If an orthodontist, dentist, or speech-language pathologist has mentioned that you or your child has a tongue thrust, exercises are usually a big part of the solution. A tongue thrust is when the tongue pushes forward against or between the front teeth during swallowing, speech, or at rest — and because we swallow hundreds of times a day, that repeated forward pressure can affect tooth alignment, speech clarity, and even facial development.
The good news: the tongue is a muscle, and muscles can be retrained. This guide walks through the most common tongue thrust exercises, including the well-known 4S method, and explains how to practice them. One important note up front — these exercises are normally taught and monitored by a qualified therapist, so treat this as a helpful starting point rather than a full treatment plan.
What Tongue Thrust Exercises Are Trying to Fix
Effective exercises are not random tongue calisthenics. They target the specific patterns behind a tongue thrust:
- Tongue resting posture — teaching the tongue to rest gently on the roof of the mouth (the palate) instead of low or pushing against the teeth.
- The swallow pattern — retraining the swallow so the tongue presses up against the palate rather than forward against the front teeth.
- Lip seal — building the lip strength to keep the mouth comfortably closed at rest.
- Nasal breathing — establishing breathing through the nose, which allows the tongue to rest in the correct spot.
The American Speech-Language-Hearing Association (ASHA) recognizes these orofacial myofunctional patterns as a legitimate clinical focus, and correcting them is the entire point of the exercises below.
Before You Start
A tongue thrust rarely exists on its own. It is often driven by an underlying cause — chronic mouth breathing, allergies or enlarged tonsils that block nasal breathing, a restricted tongue (tongue tie), or a lingering thumb or pacifier habit. Exercises work best when that root cause is identified and addressed too, which is why an evaluation matters. If nasal breathing isn't possible, for example, the tongue simply can't hold the correct resting posture no matter how many reps you do.
Most children are ready to participate meaningfully around age 7 and up, when they can follow the steps and practice independently. Adults do well because they can be consistent — and adults can absolutely retrain these patterns.
The 4S Tongue Thrust Exercise
The 4S method is the classic exercise for practicing a correct, mature swallow. The four S's are Spot, Salivate, Squeeze, and Swallow:
- Spot — Find "the spot": the small ridge on the roof of your mouth just behind your upper front teeth (the incisive papilla). Rest your tongue tip lightly there. This is home base for the tongue.
- Salivate — Let a little saliva collect in your mouth so you have something to swallow.
- Squeeze — Keeping the tip on the spot, squeeze your whole tongue up flat against the roof of your mouth. Your back teeth should be gently together and your lips relaxed and closed.
- Swallow — Swallow while holding the tongue pressed to the palate. The tongue should not push forward against or between your teeth.
Practiced regularly, the 4S sequence trains your body to swallow the correct way automatically instead of thrusting the tongue forward.
More Tongue Thrust Exercises
These exercises build the strength, coordination, and posture that make a correct swallow feel natural.
1. Find-the-Spot hold
Place your tongue tip on the spot behind your upper front teeth and hold it there. Start with short holds and build up. This trains the resting position the tongue should return to whenever it isn't busy talking or eating.
2. The tongue "suction" (cave) hold
Suction your whole tongue flat against the roof of your mouth so it sticks, then hold. You may feel a gentle pull under your tongue. This strengthens the muscles that lift and hold the tongue to the palate — the foundation of good resting posture.
3. The tongue "pop"
From the suction hold above, pull the tongue down sharply so it makes a loud "pop." This builds tongue strength and control, and it's a favorite with kids because it's a little bit fun.
4. Lip seal practice
Rest with your lips gently closed, teeth slightly apart, and tongue on the spot — breathing through your nose. Holding this relaxed, closed-mouth posture reinforces both lip seal and nasal breathing. A therapist may add resistance activities to strengthen weak lips.
5. Correct-swallow practice with water
Take a small sip of water, place your tongue on the spot, and swallow using the 4S pattern — tongue up, not forward. Practicing with liquid, then soft foods, helps carry the new swallow into real meals.
How Often Should You Practice?
Consistency matters far more than long sessions. A typical myofunctional program asks for short bouts of practice — often around 10 to 15 minutes of home exercises a day, sometimes split into a few mini-sessions — alongside weekly therapy visits over roughly 6 to 12 months. Your therapist will set the specific exercises, number of repetitions, and pace based on your progress, because the right "dose" is individual. Doing a handful of reps correctly and often beats grinding out dozens with sloppy form.
"The exercises themselves are simple — the magic is in doing them consistently and correctly until the new pattern becomes automatic. That's where having someone check your form and keep you accountable makes all the difference." — Laura Friedman, MS, CCC-SLP, QOM
Do Tongue Thrust Exercises Actually Work?
They do, with two conditions: consistency and root-cause treatment. Exercises are the active ingredient of orofacial myofunctional therapy, which is the recognized approach for correcting tongue thrust. But they are not a quick fix or a substitute for addressing why the thrust developed. If chronic mouth breathing, a tongue tie, or an oral habit is driving the pattern, exercises alone will stall until that piece is handled — which is exactly what a full evaluation sorts out.
It's also worth knowing when a home routine isn't enough. If the tongue can't reach or hold the spot, if nasal breathing is blocked, or if speech sounds like a persistent lisp, those are signs to get a professional assessment rather than push harder on the exercises.

Frequently Asked Questions
What is the 4S tongue thrust exercise?
The 4S is a simple exercise for practicing a correct, mature swallow. The four steps are Spot, Salivate, Squeeze, and Swallow: place the tongue tip on "the spot" (the ridge just behind your upper front teeth), let saliva gather, squeeze the whole tongue up against the roof of the mouth, and swallow while keeping the tongue pressed to the palate instead of pushing forward against the teeth. Repeating it builds the habit of swallowing correctly.
Do tongue thrust exercises really work?
Yes — when they are done consistently and target the root cause. Tongue thrust exercises retrain tongue resting posture, the swallow pattern, and lip seal, and research supports orofacial myofunctional therapy for correcting these patterns. Results come from daily practice over months, ideally guided by a qualified myofunctional therapist who checks your technique and addresses contributing factors like mouth breathing or a tongue tie.
How long does it take to correct a tongue thrust with exercises?
Most myofunctional therapy programs run about 6 to 12 months, combining weekly sessions with 10 to 15 minutes of daily home exercises. The timeline depends on age, consistency, and whether underlying issues (such as chronic mouth breathing or a restricted tongue) are also being addressed. The goal is for the new pattern to become automatic, not just possible.
Can adults do tongue thrust exercises?
Absolutely. It is never too late to retrain these muscles. Adults often pursue tongue thrust exercises to protect orthodontic results, reduce a persistent lisp, or address open-mouth posture. The exercises are the same in principle; adults simply tend to progress well because they can practice independently and consistently.
Can I fix a tongue thrust at home on my own?
The exercises above can help, but a lasting correction usually needs a personalized program and professional guidance. A myofunctional therapist confirms you are doing each exercise correctly and checks for underlying causes — like a tongue tie, mouth breathing, or enlarged tonsils — that home exercises alone will not resolve. Think of this guide as a starting point, not a replacement for an evaluation.
