Tongue Thrust
Atypical / Reverse Swallow
Try to retract your cheeks with your fingers, bite your teeth, and smile - now try to swallow while in this position. Was it difficult? Now try to put a small amount of water in your mouth, bite your teeth, and smile - now try to swallow while in this position. Were you able to do so without closing your lips or using your cheek/neck muscles? If not, you might have a tongue thrust / atypical swallow. This looks and feels different to everyone.
What are the potential signs / symptoms?
Tongue thrust, or atypical / reverse swallow, is when the tongue pushes against the teeth or between them during swallowing. This may happen when the tongue is tied or it has learned a low posture pattern from non-nutritive sucking (thumb, finger, pacifier) or bottle feeding. The tongue should brace in the space behind your upper front teeth and carry the motion backward when swallowing.
​

Below are a few examples of before and during a swallow while retracted with a smile. Notice the tension around the lips and the tongue coming forward. They are in order from mild to severe.
(The fourth example couldn't complete the swallow while retracted as they rely on their facial muscles).
Before retracted swallow:
During retracted swallow:
Unable to swallow retracted

What should I do about it?
Let's start with an initial assessment to ensure we know which exact goals we need to meet and how long we need to reach them! If your child is under five years old, it may be recommended to start with a Myo Munchee Mini program until they can withstand a complete myofunctional therapy program. Sometimes a thrust can resolve with the Myo Munchee + mini myo program alone! Sometimes orthodontics is needed to close the spaces but addressing the muscle imbalance and thrust before and during orthodontics is important to create a stable environment. Myofunctional therapy benefits speech therapy for clients with a thrust and/or tongue tie.
