisciplinary approach works best, so the speech therapist often coordinates with a dentist or orthodontist.
Some people also work with an orofacial myofunctional therapist. Many of these providers are speech-language pathologists who have completed additional training in orofacial myology, although professionals from other healthcare backgrounds may also hold this specialty. Their work focuses on tongue posture, lip posture, breathing patterns, and swallowing mechanics, often alongside speech treatment and orthodontic care.
Tongue Thrust Exercises
A few core exercises rebuild tongue posture, proper coordination, and a healthy swallow; together, they correct tongue thrust. A speech-language pathologist tailors them to each adult, but most programs include some version of these:
The spot exercise: hold the tongue tip on the ridge behind the upper front teeth to learn the correct resting posture.
The 4S sequence: spot, salivate, squeeze, and swallow, is practiced many times a day to retrain proper swallowing.
The Cheerio hold: Hold a Cheerio between the lips while keeping the teeth slightly apart. This exercise can help strengthen the lips and support better oral posture.
Nasal breathing practice: sealing the lips encourages nasal breathing and supports a higher tongue placement.
Consistency matters more than intensity. Short daily sessions work better than occasional long ones, and they help adults stop tongue thrusting once the old tongue-thrusting pattern fades in everyday swallowing and speech.
Orthodontics, Appliances, and Tongue-Tie Release
Speech treatment is often paired with orthodontic care, especially when tongue thrust has contributed to changes in bite or tooth movement. Braces, aligners, and other orthodontic appliances can correct the bite, while devices such as a tongue crib may help discourage the forward tongue movement that reinforces the habit.
Tongue-tie can sometimes contribute to tongue thrust, but its impact varies from person to person. Some adults benefit from an evaluation by a dentist, oral surgeon, or speech-language pathologist with experience in orofacial myofunctional disorders.
In select cases, a tongue-tie release procedure may be recommended when restricted tongue movement is clearly affecting function. More often, treatment focuses on improving tongue posture and swallowing patterns, regardless of whether a tongue-tie is present.
Adults with both tongue thrust and bite changes often achieve the most stable results when speech treatment and orthodontic care work together. Coordinating care across providers helps address both the habit and its effects on the teeth and jaw.
How Long Does Speech Therapy Take?
Most adults see meaningful change in three to six months. The timeline depends on the cause and how long the habit has been in place, so a simple habit can be corrected faster while one tied to a tongue-tie or airway problem can take longer. The program continues until the new swallowing pattern holds on its own.
Progress is gradual and rests on daily habits and maintaining motivation between sessions. Adults who practice daily tend to reach a stable, automatic swallow, while those who do the exercises less often need more time. Addressing tongue thrust early tends to speed the results.
Online speech therapy works well for tongue thrust because the exercises rely on watching, copying, and feedback that carry over cleanly to video. Fit depends on the person, yet most adults do well after comparing in-person and online options. Many also weigh the cost of speech therapy, which a provider can review along with insurance before the work begins.
Why Treating Tongue Thrust Matters: Bite, Relapse, and Sleep
Left uncorrected, problematic tongue thrust does more than push the teeth. The same forward pressure that shapes the bite can cause speech issues, affect orthodontic results, and even reach into sleep. Knowing what is at stake is part of why adults choose to correct tongue thrust.
Bite and Dental Misalignment
The clearest consequence is an anterior open bite, a gap where the upper and lower front teeth no longer meet. Constant forward pressure can also cause crowding, gaps, and misaligned teeth, disrupting the tooth alignment that took years to develop.
These dental problems make chewing harder and can affect oral health. Over time, the strain can contribute to jaw pain, and the new bite can cause difficulty pronouncing certain sounds.
Orthodontic Relapse After Braces
Tongue thrusting is a leading cause of teeth shifting back after braces. If the anterior thrust continues, it can undo the tooth alignment achieved by orthodontic treatment, a pattern known as orthodontic relapse. Smithpeter and Covell reported in 2010 that combining speech therapy exercises with orthodontics reduced this relapse compared with appliances alone.
Airway, Breathing, and Sleep
A low, forward tongue posture often accompanies mouth breathing, and the two are sometimes linked to sleep-related breathing difficulties. When the tongue rests low in the mouth, the airway may have less support, which can contribute to snoring and disrupted sleep. Improving nasal breathing and tongue posture may support better airway function, although sleep problems often have multiple causes.
What We See Working With Clients
Many adults don't realize they have a tongue thrust until another problem brings it to their attention. A returning gap between the front teeth, a lisp that never fully went away, or orthodontic treatment that doesn't seem to hold often prompts the first evaluation.
One client was a young professional who had completed orthodontic treatment twice. Each time, a gap slowly reopened between her front teeth. She assumed her teeth were simply shifting again.
During our evaluation, we noticed a forward tongue posture at rest and a tongue thrust swallow pattern. As she learned to keep her tongue on the roof of her mouth and changed how she swallowed, the constant pressure against her teeth decreased. Her orthodontist was then able to maintain the correction more successfully.
Another client came to us because of speech concerns. He worked in sales and felt self-conscious about a slight lisp during presentations and video meetings. He had never connected the speech pattern to the position of his tongue.
The assessment showed that his tongue rested against his front teeth throughout the day and pushed forward during swallowing. As his tongue posture improved, his speech became clearer, and he reported feeling more confident during client conversations.
A common pattern we see is that adults focus on the visible problem, such as shifting teeth or unclear speech, while the tongue habit remains unnoticed. Once the underlying pattern is identified, treatment can target the source rather than the symptoms alone.
Frequently Asked Questions About Tongue Thrust in Adults
1. Can tongue thrust be corrected in adults?
Yes, tongue thrust can be corrected at any age. Speech therapy retrains the tongue's resting posture and swallow, and most adults overcome tongue thrust with steady practice. Studies report successful correction in about 75 percent of treated cases.
2. How long does tongue thrust treatment for adults take?
Most adults need about three to six months. The timeline depends on the cause, the strength of the habit, and how consistently the exercises are practiced. A thrust linked to a tongue-tie or airway issue can take longer.
3. What is the difference between tongue thrust and tongue-tie?
Tongue thrust is a habit, while tongue-tie is a physical restriction. The thrust is a forward swallowing pattern, and the tie is a short band under the tongue that limits movement. A tongue-tie can cause a thrust and may require release before speech therapy.
4. Is tongue thrust linked to sleep apnea?
It can be, through chronic mouth breathing and low tongue posture. A tongue that rests low and forward provides less support to the airway, which can contribute to snoring and sleep-disordered breathing. Treating tongue thrust can be one part of a broader airway plan.

We also collaborate with dentists, orthodontists, and other providers when coordinated care is needed.
If you're concerned about tongue thrust, shifting teeth, or a persistent lisp, contact us to learn whether speech therapy may be a good fit for your goals.
Summary
Tongue thrust treatment for adults retrains the tongue to rest against the roof of the mouth and swallow without pushing against the teeth. Therapy involves working with a speech-language pathologist. Left uncorrected, the forward swallowing pattern can drive a misaligned bite, dental problems, and orthodontic relapse, yet the habit responds to speech therapy at any age.
With consistent practice over three to six months, most adults overcome tongue thrust and protect their teeth, speech, and airway for the long term.
