General Information

 After practicing endodontics for 25 years in Grass Valley, California, involvement with horses led Dr. Warren to seek a different and less congested environment.  Horsemanship clinics in Modoc County and a love for the high desert climate made relocation an easy decision, culminating with the 2004 purchase of the Kelley Ranch in Alturas, California, and the opening of his Klamath Falls endodontic practice in 2006. Dr. Warren relocated his residence to Midland, Oregon in 2010.

Dr. Warren graduated from dental school at the University of California, San Francisco, in 1977. After two years in general practice, he entered residency training and obtained a Master of Science degree and his Certificate in Endodontics from The Ohio State University in 1981.  He is a career long participant in organized dentistry, having served as president of the Butte-Sierra District Dental Society and as a 12 year member of the House of Delegates of the California Dental Association. Dr. Warren continues to serve organized dentistry as a Delegate to the 2014 Oregon Dental Association House of Delegates, and he is currently a member of the Oregon Dental Association Leadership Development Committee.

“My practice philosophy includes delivery of the best care I am able to provide, compassion for apprehensive patients and making every effort to eliminate all discomfort for each patient.”  Nitrous oxide/oxygen inhalation analgesia (laughing gas) and oral sedatives are available when needed.  Dr. Warren utilizes the most advanced techniques, including the endodontic operating microscope, ultrasonics, nickel titanium rotary instrumentation, and digital radiography.  “I greatly appreciate what technology has done to upgrade the quality and delivery of endodontic care”.

Endodontic success depends upon location and management of complicated root canal anatomy, through chemomechanical debridement of canal systems, and sealing of both the root system and the occlusal aspects of the tooth.  To that end, I have found that vertical condensation of warm gutta percha, along with the associated preparation shape and debridement process, offer the best results. During the initial years of my endodontic practice career, we managed many failed endodontic cases with a surgical treatment approach, and many of those cases would again show signs of failure. With increased understanding of canal system anatomy and enhanced technology, indications for endodontic surgical treatment have been reduced by the ability to complete nonsurgical retreatment. Retreatment is difficult, and meeting this challenge can involve dismantling/removal of posts, cores, and crowns, removal of separated instruments, and removal of metal and plastic thermafil carriers and silver points.  With the utilization of ultrasonics and surgical operating microscope, many difficult retreatment cases can be completed successfully, providing an excellent benefit to the patient and a feeling of great accomplishment for the practitioner.
