Dr. Steve Duffin Wins the Inaugural Big Idea Challenge for his simple device ‘NoDK’ which Eliminates Tooth Decay

Winners of the First Big Idea Canvas Challenge were announced yesterday with the first prize awarded to NoDK (pronounced No Decay), a simple device to eliminate tooth decay. Tooth decay, or caries, is a leading health concern throughout the world with millions of children and adults having little or no access to dental care. NoDK is a pen-like device that can easily be dispensed in a cavity, stopping pain and bacterial decay with over 95% effectiveness.   

Dr. Steve Duffin is a dentist and a microbiologist who has devoted his career to working in public health settings. For years, Dr. Duffin has been researching methods to stop tooth decay using a device that applies a medicine rather than shots and fillings. Dr. Duffin has now achieved a major breakthrough and has patented technology that is based on the application of silver nitrate, used over one hundred years ago, combined with a modern fluoride varnish.

Together when applied in a specific manner, tooth decay is arrested and new decay is greatly diminished.   

With the NoDK system, there is no need for shots or drills. This simple and painfree system removes the fear that patients feel when going to see the dentist.

Millions of children go to school each day with tooth pain. Untreated caries is the most prevalent malady of humans globally,” said Dr. Duffin. He has invented a simple, safe, and effective method to treat people outside of a dental office, even without electricity. Working with his son, Marcus, Dr. Duffin designed a medical device to facilitate this process anywhere on earth.

He added, “We are delighted that the Big Idea Challenge has been able to provide a spotlight to this important breakthrough.” Dr. Duffin noted, “We hope very soon the NoDK will be globally available, and we look forward to checking the caries problem off the list of global epidemics.”
