Tongue Thrusting in Kids: Effects & How to Fix It

What Is Tongue Thrusting in Children?

Tongue thrusting is an oral habit where a child pushes their tongue against or between their front teeth while swallowing, speaking, or even at rest. While tongue movement is a normal part of daily function, the direction and pressure of that movement make all the difference. In healthy development, the tongue should press against the roof of the mouth. However, in children with tongue thrusting, the tongue moves forward instead—often resulting in visible and lasting dental changes.

Skye Canyon pediatric dentists are trained to recognize early signs of tongue thrusting because it can significantly impact a child's bite, speech development, and overall oral health. Early intervention is key to preventing more serious complications down the road.

Causes of Tongue Thrusting in Kids

Prolonged Pacifier or Thumb Sucking

When children continue to use pacifiers or suck their thumbs beyond infancy, it can influence how their tongue and jaw develop. These habits encourage the tongue to push forward, creating a pattern that often persists during swallowing and speech. Over time, this can disrupt normal tongue positioning and lead to tongue thrusting.

Enlarged Tonsils or Chronic Mouth Breathing

Children with enlarged tonsils or persistent nasal congestion often resort to mouth breathing. This changes tongue posture by keeping it low and forward in the mouth, which can interfere with the natural development of swallowing and speaking patterns. A Skye Canyon pediatric dentist may refer children to an ENT specialist if airway obstruction is suspected as a contributing factor.

Tongue-Tie (Ankyloglossia) or Oral Muscle Imbalances

Tongue-tie is a condition where the strip of tissue connecting the tongue to the bottom of the mouth is too short or tight, limiting proper tongue movement. This restriction can prevent the tongue from resting or moving correctly, leading to compensatory behaviors like tongue thrusting. In some cases, muscle imbalances in the face or mouth also contribute to this issue and require coordinated care.

Delayed Weaning from Bottles or Sippy Cups

When children continue to use bottles or sippy cups well past the recommended age, they may develop incorrect swallowing techniques. These methods can mimic infantile swallowing patterns, reinforcing tongue thrust behavior. A Skye Canyon pediatric dentist can guide parents on when and how to transition their child to regular cups to support proper oral development.

Dental Consequences of Untreated Tongue Thrust

Open Bite and Misaligned Teeth

One of the most visible consequences of tongue thrust is the development of an open bite—a condition where the upper and lower front teeth do not touch when the mouth is closed. This misalignment affects not only the look of the smile but also how a child chews and speaks. Tongue thrusting can also cause crowding, spacing, or protrusion of teeth, leading to the need for orthodontic treatment.

Speech Difficulties and Lisping

Children with tongue thrust often experience speech problems, especially a frontal lisp. This occurs when the tongue pushes forward while trying to make certain sounds like “s” or “z,” causing unclear or distorted speech. Over time, these speech patterns can become ingrained, requiring both dental and speech therapy to correct.

Changes in Jaw Growth and Facial Development

Chronic tongue thrusting can affect more than just the teeth—it can influence how the jaw and face develop. Abnormal pressure from the tongue can lead to longer facial structures, narrow dental arches, and improper bite alignment. These developmental changes may require early orthodontic or orthopedic intervention to guide proper jaw growth.

How Skye Canyon Pediatric Dentists Detect Early Warning Signs

A skilled Skye Canyon pediatric dentist will look for red flags such as abnormal swallowing patterns, speech irregularities, and changes in bite or tooth alignment during regular dental exams. By catching these signs early, the dentist can recommend appropriate therapies or refer to specialists when needed—often reducing the need for more invasive treatment later on.

How a Skye Canyon Pediatric Dentist Diagnoses Tongue Thrust

Visual Exam of Tongue Position and Bite Alignment

During a routine dental visit, the pediatric dentist will begin by examining the position of the tongue at rest, during speech, and while the child swallows. They will also check for signs of an open bite or other bite misalignments that are commonly associated with tongue thrust. This hands-on evaluation offers valuable clues about how the tongue and teeth are interacting.

