A child's smile is shaped by more than brushing and flossing. Sometimes, a small everyday habit involving the tongue can influence how their teeth develop. Here's what parents should know about tongue thrust and its connection to children's dental health.
When you think about your child's dental health, you probably think about brushing twice a day, limiting sugary snacks, and keeping up with regular dental checkups. But have you ever paid attention to where your child's tongue rests when they swallow, speak, or simply relax?
It may seem like a small detail, but tongue positioning plays an important role in oral development. One habit that pediatric dental professionals pay attention to is called tongue thrust.
Although it may go unnoticed for years, tongue thrust can sometimes be associated with changes in tooth alignment, bite development, and speech patterns. Understanding what it is and recognizing potential warning signs can help parents take a proactive approach to their children's oral health.
Let's explore what tongue thrust is, why it matters, and when it's worth bringing up at your child's next dental appointment.
What Exactly Is Tongue Thrust?
Tongue thrust, also known as a tongue thrust swallow, is a swallowing pattern in which the tongue moves forward and pushes against or between the front teeth instead of resting in a more typical position.
During normal swallowing, the tongue generally works against the roof of the mouth to help move food and liquids toward the throat. With tongue thrust, the tongue may move forward toward the front teeth during swallowing. In some children, the tongue may also rest too far forward when the mouth is relaxed.
It's important to understand that tongue thrust is not automatically a problem in babies and very young children. Infant swallowing patterns naturally differ from those of older children and gradually develop as oral muscles mature.
However, if a forward tongue posture or swallowing pattern continues as a child grows, it may be worth having it evaluated.
How Can Tongue Thrust Affect Your Child's Smile?
The tongue is a surprisingly powerful muscle. It works throughout the day during speaking, eating, swallowing, and resting. Its position and the frequency of pressure against the teeth can play a role in how a child's smile develops.
According to the American Academy of Pediatric Dentistry (AAPD), tongue thrusting and abnormal tongue positioning may be associated with several dental and developmental concerns.
Here are some potential effects:
1. An Open Bite
One of the dental conditions associated with tongue thrust is an anterior open bite.
This occurs when the upper and lower front teeth do not meet when the back teeth are together. A child may have a visible space between their front teeth even when their mouth is closed.
An open bite can sometimes make biting into foods, such as sandwiches or apples, more challenging.
2. Protruding Front Teeth
When the tongue repeatedly rests against or pushes forward on the front teeth, it may contribute to changes in their position over time.
Some children may develop upper front teeth that appear more prominent or angled outward.
3. Changes in Bite Alignment
Tongue thrust may be associated with other bite irregularities, including changes in how the upper and lower teeth fit together.
Because children's jaws and permanent teeth are still developing, monitoring bite alignment during routine dental visits can be helpful.
4. Speech Difficulties
Tongue positioning is also important for producing certain sounds.
Some children with tongue thrust may have difficulty pronouncing sounds such as "S" and "Z" clearly. They may develop an interdental lisp, which occurs when the tongue moves between the teeth during speech.
Not every child with a speech difficulty has tongue thrust, and not every child with tongue thrust experiences speech problems. However, when these concerns occur together, an evaluation may help identify whether they are connected.
5 Signs Parents Should Look Out For
Tongue thrust can be difficult to recognize because many of its signs happen during everyday activities.
Here are five things parents can watch for:
1. The tongue pushes between the teeth.
You may notice your child sticking their tongue between their upper and lower front teeth when swallowing or speaking.
2. An open-mouth resting posture.
Your child frequently keeps their mouth open or their lips apart when they are not talking or eating. This can have several possible explanations, including nasal congestion or other breathing-related concerns.
3. Difficulty pronouncing certain sounds.
Listen for persistent difficulty with sounds such as "S" and "Z," especially if the tongue appears to move forward between the teeth.
4. Visible changes in tooth alignment.
You may notice a gap between the upper and lower front teeth when your child bites down, or front teeth that appear to angle outward.
5. Unusual swallowing movements.
Some children visibly push their tongue forward or tighten their lips and facial muscles when swallowing food, liquids, or even saliva.
Remember, these signs do not automatically mean your child has tongue thrust. They are simply reasons to pay closer attention and discuss any concerns with a dental professional.
What Causes Tongue Thrust in Children?
There isn't always one clear explanation for tongue thrust. It can be related to a combination of oral habits, muscle patterns, structural differences, and other developmental factors.
Some possible contributing factors include:
Prolonged oral habits: Extended thumb sucking, pacifier use, or other repetitive sucking habits may influence oral muscle patterns and dental development.
Mouth breathing: Children who have difficulty breathing comfortably through their nose because of allergies, enlarged tonsils, or other airway concerns may develop different tongue and mouth resting positions.
Oral muscle coordination: Some children may have difficulty coordinating the movements of their tongue, lips, and facial muscles during swallowing and speech.
Structural differences: Differences in oral anatomy, including a restricted tongue movement, may contribute to certain oral and swallowing patterns.
It's important not to assume that one of these factors is responsible without an appropriate evaluation. Every child's oral development is different.
Can Tongue Thrust Be Corrected?
Yes! When tongue thrust is affecting a child's dental development or everyday functions, there are several approaches that may help.
The right treatment depends on your child's age, oral development, symptoms, and the underlying factors contributing to the habit.
A pediatric dentist may recommend one or more of the following:
Dental Monitoring: Regular dental examinations allow the dentist to monitor tooth alignment, bite development, and changes in oral habits as your child grows.
Myofunctional Therapy: Specialized exercises guided by a trained orofacial myofunctional professional may help children develop better coordination and positioning of the tongue, lips, and facial muscles.
Speech Therapy: If tongue positioning is affecting speech or swallowing, a speech-language pathologist may evaluate your child and recommend appropriate therapy.
Orthodontic Evaluation: If tongue thrust is associated with an open bite, protruding teeth, or other alignment concerns, an orthodontist may evaluate whether early orthodontic intervention is appropriate.
Addressing Underlying Concerns: If nasal obstruction, allergies, enlarged tonsils, or other breathing-related issues are contributing to an abnormal resting posture, a referral to an appropriate medical specialist may be helpful.
Not every child needs treatment, and appliances or orthodontic intervention are not automatically necessary. The goal is to identify whether the habit is affecting your child's development and create an individualized plan when needed.
Why Early Dental Checkups Matter
Children's smiles change significantly as they grow. Baby teeth gradually make room for permanent teeth, jaws develop, and oral muscles learn new patterns.
This is why regular pediatric dental visits are about much more than checking for cavities.
During a dental examination, a pediatric dentist can evaluate your child's teeth, bite, and oral development, identify unusual habits, and determine whether further evaluation is necessary.

Your child's tongue may be small, but its role in oral development is anything but insignificant!
Tongue thrust doesn't necessarily mean something is wrong, and not every child who pushes their tongue forward will develop dental problems. However, recognizing unusual tongue positioning, swallowing patterns, or changes in tooth alignment can help parents know when to seek professional advice.
If you've noticed any of these signs, consider bringing them up at your child's next dental appointment.
