Our story

When we founded ONVI, makers of Prophix, our goal was simple yet powerful: We wanted to help people better see and understand what was going on in their mouths. We believed that this would, in turn, help them improve their oral health care habits. 

Prophix inventor, Dr. Craig Kohler, has been at the forefront of dental innovation for over twenty  years—and he’s among the few dentists in the country who use live video to deliver premium care to patients. He realized that if people could actually see what they’re doing while brushing at home, they would be able to clean their teeth more thoroughly and consistently—especially those spots that are hard to see (and commonly overlooked).

That idea blossomed into Prophix a video toothbrush that lets you see and take pictures while you brush. We designed multiple attachments so you can craft a personalized oral care routine that suits your specific needs. And we took customization one step further with an app that lets you see how you’re doing with your routine and get tips to improve it.


“I just love being a dentist. And when I was sitting and looking at what my life might be for the next ten to fifteen years … I’d rather develop something that helps people. Prophix was a natural extension of seeing a problem that people had and being willing to say, You know, this will truly make a difference.”

“I’ve been a practicing dentist for over 35 years. I truly believe that when people see what they are cleaning and they’re able to partner with a dental health professional, they’re going to have a healthier mouth, which in turn leads to a healthier body.”
