Ark 3/4″Yellow Lip Blok mouthpieces are simple yet effective oral motor tools.


They naturally exercise the mouth muscles to discourage tongue-thrusting, promote tongue retraction, and correct overall tongue positioning. They also prevent individuals from biting the straw or putting it too far into their mouths. Simply press them into the top of a straw, and drink.The length of the yellow is 3/4″.

This hierarchy slowly teaches individuals to put less and less of the straw into their mouths. When only 1/4” is inside the mouth, fluid is deposited in the front of the mouth where it is easier to manage and less likely to cause coughing or aspiration. With shorter lengths, you also get a better oral motor workout, as the tongue retracts more, the lips seal better, and the cheeks have more tension.
