About Your Dentist

Duane Keller, DMD

“Most patients that are referred to my office have already received some form of treatment as the cause of their problems have not been corrected. The first thing we will do is find out why you are in pain or have a problem. Over the last 40+ years I have developed, tested, utilized and have patented many of the methods you will find on this website. These were developed because “conventional” methods did not prove sufficient to meet the patient’s needs.”  

Meet Dr. Duane Keller 

For over 40 years, Dr. Duane Keller has been an instrumental part in treating patients with TMJ and other head and neck pains. He has been active in developing treatments for periodontal “gum” disease as well. He has invented, patented, and taught the TMJ Orthodontic Method, and he has invented, patented, and teaches world-wide the Perio Protect™ Method of treating periodontal disease and gingivitis. Dr. Keller focuses on non-surgical TMJ and chronic pain treatment. Dr. Keller developed these TMJ methods because he and his wife Carol had TMJ problems that were caused by treatments received while in dental school and he had to learn how to correct and manage these injuries with first-hand knowledge. The Perio Protect™ Method was developed as a result of Dr. Keller’s mother requesting a different method of treatment as periodontal surgery was too painful.

Dr. Keller and his staff have a deep passion for every patient that enters our practice. We have a very caring office environment.
