Dr. David S. Alleman, DDS has over 40 years of experience as a dentist, currently practicing in Utah, USA. After seeing the results of traditional dentistry — symptomatic restorations that failed over time — he spent over eleven years pioneering the development of noninvasive dental procedures that addressed these concerns while conserving tooth structure. Dr. Alleman has condensed over 1,400 research articles into his Six Lessons Approach to Biomimetic Restorative Dentistry. This approach offers dentists a set of protocols to perform biomimetic restorations start to finish, providing alternatives to full coverage crowns and an end to sensitivity and recurring retreatment. Dr. Alleman has been practicing and teaching biomimetic restorative dentistry for over 20 years.
