Paint the tongue and value swallowing!

Do you value swallowing and want to know what happens "inside" the mouth? The concentrated fluorescent substance will be your ally to perform the Payne Technique. Stain the tongue and you will be able to objectify the swallowing process and detect abnormal spots. Don't get lost, you need a black light lamp to illuminate the "fluor" tongues. Available in neutral and strawberry flavor. We recommend that you purchase the recording block to record your results and compare your ratings.
