How To Stop My Tongue From Pushing My Teeth?

Tongue thrust is a real condition, not a bad habit you can simply decide to stop. It happens when the tongue pushes forward against the front teeth during swallowing, speaking, or at rest instead of pressing against the roof of the mouth. The most reliable way to change it is to work with a dentist, orthodontist, or speech-language pathologist who can identify why it is happening and guide you through targeted therapy. Willpower alone rarely fixes it, because the pattern is often automatic and tied to the shape of your mouth, your breathing, or how you swallow.

What Is Tongue Thrust and Why Does It Happen?

Swallowing looks simple. It is not. A typical swallow involves the tongue pressing upward against the hard palate — the bony front section of the roof of your mouth — while the teeth stay together and the lips seal. In tongue thrust, the tongue moves forward instead, pushing against or between the front teeth.

This pattern is normal in infants. Babies swallow with their tongues forward because it helps them nurse. As children grow and their swallowing matures, most shift to the adult pattern. For some people, that shift does not fully happen, or it reverses later.

Several things can drive tongue thrust:

• Mouth breathing. When the nose is chronically blocked, the tongue rests low and forward instead of against the palate. This is one of the most common contributors.
• Enlarged tonsils or adenoids. These can block airflow and push the tongue forward.
• An open bite or other bite problems. The way the teeth meet can reinforce the forward tongue position.
• Thumb sucking or prolonged pacifier use. These habits can shape the bite and tongue posture in early childhood.
• Neurological conditions. In some cases, tongue thrust is linked to conditions affecting muscle control.
• Macroglossia. An unusually large tongue, which is uncommon, can contribute.

One clarification worth making: tongue thrust and “tongue posture” are related but not identical. Tongue thrust refers to the pressure during swallowing or speaking. Resting tongue posture — where your tongue sits when you are not doing anything — is a separate but connected issue. Many people have problems with both.

How Do I Know If I Have Tongue Thrust?

You may not notice it yourself. Tongue thrust is often identified by a dentist or orthodontist during a routine exam, especially if teeth are shifting or an open bite is present.

Signs that can point to it include:

• An open bite, where the front upper and lower teeth do not touch when you bite down
• Teeth that have shifted after orthodontic treatment, particularly the front teeth flaring outward
• Difficulty saying certain sounds, especially “s,” “z,” “sh,” or “th”
• A lisp or slurred speech
• Mouth breathing, especially during sleep
• Slow or messy eating, or food falling out of the mouth
• Jaw pain or TMJ discomfort in some cases

None of these signs prove tongue thrust on their own. An open bite, for example, can have several causes. A proper evaluation looks at how you swallow, how you speak, where your tongue rests, and how your teeth and jaws are shaped.

Can You Stop Tongue Thrust on Your Own?

For mild cases, some people can improve tongue posture with consistent awareness and simple exercises. For moderate to severe cases, self-correction is unlikely to be enough.

The reason is that swallowing is largely automatic. You swallow hundreds of times a day, mostly without thinking about it. Trying to consciously control every swallow is not realistic. What therapy does is retrain the automatic pattern over time through repetition.

Some general awareness exercises that speech-language pathologists sometimes use include:

• Placing the tongue tip on the bumpy ridge just behind the upper front teeth (the alveolar ridge) and holding it there briefly
• Practicing swallowing with the tongue in that position while keeping the teeth together
• Noticing where the tongue rests during the day and gently repositioning it to the palate

These are not a treatment plan. They are examples of the kind of work involved. Doing them incorrectly can reinforce the wrong pattern. A clinician can watch what your tongue actually does and correct it in real time, which you cannot do on your own.

What Does Professional Treatment for Tongue Thrust Involve?

Treatment usually depends on what is causing the thrust and how much it is affecting your teeth, speech, or breathing.

Speech-language therapy is the most common approach. A speech-language pathologist evaluates your swallowing and speech patterns, then designs exercises to retrain tongue placement. Therapy typically involves regular sessions over weeks to months, with home practice in between. Progress depends on the individual, the severity of the pattern, and how consistently the exercises are done.

Orthodontic treatment may be needed if the tongue thrust has already moved teeth or created an open bite. Braces or aligners can move teeth back into position, but if the tongue thrust continues, the teeth may shift again. This is why orthodontists often recommend addressing the tongue pattern alongside or before orthodontic work.

Myofunctional therapy is a specialized form of therapy that targets the muscles of the tongue, lips, and face. It is sometimes used alongside speech therapy or orthodontics. The evidence for myofunctional therapy is growing but still limited compared to more established treatments. Some studies suggest it can help improve tongue posture and swallowing patterns, but more high-quality research is needed.

Treating underlying causes matters. If chronic mouth breathing from allergies or enlarged tonsils is driving the tongue forward, addressing that issue may be necessary before tongue retraining can work. In some cases, an ear, nose, and throat specialist (ENT) may need to evaluate airway issues.

Appliances such as tongue cribs or palatal expanders are sometimes used in children. These devices physically block or guide the tongue. They are typically used as part of a broader treatment plan, not on their own.

Does Tongue Thrust Need to Be Treated?

Not always. Mild tongue thrust that is not affecting teeth, speech, or function may not need active treatment. Some children outgrow it as their mouths develop.

Treatment is more likely to be recommended when:

• Teeth are shifting or an open bite is getting worse
• Speech is affected
• Orthodontic treatment has been done and teeth are relapsing
• There are breathing or sleep issues
• The pattern is causing jaw pain or difficulty eating

The decision to treat is usually made with input from a dentist, orthodontist, or speech-language pathologist. There is no single rule that applies to everyone.

What About Tongue Thrust in Children?

Tongue thrust is more common in children, and it is often identified during routine dental visits. In young children, the pattern may resolve on its own as the mouth grows and swallowing matures.

For children who need treatment, speech therapy and orthodontic care are the main options. Age matters. Younger children may respond well to therapy because their patterns are less entrenched. Older children and teenagers may need a combination of therapy and orthodontic work.

It is worth noting that not all children with tongue thrust need treatment. A dentist or orthodontist can assess whether the pattern is likely to cause problems or whether it is something to monitor.

Can Tongue Thrust Come Back After Treatment?

Yes. Tongue thrust can return, especially if the underlying cause was not addressed. For example, if mouth breathing continues after therapy, the tongue may drift forward again.

This is why some clinicians recommend periodic check-ins after treatment, particularly if orthodontic work was involved. Retainers help hold teeth in place, but they do not retrain the tongue. If the tongue pattern returns, teeth can shift again.

Maintaining good tongue posture and addressing breathing issues can help reduce the risk of relapse. But there is no guaranteed way to prevent it.
