Trustworthy Information

We’ve worked hard to provide you with trustworthy oral health information on ToothIQ.com. We started by creating unbiased dental information, having it peer reviewed, and then having it certified trustworthy by the world renowned healthcare website certification organization Health on the Net Foundation (HON) in Geneva, Switzerland (which sadly ceased operating on December 15, 2022). We initially were certified even before launching ToothIQ.com in 2008 and were proud to have been re-certified in subsequent years.

This website is certified by Health On the Net Foundation.

  • Thomas J. Greany, DDS • Assistant Professor, Clinical Track, University of Colorado Denver School of Medicine • Denver, Colorado