Observation During Swallowing and Speech

The dentist may ask your child to perform simple tasks like sipping water, counting, or saying certain words. These exercises help observe whether the tongue pushes forward against or between the teeth. A Skye Canyon pediatric dentist is trained to spot subtle thrusting behaviors that often go unnoticed by parents or caregivers.

Collaboration with Orthodontists or Speech-Language Pathologists if Needed

In many cases, a team-based approach yields the best results. If tongue thrust is affecting your child’s speech or if advanced orthodontic concerns are present, the pediatric dentist may refer you to a speech-language pathologist (SLP) or orthodontist. Working together, these professionals can develop a personalized treatment plan to correct the issue and support healthy development.

Use of Dental Imaging to Assess Structural Impact

If structural concerns are suspected—such as a narrow palate, misaligned jaw, or abnormal tooth positioning—the dentist may recommend digital X-rays or other imaging. These tools allow a Skye Canyon pediatric dentist to evaluate bone and tooth development and track changes over time as treatment progresses.

Diagnosing tongue thrust early makes a big difference. With the help of an experienced pediatric dentist in Skye Canyon, your child can receive the right interventions to protect their smile, speech, and confidence.

Treatment Options for Tongue Thrust in Children

Myofunctional Therapy to Retrain Tongue and Facial Muscles

Myofunctional therapy involves targeted exercises that help children learn proper tongue posture and function. These exercises strengthen the muscles of the mouth, tongue, and face, and teach the child to swallow correctly. A Skye Canyon pediatric dentist may work with a certified orofacial myologist to guide your child through this therapy for lasting results.

Orthodontic Solutions for Bite Correction

When tongue thrusting has led to an open bite or misaligned teeth, orthodontic treatment may be necessary. Appliances such as tongue cribs or habit breakers can gently discourage the forward movement of the tongue and guide the bite into proper alignment. In more advanced cases, braces or other orthodontic systems may be recommended to restore function and aesthetics.

Speech Therapy for Associated Articulation Issues

If tongue thrusting has affected your child’s speech—particularly causing a lisp or articulation difficulties—a speech-language pathologist (SLP) may be brought in as part of the treatment plan. Speech therapy helps correct the way the tongue moves during speaking and reinforces the healthy patterns learned through myofunctional therapy.

Monitoring and Follow-Ups by a Skye Canyon Pediatric Dentist

Ongoing care and monitoring are key to success. A Skye Canyon pediatric dentist will schedule regular follow-up visits to track progress, check for any recurrence of tongue thrusting habits, and adjust the treatment plan as needed.  


Preventing Long-Term Effects with Early Intervention

Importance of Early Dental Checkups and Oral Habit Evaluations

Regular dental visits starting at an early age allow pediatric dentists to monitor oral development and detect signs of tongue thrust before it causes major issues. A Skye Canyon pediatric dentist will evaluate swallowing patterns, tongue posture, and other oral habits during routine checkups.


Replacing Prolonged Pacifier or Bottle Use with Healthier Habits

One of the best ways to prevent tongue thrusting is to wean children off bottles and pacifiers at the appropriate developmental stage. Skye Canyon pediatric dentists typically recommend transitioning to open cups around 12–18 months and discouraging pacifier use beyond age two. Replacing these habits with positive oral routines can help children develop proper swallowing and speech patterns.

Tips from Skye Canyon Pediatric Dentists for Guiding Proper Tongue Posture at Home

Parents play a key role in reinforcing healthy oral habits. Pediatric dentists in Skye Canyon often provide practical advice for at-home support, such as:

  • Encouraging children to keep their lips closed and breathe through their nose
  • Practicing tongue exercises during brushing time
  • Using story-based or visual tools to teach correct tongue posture
  • Monitoring speech and feeding behaviors for signs of thrusting

Creating a supportive home environment makes it easier for children to develop new muscle memory and overcome the habit naturally.

How Early Treatment Supports Long-Term Oral Health and Development

Children who receive early treatment for tongue thrusting are less likely to need extensive orthodontic work or speech therapy later in life. Addressing the root causes early promotes healthier tooth alignment, stronger facial structure, and better communication skills. A Skye Canyon pediatric dentist can provide a roadmap for treatment that not only solves current concerns but also sets your child up for lifelong oral wellness.
