The Dr Patrick Fellus is a retired Orthodontist who has worked in pediatric orthodontics for more than 40 years. He is a pioneer in the use of functional treatments in Orthodontics, and after years of practice he realized that swallowing was at the heart of all orofacial praxis. That is why he worked on the rehabilitation of swallowing; by experimenting, he found that the lips actually play a crucial role.
In 2012, after years of thinking, he eventually completed the reunion of all his ideas in one device : the FroggyMouth.
