This manual is a fun and practical resource to fix tongue thrust, together with the set of appropriate tools. The SMILE (SysteMatic Intervention for Lingual Elevation) Program, developed by Robyn Merkel-Walsh, targets speech and swallowing skills in a 14-step hierarchy. Designed for children 7-12, yet appropriate for teens and adults, the manual is illustrated with “Mr. Smile” pictures to better visualize the techniques.
