Tongue thrusting may seem like a small habit, but over time it can affect how the teeth line up, how a child speaks and how food is swallowed. Many parents notice it only when the front teeth start to stick out or a gap appears between the upper and lower teeth. Finding a dentist for tongue thrusting in Chennai early can help correct the habit before it causes bigger bite and speech problems.
At Dr. Hari’s Dental Centre in Medavakkam, tongue thrusting is assessed and treated by a team that includes pediatric dentists and an orthodontist. This page explains what tongue thrusting is, its signs and causes, how it is treated, and what to expect when you visit.
What is Tongue Thrusting?
When we swallow, the tip of the tongue normally presses against the roof of the mouth, just behind the upper front teeth. In tongue thrusting, the tongue pushes forward against the front teeth, or between the upper and lower teeth, during swallowing, speaking or even at rest.
All babies swallow with the tongue forward. This is called an infant swallow, and it is normal during breastfeeding and bottle feeding. Most children slowly change to a mature swallow between the ages of 4 and 6. When the forward pattern continues beyond this age, it is called tongue thrusting, or an oral myofunctional problem.
A person swallows about 1,000 to 2,000 times a day. Each forward push is gentle, but repeated many times every day, it can slowly move the teeth and change the shape of the bite.
Types of Tongue Thrusting
- Anterior tongue thrust: The tongue pushes against or between the front teeth. This is the most common type and often causes the upper front teeth to flare out or leaves a gap between the front teeth when biting (an open bite).
- Lateral tongue thrust: The tongue pushes out to one or both sides, between the back teeth. This can stop the back teeth from meeting properly.
- Bilateral or complete tongue thrust: The tongue pushes forward at the front and the sides. Only the back molars may touch when the mouth is closed.
Signs of Tongue Thrusting
Parents can look for these signs in their child:
- The tongue is seen between the teeth while talking, swallowing or resting
- The mouth often stays open, with the lips apart
- Breathing through the mouth, especially during sleep
- A lisp, where “s” and “z” sound like “th”
- Difficulty saying sounds such as “t,” “d,” “n” and “l”
- Messy eating, or pushing food forward while chewing
- Front teeth that stick out or have gaps between them
- The upper and lower front teeth do not meet when biting
- The lips or chin muscles tighten during swallowing
- Thumb sucking or finger sucking that continues after age 4
A dentist for tongue thrusting in Chennai can check these signs during a simple examination and confirm whether tongue thrusting is present.
Causes of Tongue Thrusting
Tongue thrusting usually has more than one cause. Finding the cause helps a dentist for tongue thrusting in Chennai plan the right treatment.
Narrow Palate
A narrow or high arched palate leaves less room for the tongue to rest against the roof of the mouth. The tongue then sits lower and pushes forward during swallowing and speech. Over time, this forward pressure affects tooth position. Orthodontic treatment to widen the upper jaw may be needed to give the tongue enough space.
Oral Anatomy
Some children are born with oral features that make tongue thrusting more likely, such as a short jaw, a shallow palate or uneven dental arches. These differences can guide the tongue into the wrong resting position. An early check by an orthodontist can find these features and plan appliances or exercises to retrain the tongue.
Enlarged Tonsils or Adenoids
Large tonsils or adenoids can block the airway and make breathing through the nose difficult. The child starts breathing through the mouth, and the tongue moves down and forward to keep the airway open. This posture can become a habit even after the tonsils or adenoids are treated. In such cases, the dentist may advise a check with an ENT doctor along with habit correction.
Tongue Tie (Ankyloglossia)
In a tongue tie, the thin band of tissue under the tongue (the lingual frenulum) is too short or tight. This limits how high the tongue can lift, so it cannot rest against the palate. The restricted movement can lead to forward thrusting during swallowing and can make speech and orthodontic correction harder if it is not treated.
Long Use of Bottles, Sippy Cups or Pacifiers
Sucking on a bottle, sippy cup or pacifier trains the tongue to push forward. If these are used well beyond infancy, the forward pattern can become fixed. Slowly stopping these habits and starting simple exercises early can help prevent long term problems.
Thumb and Finger Sucking
Long term thumb or finger sucking pushes the front teeth forward and creates space that the tongue then fills. Thumb sucking and tongue thrusting often go together, so both habits may need to be treated.
