Episode 161: How Do You Get Rid of Bad Breath?

Meet the Expert: Dr. Mel Rosenberg, Professor Emeritus Tel Aviv University, inventor, children’s book author

Professor Mel Rosenberg

When I was young, I dreamed of being a children’s book writer and musician. Instead I became a scientist and inventor. My Ph.D. dealt with the ability of certain microorganisms to adhere to oil droplets. I went on to invent a two phase oil-water mouthwash which in turn led me to study the causes and treatment of bad breath. In my forties, I began to publish my children’s books, and to perform as a jazz musician and singer. Nowadays I give lectures and courses on a variety of subjects and teach others to be successful international speakers.

As a scientist, I spent most of my career as a microbiologist at Tel Aviv University studying how to measure, diagnose and treat bad breath. I published and almost perished, having smelled the breath, armpits and feet of well over 5,000 people. Maybe 10,000, but who’s counting?

As an inventor I failed quite often, causing some explosions and surviving one test crash. But I did manage to invent a two-phase mouthwash which became popular in the UK, the US and elsewhere.
