About ToothIQ and Symbyos

ToothIQ.com is developed and maintained by Symbyos (901 Front Street, Suite 220 Louisville, Colorado 80027 USA), founded in 2001 and dedicated to producing high-quality, trusted dental information for patients, dentists, and dental schools. We believe that information, choice, and transparency are the fundamental building blocks of optimal healthcare. When dentists and patients can communicate effectively, and patients can be empowered to participate in the treatment planning of their own oral health, a trusting bond is formed between doctor and patient – leading to value-based dentistry and better treatment outcomes.

The information provided on ToothIQ.com is designed to complement, not replace, the relationship between a patient and his/her own dental professional and/or physician.

Our clients (and select projects)

CU SDM logo

University of Colorado School of Dental Medicine

We have worked with the University of Colorado School of Dental Medicine to integrate dental videos into several of their processes to inform their students and patients, most recently integrating with its treatment planning process as part of the school’s meaningful use incentive. These innovative solutions were possible due to a close collaboration with CU SDM’s IT team, faculty, and third party software partners.

UT Health Sciences Center San Antonio logo

University of Texas Health Science Center San Antonio School of Dentistry

Symbyos works with the University of Texas Health Science Center San Antonio School of Dentistry to connect many ToothIQ topics to UT Health Science Center’s oral health evidence-based practice program’s searchable Critically Appraised Topics (CATs) database. For more information about CATs, please visit cats.uthscsa.edu.

Trustworthy Information - Health on the Net Certified

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.


The content on ToothIQ.com was primarily researched and written by Thomas J. Greany, DDS, co-founder of Symbyos LLC and currently Associate Professor (C/T), Director of Academic Technology Initiatives at the University of Colorado School of Dental Medicine in Aurora, Colorado.

Some content was written by Ken Lambrecht of Symbyos LLC. Ken also serves as the primary editor.