Allergies and Blocked Nose
Frequent colds, allergies or a blocked nose can lead to mouth breathing. Like enlarged tonsils, this keeps the tongue low and forward.
By finding and treating these causes early, the tongue can be retrained to rest in the right position, and more complex orthodontic treatment may be avoided later.
Effects of Tongue Thrusting if Left Untreated
- Open bite: The upper and lower front teeth do not meet, making it hard to bite into food.
- Flared front teeth: The upper front teeth tip forward and gaps appear between them.
- Speech problems: Lisping and unclear sounds that may affect confidence at school.
- Swallowing difficulty: Food may not be pushed back smoothly during swallowing.
- Changes in facial appearance: Long term mouth breathing and tongue thrust can affect the shape of the face and lips.
- Relapse after braces: If tongue thrusting is not corrected, teeth moved with braces can shift back after treatment.
How Tongue Thrusting is Diagnosed
At Dr. Hari’s Dental Centre, the dentist first talks with parents about the child’s habits, feeding history, breathing, sleep and speech. The examination then includes:
- Watching the child swallow water or saliva, and checking where the tongue moves
- Checking the bite, the position of the front teeth and the shape of the palate
- Looking at the tongue tie, tonsils and lip posture
- Listening to how the child says certain sounds
- Taking photographs, models or X rays of the teeth and jaws if needed
Based on these findings, the dentist explains the type of tongue thrust, its likely causes and the treatment choices.
Treatment for Tongue Thrusting
Treatment depends on the child’s age, the cause of the habit and how much the teeth have already moved. Often, more than one treatment is used together.
Tongue Exercises (Myofunctional Therapy)
Simple daily exercises teach the tongue to rest and push in the right place. Common examples include:
- Spot exercise: Placing the tip of the tongue on the small ridge just behind the upper front teeth and holding it there.
- Swallow practice: Swallowing small sips of water while keeping the tongue tip on that spot and the teeth together.
- Elastic exercise: Holding a small orthodontic elastic between the tongue tip and the palate while swallowing.
- Lip exercises: Gentle exercises to help the lips stay closed at rest.
These exercises work well when done every day at home with a parent’s help. The dentist checks progress at each visit and adds new steps over time.
Habit Breaking Appliances
For children who continue to thrust, a small appliance may be fitted inside the mouth. A tongue crib or palatal reminder sits behind the upper front teeth and gently reminds the tongue to stay back. These appliances are usually worn for several months while the new habit forms. Your dentist will explain how to care for the appliance and what your child can eat.
Orthodontic Treatment
If the teeth have already moved, braces, clear aligners or a palatal expander may be needed to correct the bite. An orthodontist for tongue thrusting in Chennai plans this treatment alongside habit correction, so the teeth stay in place after treatment.
Tongue Tie Release
If a tongue tie is limiting tongue movement, a minor procedure called a frenectomy may be advised to release it. Exercises after the procedure help the tongue learn its new range of movement.
Speech Therapy and Medical Referrals
If the child has a lisp or other speech difficulties, the dentist may advise working with a speech therapist alongside dental treatment. If enlarged tonsils, adenoids or allergies are causing mouth breathing, an ENT or medical check may be suggested. Treating the cause together with the habit gives a better chance of lasting change.
When Should Your Child Be Checked?
- If tongue thrusting signs are still seen after age 5 or 6
- If thumb sucking or pacifier use continues after age 4
- If the front teeth are flaring out or not meeting
- If your child breathes through the mouth most of the time
- If your child has a lisp or unclear speech
- Before starting braces, to make sure the habit is corrected first
An early visit to a dentist for tongue thrusting in Chennai can make treatment simpler and shorter, since the jaws are still growing and habits are easier to change in young children.
Tongue Thrusting in Adults
Tongue thrusting is not only a childhood problem. Some adults have never outgrown the habit, and others develop it after tooth loss or gum problems. In adults, tongue thrusting may cause spacing between the front teeth, a worsening open bite or teeth shifting after braces. Treatment for adults usually combines tongue exercises with orthodontic care, and gum treatment if the supporting bone has been affected. Adults with these signs can also see a dentist for tongue thrusting in Chennai for an assessment.
